Energy Storage BMS Control Board PCBA

1. Project Overview
This OEM/ODM project demonstrates the hardware development and PCBA integration of a Battery Management System (BMS) control board for energy storage applications. The reference design uses a 4-layer, 120 × 80 mm PCB with an MCU + AFE architecture, active balancing, CAN/RS485 communication and conformal coating. Development covers schematic design, PCB layout, hardware calibration and circuit-system integration for customized energy storage battery management projects.

2. BMS Hardware Development
• Schematic Design: Develops the BMS hardware architecture and supporting circuits according to battery-pack configuration and system requirements.
• PCB Layout: Implements component placement, signal routing and power-circuit layout within the specified board structure.
• MCU + AFE Architecture: The reference design combines an MCU with an analog front end for battery monitoring, control and data processing.
• Hardware Calibration: Key hardware parameters are calibrated and verified according to the electrical requirements of the BMS project.
• Circuit-System Integration: Integrates monitoring, balancing, protection and communication circuits into the complete BMS control-board design.

3. Battery Monitoring & Management
• Active Cell Balancing: The reference design supports active balancing to manage voltage differences between cells within the battery pack.
• Overcharge & Over-Discharge Protection: BMS circuitry can support protection logic according to the battery-system design and defined operating thresholds.
• SOC/SOH Monitoring: Supports battery state-of-charge and state-of-health monitoring when implemented with the corresponding sensing, algorithms and system configuration.
• Battery Data Acquisition: The AFE-based architecture supports acquisition of key battery information required by the BMS control system.
• System-Level Management: The control board serves as a core hardware platform for monitoring and managing compatible energy storage battery packs.

4. Communication & Board Protection
• CAN Communication: Supports CAN-bus integration with compatible energy storage equipment and system controllers.
• RS485 Communication: Provides an additional communication interface for compatible external devices and energy management systems.
• Conformal Coating: The reference PCBA uses conformal coating to provide additional environmental protection for the assembled circuit board.
• 4-Layer PCB Design: The demonstrated project uses a four-layer board structure to accommodate the required power, signal and communication circuits.

5. OEM/ODM Development Capability
