Abstract:

In order to meet the needs of LiFePO4 power batteries voltage and temperature parameter acquisition in real-time and accuracy requirements and reduce the wiring harness of detection system.A detection system of power batteries is designed in this paper,which is based on LTC6803 and NRF24L01,and has been carried on the experimental test. The system is mainly composed of the data transmitting end and data receiving end. The data transmitting end uses LTC6803 battery monitoring chip and digital temperature sensor DS18b20 to realize the accurate detection of battery voltage and temperature,the data receiving end uses PC software to complete the concentrated storage and management of data. Wireless communication between data transmitting end and the receiving end is accomplished through the NRF24L01 module.The experimental results show that the detection system has the advantages of reliable performance,convenient use,high measuring accuracy,fully meets the requirements of the use of industrial field,has a good practical effect.
