Abstract: | |
High energy, high power and compact size batteries are demanded on the current market of battery applications. As battery has turned out to be one of the essential components in driving high energy-consuming products, the development of battery is greatly important. Battery Management System (BMS) has become a very important core technology to play the major roles in performing safety monitoring, and effective control and management of the battery pack to improve the service performance and reliability of the vehicle while it is running. In this paper, the Coulomb integral measurement method was adopted as a checking device to compute the battery capacity as it can be implemented on different battery types and has an average current measurement error rate of only 1%. While the general testing devices require the battery to go through a complete charging process, the integrated voltage measurement method has the advantage to effectively save the battery checking time. When a 3000mAh battery is used in checking its performance, the normal checking time of 155 minutes can be reduced to 45 minutes while using the checking method adopted by the method proposed in the paper. |
