The invention discloses a battery temperature control method, device and equipment and a readable storage medium, battery attributes sent by a vehicle at the current moment are input into a pre-trained battery temperature prediction model, a feature map is obtained through a feature map extraction unit in the battery temperature prediction model, and according to the battery attributes at the current moment and the feature map, a battery temperature prediction result is obtained. And obtaining an attention weight matrix through the cross self-attention unit, obtaining the battery temperature at the next moment according to the attention weight matrix and the battery attribute at the current moment, and returning the battery temperature at the next moment to the vehicle, so that the vehicle performs temperature control on the battery according to the battery temperature at the next moment. Therefore, the battery temperature at the next moment is predicted based on the pre-trained battery temperature prediction model, the accuracy of the battery temperature at the next moment is not influenced even if the time interval between the current moment and the next moment is relatively long, so that the accuracy of battery temperature prediction is improved; and the control precision of the battery temperature and the performance of the vehicle battery are improved.

    本说明书公开了一种电池温度的控制方法、装置、设备及可读存储介质,将车辆发送的当前时刻的电池属性输入到预先训练的电池温度预测模型,通过其中的特征图提取单元得到特征图,根据当前时刻的电池属性和特征图,通过交叉自注意力单元得到注意力权重矩阵,根据注意力权重矩阵和当前时刻的电池属性得到下一时刻的电池温度,将下一时刻的电池温度返回给车辆,使得车辆根据下一时刻的电池温度对电池进行温度控制。可见,基于预先训练的电池温度预测模型预测下一时刻的电池温度,即使当前时刻和下一时刻的时间间隔较长,也不会影响下一时刻的电池温度的准确性,从而提高的电池温度预测的准确性,进而提高了电池温度的控制精度和车辆电池的性能。
