Abstract
This paper compares the influences of two different charging strategies on the performance of the Electric Vehicle (EV) charging system, including the EV battery, the Battery Management System (BMS), and the power electronic converter. Firstly, the two types of EV charging strategies are explained. Herein, the characteristics, the influences on the EV battery, and the respective requirements for the hardware and communication of the BMS and power electronic converter are summarized. Secondly, a simulation case study is conducted to investigate the influences of the two charging strategies on the performance of a typical power electronic converters employed as a back-end converter of a fast EV charger. A modular 50kW DC-DC EV charger constructed with five parallel-connected 10kW Phase-Shift Full-Bridge (PSFB) DC-DC converter is modelled with two different charging strategies, and two comparison metrics are proposed for a benchmark: the charging-cycle efficiency and the installation utilization rate. The results show that these two comparison metrics are influenced by the charging strategies of the EV.
