Title
(EN) BATTERY HEATING SYSTEM AND CONTROL METHOD THEREFOR
(FR) SYSTÈME DE CHAUFFAGE DE BATTERIE ET SON PROCÉDÉ DE COMMANDE

Abstract
(EN)
A battery heating system and a control method therefor, which relate to the field of battery power. The battery heating system comprises a main positive switch (K1), a main negative switch (K2), an inverter (P2), a motor (P3) and a battery management module (P4); the inverter (P2) comprises a first-phase bridge arm, a second-phase bridge arm and a third-phase bridge arm which are connected in parallel; a motor controller (P20) in the inverter (P2) is used to output drive signals to a target upper bridge arm switch module and a target lower bridge arm switch module as well as to control a switch module of an upper bridge arm of any one of the three bridge arms and a switch module of a lower bridge arm of at least one bridge arm other than the bridge arm where the target upper bridge arm switch module is located to be periodically turned on and off; and the battery management module (P4) is used to collect state parameters of a battery pack (P1). When the state parameters of the battery pack (P1) meet a preset heating condition, a control signal is sent to the motor controller (P20) so as to control the motor controller (P20) to output a drive signal. The present technical solution may improve the heating efficiency of a battery pack.

L'invention concerne un système de chauffage de batterie et son procédé de commande qui se rapportent au domaine de l'alimentation des batteries. Le système de chauffage de batterie comprend un commutateur positif principal (K1), un commutateur négatif principal (K2), un onduleur (P2), un moteur (P3) et un module de gestion de batterie (P4) ; l'onduleur (P2) comprend un bras de pont de première phase, un bras de pont de deuxième phase et un bras de pont de troisième phase qui sont connectés en parallèle ; un contrôleur de moteur (P20) dans l'onduleur (P2) est utilisé pour délivrer des signaux d'entraînement à un module de commutation de bras de pont supérieur cible et à un module de commutation de bras de pont inférieur cible ainsi qu'à commander un module de commutation d'un bras de pont supérieur de l'un des éléments quelconque parmi les trois bras de pont et un module de commutation d'un bras de pont inférieur d'au moins un bras de pont autre que le bras de pont où le module de commutation de bras de pont supérieur cible est situé de façon à être allumé et éteint périodiquement ; et le module de gestion de batterie (P4) est utilisé pour collecter des paramètres d'état d'un bloc-batterie (P1). Lorsque les paramètres d'état du bloc-batterie (P1) satisfont une condition de chauffage prédéfinie, un signal de commande est envoyé au contrôleur de moteur (P20) de façon à commander le contrôleur de moteur (P20) à délivrer un signal d'entraînement. La présente solution technique peut améliorer l'efficacité de chauffage d'un bloc-batterie.
