Float cum boost battery chargers or FCB Chargers, are a single rectifier or converter for AC to DC conversion. However, for the higher-load FCB chargers, one may find double rectifiers. One rectifier feeds the load, while the other is used for battery charging.
More About FCB Chargers:
Like the technical setup, the operation of the battery charger is fascinating as well. The three-phase AC Voltage is fed to a suitably rated step-down double-wound transformer. The procedure is done via a suitably rated MCB. The secondary voltage, on the other hand, is fed to a 3-phase full wave control thyristor bridge. All these components are necessary to ensure a smooth charging operation.
How do FCB Battery Chargers Optimize Energy Efficiency?
When talking about the energy efficiency of float cum boost chargers in India, we cannot forget the charging procedure. It is a process which plays a major role in storing energy. We discuss more about this below:
- Boost Charging: It is a charging process where the battery gets fully charged from a discharged condition. A constant current process is the key operational feature here. It causes efficient charging. During the boost charging procedure, the battery’s voltage varies from 1.85V/cell to 2.75V/cell. The point at 2.35V/cell is also known as the gassing point. It is named so because the process of gassing starts at this point. After this point, the charging current must be restricted to a certain limit.
- Trickle/Float Charging: In this charging process, the battery is charged at a constant voltage. This is done to compensate for the local discharge. The voltage needs to be maintained at 2.25V/cell for trickle charging. In the case of float charging, one should follow a voltage of 2.23V/cell.
As one can assume, these two charging procedures greatly save energy. The FCB Chargers have both auto and manual charging, which makes the process efficient and reliable. The triggering of the thyristors is controlled by an electronic voltage or current regulator unit. The feedback signals are suitably processed and compared with the reference generated in the control unit.
