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.
