I've never seen an electric car that used a CVT, normally they are just direct drive. Like the motor spins a reduction gearbox, which is directly connected to the wheels. There is only one gear, not even a reverse, the motor just spins backwards to move the car backwards.
That is also why smaller electric cars typically top out around 80-120mph, and you need a very powerful one to go 150+ like a Tesla.
The issue is that at low speed the motor has to spin very slowly which requires immense torque. This is generally overcome with a reduction ratio. The less reduction the faster you can go, but if your motor is not powerful enough then you won't have enough torque on the steepest hills etc.
Potato, potato.
