Method and apparatus performing charging modulation

A charging pole power management system for performing a charging modulation between one or more charging poles, a local power system and a global power system, comprising:

• the one or more charging poles;
• one or more measuring devices, respectively disposed to one or more cut-off points of a power grid corresponding to the one or more charging poles, the local power system and the global power system;
• one or more control units, connected to the global power system, the local power system, a customer management system, the one or more charging poles, and the one or more measuring devices via corresponding networks,
• wherein each of the one or more control units comprises a processor configured to execute machine instructions to implement a computer implemented method, the method comprising:
• receiving monitoring data from the one or more measuring devices;
• receiving first controlling data from the global power system, second controlling data from the local power system, third controlling data from the customer management system, and fourth controlling data from the one or more charging poles;
• identifying one or more measuring values corresponding to three phases of three phase power system according to the monitoring data;
• adjusting a charge level of a target phase of a target charging electricity by determining whether a target measuring value of the target phase of the target charging electricity exceeds an allowed charging range according to the one or more measuring values, wherein an electric vehicle is charged via a target charging pole providing the target charging electricity;
• and
• determining whether to power-off or power-on the target phase of the provided target charging electricity according to current charge level of the target phase.
