The difference between lithium-ion battery, battery charger and adapter. Lithium-ion batteries, battery chargers should have a current and voltage control function in line with the battery charging, and can be fully charged after the float charge and then closed. Adapter usually just supply DC power of about 5V hundreds of mA, to be able to charge with the charging control circuit (such as cell phones). Charger is specialized, adapter generally refers to the power supply.
The difference between lithium-ion battery charger and adapter
Adapter: is an interface transferor, that is, an adapter. The use of adapters one is to have the purpose of voltage stabilization, in other words, it is the AC / DC power stabilization into the power equipment, during which there is no power storage, once there is no AC / DC power, the adapter will not be able to effectively make the power equipment to get the power; the second is to serve as a built-in power supply or external power supply.
Power adapter is a small portable electronic equipment and electronic appliances power supply power conversion equipment, it puts the power supply external, with a line and the host connection, so that can reduce the size and weight of the host, but a very small number of equipment and electrical appliances to the power supply built into the host. It is composed of internal power transformers and rectifier circuits, according to its output type can be divided into AC output type and DC output type; according to the connection can be divided into wall-plug type and desktop type. There is a nameplate on the power adapter, which indicates the power, input and output voltage and power flow and other indicators, pay special attention to the input voltage range.
The important function of the adapter is to stabilize the voltage, generally by the shell, power transformer and rectifier circuit. Apply to small portable electronic equipment and electronic appliances power supply power conversion equipment. It is a subordinate supporting equipment, commonly used in sub-master machine, game machine, speech repeater, etc..
Charger: is a kind of alternating current will be converted to low-voltage direct current equipment, in the battery for the work of the power supply or standby power occasions, the charger has a wide range of prospects for use. There are many ways to categorize chargers. The most common is divided into: advanced business charger, seat charger, USB charger, car charger and so on. Another common is divided by raw materials: lead-acid battery chargers, nickel-cadmium / nickel-metal hydride chargers, lithium-ion battery chargers.
The basic composition of lithium-ion battery charger and other rechargeable battery charger is the same, which is composed of three parts: shell, input/output line, circuit board, heat sink, and various electronic components. In principle, it is composed of a stabilized power supply plus the necessary control circuits such as constant current, voltage limiting and time limiting.
● The biggest difference between a charger and an adapter is that a charger only charges the battery, while an adapter not only charges the battery, but also supplies power to the host computer.
●Lithium-ion battery charger is included in the power adapter function, because it has one more control circuit than the adapter, such as the cell phone charger includes constant current, constant voltage, trickle charging three phases, which is determined by the charger's own design, while the charging control of the laptop computer is in the computer body, the adapter is only for voltage regulating purposes, and does not have the constant current and voltage limiting design that the above charger has.
● Lithium-ion battery chargers have current and voltage control functions in line with battery charging, and are able to fully charge and then float and close.
●Adapters usually only supply DC power of about 5V and a few hundred mA, and can only be charged in conjunction with a charge control circuit (such as a cell phone).
It can be seen that the charger is included in the adapter function, because it is more than the adapter has a control circuit, such as cell phone charger includes constant current, constant voltage, trickle charging three phases, which is determined by the charger's own design, and the laptop's charging control is in the computer body, the adapter is only play a regulator purpose, and not the above mentioned charger has a constant current and voltage-limiting design.
