On the display on my CCGX it shows that the SOC is at 46% although the battery voltage is at 28,2 volts -which should be approximately 90-95%.
(I have checked the battery itself with an external voltmeter and get the same voltage: 28,2 volts )
How can I get the CCGX to show the right SOC %?
I have tried to open out the VE Configure after downloading it to my MAC but I cant find the program to open it (the .rvsc -file) . I would greatly appreciate help on how to get into the VE Configure on my MAC.
Do I need to use the VE Configure to solve my problem of SOC % ....or can I do something directly on the CCGX or maybe the VRM?
Could the problem of having 46% SOC be a result of the battery no beeing balanced?
Balancing / Equalization:
The battery is a Lithium Ion battery (approx. 10 kwh) from recycled electric car batteries (Mitsubishi Miev) - and have been working very well since I got the system a year ago.
The maximum voltage should be 28,7 volts for balancing....but now it goes to float at 28,2 volts. The highest battery voltage (in overall history in the CCGX) according to the MPPT (150/70) is 28,67-so maybe the issue here is that the cells have not been balanced?
I have chosen "Equalization" on the CCGX under Advanced...and it shows: "Starting..." . The battery in at 28,2 volts as mentioned -when will the equalization (balancing) start? And it seem that if I go to another menu on the CCGX the equalization stops....-is that right? Do I need to leave the display of "Starting..." to remain in order for it to equalize ?
I would be very happy for help on this :-)
