I then red CAN protocol and selected options for my charger.

https://leafdriveblog.files.wordpress.com/2018/11/eltek_canbus_protocol.pdf

For CAN protocol uses standard ID. General ID required to command charger is

ID 02 FF

Data string to command charger is

''01 E8 03 6E 0F 3C 00''

01 for enable

E8 03 for the max power range 0 to 1000 decimal, 1000=100%, so 0000 to 03E8 in hexa but reversed

''6E 0F'' max voltage same coding as power. I suppose that for 385V send 0A 0F

''3C 00'' max current same coding as power. For 1 amp send 10 decimal so 00 0A hex in reverse so 0A 00

Rest of calculations:

214V is 5C 08

385V is 0A 0F

390V is 3C 0F

392V is 50 0F

395V is 6E 0F

400V is A0 0F

410V is 04 10

415V is 36 10

420V is 68 10

12A is 78 00

10A is 64 00

8A is 50 00

6A is 3C 00

5A is 32 00

Messages are transmitted at 800ms interval.

'''Eltek Valere IP20 charger 3kW''' is also well documented

https://www.rec-bms.com/datasheet/EltekGuideIP20.pdf

This protocol is for IP20 chargers meant for installation into racks. I confirmed wiring color was ok. I connected DC output to my test battery and AC to my socket.

I connected CAN wires as per document and i got good CAN return report with chargers serial no. <nowiki>https://www.rec-bms.com/datasheet/EVPowerchargerCANprotocol.pdf</nowiki>

After i was sure everything was as it supposed to be i commanded the 02FF telegram that i described in previous Volvo charger

Msg ID 02 FF Data string to command charger is: ''01 E8 03 6E 0F 3C 00''

-01 for enable, E8 03 for the max power range 0 to 1000 decimal, 1000=100%, so 0000 to 03E8 in hexa but reversed, 6E 0F max voltage 395V same coding as power, hex value x 10, 3C max current same coding as power. For 1 amp send 10 decimal so 00 0A hex in reverse so 0A 00.

* Voltage
* 214V is 5C 08
* 385V is 0A 0F
* 390V is 3C 0F
* 392V is 50 0F
* 395V is 6E 0F
* 400V is A0 0F
* 410V is 04 10
* 415V is 36 10
* 420V is 68 10

* Current
* 12A is 78 00
* 10A is 64 00
* 8A is 50 00
* 6A is 3C 00
* 5A is 32 00

This time 02FF telegram needs repeating at '''100ms''' for the charger to keep alive!

Charger returns with status messages 0305 and 0306 which repeats in 800ms intervals.

* ID 0305
* B0 DCCurrent1
* B1 DCCurrent2
* B2 DCVolt1
* B3 DCVolt2
* B4 power1
* B5 power2
* B6 status

* ID 0306
* B0 DCPower %
* B1 ACPower1
* B2 ACPower2
* B3 ACVoltage1
* B4 ACVoltage2
* B5 Temp secondary
* B6 Temp primary
