The invention relates to a lithium battery for an electric bicycle, which comprises a shell for protecting a lithium battery pack, a heating film is connected with a power bank through a portable power socket for temperature compensation, heat is exchanged through a heat conduction piece to realize heat dissipation and heat absorption, a hidden BMS-PCB structure prevents man-made damage and is antitheft, and LFP cells are adopted to form the lithium battery pack. The heat transfer guide sheets are installed between the battery cells in a matched mode to collect or release heat, the heat is collected through the heat collection sheets, then heat exchange is conducted through the cooling fins, and the double functions of heat dissipation and temperature compensation in cold seasons are achieved. The lithium battery has a good use effect, can also be used for power supplies of electric tricycles and electric motorcycles, and is suitable for application in cold regions.

    本发明涉及一种电动自行车用的锂电池,包括保护锂电池组的外壳,加热膜通过便携电源插座连接充电宝进行补温,热量通过导热件进行交换以实现散热和吸热,隐蔽式BMS‑PCB板结构防止人为破坏并防盗,采用LFP电芯组成锂电池组,各电芯间配合安装有传热导片进行集热或放热,热量通过集热片收集,再通过散热片进行热交换,具有散热和在寒冷季节补温的双重作用。该锂电池具有良好的使用效果,也可以用于电动三轮车、电动摩托车的电源使用,适合于寒冷地域的应用。
