AI Technical Summary

Technical Problem

During the handover process of electric vehicles, the concentrated handover time of users leads to congestion at battery swapping stations and a poor user experience. Existing technologies cannot effectively solve the problem of unclear electricity charges.

Method used

A battery management system and method are provided, which improves user experience by recording the remaining amount of the vehicle battery, generating the handover power difference, and determining the power deficit between users at a preset settlement node.

Benefits of technology

By recording and integrating remaining battery levels, the system accurately calculates the difference in battery power between users, solving the problem of unclear electricity bills and improving the user handover experience.

Abstract

本发明实施例公开了一种电池管理系统和方法。本发明实施例的电池管理系统包括车载电池和电池管理模块，车载电池被配置为向目标车辆供电以及向电池管理模块上报车载电池余量，电池管理模块被配置为响应于到达交接班节点，确定目标车辆的车载电池余量，根据车载电池余量生成对应的车载电池余量记录，响应于到达预设结算节点，根据目标车辆在当前结算周期内的车载电池余量记录分别确定目标车辆对应的各个用户的交接电量差，根据目标车辆对应的多个用户分别对应的交接电量差和电单价，定结算结果。上述系统以交接班时刻的车载电池余量为依据生成车载电池余量记录，进而在预设结算节点整合以确定使用同一车辆的用户间的电量亏欠情况，提高用户体验感。
