Manufacturers : Batteries : Battery chargers
Rechargeable batteries are widely used in a lot of portable or mobile electrical and electronic devices or appliances such as, cellular phones or cordless telephones, remote repeaters, remote control units, remote sensors, portable lighting devices, portable radios, portable drills and many other devices. These batteries need to be routinely charged. A battery charger is a power supply with controllable voltage and current limits. Battery chargers are often provided as either internal or external devices to be used to recharge these batteries. To charge the battery, the battery terminals are connected to the charger terminals to connect the battery cells to the charging circuit, and the charging circuit is connected to a power source to selectively supply power to the battery cell to charge the battery cell. Chargers are commonly divided into uncontrolled and controlled chargers. The simplest uncontrolled charger consists of a low frequency power transformer along with an uncontrolled bridge rectifier. Controlled chargers offer the ability to control the charging current as well as to implement both constant-voltage and constant-current charging methods. Controlled battery chargers can be classified into two general groups; linear regulator battery chargers and switching regulator battery chargers. Conventional linear regulator battery chargers typically employ single stage charge control with hardware-based voltage regulation. The external current limit circuit generally requires tight voltage regulation to ensure that the current is limited to below a level that could damage the battery. Switch mode power supply (SMPS) based chargers offer offer high efficiency power conversion due to high frequency operation. The high frequency power conversion stage results in significant size reduction for the energy storage elements (transformers, inductors, and capacitors).
