7.3. Method of average
The method of average is used if making measured
discharge is impossible or inconvenient. This method is
based on the assumption, that batteries to be tested are part
of some group (for example, intended for connection in the
battery system or already connected in the battery system)
and on the average have known capacity (in the elementary
case - nominal capacity). This method is recommended for
use with the new or poorly worn out batteries.
Connect Qulon-12m (with K=1) to each battery of the
group and write down the estimated capacity. Calculate the
average estimated capacity for the group E
av
then calculate
calibration coefficient for your battery according to formula:
К
= E
n
/E
av
,
where: E
n
– nominal battery capacity or capacity less
then nominal, appointed in view of deterioration of batteries.
7.4. Method of maximum
The method of maximum is applied, if carrying out the
measured discharge is impossible or inconvenient. It is based
on the assumption, that in the group of testing batteries (for
example, intended for connection in the battery system or
already connected in the battery system) the least worn out
battery has known capacity (in the elementary case - nominal
capacity).
This method is recommended for use with the
