Abstract
A battery charging system and a method for a increasing endurance of a high voltage battery in a hybrid electric vehicle includes a high voltage battery for vehicle propulsion, a generator for charging the high voltage battery, a DC/DC converter for converting a high voltage to a low voltage, a low voltage battery charged with the low voltage, and an alternator, driven by an engine, and connected with the low voltage battery in parallel with the voltage converter. The method includes registering a parameter, where the parameter is at least one of a state of charge of said high voltage battery, and energy inflow/outflow to/from said high voltage battery to said vehicle drive motor or said generator, and controlling the low voltage in dependence of the registered parameter.
