What are the components of 502030 battery

 

Let's take a look at the composition of power lithium batteries and the uses of their components:

 

1. Battery cell: The smallest unit that constitutes a battery, generally composed of a positive electrode, a negative electrode, an electrolyte, etc., and its nominal voltage is the open circuit voltage.

 

2. Battery module: Several battery cells are welded together in parallel to form a battery pack. Several battery packs are connected in series to form a battery unit.

 

3. Battery unit: Dozens of battery cells or battery packs are connected in series to form a battery unit. Several battery cells are connected in series to form a power lithium battery assembly.

 

4. CSC acquisition system: Each battery cell has a CSC acquisition system to detect the voltage and temperature information of each battery cell or battery pack cell. The CSC acquisition system reports the relevant information to the battery control unit (BMU) and performs cell voltage balancing according to the instructions of the BMU.

 

5. Battery control unit: installed inside the power lithium battery assembly, it is the core component of the battery management system. The battery control unit (BMU) reports the single cell voltage, current, temperature and vehicle high-voltage insulation information to the vehicle control unit (VCU) and completes the control of the power lithium battery according to the instructions of the VCU.

 

6. Battery high-voltage distribution unit: installed at the positive and negative output ends of the power lithium battery assembly, it consists of a high-voltage positive relay, a high-voltage negative relay, a pre-charge relay, a current sensor, and a pre-charge resistor.
