Design and Research of VRLA Battery Condition Monitoring Integrated Chip Based on Wireless Communication Network

Abstract

Aiming at the problems of traditional battery monitoring devices such as large size, complicated wiring, single function, and high power consumption. This paper proposes a VRLA battery monitoring chip based on a wireless service (GPRS) network. By integrating the ZigBee wireless communication module, battery voltage, temperature, and internal resistance acquisition circuit, the volume is reduced to 50% of the existing acquisition module; error The test results show that the error of the battery state collection data is close to that of existing domestic and foreign products. Therefore, the battery condition monitoring chip developed in this paper can monitor the health status of valve-regulated lead-acid batteries in real time during the whole life cycle. It has the advantages of real-time, high precision, small size, convenient installation, and comprehensive functions.
