Electric cars also have impacts arising from the manufacturing of the vehicle.

Induction motors do not use magnets, but permanent magnet motors do.
The RBS is a key mechanism for electric vehicles to obtain braking energy. This technology seriously affects the economy, emissions, safety and other functions of electric vehicles. By improving the RBS, the kinetic energy recovery rate of the vehicle can be significantly increased, and the driving stability of the vehicle can be improved. [61]
Numerous plug-in electric vehicle (EV) fire incidents have taken place since the introduction of mass-production plug-in electric vehicles. [1] In some cases, an EV's battery (at least arguably) caused a fire. In other cases, an EV's battery did not cause a fire, but it added "fuel" to a fire.
