4. Charging Request
4.1
Equalization Charging
Equalization charging should be carried out in the following situation:
a. There are more than two batteries which voltage is under 13.0V in one group.
b. More than three months after floating operation.
Equalization charging is recommended as follows:
Charge the battery group with constant current not exceeding 0.1C
10
A till the
average voltage increases to 14.1V/block(25º
C)
,
then change into constant
voltage of 14.1V/block charging. The equalization charging time should be 24
hours.
4.2
Battery Charging
Battery Charging should be carried out in the following situation:
a.
The batteries should be recharged in time after discharge.
b.
After battery system is installed.
c.
Battery storage period exceeding three months or open circuit voltage lower
than 12.6V/block.
Battery charging is recommended as follows:
The batteries should first be charged on the constant current of 0.10C
10
A till the
average voltage of the batteries increases to 14.1V, then the batteries should be
charged with constant voltage of 14.1V till the charging has completed.
On some occasions, the batteries have to be fully charged immediately, then fast
charging could be adopted. The value of limit current should not be larger than
0.2C
10
A, and the charge voltage should be 14.1V/block(25º
C).
We can determine if the batteries are fully charged by one of following two
conditions:
a. After charging 18
~
24hours. The charging time will be lesser if it is not deep
discharged. For example at 20% DOD (refer to Table 2-1 for the Depth of
Discharge vs Charging Time), the charging time can be shorten to 10 hours.
b. Under the condition of constant voltage, the value of charge current has no
variation for continuously three hours.
5. Storage
All gel batteries experience self-discharge in open circuit. The result is that the
voltage of open circuit is decreased, and the capacity also decreases. Please note the
