 Controller Features

The EKEPC2-C/S controller is a kind of product suitable for charging pile of electric vehicle.
1)Software correction instructions,such as EKEPC2
2)Maximum charging capacity indication 10A,16A,20A,25A,32A or 6A,8A,10A,13A,16AThrough the
internal dial switch (The factory default setting is 32A).
3)"C"for the cable version and"S"for the socket (without cable)version

Select controller additional functions:
Switch the DIP switch to "ON"which corresponding to the functions you need

The functions of the corresponding positions are described as
follows:In the "ON"position
1:Open LCD display function,have to connected a LCD Screen 
2:Open Dynamic Load Balance Working Mode,have to connected a
DLB current monitoring device,a RS485 communication kWH meter or Current Transformer(CT only working for single phase)
3:Socket version working mode
4:Open Function with RFID,have to connected a RFID module and RFID card
5:Open Function with Electronic Lock,should connected to a electronic lock
6:Open Function with DC6mA leakage  current protection,should connected to a RCMU
The functions of the corresponding positions are described as follows:
In the "OFF"position
1:No need for LCD Screen
2:No need for DLB function
3:Cable version working mode
4:No need for RFID function
5:No need for electronic lock function
6:No need for RCMU(DC6mA protection )function















 EKEPC2 -C/S EVSE Controller Application Case.

The following is a schematic diagram of an application case.



EKEPC2-C/S EVSE Protocol  Controller connection status

EKEPC2-C/S EV Charge Controller RS485 communication description
Modbus communication protocol, baud rate: 9600, 8, n, 1 Address: 1-255 Default: 255 (broadcast address)

Note: 1) Register address: 90-95 register value is: a) =65535, this time the address is invalid, all data will be in accordance with the controller set value to display and judge. b) = When the external communication address is 1, the controller will read the corresponding value in the meter. See Table 1 below

If the DLB function is enabled and register 96 data is a) =65535, the controller will read the sampling value of the external current transformer. b) = Register number of current value in the ammeter with external communication address 2, the controller will read the current value in the ammeter. See Table 1 below

EKEPC2-C/S Communication Message Example:DLB Maximum Current Change
 

Change the maximum current set in DLB to 60.00A (6000) and register address number to 102(66H):

The upper computer sends: FF 06 00 66 17 70 72 1F

Address + Function code + start address number high level + Start address number low level + data high level + data low level +CRC check

Controller replies: FF 06 00 66 17 70 72 1F

Address + Function code + start address number high level + Start address number low level + data high level + data low level +CRC check

3.2  Read the device SN (2022010158-- 7885 6D2E) :

Upper computer send: FF 03 00 76 00 02 30 0F
