The invention discloses a multi-voltage source enabling control method for a hydrogen energy automobile, and belongs to the technical field of hydrogen energy automobiles, and the hydrogen energy automobile comprises a hydrogen fuel cell system, a whole automobile driving system, a whole automobile high-voltage distribution system PDU, a whole automobile other electric appliance system, a DC/DC1 inverter, a DC/DC2 inverter, a first voltage source and a second voltage source. The first voltage source supplies power to the hydrogen fuel cell system, the second voltage source supplies power to other electric appliance systems of the whole vehicle, the hydrogen fuel cell system transmits voltage to the whole vehicle high-voltage distribution system PDU, and the whole vehicle high-voltage distribution system PDU supplies power to the whole vehicle driving system and the hydrogen fuel cell system. A hydrogen fuel cell system in the hydrogen energy automobile is separated from other electric appliance systems of the whole automobile, independent voltage sources are used for independently supplying power to the two systems for enabling, multiple voltage sources used by the hydrogen energy automobile controlled by multiple voltage source enabling reduce the coupling of the electric appliance systems of the whole automobile, the independence of all the systems is improved, and the reliability of the whole automobile is improved. Therefore, the defects of a single voltage source can be reduced or eliminated.
本发明公开了一种氢能源汽车多电压源使能控制方法,属于氢能源汽车技术领域,包括氢燃料电池系统、整车驱动系统、整车高压分配系统PDU、整车其余电器系统、DC/DC1逆变器、DC/DC2逆变器、电压源一以及电压源二;电压源一为氢燃料电池系统供电,电压源二为整车其余电器系统供电,氢燃料电池系统将电压传输至整车高压分配系统PDU,整车高压分配系统PDU向整车驱动系统、氢燃料电池系统供电。该发明将氢能源汽车中的氢燃料电池系统与整车其余电器系统区分开来,分别使用单独的电压源给这两个系统单独供电使能,多电压源使能控制的氢能源汽车使用的多电压源降低整车电器系统的耦合性、增加各系统的独立性,这样能减少或者杜绝单套电压源的缺陷。
