2.5mm Automotive PCBA Assy Layout For ​​EV Battery Management BMS

​Professional Automotive PCBA Assembly for ​​EV Battery Management (BMS)​​

♦ What's ​​EV Battery Management (BMS)?

An ​​Electric Vehicle Battery Management System (BMS)​​ is a critical component that monitors, controls, and optimizes the performance, safety, and lifespan of the battery pack in electric vehicles (EVs) and hybrid electric vehicles (HEVs).

♦ Key Functions of a BMS:​

• • ​​Cell Monitoring & Voltage Balancing​​

    • Measures individual cell voltages to ensure uniformity.
    • Prevents overcharging or deep discharging by balancing cell voltages.

  • ​​State of Charge (SoC) Estimation​​

    • Tracks the remaining battery capacity (like a fuel gauge).
    • Uses algorithms (e.g., Coulomb counting, Kalman filters) for accuracy.

  • ​​State of Health (SoH) Monitoring​​

    • Assesses battery degradation over time.
    • Predicts remaining useful life based on usage patterns.

  • ​​Thermal Management​​

    • Monitors temperature to prevent overheating or extreme cold damage.
    • Activates cooling/heating systems to maintain optimal operating conditions.

  • ​​Overcurrent & Short-Circuit Protection​​

    • Detects excessive current draw and disconnects the battery if needed.

  • ​​Communication & Data Logging​​

    • Interfaces with the vehicle’s control system (via CAN bus).
    • Stores performance data for diagnostics and optimization.

  • ​​Charge/Discharge Control​​

    • Regulates power flow to maximize efficiency and safety.
