The power lithium battery is the power source of the power source of the tool, mostly refers to the battery that supply power for electric vehicles, electric trains, electric bicycles, and golf. Its important difference is the starting battery for the starting of a car engine. Mostly use valve port sealing lead -acid batteries, open tube lead -acid batteries, and lithium iron phosphate batteries.

Power battery component

Power battery manufacturers believe that the battery is important to composed of four parts: power lithium battery module, battery management system, power lithium battery box, and auxiliary components. The structure of the power lithium battery includes the following components:

1. Battery cover

2. Positive -active substance is cobalt oxide lithium

3. Dividation -a special composite film

4. Negative electrode -active substance is carbon

5. Organic electrolyte

6. Battery shell

The direct effect of power lithium batteries is to supply power sources for electric vehicles. Many electric lithium batteries of electric vehicles use ternary lithium ion batteries. This battery is based on lithium cobaltate lithium manganate or lithium nickel. The carbon material that can be embedded in the lithium ion is used as a negative electrode electrolyte.

The important difference between power lithium batteries is the starting battery used for starting of a car engine. Mostly use valve port sealing lead -acid batteries, open tube lead -acid batteries, and lithium iron phosphate batteries.

Features of power lithium batteries: high energy and high power; high energy density; recycling of high -power parts (HRPSOC) in a load (HRPSOC); wide range of working temperature (one 30 ~ 65 ° C); long service life, 5-10 years required 5-10 years ;Safe and reliable.

Power lithium battery installation location: Power lithium battery assembly is installed in the lower part of the car body. The components of the power lithium battery include each module assembly, CSC collection system, battery control unit (BMU), battery high -voltage distribution unit (Bbox), maintenance Switching and other components.
