G-TH Battery Monitoring System for Lead Acid
G-TH
G-TH Battery Monitoring System is equipped with battery thermal runaway early warning, high-accuracy SOC/SOH monitoring, and comprehensive intelligent analysis of the battery. With UL, CE and REACH certification, this BMS for lead acid batteries ensures safe operation of backup batteries in data centers, petroleum and petrochemical systems, and rail transit systems.
Key Features:
- Thermal Runaway AI Analysis & Early Warning: Predicts thermal runaway early via float current and temperature analysis
- Advanced Low Power Consumption: Reduces G-TH module standby current to 3 mA, far below industry average
- AI Data Analysis: Detects weak cells and exports clear, real-time intelligent analysis reports
- High-Accuracy SOC/SOH: Achieves ±5% SOC accuracy with Kalman filter and fuzzy neural algorithms
