Rechargeable battery utilization controlling method for engine of car, involves determining value equal to correction to be applied to setpoint voltage value to define next setpoint voltage value, based on average current measurement value

摘要

The method involves comparing a first value (sigma u) representing a difference between a measured average voltage value (Vu) of a battery and a setpoint voltage value (Uc), and a second value (sigma i) representing an amplitude of variations of current measurement (Im) relative to a measured average current measurement value (Vi), respectively with two threshold values (S1, S2). A third value (DELTA U) equal to a correction to be applied to the setpoint voltage value to define a next setpoint voltage value is determined based on the average current measurement value. An independent claim is also included for a device for controlling utilization of a battery of a machine provided with an alternator, comprising calculation units.
