Abstract
Battery management system(BMS) is a main component in the battery pack system for electric vehicle(EV). The function of BMS is to monitor battery cells such as; cell voltage, cell temperature, current in the battery pack. Moreover BMS also able to balance the voltage of the cells so the different in voltage of the cells can be minimized. By having many of these function, BMS can identify battery health based on these parameters. With such important function,in this paper BMS were tested to determine its reliability. The standart testing for BMS reliability is Environment test. In the environment test, some things that are conducted in the environment test are initial temperature cycling, rapid temperature change, mechanical shock and mechanical vibration. From the environment test can be generated information to asses the quality of the BMS in accordance with its function. Furthermore it can reduce the cost to inspect every battery cells in the packs. With environment test as a basis for BMS reliability tester, hopefully good quality is obtained. Future development in BMS reliability testing can also conducted to improve the reliability.
