Elcon 3kW cuts out after 1 hour
Posted: Thu, 12 Jul 2018, 15:15
Hi folks,
My 3kw Elcon charger has continued to work since I replaced a blown capacitor in it. It was a new unit that I had trouble with Elcon not doing a repair on (long story). Anyway, I ended up with the thing in a bricked state. I dug around in the potting where it was all blacked and found the blown cap. It works well now (20amps) and does all the right things except that it cuts out after exactly 1 hour. I can restart it immediately by toggling the “Charge sense” on the BMS. It does everything else correctly.
It is not hot, it charges at 20A and it cuts out when the BMS says to. I never get to the full pack V because of imbalance in the cells, which I am working on. In every other sense it works fine.
The only clue I have is that someone suggested that the RRGG blinks on the indicator when the AC power comes on means that it has a comms error. It is only using a “Charge Enable”, not the CAN comms though so I don’t know what is going on.
Does anyone have any ideas?
Thanks,
Paul
