There are currently four main types of EVs: Battery electric vehicles (BEVs): fully-electric, meaning they are solely powered by electricity and do not have a petrol, diesel or LPG engine, fuel tank or exhaust pipe. BEVs are also known as ''plug-in'' EVs as they use an external electrical charging outlet to charge the battery.
The share of total passenger kilometers driven goes electric faster than the fleet due to the high utilization of vehicles in shared applications switching to electric faster than private vehicles. The increase in the EV travel distance implies a faster return of the economic investment as well as in improved environmental benefit, as the main …
