What is the main board of the communication charging station made of? Understanding Control, Measurement, Communication, and Safety in One Text

The motherboard of the communication charging station is the "brain" of the charging station, which does four things well: controlling the charging process, measuring electricity bills, communicating with the backend, and ensuring safety.

Control the charging process

• After inserting the gun, check the CP signal and confirm that the vehicle is connected normally. Close the relay to power on.

• Real time monitoring of voltage and current during charging, disconnecting the relay after being fully charged or receiving a stop command.

• 7kW pile single-phase control, 22kW pile three-phase independent control, each phase relay can be independently turned on and off to cope with unbalanced loads.

Measuring electricity bills

• After sampling voltage and current, calculate power and electricity with an accuracy of ± 2% or higher according to the national standard, and the operating pile requires ± 0.5%.

• Measurement data is stored locally and reported to the backend for settlement through OCPP.

• Some motherboards use independent energy meters, while others use onboard metering chips, which have lower costs but slightly weaker long-term stability.

Communicate with the backend

• 4G/WiFi/Ethernet access operator platform, OCPP protocol uploads charging status, metering data, fault information, receives remote start stop, rate update, firmware upgrade instructions.

• Local cache data during communication interruption, and batch retransmission after recovery.

ensure safety

• Overvoltage, undervoltage, overcurrent, leakage, overtemperature, insulation drop, emergency stop, immediately disconnect the relay in case of any abnormality.

• Leakage protection 30mA action, insulation resistance below threshold alarm shutdown, emergency stop button hard circuit physical power-off.

• Partial motherboards are equipped with CP signal anomaly detection, relay adhesion monitoring, and lightning surge protection.

Priority of four things

• Safety is the bottom line, and in any situation, prioritize the protection of human life and equipment.

• Control is the duty, capable of being charged, disconnected, and not malfunctioning.

• Measurement is credit, and only by accurately calculating electricity bills can we continue to operate. Communication is value-added, it can be charged even without it, only with it can it be managed.

in a word:

The motherboard does not directly generate current, but determines whether the current can flow safely, accurately, and controllably to the battery, and turns the entire process into data that can be billed, managed, and optimized.
