Abstract

TASK] IN A POWER STORAGE UNIT WHEREIN ELECTRIC POWER SUPPLY TO AN ELECTRIC VEHICLE AND ABSORPTION OF REGENERATED ELECTRIC POWER ARE PERFORMED BY CHARGING/DISCHARGING AN ELECTRIC DOUBLE-LAYER CAPACITOR BY A STEP UP/DOWN CHOPPER, MEASURES ARE PROVIDED BY WHICH A LOAD RESISTOR FACILITY IS NOT REQUIRED AND PREVENTION OF INVALIDATED REGENERATION OF THE ELECTRIC VEHICLE AND PROTECTION OF THE ELECTRIC DOUBLE-LAYER CAPACITOR FROM OVER VOLTAGE ARE ACHIEVED WITHOUT INCREASING A CAPACITY OF THE CAPACITOR. [MEANS FOR SOLUTION] THE ELECTRIC VEHICLE 2 IS OF A TYPE THAT HAS SUCH A FUNCTION AS TO REDUCE A REGENERATIVE CURRENT FROM 100% TO 0% IN ACCORDANCE WITH A PANTOGRAPH POINT VOLTAGE THAT IS ABOVE A SPECIFIED LEVEL. WHEN THE ELECTRIC DOUBLE-LAYER CAPACITOR 4A IS CHARGED UP TO AN ARBITRARY VOLTAGE, A CONTROL SECTION 4C OF THE STEP UP/DOWN CHOPPER 48 CARRIES OUT AN INVALIDATED REGENERATION PREVENTION CONTROL BY WHICH THE VOLTAGE OF A FEEDER CABLE IS INCREASED UP TO SUCH A LEVEL AS TO ACTUATE THE REGENERATIVE CURRENT REDUCING CONTROL FUNCTION OF THE ELECTRIC VEHICLE 2.
