China is back with another engineering marvel. This time, in the form of BYD’s new battery system which is reportedly capable of charging an electric car in just five minutes – roughly the same amount of time as refueling a combustion vehicle.

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).
