US being left behind in EV charging speeds as China goes sub-5 min to 70%
Summary
Ars Technica analyzes the widening gap between US and Chinese EV charging speeds, highlighting Geely’s new battery capable of 2.2 MW charging that can push 10-70% in 4.5 minutes. The piece compares Chinese fast-charging progress with US infrastructure, noting BYD and CATL developments and the limits of current US chargers (generally 250 kW–600 kW). It also discusses megawatt charging for heavy-duty vehicles and the ongoing shift in hardware and grid expectations, while pointing to policy and standardization factors that influence adoption in the US.
