Title
(EN) POWER CONTROL SYSTEM AND METHOD FOR FUEL CELL
(FR) SYSTÈME ET PROCÉDÉ DE COMMANDE DE PUISSANCE POUR PILE À COMBUSTIBLE
(ZH) 燃料电池的功率控制系统及方法
Abstract
(EN) The present application provides a power control system and method for a fuel cell. A main control unit is separately connected to a vehicle controller, an inverter control unit, each DC/DC control unit, and a high-voltage power distribution management unit, and generates a control instruction on the basis of the required power and a start/stop instruction that are sent by the vehicle controller. The inverter control unit controls an air compressor to output a required rotational speed. The high-voltage power distribution management unit controls a high-voltage BOP to power on and off. Multiple DC/DC control units are in parallel connection, and each DC/DC control unit receives a first high-voltage direct current, outputs a second high-voltage direct current and converges same into a second direct current filter circuit; after filtering is performed, same is connected to a vehicle drive system. On the basis of the required power and the start/stop instruction that are sent by the vehicle controller, the main control unit controls the inverter control unit, each DC/DC control unit, and the high-voltage power distribution management unit to perform corresponding operations without requiring the vehicle controller to separately control each unit and separately receive a state fed back by each unit, thereby reducing the complexity of control for the vehicle controller and reducing the burden of communication.
(FR) La présente invention concerne un système et un procédé de commande de puissance pour une pile à combustible. Une unité de commande principale est reliée séparément à un dispositif de commande de véhicule, une unité de commande d'onduleur, chaque unité de commande CC/CC et une unité de gestion de distribution d'énergie à haute tension et génère une instruction de commande sur la base de la puissance requise et d'une instruction de démarrage/d'arrêt qui sont envoyées par le dispositif de commande de véhicule. L'unité de commande d'onduleur commande un compresseur d'air pour la délivrance d'une vitesse de rotation requise. L'unité de gestion de distribution d'énergie à haute tension commande un bloc obturateur de puits à haute tension pour sa mise sous tension et hors tension. De multiples unités de commande CC/CC sont en connexion parallèle, et chaque unité de commande CC/CC reçoit un premier courant continu à haute tension, délivre un second courant continu à haute tension et amène ce dernier à converger dans un second circuit de filtre à courant continu ; après la mise en œuvre du filtrage, ce dernier est relié à un système d'entraînement de véhicule. Sur la base de la puissance requise et de l'instruction de démarrage/d'arrêt qui sont envoyées par le dispositif de commande de véhicule, l'unité de commande principale commande l'unité de commande d'onduleur, chaque unité de commande CC/CC et l'unité de gestion de distribution d'énergie à haute tension pour réaliser des opérations correspondantes sans nécessiter que le dispositif de commande de véhicule ne commande séparément chaque unité et ne reçoive séparément un état renvoyé par chaque unité, ce qui permet de réduire la complexité de commande pour le dispositif de commande de véhicule et de réduire la charge de communication.
(ZH) 本申请提供燃料电池的功率控制系统及方法,主控单元分别与车辆控制器、逆变器控制单元、每个DC/DC控制单元以及高压配电管理单元相连,基于车辆控制器发送的需求功率和启停指令生成控制指令;逆变器控制单元控制空压机输出需求转速;高压配电管理单元控制高压BOP上下电;多个DC/DC控制单元并联,每个DC/DC控制单元接收第一高压直流电和输出第二高压直流电,并汇流至第二直流滤波电路;其进行滤波后接至整车驱动系统。基于车辆控制器发送的需求功率和启停指令,主控单元控制逆变器控制单元、每个DC/DC控制单元和高压配电管理单元执行相应操作,无需车辆控制器单独控制各个单元和单独接收各个单元反馈的状态,实现降低车辆控制器控制复杂性和减轻通信负担目的。
