Method for manufacturing traction battery for e.g. electric vehicle, involves unloading first battery and charging second battery such that electrical energy from unloaded battery is partially supplied to loaded second battery

摘要

The method involves loading the batteries successively in a frame after they are unloaded. The first battery (12) is unloaded and second battery (16) is charged such that the electrical energy from the unloaded battery is partially supplied to the loaded second battery. An independent claim is included for apparatus for testing functionality of battery.
