<P>PROBLEM TO BE SOLVED: To charge and discharge a storage battery reliably if the true deterioration state of the storage battery does not agree with the deterioration state recorded by a data processing device which manages the battery, in a control method and a control unit which control a maximum permissible current at the time of charging and discharging of the storage battery for a hybrid vehicle and the like by the state of the storage battery reflecting the deterioration state of the battery. <P>SOLUTION: A state detection means of an electricity-storing means transmits a signal for limiting a permissible current to a current control means, if a state is detected that the operation result of the deterioration state stored by the state detection means itself does not agree with the true deterioration state of the electricity-storing means. The deterioration state of the electricity-storing means is calculated based on the data of the electricity-storing means charged or discharged by the limited current. When convergence is detected in the calculation result, a signal for releasing the limit of the permissible current is transmitted to the current control means, and the current control means in turn releases the limit of currents to/from the electricity-storing means to control permissible charging and discharging currents. <P>COPYRIGHT: (C)2009,JPO&INPIT |
