20S 72V 40A Li-ion Battery BMS Module Battery Charger Protection Board for EV Industrial Equipment

20S 72V 40A Li-ion Battery BMS Module Battery Charger Protection Board for EV Industrial Equipment 0

The BAKTH-021S100A-0019-01 is a high-voltage, industrial-grade protection board exclusively optimized for 20-cell series (20S) lithium battery packs—supporting Li-ion chemistries—with a maximum discharge current of 40A. While its model code includes “021S” (indicating broad design compatibility) and “100A” (denoting extended current handling potential), it is fine-tuned for 20S configurations (nominal voltage: 74V for Li-ion) and calibrated to deliver stable protection for 40A medium-to-high power applications. This makes it an ideal choice for high-voltage devices like electric mobility gear, industrial tools, and mid-scale energy storage systems.

20S-Specific Protection & 40A High-Current Safeguards

Tailored to address the unique risks of 20-cell high-voltage packs, the board delivers multi-layered protection aligned with 20S dynamics and 40A discharge demands:

  • Overcharge Protection: Triggers at 4.25V (Li-ion) per cell, instantly cutting charging current to prevent thermal runaway—critical for 20S packs where cumulative voltage (up to 85V fully charged for Li-ion) amplifies overcharge hazards.
  • Undervoltage Protection: Shuts down discharge at 2.5V (Li-ion) per cell, avoiding irreversible capacity loss from “weak cells” that can disable the entire 20S system, especially during 40A high-load operation (e.g., electric motor startup).
  • 40A Overcurrent & Short-Circuit Protection: Blocks currents exceeding 40A (max discharge) or 120A (peak surge), shielding the 20S pack and connected devices (e.g., heavy-duty e-scooters, industrial grinders) from burnout during sustained high-power use.
  • 20-Cell Active Balancing: Automatically equalizes voltage across all 20 cells during charging, eliminating uneven charge distribution—a persistent challenge in high-cell-count packs. This extends the 20S pack’s lifespan by up to 40% compared to unbalanced systems and maintains consistent 40A discharge performance.
