The invention provides a battery electric quantity calibration system and method and an electric vehicle, and relates to the technical field of electric vehicles, and the system comprises an electric quantity calibration module and an electric quantity management module which are in signal connection; the electric quantity calibration module is used for collecting battery power-off information or battery non-power-off information of the electric vehicle and sending the battery power-off information or the battery non-power-off information to the electric quantity management module when the electric vehicle is powered on again; after the electric vehicle is powered on again, the electric quantity management module can receive the battery power-off information or the battery non-power-off information sent by the electric quantity calibration module, and the electric quantity management module can recalculate the remaining electric quantity of the battery according to the battery power-off information or the battery non-power-off information. Therefore, the remaining electric quantity reserved when the electric quantity management module is powered off last time can be calibrated, and the remaining electric quantity of the current battery of the electric vehicle can be accurately displayed through a recalibration method after the battery is replaced or the battery is placed for a long time.
本申请提供一种电池电量校准系统及方法、电动车,涉及电动车技术领域,系统包括信号连接的电量校准模块和电量管理模块;电量校准模块用于采集电动车的电池断电信息或电池非断电信息,并在电动车重新上电时,向电量管理模块发送电池断电信息或电池非断电信息;在电动车重新上电后,电量管理模块便可以接收到电量校准模块所发送的电池断电信息或电池非断电信息,并且电量管理模块会根据电池断电信息或电池非断电信息,重新计算电池的剩余电量,以便于能够对电量管理模块上次断电时所保留的剩余电量进行校准,使得电动车能够在更换电池或电池久置后通过重新校准的方法精准显示当前电池的剩余电量。
