The invention discloses a battery discharge cooling method of a hybrid electric vehicle, which comprises the following steps: starting battery cooling when the actual electric quantity of a battery is lower than a first electric quantity threshold value and the highest temperature of the battery exceeds a first cooling starting threshold value when a power mode is a pure electric mode; when the actual electric quantity of the battery is not lower than the first electric quantity threshold value and the highest temperature of the battery exceeds a second cooling starting threshold value, starting battery cooling; the power mode is a hybrid power mode, and when the actual electric quantity of the battery is lower than a second electric quantity threshold value and the highest temperature of the battery exceeds a third cooling starting threshold value, battery cooling is started; when the actual electric quantity of the battery is not lower than the second electric quantity threshold value and the highest temperature of the battery exceeds a fourth cooling starting threshold value, starting battery cooling; the first cooling starting threshold value > the second cooling starting threshold value > = the third cooling starting threshold value > the fourth cooling starting threshold value. The method can improve the battery energy utilization rate. The invention also discloses a battery discharge cooling device, electronic equipment and a computer readable storage medium.

    本发明公开了混合动力汽车的电池放电冷却方法,包括:动力模式为纯电模式,当电池实际电量低于第一电量阈值时,电池最高温度超过第一冷却开启阈值,开启电池冷却;当电池实际电量不低于第一电量阈值时,电池最高温度超过第二冷却开启阈值,开启电池冷却;动力模式为混合动力模式,当电池实际电量低于第二电量阈值时,电池最高温度超过第三冷却开启阈值,开启电池冷却;当电池实际电量不低于第二电量阈值时,电池最高温度超过第四冷却开启阈值,开启电池冷却;第一冷却开启阈值>第二冷却开启阈值≥第三冷却开启阈值>第四冷却开启阈值。上述方法能提高电池能量利用率。本发明还公开了电池放电冷却装置、电子设备和计算机可读存储介质。
