Spring is finally around the corner here in what has been another frigid Utah winter. Indications are that it will be another good year with many new conversions hitting the road. I spoke with a customer today that finally has his BMW Z3 completed. He did a great job! EV Gearbox Magazine did an interview on it. The article link:


I've seen some other very professional conversions lately as well. One is in Australia. Keep up the good work everyone.

So what's new at EV Source? We now sell the full line of Elcon chargers. Each of the different models are great, and are helping bring down the cost of conversions without sacrificing power or quality. We've started putting together some new kits to make the job of converting easier. Some of these include forced air cooling kits for various motors, and controller packages. Let us know if there's anything your struggling with, and we'll get a kit put together to simplify the process. We'd like to get as many conversions on the road as possible!

October 12, 2009

I can't believe it has been almost a year since I wrote anything here! There has been so many new developments in the last year that time has gone by very quickly. EV Source is still alive and well, with lots of new products being carried, and more that will be coming in the next couple of months.

A year ago, I was talking about high power controllers becoming scarce. This season brings about a change for good in the industry with several companies beginning to produce quality products. There is quite a bit of excitement about the new NetGain Controls controller. It is listed on the EV Source site under the "Controllers" category, although it won't be on the shelf for probably another month. New high quality accessories are being provided with the controller such as different varieties of cooling kits and options for Hall-effect throttle inputs. It appears CafeElectric will also soon have controllers available again. They have moved production to a company in Washington. It sounds like they will be producing to demand. We will still be carrying the full CafeElectric line of products.

Some other great new products:

  • A complete vacuum assist kit that is *so* quiet and fast! We add a special diode to the kit to extend the life of the relay. The kit can be found on the braking page.
  • A new speed sensor solution is coming. It's more than just a speed sensor though, it's a complete system! See the speed sensor page for details.
  • A new line of more economical SW200-style contactors that have been found to perform comparable with the Albright SW200. They can be found on the contactors page.
  • EV Source now has a constant supply of new MR2 power steering pump kits. They can be found on the power steering page.
  • Many new off-the-shelf motor to transmission adapters are available. Also, EV Source now has the capability to make custom adapters! Check out the adapters page for details.

With all these new products available, it has never been easier to do your own EV conversion! I hope to see many new adventurous converters come out of the woodworks and take advantage of the great opportunity to run on electricity.

October 27, 2008

A little bit of bad news - CafeElectric controllers are being sold on a very limited basis right now. We still have a few that haven't been spoken for. Call or e-mail if interested. No Z2K's available at all.

We're hoping that LogiSystems will be able to take care of the 156V 1000A controller needs. They have slipped behind on shipments with their latest design modifications. We should start shipping out controllers again to those that have previously ordered the first couple weeks of November.

If anyone has an inkling to start a high current, high voltage controller business, now would be a good time! :)

August 11, 2008

For those of you that have kept an eye on this blog, you've probably been a bit dissapointed at the infrequent updates! But not to fear - it doesn't mean things haven't been happening here at EVS, on the contrary, things have been CRAZY! A good crazy, but sales have been high as interest in EV's has increased.

The website has had quite a few minor modifications, and several new products have been added. Recently, a customer made a suggestion about something they didn't like with the site, and it was changed within a few minutes of receiving the suggestion! So if you have ideas, let them be known!

EVS would like to welcome a new employee, Jesse Lopez. He brings a lot of excitement and experience that will benefit the industry.

That's it for now - got to get back to some other website updates.

February 25, 2008

The last couple of months have been absolutely swarming with activity! The number of conversions has seemed to spike, and general interest in gasoline-alternatives is on the rise. The EVS website has taken on some new changes. In an attempt to make product information easier to find, a documents section of the website has been created:


This page will gradually be expanded and re-worked to provide the simplest interface possible for obtaining technical support intormation.

December 24, 2007

2007 has been a great year here at EV Source. Many new projects have started and are taking shape. The EVS crew expanded from one ... me, the owner, to five, including Bruce Bohm as an assembler, Bryant Chandler as design consultant, assembler, and project assistant, Steve Bohm as book keeper and financial advisor, and Ashley Chandler as shipping department assistant. As you can probably tell from the list of names, EVS is a family business! I'm confident that 2008 will be another good year with more growth and expansion into new products and ideas that will help further the growth, availability, and feasibility of battery-powered electric vehicles.

As noted on the EVS homepage, we'll be closed until the 3rd of January for a much needed vacation! Orders can still be placed on-line, however, nothing will ship until the 4th of January. If questions should arise, I'll be answered e-mails on a limited basis. Feel free to e-mail, but I can't promise prompt replies!

Have a great holidays, be safe, and I'll see you again in 2008 for another great year!

August 30, 2007

Another new exciting product - the Tyco Kilovac LEV200 contactor, model number LEV200H4ANA and LEV200A4NAA (with and without auxiliary contacts). This is especially great news for the high-voltage crowd. The contactor will work up to 900VDC and is rated to break 2000 amps once at 320V! It is hermetically sealed, so it can be placed inside battery boxes. It comes in a very nice, solid, elegant package. The coil draws about 1A at 12V. And the best news of all ... the version without auxiliary contacts starts at under $100! We'll be sure to stock up and carry plenty so they are consistently in stock - they have already been selling well.

Here's the link to the website page:


Keep a watch out for more high-voltage friendly compatible components!

August 16, 2007

Three months is becoming the norm for how often I post here! I can't believe how time flies! Many good things have been happening this summer at EV Source. You might have noticed some changes with the website. They are subtle, but important. About 80% of all the product listings now have an *accurate* display of the stock on hand. For awhile, this was being updated manually. With the increased number of products being carried, it became evident that this wasn't going to work for long! So a back-end system was developed to tie the EV Source inventory database to the website. So next time you place an order, take a look at the stock on hand before and after your purchase. If the product is in that 80% that is tied to the back-end, then it will decrease by the number you purchased! The remaining 20% should be complete within the next couple of weeks.

For those of you that are following the Cluster charger, the first beta unit has been in a customer's hands for over a month now. He has given several positive comments, and seems to be happy with the unit. I've also received some very good constructive criticism. Some of this deals with software, some with the hardware - all of which is being considered, or has already been implemented. The second beta unit will be shipping within the next week. The Cluster should be hitting the website and available for sale to the general public within the next month or two. It will still remain in the beta stage for several more months, however, buyers won't be considered part of the beta testing team (which means you won't get your brains picked out for advice/troubleshooting!).

Finally, several other products have been added. Check out the following:

Hybrid Lead-Copper terminals
WarP 9 Mounting Plates
PakTrakr Monitoring System

Keep an eye out for more exciting product releases and updates to the EVS website!

May 22, 2007

Wow, has it really been three months since I posted! Lot's has happened in that time. New products have been added (although some are not yet on the website), the first beta Cluster unit is about ready to ship, and sales have been picking up rapidly!

Just one quick note - EV Source now has a package that includes most components necessary for a basic low-voltage conversion. The kit can be seen here:


More kits will be added in the future. Hopefully, there will be batteries, adapter plates, couplers, and motor mounts included as well (currently, these are not offered).

February 21, 2007

Several more Manzanita Micro chargers are in stock and ready to ship!

Browse the EV Source Top-Line Shop for several new, updated product photos. All new photos have a close-up available by clicking on the thumbnail.

The Cluster unit has been progressing well. Things slowed down some over the last few weeks as EV Source has moved to a new location which will help facilitate development. The new EV Source address is:

EV Source
430 E. 1200 N.
Logan, UT 84341-8422

Remaining items with the Cluster are mostly reliability testing, software features, and general debugging. I anticipate that beta units will be available to ship by mid to late March. I've been promising documentation ... it is almost to a point where I can release it for general public consumption. Another week ... or so!

Wireless solutions have been researched to allow for wire-free connection to retrieve data. The current favorite is BlueTooth. Although range is not as great, the simplicity and robustness of the protocol have been very appealing.

Finally, a new radiator is being used in the liquid cooling kit. It is designed for use under the hood (originally as a transmission fluid cooler). The overall size is slightly larger than the previous radiators, however, there are solid mounting feet that should make mounting the radiator much simpler and more robust.

A picture is always worth more than words:

The radiator will soon be available for sale separately on the liquid cooling page.

January 25, 2007

I have been working hard to get Manzanita Micro chargers in stock. Currently, I have a 20, 20B, 2 30's, a 50, and a 50B that are ready to ship. I believe the current lead time with most other EV retailers is several weeks!

I also have listed several of the new flavors of Manzanita Micro Chargers. These include a PFC-40, PFC-40 with onboard ammeter (displays AC line amps), a PFC-40H (Hybrid unit that can run on AC or DC input), and PFC-40HM (Hybrid with the onboard ammeter). These chargers, with currently limited specs and information, can be found here:


The PFC-40 is Manzanita Micros best hot-weather charger. It really cranks out the amps!

With regards to the Cluster unit, documentation has been progressing well. I won't give a date that it will be available by, but expect it soon! The documentation consists of a user's manual with specs and operating instructions.

All of the machined parts have arrived. Assembly of 5 beta units will begin shortly. If you are interested in a beta unit, contact me. They will be sold at a discounted price in trade for the quirks and bugs that are sure to occur. Production units will be available once those bugs and quirks are worked out. I'm expecting that will be sometime in April or May.

Here's a recent picture. The only thing missing from the pictured unit are the labels. They should be arriving within days.

If you have any questions about the Cluster unit, please let me know - I'd be happy to entertain them.

December 16, 2006

I'm pleased to announce the addition of the Bohm Stirling engine models to the Top-Line Shop. They can be found here:


While not completely coinciding with the current EV Source product line, they do represent a truly efficient engine design. For a very good summary on Stirling Engines, see this page:


Items purchased by about mid next week should arrive before Christmas.

On another note, the software development on the Cluster charger has been coming along nicely. A separate Windows application has been written to facilitate viewing each battery's data.

Documentation is still in the works! Please let me know if you have any specific questions.

November 25, 2006

Testing has been going well on the Cluster charger system. I finally snapped some images - here's a view with the cover removed revealing the guts (click on the image for a larger view):

You can see a PFC-20 at the top of the picture. The Cluster has a regbus connection which allows it to play together with the PFC chargers. Once the PFC has done the bulk of the charger - i.e. until the first battery reaches a determined point (e.g. 14.2V), the Cluster throttles the PFC back to allow the Cluster to top off each battery. As I said in the last few entries, user documentation will be published soon to list all the available features and specifications.

November 11, 2006

The Cluster PCBs arrived just after my last post. They've been tested, and are functioning correctly. Unfortunately, I'm having to push back my initial sales availability date of December 2006 to hopefully mid-January 2007. This is due to some longer-than-anticipated lead times on several of the machined parts.

I'm also behind on the user documentation (it has been started though). I had hoped to have it available for consumption by the end of October. My revised goal is the end of November. The release of the documentation will accompany the addition of the product listing on the website. This will also include pricing information, as well as pictures.

One new product was added this month. The Albright SW202A reversing contactor is now available on this page:


The SW202A comes with magnetic blowouts and microswitches.

The addition of a couple other new products is in the works. I'll be sure to post updated information on these possible products in my next post.

One final note. A month ago, I mentioned the addition of the Bohm Stirling engines. This is still going to happen. It has just been delayed by other priorities.

October 11, 2006

Just a quick update on things. The Cluster system is moving full steam ahead. The circuit board was ordered today. It should arrive for testing mid next-week. I'm still optimistic that it will be in customers' hands by about mid-December.

The user documentation will begin to appear about the end of this month. It will contain the Cluster's specifications, as well as pictures and operating instructions.

One final note. I will be carrying a new product. In general research of alternatives to the internal combustion, I came across the Stirling engine. It's a fascinating concept. A German company named "Bohm Stirling" produces miniature Stirling engines that operate on a small alcohol burner and rotate at 2-3 thousand RPM! Various models will be available under the category "Fun". Watch for these in the next week or two.

August 31, 2006

It's been awhile since I posted! I've been busy with the "Cluster" charging system (that's what it's been officially dubbed - "Cluster"). I'm still shooting for it to be ready for limited production in December of this year.

The summer special with free or reduced shipping on all orders over $500 will end on Labor day. Get your order in now for a really great deal on shipping.

A few items have been added to the Top-Line Shop. The SB-50 Anderson connector (on the Anderson connectors page). Also, I've changed reservoirs for the liquid cooling kit. The new reservoir shows indication that it will last better in the harsh under-hood environment. I'll have the reservoir for sale on the Liquid Cooling page soon.

Finally, the Zilla controllers have a pretty bad lead time right now. CafeElectric won't say for sure, but it will likely be 2-3 months before new orders are available. A note about "new orders". CafeElectric is not actually taking orders right now, i.e. not for the "old" prices (at least on LV, 156V models). However, they have agreed to continue taking place-holder orders with no guarantee on current prices. Consequently, I have set up an option on the Zilla page (link removed 10/27/08 due to unavailability of controllers) of the Top-Line Shop, to take a deposit rather than the full payment. If you put down the deposit, you'll be put in line (first-come, first-serve). When the controller is ready to ship, you can use the "Remaining" link on the controller page to finish the payment.

Hopefully this will help ease the frustration of those wanting to purchase a controller, but getting told "no" by other retailers.

July 6, 2006

The Top-Line Shop has a new product - Anderson style connectors. Also, pricing has been updated on all cabling items. Due to the increase in copper prices, all copper items have had a price increase.

Heavy duty lugs are again available. They were unavailable for several months.

June 22, 2006

All the pictures from the 200sx conversion were finally posted on the 200sx conversion page. There is still a lot of work to do adding captions to all the photos. Expect that in the next two or three years! :)

Work is progressing on the modular charging/monitoring system. A fully operational beta unit should be in the testing phase by mid-August. Contact me for details on exactly what this unit will do.

June 1, 2006

Check out the new Summer Special! Free or reduced shipping on all orders over $500 to the lower 48 US states. Shipping to Hawaii and Alaska, as well as international orders, will be reduced by the shipping cost to the lower 48. This special applies to all products within the Top-Line Shop. Some lower-priced items in combination with other higher priced items may not properly calculate the free shipping. If you get charged shipping on an order over $500, you'll be refunded the amount charged. NetGain motors are reduced to $100 to a residential order and $75 to a business address. Shipping lately has been over $200 to residential addresses, so this still reflects a major discount.

May 31, 2006

Unfortunately, I can no longer get gloss blue radiators. The only available color is gloss black. On the bright side, there is a new 3-tier radiator available! This is for extreme cooling power! It will be available for sale on the liquid cooling page in the next few days.

A quick update on the charging system mentioned on the 8th of this month: progress is being made on the modular/bulk charger system. Emphasis has been placed on a stand-alone unit where all modular chargers are housed and air-cooled. More information will be posted as the project progresses throughout the summer. Expected sale date is by the end of 2006 - possibly earlier.

May 16, 2006

I'll excited to announce the new TransWarp 11 motor to the EV Source lineup of NetGain motors. This is one cool motor! It is specifically designed for direct drive installation. Here's a picture:

(Click on the image for a full-size view)

The motor will be in the Top-Line Shop within the next few weeks. It has the following special features:

  • Enhanced drive end bearing
  • Automotive splined shaft
  • Turbo 400 shorty shaft housing
  • Slip yoke assembly available

Make sure to e-mail if you have any questions about this motor.

May 8, 2006

I have been looking in to adding a line of modular 12V chargers. Keep an eye out for the complete line of Soneil chargers. They should be available for sale in the next month or two.

Within the next several months, expect to see a modular/bulk charging/monitoring system available for sale. Modular chargers will work together with a bulk charger. The bulk charger (such as the Manzanita Micro PFC chargers) will charge until any battery reaches 14.4V. At that point, the bulk charger will be turned off, and the modular chargers will finish charging each battery.

Check back frequently for more information on this system.

April 17, 2006

The EV Source homepage is getting a new look! Keep an eye out to see changes that make the site easier to navigate and more attractive.

March 30, 2006

The EV Source tool rental/purchase for building cables is now online! There, you can order any or all of the tools necessary to make high quality cables. Another announcement regarding cable-making: we have partnered with our cable and cable accessories supplier to bring *free* professional cable manufacturing! All you have to do is purchase the materials and provide the specifications. The manufactured cables will be shipped completely fabricated. In the near future, a page will be available on our website to facilitate the ordering process for these custom cables.

March 20, 2006

The options for WarP motors have been simplified. All of the motors now come with advanced timing. Also, the option to have no tailshaft has been removed. If you have any custom requests that aren't displayed as an option, they might still be possible. Send an e-mail if you have any questions.

March 11, 2006

Another new product - 3/16" diameter heat shrink tubing in both red and black. It can be purchased in increments of 4", 1 foot, or 4 feet from the heat shrink tubing page.

March 7, 2006

The 6V PowerCheq units have been added as a regular product. They can be found on the PowerCheq sales page. The price is the same as the 12V model.

Lead times on the MK3 regulators is about 8 weeks - that puts their availability sometime at the end of April (and keeping the fingers crossed for that!). I should hopefully be receiving my beta units within the next month.

Keep up those great EV conversions everyone!

February 25, 2006

A new EV Source service is in the works - rental of tools to make cables. Most EV projects are done on a tight budget leaving little room for filling a tool chest with specialty tools. This will provide a way for EV converters to use a good set of tools for cable making. Available tools will include hex-crimpers, heat gun, cable shears, sheathing strippers, and a hammer crimper.

The service is not posted on the website yet, but will be up in the next few weeks. It will work very similar to tool rental at many of the auto parts stores. You'll buy the tools at their cost and they'll be shipped to you. Once you've finished the project, return the tools in good condition for a full refund. The only end cost will be the shipping to and from EV Source.

Let me know if you have any comments or suggestions on this service, or if you need to get the tools before they are posted on the website.

One last note. Our supplier of lugs is having trouble getting the heavy lugs. This is what most prefer to use for making cables, however, the normal lugs make great high-quality cables as well. I hope that the stock issue will be resolved soon - I'll be sure to post when they are available again.

February 20, 2006

Pictures of the MK3 regs are now displayed on the MK3 reg page!

February 18, 2006

This week's news can be summed up in a few bulleted points:

  • The new bracket for the D4 pump arrived, and I think it's the way to go. It has a more secure mounting point than the previous one.
  • A few additional items were added to the clearance section. Check this page regularly for low priced new and used components.

I've heard of several EV projects making progress. One is a high school in North Carolina that will be competing in an EV challenge. I've had an order from another eastern school, but I'm not sure if is competing in the same competition. It's wonderful to see youth getting involved in electric vehicle projects!

February 11, 2006

I received some input from a customer about the new mounting bracket for the D4 pump. The bracket only has one mounting tab. For most installations, this should be sufficient as the tubing will help stabilize and support the mounting bracket. But I'm looking into another variation of the bracket that would mount more securely. I hope to be able to report on it next week.

You can see the bracket in the newly updated photos of the cooling kit. One of these pictures can be seen here.

February 04, 2006

I've decided to start this blog to give a weekly update of the happenings here at EV Source. I'll be using this page to list new or upcoming specials, new products, and anything else that would be useful for EV Source customers to know.

This week, the cooling kit was once again updated. The Laing D4 pump has replaced the Bosch pump. The main motivator for this switch was the ability to put 3/8" connectors on the D4 - i.e. no need for reducer fittings anymore! The other big motivator was the results of Rich Rudman's testing of the Bosch unit. It was found to output sufficient for Zillas, but insufficient for the PFC-40L. The D4 should provide plenty of output for the 40L.

Also, the mounting brackets for the D4 showed up. In my opinion, it is the *perfect* mounting bracket for the D4! I'm looking forward to hearing users' opinions on how it works out in various installations.
