| Abstract: | Thermal management of lithium-ion (Li-ion) battery remains a challenge before widespread commercialization occurs. To solve this problem, the micro heat pipe arrays (MHPAs) were used in cooling and heating system. Temperatures were measured with and without MHPAs during the charge-discharge cycle at 1C rate. The temperature of the battery pack and temperature differences were effectively reduced by the system, and the temperature and the temperature difference value were controlled within 40℃ and 5℃, respectively. The battery performance at low temperature was improved by heating sheet. The results of the experiments reveal the enhanced stability and safety during the continuous charge-discharge cycle. |
