Predictive Insight for Your Battery Bank
At Chhabi Electricals, we understand that your battery bank is the last line of defense during a power outage. Our BHMS (Battery Health Monitoring System) converts it from a passive backup into a fully managed, predictable asset — extending its operational life, preventing costly failures, and ensuring your critical systems stay protected.
Track 1.2V, 2V, and 12V cells, string currents, and ambient conditions.
Internal resistance, cycle count, SOH & SOC analysis.
Modbus RTU/TCP integration with automated alarms (email/SMS).
Capture and analyze historical charge/discharge, voltage/temperature trends, and faults.
BATMOD, STRMOD, and CONMOD modules for flexible expansion.
Up to 2000 V via opto-isolation for high-voltage safety.
