Abstract
(EN)
An intelligent charging method and device for a pure electric automobile. The method comprises: after a charging unit is started, a low voltage output module supplying power to a control collection module and a battery information collection module; the control collection module receiving, from the battery information collection module, collected status information of a power battery to be charged currently, and selecting a charging mode according to the status information; and the control collection module charging the power battery according to the selected charging mode and along a charging curve set by a battery management system, or charging the power battery with a step current. To meet the requirements of an on-vehicle power battery system in a pure electric automobile, the method and device adopt a charging control policy of combining multi-stage constant current charging, quick pulse charging and constant voltage charging, thereby achieving an intelligent charging system capable of automatically switching charging mode, automatically determining charging status, and automatically stopping the vehicle.

L'invention concerne un procédé et un dispositif de charge intelligente pour une automobile tout électrique, le procédé comprenant les étapes suivantes : suite au démarrage d'une unité de charge, un module de sortie basse tension alimente en courant un module de collecte de régulation et un module de collecte d'informations de batterie ; le module de collecte de régulation reçoit du module de collecte d'informations de batterie des informations d'état collectées relatives à une batterie d'alimentation à charger, et sélectionne un mode de charge en fonction des informations d'état ; et le module de collecte de régulation charge la batterie d'alimentation en fonction du mode de charge sélectionné suivant une courbe de charge établie par un système de gestion de batterie, ou charge la batterie d'alimentation par un courant en échelon. Le procédé et le dispositif selon l'invention répondent aux exigences d'un système de batterie d'alimentation embarqué dans une automobile tout électrique en adoptant une politique de régulation de la charge consistant à associer une charge à courant constant échelonnée, une charge par impulsions rapide et une charge à tension constante de façon à obtenir un système de charge intelligente apte à commuter automatiquement le mode de charge, à évaluer automatiquement l'état de charge et à interrompre automatiquement la charge.
