The invention relates to the technical field of battery protection, and discloses an idle-speed-based lithium battery protection method, device and equipment and a storage medium, and the method comprises the steps: calculating the current rotating speed of a BSG motor through a preset power calculation strategy when the current driving working condition of a target vehicle is idle speed; when the first output current of the target lithium battery is larger than a preset current threshold value and the electric quantity SOC of the target storage battery is smaller than a preset safety threshold value, the current rotating speed of the target engine is adjusted through the target output power based on the generated power; when the current driving working condition is the idle speed, the first output current of the target lithium battery is larger than the preset current threshold value, and the electric quantity SOC is smaller than the preset safety threshold value, the target lithium battery is protected by adjusting the current rotating speed of the target engine; compared with the prior art, a BSG motor is replaced by a motor with higher power, so that the lithium battery is prevented from discharging, the risk of power shortage of the lithium battery can be effectively reduced, and the improvement cost is reduced.

    本发明涉及电池保护技术领域,公开了一种基于怠速的锂电池保护方法、装置、设备及存储介质,所述方法包括:在目标车辆的当前行驶工况为怠速时,通过预设功率计算策略对BSG电机的当前转速进行计算;在目标锂电池的第一输出电流大于预设电流阈值且目标蓄电池的电量SOC小于预设安全阈值时,基于发电功率通过目标输出功率对目标发动机的当前转速进行调节;由于本发明是通过在当前行驶工况为怠速且目标锂电池的第一输出电流大于预设电流阈值且电量SOC小于预设安全阈值时,通过调节目标发动机的当前转速以保护目标锂电池,相较于现有技术通过功率更强的电机替换BSG电机以避免锂电池放电,能够有效降低锂电池的亏电风险,且降低改善成本。
