The invention relates to the technical field of vehicle batteries, in particular to a battery temperature control method and a vehicle-mounted battery control device. The battery temperature control method comprises the following steps: acquiring the real-time temperature of a high-voltage plug connector of a target battery; judging whether the real-time temperature is lower than a first threshold value or not; if the detected real-time temperature is smaller than the first threshold value, the maximum charging and discharging power of the target battery is controlled to be equal to the rated power of the target battery; if detecting that the real-time temperature is greater than or equal to the first threshold value, judging whether the target battery is in a charging state or a discharging state; if the target battery is in the discharging state, controlling the maximum charging and discharging power of the target battery according to a first rule; and if so, controlling the maximum charging power of the target battery according to a second rule. Therefore, the problems that the temperature of the battery is too high in the charging and discharging process and fire disasters are prevented are solved.
本发明涉及车辆电池技术领域,具体而言,涉及一种电池温度控制方法及车载电池控制装置。电池温度控制方法包括:获取目标电池的高压插接件的实时温度;判断实时温度是否低于第一阈值;如果检测到的实时温度小于第一阈值,控制目标电池的最大充放电功率等于目标电池的额定功率;如果检测到实时温度大于等于第一阈值,判断目标电池处于充电状态还是放电状态;如果为放电状态,按照第一规则控制目标电池的最大充放电功率;如果为充电状态,按照第二规则控制目标电池的最大充电功率。这样就解决了电池在充放电过程中温度过高以及预防火灾发生的问题。
