The invention discloses a battery module structure. The structure comprises an aluminum plate internally provided with a cooling channel and a plurality of insertion holes vertically formed in the aluminum plate, cylindrical battery cells are inserted into the insertion holes, the cooling channel is filled with silicone oil, a cooling channel opening is formed in the side wall of the aluminum plate, and the cooling channel opening is communicated with the insertion holes through the cooling channel; when a battery is at a high temperature, the low-temperature cooling liquid flows through the aluminum plate cooling channel for convective heat exchange and then takes away battery heat conducted by the aluminum plate; and when the battery needs to be preheated, the thermal-state cooling liquid transfers heat to the aluminum plate, so that the battery pack is preheated. The temperature management problem of the battery pack can be solved, and the battery pack temperature equalization capability is improved.

    本发明公开了一种电池模块结构,包括内设冷却通道的铝板和竖直开设在铝板上的多个插孔,所述的插孔中插放有圆柱形电芯,所述的冷却通道内填充有硅油,所述的铝板侧壁设置有冷却通道口,所述的冷却通道口通过冷却通道与插孔连通;在电池高温时,低温冷却液流经铝板冷却通道进行对流换热后将铝板传导的电池热量带走;在电池需要预热时,热态冷却液将热量传给铝板,从而对电池组进行预热。本发明能够解决电池组温度管理问题,提高电池组均温能力。
