G-TH WL

Battery Monitoring System

G-TH WL wireless battery monitoring system adopts a new generation of ZigBee wireless communication technology, which reduces on-site wiring by half and avoids hidden safety dangers of too many cables. It features convenient installation and shortens the on-site construction period. Certificated by CE standard, this BMS for lead acid battery is mainly applied in communication base stations, substations, enterprise data rooms, and other fields. Contact Gerchamp for reliable BMS for lead acid battery solutions. Reach out today to discover how we can enhance your battery performance.

Features:

ZigBee Wireless Communication

Real-time Data Monitoring and Alarming

Advanced Low Power Consumption Design

High-accuracy SOC/SOH (5) AI Data Analysis

Exclusive ZigBee wireless technology ensures reliable, low-loss communication for 600 cells.
Real-time monitoring of voltage, resistance and pole temperature with instant abnormality alarm.
Advanced low-power design keeps G-TH WL module current below 11 mA, far under industry average.
Online parameter identification + Kalman & fuzzy neural algorithm delivers ±5% SOC accuracy.
