CONTROL DEVICE FOR POWER SUPPLY CIRCUIT

WIPO Patent Application WO/2011/145447

A1

Provided is a control device for a power supply circuit in which a plurality of high-voltage battery packs are provided, wherein if any one safety switch is off, the startup state of a high-voltage circuit is totally prevented, even when a careless mistake such as a careless power-on operation is made, the circuit is prevented from being started, and also the overall power supply is cut off by turning off one safety switch, thereby improving the convenience of work. A voltage detection means (9-1~9-n) for detecting the internal voltage is provided in a battery pack (4-1~4-n), and by detecting the voltage change based on the operation of one or more safety switches (8-1~8-n), all relays (5-1~5-n) of a plurality of battery packs (4-1~4-n) provided in parallel are maintained in an open state.
