Although battery-swapping operation at the charging and swapping station for vehicles is entering the automation and intelligence process, many other issues are yet to be paid attention, such as operation standardization, battery-swapping record data missing and the battery-swapping record data inaccuracy. Based on the above background, this paper designs and implements a battery-swapping operation control unit between monitoring system and charging machine. The battery-swapping operation control unit is equipped with an independent CPU, and can communicate with monitoring system and battery-swapping robot through the internet, which can finish the whole process of battery-swapping on its own and also has the functions of manual setting and adjusting the battery-swapping parameters and records. Meanwhile, this design furnishes two independent communication channels for the charging system, thus the stability of battery-swapping is enhanced. Experiment in the battery-swapping station shows that, this unit can simplify the operation standardization and enhance the safety of battery-swapping, and it can also ensure the safety of the battery-swapping records, thus can improve the operation efficiency of the battery-swapping station.
