In battery backup mode operation, when the AC input voltage is outside specified tolerances for the UPS or the utility power fails, the inverter and the battery step in to ensure a continuous supply of power to the load following a very short less than 10 ms transfer ...
How Does a Battery Charger Work?
What is the principle behind the operation of a battery charger? A battery charger works by providing a direct current (DC) to a rechargeable battery in order to restore its energy. The charger converts the alternating current (AC) from a power outlet into DC, which is then used to charge the battery.

Battery Balancing Techniques
Overview and Operation Principle The charge levels in a multi-cell battery pack are equalized with the assistance of a latest method i.e., Active Battery Balancing. In contrast to passive balancing, where extra energy is simply depleted as heat, active balancing tries to redisperse this extra energy to other cells in the pack that need charging.
