Lithium-ion battery charger and adapter are different

Lithium-ion battery chargers should have current and voltage control results that are suitable for battery charging, so that they can be fully charged and then blocked after floating. The basic components of lithium-ion battery chargers and other rechargeable battery chargers are communicative, consisting of three parts: 1, housing, 2, input/output line, 3, circuit board, heat sink, and various electronic components. In principle, it is composed of a constant power supply plus necessary control circuits such as constant current, voltage limit, and time limit. Adapters usually only supply 5V or hundreds of mA of DC power, and must be charged with a common charging control circuit (such as a mobile phone). The adapter can be an independent hardware interface device or an information interface. The adapters used generally include power adapters, USB and serial port adapters, etc. The important result of the adapter is voltage stabilization, which is generally composed of a housing, a power transformer and a rectifier circuit. It is suitable for power supply transfer equipment of small portable electronic equipment and electronic appliances. It is a kind of ancillary equipment, which is widely used in audio-visual machines, game consoles, language repeaters, etc. It can be seen that the lithium-ion battery charger includes the results of the adapter, because it has one more control circuit than the adapter. For example, the mobile phone charger includes three stages of constant current, constant voltage, and trickle charging. This is caused by the charger itself. The design choice, and the charging control of the notebook computer is in the computer body, the adapter only serves the purpose of voltage stabilization, and does not have the constant current and voltage limiting design of the above-mentioned charger.
