21700 battery

21700 lithium battery pack application range



1. Used for motorcycle battery power supply.

Used for motorcycle battery power supply, mainly used for various batteries, such as portable batteries, power batteries, micro batteries, small lithium batteries, intelligent batteries, etc. Among them, the portable battery is small in size, light in weight, fast in charge and discharge, and can supply power to multiple single cells in direct series and parallel connection. For electric vehicles that require centralized management of charging, a small lithium battery pack can be installed on the positive and negative pole boxes of the power battery, and directly connected to the charging device to provide constant battery power for electric vehicles.

2. Vehicle battery energy storage system.

It mainly refers to the energy storage room used to store electrical energy in the vehicle battery. Vehicle-mounted batteries have the advantages of small size, light weight, large capacity, safety and reliability, etc., especially for mini-car batteries, which are more widely used. This type of battery can directly store electrical energy in the on-board battery, and can convert electrical energy into mechanical energy (such as driving a generator to start the vehicle) or provide electrical energy to the vehicle when the vehicle needs it. The system mainly includes vehicle battery, intelligent temperature control system and fault alarm system, and generally can be divided into two parts: energy storage group and inverter group. The intelligent temperature control system consists of two parts: temperature sensing element and heating element; fault alarm system includes: early warning, diagnostic control device and alarm information display, etc.

3. Lithium batteries for energy storage, supercapacitors, lead-acid batteries and other products can be used to provide DC charging and discharging support for batteries.

The safety, stability, and cycle life of lithium batteries used for energy storage are much higher than those of ordinary lithium batteries. It is also widely used in energy storage products such as electric vehicle batteries and wind power generation batteries. Now it is also widely used in household energy storage systems and so on.

4. Lithium batteries for energy storage can be used to provide DC power supply and backup power for large-capacity batteries such as automobiles, ships, aircraft, and unmanned vehicles.

Lithium-ion batteries have the characteristics of small size, high energy density and long cycle life. In the power system, it can provide power for the power grid, and is used to adjust or control characteristic parameters such as voltage and frequency to realize the scheduling of power, and can also be used to automatically adjust the voltage or power of the grid. Lithium batteries can not only provide DC power supply and backup power for large-capacity batteries, but also be used in conjunction with energy storage devices, and can be used as auxiliary power supplies for energy storage systems. For example, in the mobile energy storage system (mobile charging pile) that is being vigorously promoted in some areas of our country, lithium batteries are also used as auxiliary power sources. In addition, lithium batteries are widely used as power batteries in some new energy vehicles.

5. Other application areas, including batteries for home lighting (DFB, AC, DC).

As the requirements for energy saving and emission reduction become higher and higher, the scale of the home lighting market is gradually expanding, and the demand for batteries for home lighting will continue to grow. 21700 batteries can realize the highly integrated, modularized and integrated home lighting batteries. The 21700 battery has no pollution to the environment, no smell, no pollution, good product safety, and will not generate a lot of heat during use. long lasting.
