METHOD FOR CONTROLLING VOLTAGE OF FUELCELL IN STOP-MODE OF FUELCELL VEHICLE

摘要

A checking step of checking entry of the fuel cell stop mode into the control unit; A calculation step of calculating a bus voltage command value in a control unit based on the available charging power of the battery, which indicates the degree of power that can be charged in the high voltage battery when the fuel cell enters the stop mode; A voltage lowering step of controlling a converter connected between the high voltage battery and the bus terminal such that the voltage of the bus terminal is the bus terminal voltage command value in the control unit; And a power consumption step of increasing the power consumption of the vehicle electrical load at the control unit when the voltage of the fuel cell measured through the voltage sensor after the voltage lowering step is equal to or higher than a preset reference voltage in the memory, A voltage control method in mode is introduced.
