The invention relates to the field of hybrid vehicles, and discloses a hybrid vehicle battery power control method, device and equipment and a hybrid vehicle. The method comprises the steps that the historical heating value and the in-pack temperature of a power battery are obtained; if the historical calorific value is greater than the preset heat upper limit and the in-pack temperature is greater than the preset temperature upper limit, acquiring a dynamic power limit value associated with the power battery; and controlling the output power of the power battery according to the dynamic power limit value. The problem that the temperature of the power battery of the hybrid electric vehicle is too high or the temperature rise rate is too high is solved, and the output power of the power battery can be regulated in advance, so that the excessive rise of the temperature of the battery is inhibited, the safety of the power battery is improved, and the driving smoothness of the whole vehicle is also improved.

    本发明涉及混动汽车领域,本发明公开了混动汽车电池功率控制方法、装置、设备及混动汽车,其方法包括:获取动力电池的历史发热量和包内温度;若历史发热量大于预设热量上限,且包内温度大于预设温度上限,获取与动力电池关联的动态功率限值;根据动态功率限值控制动力电池的输出功率。本发明解决了混动汽车动力电池温度过高或温升速率过快的问题,可以实现提前对动力电池的输出功率进行调控,从而抑制了电池温度过度上升,既提升了动力电池的安全性,也提升整车驾驶的平顺性。
