英文摘要：

To meet the requirement of lithium ion battery discharge simulation in the process of development and production of portable devices, two simulation principles were studied and compared and a developing method of lithium ion battery discharge simulation power supply was proposed. An experiment was carried out to measure the error between the waveforms generated by the simulation power supply by this method and by the discharge of lithium ion battery. The results show that relative error is not more than 0.54%. The result of the present work implies that the simulation power supply developed by this method is accurate and reliable enough to use in practical engineering applications.
