By means of charge at off-peak and discharge at peak strategy, the profit from price difference of electricity at peak and off-peak can be obtained.

By continuously recording and analyzing users\' power consumption behaviors, reasonable charging and discharging strategy can be generated in combination with local electricity rate policies to reduce users\' peak power consumption, so as to achieve the purpose of reducing electricity fee.

The energy storage system discharges at the peak hour and reduces the rate of load change to achieve the purpose of smoothing load.

The cascade utilization of power batteries improves the overall economy of the energy storage system and maximizes the cycle life of used power lithium batteries
