question: how to get SOH?

Open df8oe opened this issue 2 years ago • 3 comments

Hi to all, I want to observe degradation Is it in the answer to "p.get_values()"? Possibly the difference of TotalCapacity and RemainingCapacity when StateOfCharge is 1.00? At my batteries the value of RemainingCapacity stays at TotalCapacity what I cannot believe...

Hi, That's a good question indeed. What number of cycles do you have ? My batteries have 1.5 years so I should be able to try but they're not charged at the moment ^^'. I'll try to report in the days to come. Cheers !

My batteries are 2 and 3 years old and have 412 / 440 cycles. It is not impossible that there is absolutely no degradation but is not very realistic I think... You should have access to SOH via RS232 console as I found on the web but I have not yet tried it.

The console command pwr replies State-of-Health (SOH) status as text, e.g. as Normal. pwrsys replies SOH status as percentage (also State-of-Charge (SOC) directly as percentage as well).
