HANGCHA CPD30-A - Daily charging, Equilibrium Charge, Complementarity Charge, Charge for long-term storage

Daily charging
– The battery that has been made the first
charging and used regular, then charged
again, is named daily charging.
– Its way is almost same as the first
charging.
– The recharging value is 1.2 times than the
last electric discharging. But the
electric-change for new battery‟s fore five
times should be 1.5 times than the last
electric discharging.
– During any charge, the temperature of
electrode should not be exceeded 45
0
C，
otherwise it should be taken measures
such as reducing artificially charging
current or lowing the temperature. If the
temperature doesn‟t drop, you should
stop charging, till the temperature
dropping down.

Adopt intelligent charging for the daily
charging. The first five charging should using
Equilibrium Charge according to the intelligent
charger operate manual.
Equilibrium Charge
– During using of the battery, it often occur
disequilibrium among the voltage, the
density and the capacity.
– Compared to most of the batteries , often
finds that single battery‟s proportion of
voltage and electrolyte rises slowly during
the course of charge and during the
course of discharge, its battery‟s
proportion of voltage and electrolyte
declines faster than most of other
batteries.
– Make equilibrium charge in the following
case：
a. Discharge voltage often drop down
ending voltage；
b. Discharge current is often larger；
c. Not charge in time after discharge
d. The electrolyte is mixed with impurity
with a little harm.
e. It often be charged deficient or has not
been used for a long time；
f. After taking out the battery group for
checking or cleaning settling.
The method of Equilibrium Charge：
– Firstly, charge the battery normally, and
then rest for 1 hour after the end of
charge.
– Charge it again with the current belongs
to the second normally charge until the
electrolyte gives off a large number of
bubbles, then stop charging for 1 hour.
– Repeat it several times as mentioned
above until the voltage and the density
keep invariable and the battery gives off a
large number of bubbles immediately
when charge again.
Complementarity Charge
– If one day‟s work cannot be fulfilled with
one charge, carry out opportunity charge
during breaks.
– When the temperature of circumstance is
low, carry out opportunity charge.
Charge for long-term storage
– Carry out equilibrium charge before
storing.
