The invention relates to a battery management method, a battery management device, a vehicle and a storage medium. The battery management method comprises the steps of obtaining a first temperature and a second temperature of a battery module; the first temperature is the temperature of the cooling liquid, and the second temperature is the temperature of the battery; judging whether to request to heat the battery module and comparing the first temperature with the second temperature; in response to the condition that the battery module does not request heating and the first temperature and the second temperature meet the target temperature condition, constraining the output power of the regulating module; and the adjusting module is used for adjusting the temperature of the space communicated with the adjusting module and performing thermal management on the battery module. By adopting the method, the temperatures of the battery and the cooling liquid can be monitored when the battery module does not request for heating, the risk of passive heating of the battery caused by temperature rise of the cooling liquid along with the circulating liquid is reduced, and the output power of the adjusting module is reduced to slow down heating of the battery, so that the thermal management method of the battery module is improved.

    本申请涉及一种电池管理方法、电池管理装置、车辆以及存储介质。电池管理方法包括:获取电池模块的第一温度以及第二温度;第一温度为冷却液的温度,第二温度为电池的温度;判断是否请求加热电池模块以及比对第一温度以及第二温度;响应于电池模块未请求加热以及第一温度和第二温度符合目标温度条件,约束调节模块的输出功率;调节模块用于对其所连通的空间的温度进行调节以及对电池模块进行热管理。采用本方法能够在电池模块未请求加热时对电池与冷却液的温度进行监测,有利于降低冷却液随循环液升温导致电池被动加热的风险,并降低调节模块输出功率以减缓电池加热,从而有利于改善电池模块的热管理方法。
