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.

Fellten Charge Qube

Peter Donaldson investigates a containerised system that can charge multiple vehicles and doesn’t need a grid connection. Until the electric power grid is able to support fast charging for EVs everywhere, there is likely to always be a market for something like Fellten’s Charge Qube – a containerised system that stores energy in repurposed battery packs and can charge multiple vehicles simultaneously, with or without a connection to the grid.
