摘要

锂离子电池作为机器人的动力源，其温度特性直接影响到机器人的工作性能。通过温升试验和放电试验，深入研究了锂离子电池的热特性，设计了动力电池PTC热管理系统，提高了机器人的性能。电池表面热分布表明，由于铝的导热性，电池表面温差小于0.5℃，放电测试表明，PTC热管理系统可以有效地加热锂离子电池组，在-20℃时可提供47Ah的容量，在20℃时可提供约93%的容量。

Research of thermal management technology for battery of robot working in alpine region

As the power source of robot, the temperature characteristics of the lithium-ion battery directly affect the robot working performance. The thermal characteristics of lithium-ion battery have been intensively studied through both temperature rise tests and the discharging tests, and the PTC thermal management system of power battery was designed to enhance the performance of robot. Battery surface heat distribution demonstrated that battery surface temperature difference was less than 0.5°C because of aluminum thermal conductivity, and the discharging test showed that the PTC thermal management system could heat the lithium-ion battery pack effectively, which could deliver a capacity of 47Ah at -20°C, about 93% at 20°C.
