Battery management system (BMS) is the most important part of an electronic vehicle (EV), and the management module for single cell is the most important collection part of BMS. It provides cells’ data and realizes cells management for BMS. In this paper, the design and realization of the management module for single cell is presented. It can collect real-time voltage and temperature data of cells, and carry on the necessary processing for such data, and then upload these data to the main control module in the battery management system. The design can also equalize the cells, and made their voltage remain in a standard. For the proposed design scheme, the microcontroller PIC24F16KA101 is used as the core part, and the multi-cell addressable battery stack monitor LTC6802 is utilized as the collection part. Moreover, the design of multi-channel data collection and management system, and the design of software and hardware for interface are given. The practical experimental results show that the system can realize the real-time multi-channel signal collection, offer useful data for battery management system, and equalize the cells at power on or power off situation, so as to guarantee the battery consistency.
