Abstract:
(EN) A battery equalization system, a vehicle, a battery equalization method, and a storage medium. The battery equalization system comprises: acquisition modules (12) used for acquiring parameter information of cells (111) in a battery pack (11); equalization modules (13) used for equalizing, by means of a storage battery (33), the cells (111) needing to be equalized, the storage battery (33) be connected to the cells (111) in the battery pack (11); control modules (14) used for controlling, when determining, according to the parameter information of the battery pack (11), there are cells (111) needing to be equalized in the battery pack (11), the equalization modules (13) to release power to the storage battery (33) by means of the cells (111) needing to be equalized. By controlling the equalization modules (13), the power of the cells (111) needing to be equalized is released to the storage battery (33), so that the technical problem in the related art of waste of electric energy during equalization of a battery equalization system by means of passive equalization is resolved.
(FR) L'invention concerne un système d'égalisation de batterie, un véhicule, un procédé d'égalisation de batterie, et un support d'informations. Le système d'égalisation de batterie comprend : des modules d'acquisition (12) servant à acquérir des informations de paramètres d'élément (111) dans un bloc-batterie (11); des modules d'égalisation (13) servant à égaliser, au moyen d'une batterie de stockage (33), les éléments (111) à égaliser, la batterie de stockage (33) étant connectée aux éléments (111) dans le bloc-batterie (11); des modules de commande (14) servant à commander, lorsqu'il est déterminé, selon les informations de paramètres du bloc-batterie (11), que des éléments (111) doivent être égalisés dans le bloc-batterie (11), les modules d'égalisation (13) de façon à libérer de l'énergie vers la batterie de stockage (33) au moyen des éléments (111) à égaliser. En commandant les modules d'égalisation (13), l'énergie des éléments (111) à égaliser est libérée vers la batterie de stockage (33), de sorte que le problème technique dans l'état de la technique lié à la perte d'énergie électrique pendant l'égalisation d'un système d'égalisation de batterie au moyen d'une égalisation passive est résolu.
(ZH) 一种电池均衡系统、车辆、电池均衡方法及存储介质,其中,电池均衡系统包括:采集模块(12),用于采集电池组(11)中单体电池(111)的参数信息;均衡模块(13),用于通过蓄电池(33)对需要开启均衡的单体电池(111)进行均衡处理,所述蓄电池(33)与所述电池组(11)中的单体电池(111)连接;控制模块(14),用于在根据所述电池组(11)的参数信息确定所述电池组(11)中有单体电池(111)需要开启均衡时,控制所述均衡模块(13)通过所述需要开启均衡的单体电池(111)放电给所述蓄电池(33)。通过控制均衡模块(13)将需要开启均衡的单体电池(111)放电给蓄电池(33),解决了相关技术中采用被动均衡方式的电池均衡系统在均衡时存在浪费电能的技术问题。
