CONTROL METHOD TO PLURAL CHARGING DEVICES

摘要

PROBLEM TO BE SOLVED: To provide a control method to plural charging devices by which plural batteries can be charged at the lowest cost. SOLUTION: The plural charging devices are connected to a network to be controlled by a computer. The computer 10 receives charging information from each charging device when it makes charging (S20: Yes), and determines the optimum charging time based on the charging information (S32), and a parameter for the optimum charging time is transmitted to each charging device side (S34). Each charging device makes charging based on the transmitted parameter.
