The main components of the 7KW charging station motherboard are as follows:

• Main control chip: As a core component, it is responsible for coordinating and controlling various functions

  of the charging station, such as identifying and matching electric vehicles, controlling the charging process

  according to vehicle needs, and exchanging data with other modules

• Power module: converts the input AC power into a stable DC voltage suitable for use in various circuits of the

  charging station, providing power support for the entire motherboard. It also has overvoltage, undervoltage

  and other protection functions to ensure the stability and safety of the power supply

• Communication module: realizes information exchange between the charging station and external devices.

  Common communication methods include CAN bus, Bluetooth, Wi Fi, 4G/5G, etc. Through these

  communication modules, the charging station can exchange data with the battery management system of

  electric vehicles, as well as communicate with the backend management system or user mobile app to

  achieve remote monitoring, fault alarm, charging reservation and other functions

• Measurement module:Accurately measure the power consumption during the charging process, provide a

  basis for billing, support different charging strategies and billing modes, and ensure accurate calculation of

  charging fees

• Security protection module:

  including over temperature protection, short circuit protection, overload

  protection, leakage protection, overcurrent protection and other circuits. Once an abnormal situation is

   detected, the circuit can be quickly cut off to protect the vehicle battery and charging station from damage,

  ensuring the safety and reliability of the charging process

• Protocol conversion chip:

  As different brands and models of electric vehicles may use different charging

  communication protocols, the role of the protocol conversion chip is to achieve conversion and

  compatibility between these protocols, so that the charging station can communicate normally with various

  vehicles
