Aging Wheels is doing a video series on this exact question. He converts a combustion engine Ford Escape to an EV using two 450HP Tesla motors.
I quite like his stuff. :)
450 HP ? Twice ?
That’s more than a (small) plane how does a car need that big engines ?
It probably doesn’t need that much power, but speed is fun and the extra torque can be useful.
The new Rimac Nevera (an EV hypercar) has over 1800 HP.
He is going to covert a bus to an electric rv. The escape is the test bed to test equipment first.
Remove the IC engine. Install an electric motor and all the necessary electronics: batteries, control circuitry, charging circuitry, etc.
You can find companies selling conversion kits for certain cars. For example, here’s one for a 1970’s VW Super Beetle.
If you are into bigger custom modifications, Chevrolet sells an eCrate engine kit. It’s basically the drivetrain and battery pack from the Chevy Bolt. You have to figure out how to package it in your car of choice. As a demonstration, they used it to convert a 1977 Chevy Blazer.
Edit: Note that removing the IC engine means you also lose heat, air conditioning, power brakes, and power steering. Those systems all rely on waste heat, belts, or vacuum lines from the IC engine. You need to replace them all with electric devices.
We’re expecting all the drivetrain components to hold up to instant torque?

I know people are used to it, but AC and power-steering are arguably luxuries you can do without. Especially if the car’s light.
The problem is people are also unwilling to uncompromise on range and want an arguably overpowered motor and acceleration, which necesitates a large battery. Large/heavy battery -> power steering + different suspension + better/more expensive brakes + different wheels + … + …
Chuck in a 30hp engine into a classic beetle, limit the range to 100km, and you need a far smaller (and less heavy) battery and it’ll likely be a far easier conversion that’ll likely still outperform an actual classic beetle.
If you want to turn a classic beetle into a tesla killer, with modern luxuries, it’s going to be heavy, difficult to make and expensive.
DIY EV kits are a thing, but a quick google shows some wildly varying prices. Probably depends on exactly what kind of car you are trying to refit and the performance you’re looking for.
There’s a company in my town that electrifies vintage European cars. I’m told that the bulk of the work is figuring out where to put the batteries and how to cool them.
Absolutely min things to swap Gonna need a battery of some kind 3 phase induction motor (probably) Motor speed controller Some sort of battery charger Big inverter for big motor An ecu-like thing to control everything Specifics about how to make this all work in a vehicle will depend wildly on which vehicle. Some basically can have these things bolted on, others require special assemblies to get the power to the wheels somehow.
An ev swap can be (relatively) cheap and simple or wildly expensive and difficult just depends on your goals.
Most of the parts I mentioned are available as off the shelf components and sometimes even as a swap kit.
