Electric vehicles (EVs) still require an external power source to recharge their batteries, and there are several reasons why EVs cannot charge themselves:
Electric vehicles cannot generate all the energy required to charge their batteries, unlike gasoline-powered vehicles that generate energy from the burning of fuel.
The battery technology that powers EVs has not yet advanced to the point where it can efficiently self-charge the vehicle while it is in motion.
The laws of physics create a fundamental barrier to self-charging EVs since energy cannot be created from nothing.
Developing self-charging EVs and the infrastructure to support them is expensive and not financially viable yet on a mass scale.
Regenerative braking technology captures energy that would otherwise be lost during braking to recharge the vehicle's batteries.
