Components of the power battery_What is the use of the power battery

The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. It differs mainly from starter batteries used for car engine starting. Valve-sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used.

Components of the power battery

The power battery is mainly composed of four parts: power battery module, battery management system, power battery box and auxiliary components. The structure of the power battery includes the following components:

1. Battery cover

2. The positive electrode—the active material is lithium cobalt oxide

3. Diaphragm---a special composite membrane

4. Negative electrode ---- the active material is carbon

5. Organic electrolyte

6. Battery case

What is the use of power battery

The direct function of the power battery is to provide the power source for electric vehicles. The power batteries of many electric vehicles use ternary lithium batteries, which use compounds such as lithium cobaltate, lithium manganate or lithium nickelate as the positive electrode, so that lithium can be embedded. The ionic carbon material uses an organic electrolyte for the negative electrode.

The power battery is mainly different from the starting battery used for starting the car engine. Valve-sealed lead-acid batteries, open tubular lead-acid batteries and lithium iron phosphate batteries are mostly used.

Features of power battery: high energy and high power; high energy density; cyclic use under high-rate partial state of charge (HRPSOC); wide operating temperature range (-30~65℃); long service life, requiring 5-10 years; Safe and reliable.

Power battery installation position: The power battery assembly is installed at the lower part of the vehicle body. The components of the power battery include various module assemblies, CSC acquisition system, battery control unit (BMU), battery high voltage distribution unit (BBOX), maintenance switch and other components .
