The invention provides a battery protection method and device of an electric vehicle and electronic equipment. Before specific implementation, an energy discharge loop at least comprising a preset MOS (Metal Oxide Semiconductor) tube and a preset brake resistor can be connected in parallel in a target circuit which is connected with a controller and a battery in the electric vehicle in advance; in specific implementation, a first line voltage in a target circuit can be collected, and whether the first line voltage is greater than a preset first voltage threshold value is detected and judged; when the first line voltage is determined to be greater than the preset first voltage threshold value, the energy discharge loop can be triggered to be switched on, and the abnormal energy in the target circuit can be discharged by using the energy discharge loop, so that the abnormal energy in the target circuit can be automatically detected and found, and the detection efficiency of the abnormal energy in the target circuit is improved. And the abnormal energy in the target circuit is automatically triggered and released, so that the impact and damage of the abnormal energy in the target circuit to electrical structures such as a battery in the electric vehicle are effectively reduced, and the electric vehicle can run safely and stably.
本说明书提供了电动车的电池保护方法、装置和电子设备。具体实施前,可以预先在电动车内部连接有控制器和电池的目标电路中并联一个至少包含有预设的MOS管和预设的制动电阻的能量泄放回路;具体实施时,可以采集目标电路中的第一线路电压,并检测判断第一线路电压是否大于预设的第一电压阈值;在确定第一线路电压大于预设的第一电压阈值的情况下,可以触发接通上述能量泄放回路,并利用该能量泄放回路泄放掉目标电路中的异常能量,从而可以实现自动检测发现目标电路中的异常能量,并自动触发泄放掉目标电路中的异常能量,有效地减少了目标电路中异常能量对电动车中的电池等电气结构的冲击和破坏,使得电动车能够安全、稳定的运行。
