The invention discloses a new energy automobile emergency energy management method, device and equipment and a storage medium, and the method comprises the steps: sending an emergency energy management instruction to a battery system when a three-level under-voltage fault sent by the battery system is received, so that the battery system evaluates the state of a battery cell according to the emergency energy management instruction; when the state of the battery cell meets the emergency energy management requirement, the battery system is controlled to adjust a three-level under-voltage threshold value according to the real-time state of the battery cell, so that the battery system estimates the current SOC according to the adjusted three-level under-voltage threshold value; the current SOC sent by the battery system is received, and the remaining mileage is estimated based on the current SOC; and selecting a target emergency processing mode according to the remaining mileage. The three-level under-voltage threshold value is adjusted on the premise that the safety of the battery cell is ensured according to the cycle life of the battery cell, the current SOC and the remaining mileage are re-estimated, and compared with the prior art, the vehicle using cost of a user can be effectively reduced, and the vehicle using experience of the user can be improved.

    本发明公开了一种新能源汽车应急能量管理方法、装置、设备及存储介质,该方法包括:当接收到电池系统发送的三级欠压故障时,发送应急能量管理指令至电池系统,以使电池系统根据应急能量管理指令评估电芯状态;在电芯状态满足应急能量管理需求时,控制电池系统根据电芯实时状态调整三级欠压阈值,以使电池系统根据调整后的三级欠压阈值估算当前SOC;接收电池系统发送的当前SOC,并基于当前SOC估算剩余里程;根据剩余里程选取目标应急处理方式。本发明根据电芯的循环寿命在确保电芯安全前提下调整三级欠压阈值,并重新估算当前SOC和剩余里程,相比于现有技术,本发明不仅能够有效降低用户用车成本,还能提高用户的用车体验。
