First off, what is it, how does it work?
wikipedia quickstop:
A battery electric vehicle (BEV) is an electric vehicle that utilizes chemical energy stored in rechargeable battery packs. Electric vehicles use electric motors instead of, or in addition to, internal combustion engines (ICEs). Vehicles using both, electric motors and ICEs, are examples of hybrid vehicles, and are usually not considered pure BEVs. Hybrid vehicles with batteries that can be charged and used without their ICE are called plug-in hybrid electric vehicles, and are pure BEVs while they are not burning fuel. BEVs are usually automobiles, light trucks, motorized bicycles, electric scooters, golf carts, forklifts and similar vehicles, because batteries are less appropriate for larger long-range applications.
BEVs were among the earliest automobiles, and are more energy-efficient than all internal combustion vehicles. BEVs produce no exhaust fumes, and minimal pollution if charged from most forms of renewable energy. Many are capable of acceleration exceeding that of conventional gasoline powered vehicles. BEVs reduce dependence on petroleum, mitigate global warming by alleviating the greenhouse effect, are quieter than internal combustion vehicles, and do not produce noxious fumes.
Ongoing battery technology advancements have addressed many problems with high costs, limited travel distance between battery recharging, charging time, and battery lifespan. Those drawbacks have historically been blamed for the limited adoption of the BEV. Toyota, Honda, Ford and General Motors all produced BEVs in the 90s, but only because they were forced to do so by California Air Resources Board’s Zero Emission Vehicle Mandate. The major US automobile manufacturers have been accused of deliberately sabotaging their electric vehicle production efforts.[1][2] A handful of future production models have been announced, although many more have been prototyped.

One is roots.
