By integrating heat pipes, heat-conducting glue, phase change materials, and micro-channel plates, the designed thermal management system can effectively cool and heat li-ion batteries in various ambient temperatures.
A thermal management system (TMS) including heat pipes, heat-conducting glue, phase change materials (PCM), and micro-channel plates is built in this research. The heat pipes and heat-conducting glue can solve the problem of poor thermal conductivity and large internal temperature difference (T-d) of TMS including PCM and liquid cooling. The micro-channel plates can solve the problem that TMS combined with the PCM and the heat pipes is difficult to transfer heat. The designed TMS can cool and heat li-ion battery. Through the li-ion battery discharge test experiment by 1C, 2C, and 3C, the li-ion battery heating power is obtained. The temperature change curve of li-ion batteries at 1C, 2C, 3C discharge and when ambient temperature (T-a) is -20 degrees C, -10 degrees C, 0 degrees C, and 20 degrees C are studied. When the T-a is lower than 0 degrees C, the designed TMS can heat the li-ion battery to 20 degrees C, and make the T-d inside the li-ion batteries approach 0 degrees C within a short period.
