POWER CONTROL DEVICE OF HYBRID SERVICE CAR

摘要

PROBLEM TO BE SOLVED: To improve assemblability and maintainability of hybrid type apparatuses and facilitate common use of a general model and a hybrid model.SOLUTION: A power control device of a hybrid service car includes: an engine 8 which outputs power; a secondary battery unit 46 which outputs high-voltage power; a voltage converter B which converts the high-voltage power from the secondary battery unit 46 to lower-voltage power; an inverter 49 which converts direct current power from the secondary battery unit 46 into alternating current power; an AC motor C which is operated by the alternating current power from the inverter 49; a first control unit 21 for controlling the engine 8; a second control unit 52 for controlling the motor; and a third control unit 53 which integrally controls the engine 8 and the AC motor C on the basis of output information of the first control unit 21 and the second control unit 52. The voltage converter B, the second control unit 52, and the third control unit 53 are disposed at a predetermined area of a vehicle body in a concentrated manner.
