Battery performance is still a limiting factor to the widespread adoption of EVs by the buying public, with range anxiety rightly or wrongly an issue. This applies whether one is building an EV Super Mini or a sportscar such as the Porsche Taycan. The manufacturer of the latter has recently released a summary of its view of the current battery market, drawing on input from both its engineers and experts from third party institutions.

According to Porsche, the reality is that currently, batteries are still a compromise. “For Porsche in particular, high charging performance plays a major role,” says Dr Stefanie Edelberg, engineer at Porsche Engineering. “Sporty driving drains the battery faster, and the customer doesn’t want to have to wait an hour to fully recharge it.”
