EVSE Protocol Controller (EPC) is the intelligent part of the Charge charging stations. It is the communication to control the charging procedure of
electric vehicle ,and conforms to electric vehicle standard IEC61851 or SAEJ1772.Mounting onto standard rail according to DIN EN 60715
It is divided to cable version and socket version.
EVSE Protocol Controller

3.2 Function description
3.3.1 Charging process of controller with cable type (only CP signal is needed)
After switching on the working voltage, the module starts to initialize and perform the function self-test
(LED light flashes circularly), waiting for the car to connect. The controller waits for the charging cable to
connect to the vehicle (status a), and the LED flashes blue continuously. If the cable matching with the
controller has been connected (state B), the LED turns to stable blue light and turns on the electromagnetic
lock switch. After the gun head interlock, if the vehicle is in State C, the controller will make P1/ P2 in closed
state (connected state), and the LED will turn to stable green light. If status D (ventilation required) is displayed,
because the controller has no heat dissipation function, the controller makes P1 / P2 in the open state (off state)
and turns off the electromagnetic lock switch at the same time, the gun head interlock will be invalid, and the
controller will turn off the charging procedure, and the LED will turn into a stable red light.

Ventilation requirements
In the absence of ventilation, the risk of asphyxiation may be caused due to the accumulation of some battery
related gases when charging indoor. If the charging process is carried out indoor, forced ventilation shall be
installed, the charging pile controller does not have forced ventilation function.
Connection confirmation line (CS) current, resistance correspondence information.
current resistance/ current resistance/ current resistance / current resistance/ current resistance
32A 732Ω / 25A 536Ω / 20A 432Ω / 16A 348Ω / 10A 249Ω When the input resistance (minimum) is lower than 100Ω,
it cannot be charged or interlocked. The controller will reduce the current load to 7a within 5S, and the controller
will enter Status A until the resistance value of the input current rises.
