A Formation System of Large-Capacity Power Li-Ion Battery

Abstract:

This paper designed a large-capacity Li-ion battery formation system, and illustrated its composition and working principle. The formation system uses a programmable voltage-limiting and constant-current control circuit with voltage-limiting protection function to prevent Li-ion battery over-charge and over-discharge. The system consists of a upper computer (server) and a number of lower computers (formation units) linked with 485 bus. The server can monitor formation process and record formation data in real-time. By testing, the system has good characteristics, such as large charge and discharge current, high control accuracy, multiple-step programming, etc., and it can meet the needs of a large-scale power Li-ion battery formation.
