Chinese electric car vendor BYD announced new battery technology that lets it charge HAN EV cars with 400 km of range in just 5 minutes.

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).

The EV giant, known for upending cost and operating norms in the industry, aims to build more than 4,000 ultra-fast charging units to make the technology available across China. BYD is reported to be considering Western Europe for a third plant because it wants to build brand recognition and acceptance as a local manufacturer.
