Battery charging method for motor vehicle, involves charging battery by fuel cell when charging level is less than/equal to lower charging level, and stopping charging when charging level is greater than/equal to upper charging level

摘要

The method involves measuring a charging level (N) of a battery (12), and comparing the level (N) with a lower charging level (Ni) and an upper charging level (Ns). The level (N) is measured as long as the level (N) is greater than the level (Ni). The battery is charged by a fuel cell (2) when the level (N) is less than or equal to the level (Ni). The charging is stopped when the level (N) is greater than or equal to the level (Ns). An independent claim is also included for an electric charging device for battery of motor vehicle.
