The control unit 10 includes battery currents Ib1 to Ibn, battery voltages Vb1 to Vbn,
Based on the battery temperatures Tb1 to Tbn, the battery 6 as shown in FIG.
The charging rate (the ratio when the upper limit voltage is 100% and the lower limit voltage is 0%) SOC and the error information ERR indicating the presence / absence of an abnormality are created.
SOC≈ ((battery voltage−lower limit voltage) / (upper limit voltage−lower limit voltage))
× 100 (%) (Equation 1)
The control unit 10 outputs charge / discharge control signals Sb1 to Sbn for ON / OFF control of the semiconductor switch elements 631 to 63n and 651 to 65n based on the charging rate SOC and the error information ERR.
Further, the control unit 10 controls the motor currents Iu, Iv, Iw and the smoothing capacitor voltage Ec.
P for driving the inverter device 4 based on f and the motor rotation frequency Frm
The WM pulse signal Sgi is output.
Further, the control unit 10 performs PWM for driving the converter device 3 based on the converter output current Is, the smoothing capacitor voltage Ecf, and the generator rotational frequency Frg.
The pulse signal Sgc is output.
The control unit 10 controls the semiconductor switch element so that the charging rate SOC of the normal battery is always within the hatched portion in FIG. Here, the maximum charging rate SOCmax is a state in which the battery is sufficiently charged, and indicates the illustrated charging limit. Further, the minimum charge rate SOCmin is a state in which the battery is fully discharged, and indicates the illustrated discharge limit.
For example, in the low speed range where the motor rotation frequency Frm is near 0, the remaining power is ensured from the hatched lower limit value to the discharge limit as shown by the arrow 1 (circle) in order to secure powering energy rather than absorbing regenerative energy. The motor rotation frequency Frm is Frm2.
Since the above high-speed region absorbs regenerative energy rather than securing powering energy, as shown by the arrow 4 (circle), the remaining charge capacity from the hatched portion upper limit value to the charge limit is secured. Further, when the motor rotation frequency Frm is in the middle speed range of Frm1, an arrow 2 (circle)
And the remaining charge capacity indicated by the arrow 3 (circle) are ensured in a well-balanced manner according to the speed.
If the charging rate SOC of the battery exceeds the charging limit during the above control, the control unit 10 turns off the semiconductor switching element that blocks the charging current of the unit including the corresponding battery. The discharge control signals Sb1 to Sbn are output, and the regenerative energy output from the inverter device 4 during the regenerative operation is controlled to be absorbed by the engine 1, the generator 2, and the converter device 3.
Conversely, when the battery charge rate SOC exceeds the discharge limit, the control unit 10
A semiconductor switch element that prevents the discharge current of the unit including the corresponding battery is O
The charge / discharge control signals Sb <b> 1 to Sbn that perform FF are output, and control is performed to increase the output of the converter device 3 in order to compensate for the power shortage during the power running operation.
Further, when the control unit 10 detects a battery abnormality based on the error information ERR,
The charge / discharge control signals Sb1 to Sbn that turn off all the semiconductor switch elements of the corresponding unit are output to disconnect the unit, and the engine 1, the generator 2, and the converter device 3 are controlled to compensate for the insufficient power.
