China's BYD has unveiled a megawatt charging system that it says can charge an EV as quickly as filling up a fuel tank, and said it will build a network across China, igniting a new super charging race.

Central to the Han L’s fast charging is its internal electrical infrastructure. It starts with the battery, which according to CarNewsChina citing regulatory documents, is an 83.2 kWh lithium-iron-phosphate (LFP) pack that operates at 945 volts. (In its marketing materials, the company appears to have rounded up and lists it at 1,000 volts).
