Advanced thermal management in HV harness supports megawatt-scale fast charging

The management of thermal loads during high-current charging events remains a major technical challenge in e-mobility. While core drive system components such as inverters, electric motors, and high-voltage batteries are typically liquid-cooled, the high-voltage cables and charging harnesses connecting these systems have traditionally remained uncooled.
