As a core component of energy storage, batteries are widely used in data centers, communication base stations, rail transit, and other fields. However, swelling issues act like hidden bombs—mild cases shorten battery lifespan, while severe cases trigger fires or even explosions! How can 24/7 real-time monitoring and proactive protection be achieved? The DFUN Battery Monitoring System (BMS) offers an intelligent, full-scenario solution!
I. Deadly Causes of Battery Swelling & DFUN’s Solutions
1.Overcharge/Overdischarge – Precise Monitoring, Dynamic Adjustment
Cause: Excessive charging current or prolonged charging leads to internal gas buildup.
DFUN Solution:
Real-Time Monitoring: The PBMS 9000 series accurately monitors voltage, current, temperature, SOC/SOH of each cell, triggering instant alarms for anomalies.
Online Equalization: Automatically balances voltage differences between cells to prevent single-cell overcharging.
2.Plate Sulfation – Internal Resistance Analysis, Early Warning
Cause: Sulfation increases internal resistance, accelerating heat generation.
DFUN Solution:
Impedance Detection: PBAT 71/PBAT 81 sensors measure internal resistance in real time. Combined with the DFCS 4200 system, they analyze degradation trends and generate maintenance recommendations.
3.Thermal Runaway – Multi-Dimensional Temperature Control
Cause: Electrolyte drying or high ambient temperatures triggering thermal runaway.
DFUN Solution:
Dual-Temperature Monitoring: Internal battery temperature (negative pole) + ambient temperature/humidity (optional H-THD sensor), with a range of -20°C to 85°C (±0.5°C).
Thermal Runaway Monitoring: Dual monitoring of temperature + voltage, intercepting temperature rise and differentials—DFUN BMS blocks thermal runaway chain reactions with one click.
Thermal Spread Prevention: PBMS 9000 Pro supports optional hydrogen sensors (0-1000ppm) and insulation resistance monitoring (1kΩ~30MΩ), eliminating explosion risks.
4.Vent Blockage – Visualized Status, Remote Maintenance
Cause: Gas accumulation due to blocked vents.
DFUN Solution:
Breathing Light Design: PBAT 61 sensors display health status via LED colors (green/red). Multi-channel alerts (APP/SMS/email) are triggered for abnormalities.
II. DFUN BMS: From "Reactive Response" to "Proactive Protection"
Full-Scenario Coverage
Small Sites: PBMS 2000 (120 cells), an economical solution supporting Modbus/SNMP protocols.
Large Data Centers: PBMS 9000 (420 cells) supports IEC61850/MQTT and UPS high-frequency environments.
Harsh Industrial Scenarios: PBMS9000Pro (chemical plants/substations) UL/CE-certified, IP65-rated and anti-interference designed.
Smart Maintenance System
Cloud Management: DFCS 4200 platform supports centralized monitoring of 100,000+ batteries, 5-year data storage, and one-click CSV report exports.
Mobile Collaboration: Remote operation via HMI touchscreens or mobile apps, with real-time historical curves and fault diagnostics.
Predictive Maintenance
AI Prediction: Multi-parameter fusion algorithms (impedance, temperature, voltage) provide 30-day early warnings for battery failure risks.
Case Validation: Successfully deployed in high-pressure scenarios like Thailand’s True IDC and Saudi Aramco oil fields, reducing failure rates by 90%.
III. User Benefits: Safety + Cost Savings
✅ Safety: 24/7 monitoring + multi-level alerts, preventing swelling chain reactions.
✅ Cost Savings: Reduce manual inspections by 60%, extend battery lifespan by 2-3 years.
✅ Compliance: Meets global standards, including IEEE 1188 and ISO9001.
