The invention provides a battery switching system for an unmanned vehicle. The system is applied to an automatic driving vehicle or an unmanned vehicle and comprises two battery systems and a control unit, the two battery systems are used for sequentially supplying high-voltage power to the unmanned vehicle, and each battery system comprises a blocking diode; when any one of the two battery systems is in a power supply state, if the electric quantity of the current power supply battery system is lower than a preset threshold value and the electric quantity of the other battery system is higher than the other preset threshold value, the control unit controls the other battery system to be started, and the current power supply battery system and the other battery system supply power to the unmanned vehicle at the same time; at the moment, the blocking diode can prevent the other battery system from charging the current power supply battery system, and after the power supply state is maintained for a preset time, the control unit closes the current power supply battery system to complete switching between the two battery systems. According to the invention, automatic battery replacement of the unmanned vehicle is realized, the battery replacement cost and time consumption are reduced, and the battery replacement efficiency is improved.
本公开提供一种用于无人车的电池切换系统。该系统应用于自动驾驶车辆或者无人车,包括:两个电池系统以及控制单元,两个电池系统用于依次对无人车进行高压供电,每个电池系统均包括阻挡二极管;当两个电池系统中的任一电池系统处于供电状态时,若当前供电的电池系统的电量低于预定阈值,另一电池系统的电量高于另一预定阈值,控制单元控制另一电池系统开启,由当前供电的电池系统和另一电池系统同时向无人车供电;此时阻挡二极管能够阻止另一电池系统向当前供电的电池系统充电,同时供电状态维持预定时间后,控制单元关闭当前供电的电池系统,完成两个电池系统间的切换。本公开实现无人车的自动换电,降低换电成本及换电耗时,提升换电效率。
