Introduction to lithium battery charger
Lithium battery charger usually refers to a device that converts AC power into low-voltage DC power. It includes control circuits such as current limiting and voltage limiting that meet charging characteristics. Lithium battery chargers are widely used in various fields, especially in the field of life, they are widely used in common electrical appliances such as mobile phones and cameras.
Lithium battery chargers are widely used in various fields, especially in the field of life, they are widely used in common electrical appliances such as electric vehicles, flashlights, new energy vehicles and UPS power supplies. It generally charges the battery directly without any intermediary equipment and devices.
Introduction to power adapter
The common power adapters on the power adapter market are power converters that have undergone voltage transformation, rectification and voltage stabilization. The output is DC, which can be understood as a low-voltage regulated power supply when the power is met. It is widely used in telephone handsets, game consoles, language repeaters, walkmans, notebooks, cellular phones and other devices.
Power adapters are widely used in routers, telephone handsets, game consoles, language repeaters, walkmans, notebooks, mobile phones and other devices. Most power adapters can automatically detect 100-240V AC (50/60Hz).
Function
Lithium battery chargers should have current and voltage control functions that meet battery charging requirements, and can float charge and then shut down after fully charged. Adapters usually only provide a DC power supply of about 5V and hundreds of mA, and can only be charged with a charging control circuit (such as a mobile phone).
Lithium battery chargers include the functions of adapters, but there are also constant current, constant voltage and other control circuits inside the charger that meet the charging characteristics. The charging control circuit of the adapter is generally completed on the host. For example, lithium battery chargers and laptop chargers are actually just power adapters. They do not include charging control circuits inside, and charging control is completed inside the computer.
The difference between a lithium battery charger and a power adapter
The biggest difference between a charger and an adapter is that a charger only charges the battery, while an adapter can not only charge the battery but also power the host;
A lithium battery charger includes the function of a power adapter, because it has one more control circuit than an adapter. For example, a mobile phone charger includes three stages: constant current, constant voltage, and trickle charge, which is determined by the charger's own design. The charging control of a laptop is inside the computer, and the adapter only plays a role in voltage stabilization, without the constant current and voltage limiting design of the above chargers.
