Circuitry Functions;
The functions described below are for safety purposes and are not meant to function on a regular
basis. These should only active upon failure to charge or discharge the pack properly.
Over-Charge:
The control circuit monitors each cell voltage in the battery pack. If any cell voltage is
greater than 4.35V the internal switch (MOSFET) in the control circuit opens to stop
further charging. This will be reset when the pack is discharged.
Discharge:
Shorting:
Fuses:
Balancing:
R
The control circuit monitors each cell voltage in the battery pack. If any cell voltage is
less than 2.5V the internal switch (MOSFET) in the control circuit opens to stop further
discharging. Charging the pack will increase the voltage of this cell and reset the
circuitry, allowing discharge again.
If the pack output is shorted (> 50A), the pack circuitry will shutdown the excess current,
by opening the MOSFET switch device in the circuitry. This will reset when a charge is
applied to the pack.
A separate fuse is supplied to as a backup overcurrent limiter. The 30 A fuse protects
the pack from excessive loads or short circuits.
In the event that a cell is over-charged in the pack and its voltage becomes too great, a
circuit will discharge that one cell back to within its correct operating voltage range.
This will help extend the life of the battery pack.
