Understand the Usage of 12V Lithium Ion Battery Pack

Ⅰ. The emergence of lithium batteries

In the battery market, lithium batteries have quickly occupied the market with the characteristics of energy saving, environmental protection, safety, low maintenance cost, long service life, value preservation, and large development space, and are gradually replacing traditional lead-acid batteries.

With the gradual maturity and update of lithium battery technology, energy storage lithium batteries are more and more widely used in many fields of life. The life of lithium battery solar street lights is a hot issue that many customers are concerned about. Let us briefly analyze the factors that affect the life of lithium battery solar street lights and the use of lithium battery life. There are many factors affecting the life of custom-made lithium-ion battery packs, such as ambient temperature, battery cycle times, charge and discharge status, etc. In addition, it is also closely related to lithium battery protection board, lithium battery controller, lithium battery production process and shell materials. The life of a lithium battery is generally 6 to 9 years, and there are many factors that affect the life of a lithium battery. Therefore, only a lithium battery with guaranteed quality can maximize its performance.

Ⅱ. Introduction to the use of 12v lithium-ion battery pack

12v lithium-ion battery pack protection board is a battery protection circuit board, generally used for large-capacity 12v lithium-ion battery packs, with overcharge, overdischarge, overcurrent, short circuit, battery balance function protection functions, some batteries may also require communication ports and data input and output options and other display functions to meet application requirements. 12v lithium-ion battery packs are used in electric vehicles, inverters, mobile DVDs, UPS, GPS, medical equipment, etc. The precautions for the use of 12v lithium-ion battery packs are:

1. Different brands of 12v lithium-ion battery packs, different cells, and different battery models are also different, and the chargers are naturally different and cannot be universal. If the chargers are often mixed and the charging voltage and current do not match, the battery will be charged.

2. Stop charging after the charger turns green in summer, and recharge for 1 to 2 hours after the charger turns green in winter. More than 12 hours, or even longer, it is easy to charge the battery.

3. When charging a 12v lithium-ion rechargeable battery pack at high temperature, the charging voltage is relatively high, and the battery is easily overcharged, which will cause the battery to lose water and dry up prematurely during charging, which seriously affects the service life of the battery. Research data shows that when the battery is in an environment of 45°C, the lifespan is shortened by 40%.

4. When the 12v lithium-ion battery pack is in use, the battery itself will heat up. If it is charged immediately after use, the battery will be in a high temperature environment for a long time, and it is easy to charge the drum.
