Abstract
(EN)
A method and apparatus for rapidly detecting the remaining capacity and the state of health of a storage battery. The method comprises the following steps: enabling a storage battery to perform instantaneous large-current discharging via a controllable discharging circuit, monitoring a discharging current in the discharging circuit in the process via a current sampling circuit, synchronously monitoring an end voltage of the storage battery via a voltage sampling circuit, and measuring an internal resistance of the storage battery according to a direct-current discharging method, wherein the discharging circuit and the voltage sampling circuit are connected in parallel with two wiring columns of the storage battery, so that the internal resistance of the storage battery is measured according to a Kelvin four-wire system measuring method, and the maximum discharging current, a load voltage and internal resistance data of the storage battery are acquired; and according to a related relationship model, calculating the SOC and SOH of the storage battery. By means of the method, the remaining capacity and the state of health of a storage battery can be accurately detected on-line.

L'invention concerne un procédé et un appareil pour détecter rapidement la capacité restante et l'état de santé d'une batterie rechargeable. Le procédé comprend les étapes suivantes, consistant à : permettre à une batterie rechargeable d'effectuer une décharge instantanée à courant élevé par l'intermédiaire d'un circuit de décharge commandable, surveiller un courant de décharge dans le circuit de décharge dans le processus par l'intermédiaire d'un circuit d'échantillonnage de courant, surveiller de manière synchrone une tension aux bornes de la batterie rechargeable par l'intermédiaire d'un circuit d'échantillonnage de tension, et mesurer une résistance interne de la batterie rechargeable selon un procédé de décharge de courant continu, le circuit de décharge et le circuit d'échantillonnage de tension étant connectés en parallèle à deux colonnes de câblage de la batterie rechargeable, de telle sorte que la résistance interne de la batterie rechargeable est mesurée selon un procédé de mesure de système à quatre fils de Kelvin, et le courant de décharge maximal, une tension de charge et des données de résistance interne de la batterie rechargeable sont acquis ; et selon un modèle de relation associé, calculer l'état de charge (SOC) et l'état de santé (SOH) de la batterie rechargeable. Au moyen du procédé, la capacité restante et l'état de santé d'une batterie rechargeable peuvent être détectés en ligne avec précision.
