Method for controlling control voltage of alternator equipped in car, involves simultaneously controlling control voltage of alternator and battery voltage applied to battery, irrespective of incoming or outgoing current of battery

摘要

The method involves simultaneously controlling a control voltage (SENSE) of an alternator (3) and a battery voltage (VBatt) applied to a battery (2) e.g. lithium-ion battery, irrespective of incoming or outgoing current (iBatt) of the battery. The control voltage is controlled based on a voltage setpoint and a current setpoint issued by a controller of a servo device (7), where the servo device includes a current-voltage adapter (10), a voltage-voltage adapter (12), an adder (9), a proportional integral corrector (PI), and a transimpedance amplifier (B). An independent claim is also included for a servo system.
