Abstract: A method for open-loop and closed-loop control of a rechargeable battery having at least one energy storage cell, at least one temperature sensor for detecting at least one temperature value of the rechargeable battery, a current measuring device, a voltage measuring device and also a rechargeable battery control device having at least one rechargeable battery storage device. The method involves the method steps of setting a first charging current value for charging the rechargeable battery; charging the rechargeable battery with the first charging current value until a first temperature value is reached; setting a second charging current value for charging the rechargeable battery for maintaining the first temperature value for a first predetermined time duration; setting a third charging current value for charging the rechargeable battery after a second predetermined time duration has elapsed; and setting a first voltage value after the second predetermined time duration has elapsed. Rechargeable battery and charger for carrying out the method.
