Difference between li ion battery charger and power adapter

The adaptor

The adapter is an interface translator. The use of adapters has the effect of stabilizing pressure,in other words, the AC / DC electrical stability into electrical equipment, there are no electricity storage, once there is no AC / DC adapter, can effectively make the electricity equipment consumption; and also as a built-in power source or external power supply.

The main function of the adapter is voltage stabilizer, which is usually made up of the shell, power transformer and rectifying circuit. It is suitable for the power supply conversion equipment that for small portable electronic equipment and electronic appliances. It is a subsidiary equipment, widely used in the mother machine, game machine, language reading machine and so on.

The li ion battery charger

Charger is a device that converts alternating current into low voltage direct current. When battery is used as a power supply or standby power, the charger has wide application prospects. There are many kinds of classifications for chargers. The most common is to be divided by using: advanced business charge, seat charger, USB charger, car charger and so on. The other is divided into lead-acid battery charger, nickel cadmium / nimh battery charger, li ion battery charger according to the raw material.

The basic composition of li ion battery charger and other rechargeable battery charger is the same. It consists of shell, input / output line, circuit board, radiator, and all kinds of electronic components. In principle, it is composed of a stable power supply plus necessary constant current, limit pressure, time limit and other control circuits.

Thus, the charger includes the function of adapter, because it is a multi adapter control circuit, such as mobile phone charger includes constant current, constant voltage and trickle charge, which is decided by the design of the charger, while charging control of notebook computer is in the brain in vivo, but adapter can only play the role of regulator, without constant current and voltage limiting that designed for the li ion battery charger.
