Fast charging is heating up.
DC fast charging relies on higher power — over 350kW or more in Extreme Fast Chargers (XFCs). That kind of power generates significant heat. As external converters and EV supply equipment controls are responsible for safely and effectively managing the higher power levels between the charger and an EV, they require effective thermal management.
And this poses another challenge. A DC fast charger necessitates larger conductors. Along with increased charging speed and higher heat, the resulting cables can become bulky and unwieldy.
