Battery Charger
As batteries are now used at more diverse applications, such as e-bike, e-scooters, power tools, vacuum cleaners and small home appliance, there are requirements to charge various batteries for each applications. A battery charger provides direct current to the battery to restore the used-up electrolyte. Battery charger applications require high efficiency, fast charging, low stand-by power consumption and CC/CV operation.
