摘要:

利用超级电容的功率密度高及可大电流充放电等特点,提出并设计了锂电池与超级电容双能源电电混合动力系统,建立了基于交流电力测功机的混合动力系统在环综合测试台架。采用70.4V/40A·h的磷酸铁锂电池组与48.6V/165F超级电容模组进行混合,并设计了基于综合测试台架的后向工况测试流程。最后采用UDDS动态工况,完成对基于模糊PID控制的双能源能量管理策略系统的在环测试。测试结果表明,通过混合结构及能量管理策略,锂电池组的充放电电流均限制在1C范围内,超级电容承担大部分电流波动,保护了锂电池组。

Abstract:

A hybrid power system combined lithium battery and super capacitor was proposed and designed by using super capacitor's advantages, such as high power density and better charge and discharge properties. A powertrain in a loop test bench was established based on the AC electrical dynamometer. Secondly, the test station powered by a 70.4V/40A·h lithium battery pack and two 48.6V/165F super capacitor bank was designed and constructed on the basis of stand-alone module. The backward test method was designed for the powertrain test bench. Finally, a fuzzy-PID controller was devised for the energy management of hybrid powertrain and an UDDS driving cycle was carried out. The test results show that the charge and discharge currents of lithium battery pack are restricted below 1C, and the most current fluctuation is undertook by super capacitor bank, which can protect the lithium battery pack.

Key words: lithium battery, super capacitor, UDDS driving cycle, powertrain in loop test, energy management of hybrid powertrain
