BATTERY CHECK
The lithium-ion battery of KIDS10/12 has an integrated electronic energy
management, different from lead batteries that work without electronic control. This means
that the charging and discharging battery drivers are independent from each other being
able to have supply voltage in only one of them and not in the other.
During normal functioning there must always be supply voltage in the loading port
while the tension of the discharge port is 0V at the time when the battery is fully charged
and it stays like this until the battery is charged above the minimum limit.
There are some checks that can be done in case you think that the battery might not
work correctly.
Checking the battery voltage: Although the battery's nominal voltage is 48V it should
reach 54.6V by the end of the charging process. If at the end of charging the battery
remains below this value it is an indication that there is an internal battery error. Usually this
error occurs with the fact that the LED indicator of the charger changes the colour from red
to blue instead of to green. A third check is to measure the voltage at the charging and
discharging ports. With the values obtained consult the following table:
BATTERY STATES
Voltage at charging port Voltage at discharging port State
36V
– 54.6V (equal to
discharging port)
