4x4 electric car conversions

Wilde EVolutions 71 Land Rover 4x4 Conversion

My dream is to convert an old Series Land Rover to an electric vehicle, but wondered about conversions for 4 wheel drive vehicles. It only makes sense that a heavier vehicle would burn through the charge quicker, as would running two additional wheels, but has it been done?

Hi, Jeremy!
Certainly, it's been done.
Above is a picture of Rod Wilde's Land Rover, with the 4x4 drive train it was born with, now fully electric.

He used an Advanced DC motor, 144v system, and 12 volt AGM batteries. As to the part about burning through the charge quicker with a heavy're right, of course. I'd consider using 6 volt batteries in this vehicle rather than the 12 volt (same number of volts total, but twice as many batteries) for better charge conservation and more cycle lives.

Note on keepin' it warm in Alaska: There's a company in Canada called REV Consultants Ltd that specializes in cold-weather electric cars. You can contact them from their website, and I interviewed Richard Lane from REV on the topic of winterizing our electric cars - you might be able to use that, too; )

Update 2011: LiFePO4 batteries are coming down in price, they're as cheap as lead per mile. You might find you like them better than lead for a 4x4 off-road application.

Good luck!

Have couple thoughts regarding 4WD EV
1. Battery size (range) will vary with vehicle weight. There will be a little more battery needed to overcome the front axle spinning (unless you have disconnect hubs)
2. Chucking engine transmission transfer case and driving front shaft with one motor and rear shaft with another AND use two controllers (one possibly slaved from other) would give you an ideal (almost - IDEAL is 4 motors one on each hub) AWD setup. This also gives you a limp home ability ie one motor or controller fails turn it off and use other.
3. In my experience AWD is needed only at 25 MPH or less and off road or in snow ice only.
4. Over 25 or so and on hard pavement and with front axle hubs disconnected you should do about as well as a truck of comparable weight.
