There are three main kinds of electric vehicles: battery-electric (BEVs or EVs), plug-in hybrid electric (PHEVs) and hybrid electric (HEVs). Both BEVs and PHEVs need to be charged via special charging stations. HEVs use their onboard electric motor as a supplement to the existing internal combustion engine (ICE), and are charged via regenerative braking.
Because both BEVs and PHEVs require charging, you'll need to make some decisions about charging stations: where to install them, whether to install some at employees' homes, and how many you'll need.
It's well known that fully electric vehicles cost more upfront. But, what you may not realize is that over the lifespan of the vehicle, an EV could actually work out better for your bank balance, as well as better for the environment.
