(BMS) Electric vehicle battery management system-a full set of design data for the main control board and the inspection board

As one of the core components of electric vehicles, the battery management system is a key technology to solve the safety problems, long-term use problems, and energy management problems of electric vehicle power batteries. A simple battery management system was developed and realized by analyzing the related characteristics of the commonly used power battery-lithium ion battery and combining the related situation of electric vehicle batteries. Through this system, basic information such as voltage, current and temperature of the battery pack of electric vehicles can be measured, and through this information, the open circuit voltage method and the ampere-hour integration method are used to estimate the remaining power of the electric vehicle and give Limit reference value alarm, and at the same time, provide interactive mode for user parameter setting.
