The BMS system is a core component of electric vehicles and hybrid electric vehicles, serving as the heart of the power system. It is mainly used for online detection and real-time monitoring of automotive batteries, providing information such as battery voltage, current, temperature, SOC (State of Charge), and insulation status to the entire vehicle. Additionally, it continuously assesses the battery's operational status and the consistency of the battery pack. In the event of a fault, the system promptly sends fault signals and alerts to the vehicle. Its detailed functions are as follows:

1. Fault Prediction and Alarm

During the operation of the battery pack, individual batteries may frequently become damaged. If such issues are not detected in time, they can affect the performance of other batteries, ultimately leading to damage to the entire battery pack. The battery management system can promptly identify faults and notify maintenance personnel for repair or replacement, thereby extending the lifespan of the battery pack.

2. Active Balancing Function

Due to unavoidable inconsistencies during battery manufacturing, voltage discrepancies occur during operation. This results in batteries with smaller capacities frequently experiencing overcharging, leading to shortened lifespan. The intelligent battery management system can balance these inconsistencies, reducing damage caused by overcharging.

3. SOC (State of Charge) Estimation

In applications where strict monitoring of remaining battery capacity is required, the intelligent management system utilizes a high-precision, high-sampling frequency measurement system to estimate the battery's SOC.

4. Remote Monitoring Interface

The system is equipped with RS-485, CAN, and other communication interfaces, enabling remote real-time monitoring through specialized software. The software is user-friendly, with a clear and intuitive display.
