Abstract

In this work, the actual working characteristics of on-board energy storage devices under complex driving conditions based on big data of new energy vehicle operation are explored. Studies were conducted on the distribution characteristics of vehicle speed and acceleration. Additionally, further examination was carried out on the corresponding current, voltage, temperature characteristics, power, and SOC variation characteristics of energy storage devices. The results show that for conditions of driving speed in the range of 0~70km/h and acceleration fluctuating between -1m/s2 and 1m/s2, the working current of the vehicle energy storage device is generally between -80A and 100A, and can reach above 110A at some points. The braking energy recovery rate is about 37.38%.
