Abstract :
In order to solve the problem of real-time and accuracy for collecting the traction battery evaluation parameters, including battery voltage, battery current and battery temperature, the data acquisition system based on Field Programmable Gate Array(FPGA) and Universal Serial Bus Protocol (USB2.0) is designed. In this paper, FPGA is used as the microcontroller to control analog to digital (A/D) conversion and USB transmission. Moreover, USB firmware and driver program are explored and achieved. Validation experimental results show that the designed system is high credible. It also shows that the accuracy and speed of data sampling are improved. It is great benefit to evaluate battery status in battery management system.
