A battery charger is a device which is used for transferring energy into a rechargeable battery by passing an electric current through it. Some battery chargers need to be manually disconnected by the constant voltage source whereas others may use a timer for cutting off the power at fixed intervals. Currently, the expansion of the electronics industry is the primary factor catalysing the demand for battery chargers. An increasing demand for electrical vehicles (EVs) and connected devices acts as another major force stimulating the growth of the battery charger market.
