Abstract
(EN)
Disclosed in the present application are a battery heating system and a control method therefor. The system comprises: a first switch connected to a positive pole of a battery pack, a second switch connected to a negative pole of the battery pack, a switch assembly connected between the first switch and the second switch, a motor connected to the switch assembly, and a main controller, the first switch, the second switch, the switch assembly, and the main controller being integrated inside of the same housing; the main controller is used for determining, according to state parameters of the battery pack, that the battery pack needs to be heated and sending a battery heating request to an overall vehicle controller, such that the overall vehicle controller sends a battery heating instruction to the main controller according to the battery heating request when determined that a vehicle is in a standing state and the motor is not in operation; and the main controller is used for controlling the first switch, the second switch, and the switch assembly according to the battery heating instruction so as to heat the battery pack. According to embodiments of the present application, costs are reduced and heating efficiency is improved.

La présente invention concerne un système de chauffage de batterie et son procédé de commande. Le système comprend : un premier commutateur connecté à un pôle positif d'un bloc-batterie, un second commutateur connecté à un pôle négatif du bloc-batterie, un ensemble commutateur connecté entre les premier et second commutateurs, un moteur connecté à l'ensemble commutateur, et un dispositif de commande principal, le premier commutateur, le second commutateur, l'ensemble commutateur et le dispositif de commande principal étant intégrés dans le même boîtier ; le dispositif de commande principal sert à déterminer, en fonction de paramètres d'état du bloc-batterie, que le bloc-batterie doit être chauffé, et à envoyer une demande de chauffage de batterie à un dispositif de commande de véhicule global, de telle sorte que le dispositif de commande de véhicule global envoie une instruction de chauffage de batterie au dispositif de commande principal selon la demande de chauffage de batterie lorsqu'il est déterminé qu'un véhicule est dans un état stationnaire et que le moteur n'est pas en fonctionnement ; et le dispositif de commande principal sert à commander le premier commutateur, le second commutateur et l'ensemble commutateur selon l'instruction de chauffage de batterie de façon à chauffer le bloc-batterie. Selon des modes de réalisation de la présente invention, les coûts sont réduits et l'efficacité de chauffage est améliorée.
