EV Transmission, or CVT?

by Jim D
(Lake Orion, Michigan)



Is a transmission required on EVs? If so would a CVT from a snowmobile offer an advantage?

Hi, Jim -

No, you don't actually need a transmission for an EV. Usually, however, this means using a larger motor and controller, which costs money and weight.

CVTs, continually variable transmissions, offer a perhaps cost effective alternative to the beefier motor and controller usually required in the transmission-less conversion. Read this excellent discussion in the EVDL for Lee Hart's breakdown on electric car transmissions and CVTs.

CVTs seem to be a popular alternative to the controller on small EVs!

Best of luck with your project, and keep us posted!

Regards,
Lynne
