The real objective in developing electric vehicles (EVs) is to offer models with positive characteristics that encourage people to actually buy them. Higher efficiency and greater power density are your key design goals. However, as an EV designer, you must also address the weaknesses and limitations that discourage the purchase of an EV.
The number one and number two consumer issues are “range anxiety” and excessive charging time. Consumers aren’t happy with short-range limitations that will force them to constantly worry about dying batteries and finding that rare nearby charging station.
