worn out batteries.
Connect Qulon-12m (with K=1) to each battery of the
group and write down the estimated capacity. Find the maxi-
mum estimated capacity for the group E
max
, then calculate
calibration coefficient for your battery according to formula:
К
= E
n
/E
max
,
where: E
n
– nominal battery capacity or capacity less
then nominal, appointed in view of deterioration of batteries.
7.5. Method of battery history
The method of battery history is used during sched-
uled service of individual battery, if carrying out the measured
discharge is impossible or inconvenient. The method is based
on the assumption, that in the beginning of the battery service
life (right after the first connection of Qulon-12m to the bat-
tery), the capacity of the battery is accepted known (for ex-
ample, it is considered that it is equal to nominal capacity).
During further service battery capacity estimated by Qulon-
12m is compared to this value.
Connect Qulon-12m (with K=1) to the battery and write
down the estimated capacity E
m1
, then calculate calibration
coefficient for your battery according to formula:
К
= E
n
/E
1
,
where: E
n
– nominal battery capacity or capacity less then
nominal, appointed in view of deterioration of the battery.
