Abstract: A battery system includes a chargeable and dischargeable secondary battery and a controller that estimates the deterioration state or the charge state of the secondary battery. When estimating the deterioration state or the charge state, the controller uses an average ion concentration between a positive electrode and a negative electrode.

The average ion concentration between the electrodes can be calculated with a computing expression that includes a surface pressure of the secondary battery as a variable. The surface pressure of the secondary battery can be detected by a pressure sensor. The surface pressure of the secondary battery can also be estimated from an electric current flowing through the secondary battery.

The circuit has a series circuit of first and second power transistors with respective parallel-connected diodes connected between the potentials of a supply voltage source. The node between the power transistors is connected via a coil to the capacitive actuator. For charging the actuator, the first power transistor, which connects the capacitive actuator to the positive potential, is periodically turned on during a prescribed time and turned off when a first prescribed threshold value is reached by the current through the actuator, until a lower threshold value is reached by the current. If the actuator current no longer reaches the first prescribed threshold value then the first power transistor is turned off after a time that corresponds to the maximum value reached by the actuator current.
