A Simulated System of Battery-Management-System to test Electric Vehicles Charger

This paper presents the implementation of a Simulated System of Battery-Management-System (SS-BMS) based on a computer with CAN communication interface to test the Electric Vehicles (EV) Charger. The SS-BMS includes the mathematical models to simulate the electrical and thermal properties of power battery, provides users with defining a variety of mode to simulate different charging circumstances and real-time information, such as single voltage, single temperature and state of charge (SOC) estimation by taking real-time charging current into account. With the SS-BMS, it is able to make the testing process more controllable and the results more reliable.
