Battery Pack Wiring Harness

What is a new energy BMS? The Chinese name of BMS is power battery management system, which mainly monitors and manages the battery.

 

New energy vehicles are also equipped with BMS battery management systems, which monitor the battery cells, voltage and vehicle voltage.

 

The BMS Battery Harness is an important part of the new energy battery pack BMS system. It is the carrier for signal transmission between the various components of the system, and is responsible for transmitting the voltage and temperature signals of the battery components to the BMS system in real time.

 

The electromagnetic environment of the whole vehicle where the BMS is located is complex, especially when the high-power equipment of the car is working, it will generate a lot of electromagnetic interference, which will affect the normal operation of the BMS. In order to facilitate the accurate collection of battery voltage, current and other data. This requires high temperature resistance, high voltage resistance, tortuosity and flexibility of the battery pack harness.

 

The battery pack harness plays a vital role in the BMS (battery management system) to ensure stable and reliable signal transmission. The following are the main functions of the battery pack harness:

 

1. Protect the battery cell connection wires and battery packs from damage to ensure their safe operation.

 

2. Maintain the battery in an appropriate voltage and temperature range to meet the needs of the whole vehicle.

 

3. Perform battery parameter detection, including monitoring of total voltage, total current, single cell voltage, temperature, insulation, collision and impedance.

 

4. Monitor the status of the battery, such as SOC (state of charge), SOH (health state) and SOF (functional state) of the connecting wire.

 

5. Implement online diagnosis, including sensor failure, network failure, battery failure, overcharge, over discharge, overcurrent and insulation failure.

 

6. Ensure the safety of the battery and issue warnings when necessary, including temperature control system and high voltage control. Once a fault is detected, the BMS battery harness will pass the information to the vehicle controller and charger to ensure the safety of the battery, including leakage protection.

 

7. Control the charging process, including slow charging and fast charging control of BMS.
