Title:
AIR CONDITIONER FOR ELECTRIC MOTOR VEHICLE
Document Type and Number:
Japanese Patent JP3166453
Kind Code:
B2
Abstract:

PURPOSE: To eliminate the application of an abnormally high voltage by stopping a charger when a battery voltage is higher than a predetermined value, and sequentially non-operating a motor-driven compressor driver and a switching unit during operating of the driver.
CONSTITUTION: The voltage of a battery 2 is detected by a battery voltage detector 7, and transmitted to a controller 6. When the voltage of the battery 2 is higher than a predetermined value, the controller 6 does not operate a charger 4, and stops the charger 4 when the charger 4 is operating. It stops a motor-driven compressor driver 1 during operating of the driver 1, and then opens a switching unit 3. If the voltage of the battery 2 is lower than the predetermined value during operating of the driver 1, the driver 1 is stopped, and then the unit 3 is opened. Accordingly, an abnormally high voltage is not applied, and rush current is not generated in a capacitor from a power supply.
