Abstract: front page image
(EN)The present invention relates to a method and an apparatus for controlling the pump speed of a redox flow battery. According to one embodiment of the present invention, the method for controlling the pump speed of a redox flow battery for transferring an electrolyte stored in an electrolyte tank to a cell stack comprises the steps of: measuring the input power and/or the output power of the redox flow battery; measuring the charging power and/or the discharging power of the redox flow battery; calculating the power loss of the redox flow battery by using the difference between the input power and the charging power, and the difference between the output power and the discharging power; and adjusting the pump speed according to the power loss. According to the present invention, the power efficiency of the redox flow battery system can be maximized by controlling the pump speed and the supply amount of electrolyte according to the pump speed so as to minimize the power loss of the redox flow battery system.
(FR)La présente invention concerne un procédé et un appareil pour commander la vitesse d’une pompe d’une batterie d’oxydoréduction. Selon un mode de réalisation de la présente invention, le procédé de commande de la vitesse de la pompe d’une batterie d’oxydoréduction pour transférer un électrolyte stocké dans un réservoir d’électrolyte vers un empilement de cellules comprend les étapes de : mesure de la puissance d’entrée et/ou de la puissance de sortie de la batterie d’oxydoréduction ; mesure de la puissance de charge et/ou de la puissance de décharge de la batterie d’oxydoréduction ; calcul de la perte de puissance de la batterie d’oxydoréduction à l’aide de la différence entre la puissance d’entrée et la puissance de charge et de la différence entre la puissance de sortie et la puissance de décharge ; et réglage de la vitesse de la pompe selon la perte de puissance. Selon la présente invention, le rendement de puissance du système de batterie d’oxydoréduction peut être rendu maximal en commandant la vitesse de la pompe et la quantité de fourniture d’électrolyte selon la vitesse de la pompe afin de minimiser la perte de puissance du système de batterie d’oxydoréduction.
(KO)본 발명은 레독스 플로우 전지의 펌프 속도 제어 방법 및 장치에 관한 것이다. 본 발명의 일 실시예에 따른 전해질 탱크에 저장된 전해질을 셀 스택으로 전달하기 위한 레독스 플로우 전지의 펌프 속도를 제어하는 방법은, 상기 레독스 플로우 전지의 입력전력 및 출력전력 중 적어도 하나를 측정하는 단계, 상기 레독스 플로우 전지의 충전전력 및 방전전력 중 적어도 하나를 측정하는 단계, 상기 입력전력 및 상기 충전전력 간 차이 또는 상기 출력전력 및 상기 방전전력 간 차이를 이용하여 상기 레독스 플로우 전지의 전력손실을 계산하는 단계 및 상기 전력손실에 따라 상기 펌프 속도를 조절하는 단계를 포함한다. 본 발명에 따르면 레독스 플로우 전지 시스템의 전력손실이 최소가 되도록 펌프 속도 및 그에 따른 전해질 공급량을 제어함으로써 레독스 플로우 전지 시스템의 전력 효율을 극대화시킬 수 있다.
