In vehicle storage battery (1) there are cells (3), a controllable switch (5) connected between inner cells and a processor (7), which controls the function of the switch (5) and communicates with a processor (35) in the charging regulator (33). The processor (7) continuously calculates the remaining capacity in the battery, based on up-to-date parameters such as current through the battery, open circuit voltage of the battery, the battery temperature and an initial value obtained during the heavy discharge of the battery when energizing the starter motor (25). If the capacity decreases, the current supply to not necessary devices (75-79) can be turned off. When the engine (23) is not running, all current supply can be stopped for ensuring that there will always be sufficient capacity for running the starter motor (25) for starting the engine (23). Further, the processor (7) monitors the charging of the battery (1) from the generator (21) and commandes a processor (33) in the charging regulator to set an exciting current in a field coil (41), so that a suitable generator voltage is achieved. |
