Abstract
The utility model provides a battery module and an automobile, and relates to the technical field of batteries. The battery module comprises a shell, a battery cell stacking body, a heating piece and a cooling plate, the heating element is arranged on the side wall of the battery cell stacking body, and the heating element can generate heat and conduct the heat to the battery cell stacking body, so that the battery cell stacking body has relatively high temperature in a low-temperature environment, and the battery module runs reliably. The cooling plate is arranged at the bottom of the battery cell stacking body and can support and mount the battery cell stacking body. According to the battery module disclosed by the utility model, the cooling plate and the heating piece are arranged at the bottom and the side part of the battery cell stacking body, so that the cooling plate and the heating piece can be positioned at different parts of the battery cell stacking body, mutual interference and influence of the cooling plate and the heating piece can be avoided to a certain extent, meanwhile, the surface space of the battery cell stacking body is fully utilized, and the battery module disclosed by the invention is more reasonable in structure. An air conditioner refrigerant of an automobile can circularly flow through the heat dissipation channel, so that the refrigerant can directly absorb heat generated by the battery cell stacking body, and the temperature of the battery module can be reduced.
