System
The lithium-ion battery pack is fitted with BMS, a system which monitors
the voltage in each individual battery cell. A combined battery sensor/
balancing unit is fitted to the top of each cell.
The PCB is fitted directly onto the cell's + and - terminals and has two
functions:
1. The board constantly monitors cell voltage so that it remains within
the permitted range (2.6-4 V). If voltage is within the permitted
range, a green diode lamp lights up, The unit's output signals to the
main monitoring system that everything is in good working order.
2. The unit also helps to balance the cells while the battery pack is
recharging. When the charge voltage exceeds 3.6 V, the unit starts
to deduct balancing energy from + to - , increasing to 1 ampere
when maximum voltage (4.0 CV) is achieved. When the PCB is
balancing (deducting power), a red diode lamp lights up (at the same
time as the green one). The red diode lamp on the sensors does not
signal that there is an error.

The PCB outputs are daisy chained and monitored by a
micro-controller-based (MCU) monitoring system.
