The difference between lithium -ion battery, battery charger and adapter. Lithium -ion battery and battery charger should have the current and voltage control function that conforms to the battery charging, which can be fully charged and closed and closed. The adapter usually only supplies a DC power supply of hundreds of MAs about 5V, and it must be charged with the charging control circuit (such as a mobile phone). The charger is dedicated, and the adapter generally refers to the power supply.
The difference between lithium ion battery charger and adapter
Adapter: It is an interface transferor, that is, a rotor. The use of the adapter is the purpose of stabilizing. Obtain power; the second is as a built -in power supply or external power supply.
The power adapter is a small portable electronic equipment and electronic appliances supply power supply transformation equipment. It connects the power supply outside the power supply. This can reduce the volume and weight of the host. Inside. It is composed of a power transformer and a rectifier circuit. According to its output type, it can be divided into AC output and DC output types; it can be divided into wall and desktop type according to the connection method. There is a nameplate on the power adapter, which indicates the power, the input output voltage and the current indicators are marked. In particular, pay attention to the range of the input voltage.
The important function of the adapter is stabilization, which is generally composed of cases, power transformers and rectifier circuits. Suitable for small portable electronic equipment and electronic appliances power supply transformation equipment. It is a kind of supporting equipment, which is generally used in children's machines, game consoles, and speech repeat machines.
Charger: It is a device that converts AC power to low -voltage DC power. In the case of electricity consumption with battery as a working power supply or backup power supply, the charger has a wide range of prospects. There are many ways to classify the charger. The most common is to be divided into: high -end business charging, seat charger, USB charger, car charger, etc. Another common is divided into: lead -acid battery charger, nickel -cadmium/nickel -metal hydride charger, lithium -ion battery charger.
The basic composition of the lithium -ion battery charger and other charging battery chargers are the same. It consists of three parts: shell, input/output cable, circuit board, heat sink, and various electronic components. In principle, it is composed of a stable power supply plus the necessary constant current, voltage limit, and time -limited control circuit.
● The biggest difference between the charger and the adapter is that: the charger is only charging the battery, and the adapter can not only charge the battery, but also supply the host;
● Lithium -ion battery charger includes the function of the power adapter, because it has one more control circuit than the adapter, such as the mobile phone charger includes three stages: constant flow, constant voltage, and trickle charging. This is determined by the design of the charger itself. The charging control of the laptop computer is in the computer, and the adapter only plays a voltage, and does not have the constant current and voltage limit design of the above charger.
● Lithium -ion battery charger has the current and voltage control function that conforms to the battery charging, which can be fully charged and closed and closed.
● The adapter usually only supplies DC power supply with hundreds of MAs around 5V. It must be charged with the charging control circuit (such as mobile phones).
It can be seen that the charger includes the adapter function, because it has one more control circuit than the appointed inner accessories. For example, the mobile phone charger includes three stages: constant flow, constant voltage, and trickle charging. The charging control of the laptop is in the computer, and the adapter only plays a voltage for voltage, and does not have the constant current and pressure -limiting design of the above charger.
