Based on the proposed concept of new energy battery,the goal of battery standards was formulated,and the battery management system for battery replacement standardization was established.Using the second-order circuit equivalent battery model and corresponding real-time estimation algorithm for the charge state,combined with analog front-end chips ml5238 and ml610q486 microcontrollers,the core of a standardized battery management system was implemented,and a new battery management system that can be put into commercial application was realized.The system with a processing time of less than 100 μs,an accuracy rate of up to 99.2%,and a cost reduction of 30%compared to similar systems.
