1. A prerequisite for special low -temperature batteries is that the larger it, the larger the size, the better;

There are many types of low -temperature batteries, but there are also disadvantages. Only polymer lithium -ion batteries, lithium iron phosphate ion batteries, and ternary cobaltate ion batteries. Among the three types of lithium ion batteries, the energy density and quality of the lithium ion battery are the lithium, followed by lithium cobaltate, and finally the lithium iron phosphate.

The weight is a special special equipment. Its weight determines the work efficiency and safety of the soldiers, and the appropriate discharge power will affect their durability and the limit they can bear in the task.

2. The lithium ion battery used by the military must meet specific test requirements.

Regardless of the mechanical installations of civilian, special or special industries, safety performance is an important factor, but only different uses or occasions, and the requirements for their safety performance are different. Special low -temperature lithium -ion batteries, the safety factor is very high. First of all, the shooting test must be passed to ensure that the battery will not explode, followed by high -intensity impact, which cannot cause casualties.

3. When the specifications of special low -temperature lithium -ion batteries meet a certain temperature, the following points of charging requirements meet:

Because the low -temperature environment has a great impact on the performance of the battery, it is a very difficult thing to charge the battery in the low temperature environment. Special low -temperature lithium batteries need to be charged indoors in the outdoor. , So special low -temperature batteries must meet this requirement. Especially when charging outdoors, it is recommended to charge a battery at about -40 ° C.
