Application of Lithium-Ion Battery Thermal Management System in Electric Vehicle Simulation
Lithium-ion batteries are becoming increasingly a popular energy storage form in electric vehicles (EVs) industry. However, the performance of EVs depends largely on the properties of batteries. If the cell temperature is too high or too low, it will result in some irreversible damage to the battery, e.g. the capacity, cycle life and energy efficiency would decrease significantly. The thermal runaway phenomenon will cause fire and even explosion. Although varieties of battery thermal management systems (BTMSs) have been researched, most were evaluated under experimental condition with a constant current rate. Thus, in this research, a liquid cooling methodology and the first-order Thevenin equivalent circuit model are firstly adopted to develop a BTMS. Then the practicability is validated with the current pulses generated by a battery electric bus driving model. Finally, the BTMS is able to control the temperature in the range of 20–40 ℃ for the whole day operation.
