Hi
I use bq20z65 in a 2 cell configuration and I realise one problem.
Shutdown Voltage has a minum value of 5000 mV.
CUV threshold has a default of 2200 mV.
During a discharge will the circuit when reaching 5000 mV go directly from delivering current to shutdown mode. (if not interrupted manually)
The circuit stays in shutdown mode until a charger is connected, when the circuit goes directly from shutdown to charge mode.
Relaxation mode is never entered, which I guess means that learning does not take place correctly.
Is the above correct? and how should this be handled?
(is manual interruption of discharge needed?, will some other mechanism make relaxation mode possible? Do I have to set CUV threshhold to a value well above 2500 mV forcing CUV before shutdown (Under some temperture and load conditions this means interrupting when still quite some energy is left in the cells)?)
Regards
