摘要： PROBLEM TO BE SOLVED: To provide a vehicular power source system in which a generator and a first storage battery are connected with a second storage battery via a connection switch, the vehicular power source system restraining the operation of an electrical load from becoming unstable when the a connection switch is cut off.SOLUTION: The vehicular power source system includes an alternator 10, a lead storage battery 20, a lithium ion storage battery 30, a MOS switch 50, and an ECU 80. An electrical load 42 is connected to the lead storage battery 20. The ECU 80 exerts control such that an adjustment voltage of the alternator 10 is higher than the output voltage at non-regenerative power generation when regenerative power generation is in progress. In addition, the ECU 80 cuts off the MOS switch 50 when the output voltage (Pb) of the lead storage battery 20 lowers to the cut-off voltage after the regenerative power generation ended. Further, when regenerative power generation is in progress, the ECU 80 sets a target voltage of the lead storage battery 20 and exerts control such that the deviation of a detected value from the target voltage is held equal to or less than a predetermined value and the adjustment voltage does not exceed the target voltage by a predetermined voltage range or more.

摘要： PROBLEM TO BE SOLVED: To provide a battery system controller capable of suppressing the raising amount of the terminal voltage in a lead accumulator when the lead accumulator and a high performance storage battery which are electrically connected to each other via an open-close switch, are cut off.SOLUTION: A battery controller is applied to a battery system having an alternator 10, electric loads 42, 43, a lead accumulator 20 capable of charging power generated by the alternator 10, a lithium battery 30 capable of charging power generated by the alternator 10 and discharge power of the lead accumulator 20, and a MOS switch 50 for switching electrical conduction or cut-off between the alternator 10, and the lead accumulator 20 and the lithium battery 30, and in which a terminal voltage of the lithium battery 30 is controlled to be lower than that of the lead accumulator 20. The switching from electrical conduction to cut-off of the MOS switch 50 is permitted on the condition that a charging current flowing into the lithium battery 30 is smaller than a decision value, and the decision is set at a smaller value as the internal resistance of the lead accumulator 20 is larger.
