Title (EN) METHOD AND APPARATUS FOR DYNAMICALLY FOLLOWING STATE OF CHARGE OF BATTERY
(FR) PROCÉDÉ ET APPAREIL POUR SUIVRE DYNAMIQUEMENT L'ÉTAT DE CHARGE D'UNE BATTERIE
(ZH) 一种电池荷电状态动态跟随方法和装置
Abstract:
(EN) Disclosed are a method and apparatus for dynamically following a state of charge of a battery, the method comprising: acquiring a historical value of a state of charge of a battery during shutdown the last time; using a start-up correction method to obtain a correction value of the state of charge of the battery during start-up; determining whether a difference value between the historical value and the correction value of the state of charge of the battery is greater than a set value; and if so, according to a size relationship of the historical value and the correction value of the state of charge of the battery and whether the battery is in a charging state or in a discharging state after start-up, making a display value of the state of charge of the battery gradually transition from the historical value to a true value accumulated and obtained by means of the correction value combined with an ampere-hour integral method. Since a gradual transition process exists when a display value of a state of charge of a battery is adjusted, the display value of the state of charge of the battery does not hop.
(FR) L'invention concerne un procédé et un appareil de suivi dynamique d'un état de charge d'une batterie, le procédé consistant à : acquérir une valeur d'historique d'un état de charge d'une batterie pendant l'arrêt à la dernière période ; utiliser un procédé de correction de démarrage pour obtenir une valeur de correction de l'état de charge de la batterie pendant le démarrage ; déterminer si une valeur de différence entre la valeur d'historique et la valeur de correction de l'état de charge de la batterie est supérieure à une valeur définie ; et si tel est le cas, selon une relation de taille de la valeur d'historique et de la valeur de correction de l'état de charge de la batterie et si la batterie est dans un état de charge ou dans un état de décharge après le démarrage, faire qu'une valeur d'affichage de l'état de charge de la batterie passe progressivement de la valeur d'historique à une valeur réelle accumulée et obtenue au moyen de la valeur de correction combinée à un procédé intégré d'ampère-heure. Comme un processus de transition progressive existe lorsqu'une valeur d'affichage d'un état de charge d'une batterie est réglée, la valeur d'affichage de l'état de charge de la batterie ne saute pas.
(ZH) 一种电池荷电状态动态跟随方法和装置,其中方法包括:获取上次关机时电池荷电状态的历史值;采用开机矫正法得到开机时电池荷电状态的矫正值;判断电池荷电状态的历史值和矫正值之间的差值是否大于设定值;如果大于,则根据电池荷电状态的历史值与矫正值大小关系,以及开机后电池处于充电状态还是放电状态,使电池荷电状态的显示值由历史值逐渐过渡到由矫正值结合安时积分法累加得到的真实值。由于在对电池荷电状态的显示值进行调整时有逐渐过渡过程的存在,所以电池荷电状态的显示值不会发生跳变。
