Don t Convert It. Electrify It!

Why remove the ICE engine for a BEV conversion when you can instead just add batteries, a motor, and controller and electrify it! The finished vehicle could have no limit in range, and be able to run routine short trips (15 miles) 100% electric from a small battery pack without using any gasoline. The electric top speed could be set to 45-50 mph requiring a small electric motor (for a light vehicle).

The cost for components and labor could be very inexpensive. All of the components could be bolt on and removable. All of the stock ICE vehicle systems would remain fully functional, i.e. the engine can be left idling for cabin heating and air conditioning and to provide 12v power for all of the 12v accessories. As an option, a DC-DC converter could be used to not have to run the engine for 12v power.

An etek RT/Perm PM motor could be used to allow for regen, but it may need to be forced air cooled, and this is only recommended for a light vehicle. It will probably need to be overvolted to 96v as well (I don’t know if this is a good idea yet). A 6.7 inch series motor would also be a good compact and light option.

The electrification process would be very easy to do. A small PM motor and direct chain drive to the drive axle could be used. The batteries could be set in the cargo space with a plasctic cover on top of them so cargo can be placed on top.

Very limited wiring would need to be done.


Here’s what I’m thinking of doing for a Suzuki Sidekick (with associated costs):

Etek-RT: $525

Kelly controller w/regen for up to 120v: $800

Eight BB EB50-12 batteries $1000?

Vector 12v 40 amp charger: $100

#50 Chain, sprockets w/custom machining of part to drive axle: $100

Anderson connectors to do series/parallel switching for driving/charging: $100

Wire, Lugs, and fuse: $100

PRINDIVILLE Electric Hummer – Lead-acid battery 72V drive system

Red button type Albright disconnect: $125

Pedal throttle control: $100

Blower to forced-air cool the motor: $30

Plastic cover for batteries: $15

Material for motor mount: $20

So that’s $3765 for the electrification. It’ll be able to run for about 12 miles off electric which is more than adequate for my daily needs, especially with being able to charge at work. If I need to drive further, then I’ll use the ICE when needed.

I can easily remove and sell all of the components if need be, and recover most of the cost. I’ll have a fully functional gas vehicle with or without the electrification stuff. The electrification will be so much easier than doing a conversion, and I’ll have a much more useful vehicle than what a conversion would offer.

I would never need to give a 2nd thought to range.
