Can lithium ion battery pack be used in high/low temperature environment.solar energy storage lifepo4 battery 48v 100ah

　　With the launch of energy conservation and environmental protection, in the current type of battery products, lithium -ion batteries quickly occupy the mall with many advantages and gradually replace traditional lead -acid batteries. The capacity is one of the important parameters of lithium ion battery, and its size changes with the temperature. In terms of the operation of the lithium -ion battery in high temperature and low temperature, does it have a great impact on lithium ion battery packs? Can lithium -ion battery packs be used in high temperature texts and low temperature environments? Lithium battery manufacturers come and talk to you, let's take a look together!

　　Some large devices and equipment need to resist high -temperature lithium -ion batteries. Because lead acid is not environmentally friendly, has low energy density, large volume, short life, and heavy weight, and other defects. The newly developed products developed by merchants or batteries that are upgraded through transformation are basically selected. Power supply system. In order to ensure the life and safety and reliability of lithium ion batteries, the advanced protection system will be selected in the high -temperature lithium -ion battery pack, which is alert to overcharge, overload, high temperature operation, low temperature charging, or short circuit, or even safety. Sexual issues.

　　Through expert decomposition, the temperature constraints set by mobile phone lithium-ion batteries are generally 40-60 degrees, and the explosion-proof valve is marked on the battery, while high temperature-resistant lithium-ion batteries can accept 800 degrees of high temperature. In the high -temperature exploration of general lithium ion batteries, there are 200 degrees, 500 degrees and 800 degrees, etc., but in general, the foundation will not be exposed to such high temperature in daily life, but we can see charging from time to time. Or excessively use the battery to damage the battery. In particular, more and more intelligent devices are configured with twists and turns. The safety test alone has up to 50 safety monitoring processes. Among them, high -temperature projects exceed 50 degrees when the twists and turns are turned into. , Such temperature, twists and turns batteries are unlikely to be exposed.

　　Low-temperature lithium-ion battery Low-temperature lithium ion battery refers to the operating temperature below -20 ℃, and at the same time, it can satisfy the lithium battery national standard GB31241-2014 "Lithium Battery and Battery Pack Safety Requirements for Portable Electronic Products" Perhaps National Military Specifications GJB4477-2002 "Lithium ion" "Lithium ion Lithium batteries required by battery packs "required. For the operation of the lithium -ion battery at low temperature, the impact is still not small. Because the capacity of the lithium -ion battery will decrease at the extremely low temperature, the use time will become shorter. Feel the phenomenon of clear power. However, low -temperature lithium -ion batteries also have limited specifications, and generally there is no problem at minus 20 degrees.

　　Lithium battery manufacturers tell you the method of conditioning the temperature conditioning of lithium -ion battery packs

　　◆ Internal conditioning

　　The temperature sensor is placed in representativeness, the temperature changes with large temperature changes, especially the high temperature and low temperature places, and the calories accumulation of the center of the center of the lithium -ion battery set.

　　◆ External conditioning

　　During the cooling condition: At present, considering the complexity of the thermal processing structure of the battery pack, most of them use the simple and cold -cold method. And considering that the uniformity of heat dissipation is mostly used in parallel ventilation methods.

　　Heating and conditioning: The simple heating method is to add heating plates to the lithium -ion battery pack to implement heating, and the front and rear heating lines around each lithium -ion battery group may use the heating film to be covered around the lithium -ion battery pack. heating.
