The invention discloses a liquid-cooled battery for an electric motorcycle, belonging to the technical field of electric motorcycles. The liquid-cooled battery comprises a sealed box body, a controller element and a battery cell group, wherein the battery cell group is composed of a plurality of individual battery cells, insulating cooling liquid is injected into the sealed box body, the battery cell group is integrally soaked in the insulating cooling liquid, gaps are formed among the plurality of individual battery cells, a first temperature sensor is arranged in the battery cell group, and the first temperature sensor is connected with a charging circuit of the battery cell group in series. The liquid-cooled battery further comprises a heating circuit, wherein the heating circuit is connected with the charging circuit of the battery cell group in parallel, a second temperature sensor is connected with the heating circuit in series, the first temperature sensor has a negative temperature coefficient, and the second temperature sensor has a positive temperature coefficient. Compared with the prior art, the liquid-cooled battery of the invention has the beneficial effects that the battery cell group is better in heat dissipation and more uniform in temperature when being used at normal temperature, the normal charging and working of the battery cell group can be well ensured at low temperature, and use is very convenient.

    本发明公开了一种电动摩托车技术领域的电动摩托车液冷电池,包括密封箱体、控制器元件和电芯组,电芯组由多个个体电芯组成,密封箱体内注有绝缘冷却液,电芯组整体浸泡在绝缘冷却液中,多个个体电芯之间设有间隙,电芯组内设有第一温度传感器,第一温度传感器和电芯组的充电电路串联,还包括有加热电路,加热电路与电芯组的充电电路并联,加热电路上串联有第二温度传感器,第一温度传感器为负温度系数,第二温度传感器为正温度系数;本发明相较于现有技术的有益效果为常温下使用可以使得电芯组散热更好,温度更加的均匀,低温情况下也能够很好的保证电芯组的正常充电和工作,非常的方便。
