POWER CONVERSION CONTROLLING METHOD OF FUEL CELL-BATTERY HYBRID-ELECTRIC VEHICLE AND CONTROL DEVICE

摘要

PURPOSE: A control method of power distribution and a control device of the fuel battery - battery hybrid system are provided to improve the energy distribution efficiency by appropriately distributing output ratio of the battery and fuel battery. CONSTITUTION: A value of mode conversion output is set in range less than the maximum output value of a motor supplied with constant voltage from the fuel battery and battery. The required output is printed out in real-time during the driving. The mode conversion output is compared with the required output. A fuel battery converter starts operating and stopping according to the comparison result. The fuel battery converter and the battery converter start operating at the same time in order to obtain constant output according to the comparison result.
