wenisman Posted December 1, 2021 Report Share Posted December 1, 2021 (edited) I was actually looking at doing the EV conversion on my ke26, as i was half way through rebuilding the engine and thinking of going efi... there are only 2 issues, the first is do i have $30k to do the EV conversion and the second is where to put the batteries. Easiest solution is to keep the gearbox and drive train and get an adapter plate and bolt the motor in place of the engine. I went and did the EV course online with EV Alliance and the rough ratio for a 1 tonne car is 20kwh will get you 100km of range... that is actually 4 tesla battery modules or about 7 LG Chem modules, this is about 70cm x 60cm x 30cm (and close to 160kg) when you add in the cooling plates and battery management modules and package it in a weatherproof box. Needless to say this is actually a large space that is much bigger than a fuel tank on a car. You also need to consider that you will need to engineer the solution and speaking to my local engineer you can go about 10-15% over the original weight of the car from the factory if you want to be able to register it for the road, so when you add in the weights of DC-DC converter (so you can run the 12v system on your car like lights, aircon etc), chargers, motor, Management modules, adapter plate for motor to gearbox etc you don't have a lot of wiggle room of you only take out an old 3k motor and gas tank. Also the original drive train wasnt designed to take the full torque that an electric motor can put out, so often people have to upgrade the gearbox or at least the internals, and the replace the axles. Whilst I am still looking into the best solution as throwing time and money into an EFI conversion on an old 3k motor is good, is there something that will keep the car running longer? Personally if i can get 200km of range in a battery package about the size of a gas tank then the EV conversion will become worth while, so whilst i have time i am keeping my options open Edited December 1, 2021 by wenisman Quote Link to comment Share on other sites More sharing options...
