Geely is presenting a battery solution aimed at reducing the long-term wear associated with ultra-high-power charging. The development is intended to support charging rates of up to one megawatt while slowing the degradation that can affect battery capacity and performance over time.
Megawatt charging — equivalent to 1,000 kilowatts — places exceptional demands on an electric vehicle's battery system. High charging power can increase thermal and electrochemical stress, making battery durability as critical as charging speed for manufacturers pursuing shorter charging stops.
According to InsideEVs' report on Geely's battery development, the automaker's new approach is focused specifically on mitigating this degradation challenge. The available information does not set out detailed technical specifications for the solution.
The claim matters beyond headline charging times. For private EV owners, fleets and vehicle manufacturers, a battery that retains its condition under repeated high-power charging could help make ultra-fast charging more practical without imposing an outsized penalty on usable battery life.
Geely's work also highlights the next stage of EV charging competition. As charging hardware moves toward higher output, battery chemistry, pack design and thermal control will determine whether those peak figures can be used repeatedly in real-world service.
