- the supply current value IB supplied to the power storage device 14 via the AC / DC converter 15 is changed to the charging current value IC calculated in S23 instead of the generated current value IG calculated in S24.
- the AC / DC conversion unit 15 performs the AC / DC conversion process so as to reduce the power utilization rate and supply the limited current (S26).

- the deterioration tolerance can be set in advance according to the specifications of the power storage device 14.
- the state of deterioration changes depending on the environmental temperature of the power storage device 14. That is, as shown in FIG. 5, as the temperature becomes lower, the deterioration allowable threshold moves to the small current side. Further, the degree of deterioration increases as the frequency of charging / discharging increases. Therefore, in order to keep the degradation degree of the power storage device 14 small, it is preferable that the temperature is not lowered, the charge / discharge current value is made small, and the charge / discharge frequency is reduced. That is, it is preferable to charge or discharge at a current value as low as possible, preferably a constant current value, avoiding rapid charge / discharge.
- FIG. 6 is a table summarizing the setting of the supply current value IB of FIG.
- the horizontal axis of FIGS. 6A and 6B is the SOC, and here, the target SOC is not shown as a single value, but as a range between the lower limit value and the upper limit value.
- the vertical axis of (b) is the supply current value IB to the power storage device 14.
- the power storage device 14 When the time t has elapsed from the start of braking, the power storage device 14 is charged with the supply current value IB, so that the SOC increases.
- the rotational speed N of the rotating electrical machine 13 decreases.
- the generated current value generated by the electromotive force e is proportional to the electromotive force e when the internal resistance is constant. Therefore, the generated current value also decreases as the rotational speed N decreases.
- IG calculated in S24 decreases as time t elapses from the start of braking, and the determination of S 25 is denied.
- the supply current value IB to the power storage device 14 becomes the total amount of IG due to S27, but IG becomes smaller as the time t from the start of braking elapses.
- the change in IG is indicated by a one-dot chain line in FIG.
- IB IG is set in S27, so that the supply current value IB to the power storage device 14 becomes gradually smaller. Since control is performed at a predetermined control interval, IB decreases step by step at each control interval. In FIG. 6B, in the SOC range close to the lower limit value of the target SOC, the supply current value IB gradually decreases from IC as shown by the broken line.
- the charging mode at a constant current value is preferable to the charging mode that changes stepwise.
- the supply current value IB indicated by the solid line is obtained by combining some of the step changes indicated by the broken line into one and the same current value. It is designed to be close to current charging. In this way, when the supply current value IB supplied to the power storage device 14 is within a predetermined threshold current difference between adjacent control intervals, the supply current value of the subsequent control interval is set to the supply current value of the previous control interval. By making it the same, the deterioration of the power storage device 14 can be reduced.
- the power storage device 14 is charged, and the SOC of the power storage device 14 increases.
- the determination in S21 is denied.
- the supply current value IB is narrowed down to a current value equal to or less than the allowable deterioration threshold value IBth and supplied to the power storage device 14.
- the SOC can be increased while avoiding deterioration due to overcharge or the like, and the range in which discharge control can be performed is expanded.
- the magnitude of the supply current value IB in the target SOC range is shown as being equal to or less than the allowable degradation threshold value IBth.
- the supply current value IB can be further reduced.
- the magnitude of the supply current value IB in the range exceeding the upper limit value of the target SOC is IB0 in FIG. IB0 is a current value at which deterioration hardly progresses.
- the configuration in which a desired supply current value for the power storage device 14 is obtained by PWM control of the AC / DC conversion unit 15 has been described.
- other configurations may be used as long as the current value is limited.
- the configuration may be such that the magnitude of the exciting current of the rotating electrical machine is controlled to control the magnitude of the generated power output from the rotating electrical machine, and the AC / DC converter 15 converts the AC generated power into the DC generated power as it is.
