The invention discloses a battery capacity determination method and apparatus, and an electronic device. The method comprises the steps that under the condition that it is detected that a current operation segment of a vehicle is ended, current operation parameter data of the vehicle in the operation segment is obtained, and the current operation segment is any one of a charging segment, a power grid feeding segment and a discharging segment; based on the current operation parameter data, a pre-trained available capacity evaluation model is adopted, the maximum available capacity of the battery of the vehicle at the ending moment of the current operation segment is obtained, and the multiple sets of sample data and the multiple historical operation segments are in one-to-one correspondence. According to the invention, the technical problem of low prediction accuracy of the maximum available capacity of the battery in a battery capacity determination method in the prior art is solved.

    本发明公开了一种电池容量确定方法、装置及电子设备。其中,该方法包括:在检测到车辆的当前运行片段结束的情况下,获取车辆在运行片段的当前运行参数数据,其中,当前运行片段为以下任意之一:充电片段,电网馈电片段、放电片段;基于当前运行参数数据,采用预先训练好的可用容量评估模型,得到车辆的电池在当前运行片段的结束时刻的最大可用容量,多组样本数据与多个历史运行片段之间存在一一对应的关系。本发明解决了相关技术中的电池容量确定方法存在的电池最大可用容量预测准确性低的技术问题。
