ServersCheck Battery Monitoring System (BMS)
Industrial BMS system designed for monitoring lead acid, lithium-ion or nickel battery cells (PWR-BAT-CELL module image LEFT) and strings (PWR-BAT-STRING module image RIGHT).
Viking Part Numbers: PWR-BAT-STRING & PWR-BAT-CELL
Features
— for 2V, 6V or 12V batteries with M8 terminal connector.
— measures temperature, voltage & impedance of individual batteries
— measures battery string voltage and total impedance
— measures battery string charge and discharge current
— monitor for gas leaks from battery cells (HF, H₂, CO, CO₂) indicating possible thermal runaways
— plugs into the base unit
— powered by the base unit for up to 30 batteries. For more additional 12v PSU required
— alerts via SNMP Traps, email, SMS or voice calls
— wired or optionally wireless
— integrates via Modbus TCP, SNMP, JSON with other systems through the base unit
— optional MQTT version available to connect it to a cloud of your choice
— optional RS485-BAT-STRING module to directly connect the BMS to your Industrial Control Systems without needing the base unit
— CE and RoHs compliant
Module for Batteries — Monitoring Voltage, Temperature, and Impedance
This module (PWR-BAT-CELL) monitors the state and health of your individual batteries by monitoring their temperature, voltage and impedance. The modules are daisy chained to monitor multiple batteries. The module does not drain any power from your batteries as it is powered by the battery string module (PWR-BAT-STRING). Designed for 2V,6V or 12V lead acid, Li-ion or nickel batteries. Battery mountable, rack or DIN rail mount available.
Module for Battery String — Monitoring Impedance, Charge and Discharge Current
This module monitors your string of batteries. It connects to the different battery modules (PWR-BAT-CELL). It also includes a clamp based current transducer that is typically connected at the end of the string. At a string level it will provide you with the string's resistance, the charging or discharging current.
The module provides the power to all the PWR-BAT-CELL devices that are connected through daisy chain. Optional 12v power supply is available for larger strings (>30 batteries). RS485 output: optional version enabling you to integrate the BMS system with your own industrial control systems. Part number is PWR-BAT-STRING-485
Gas sensing: optional gas sensors available for detecting H₂, HF, CO and CO₂.
Battery Gas Leak Sensing
When batteries overheat they start leaking gasses which may or may not be ignited immediately. The optional gas sensing module detects for gasses for different battery types:
— for Li-Ion batteries monitor for following toxic gasses: Hydrogen Fluoride (HF), Carbon Monoxide (CO) or Carbon Dioxide (CO₂)
— for lead acid batteries the primary gas to monitor is the Hydrogen gas (H₂). Monitoring up to 100% Lower Explosive Limit (LEL).
The gas detectors can be optionally mounted onto the PWR-BAT-STRING module or can be purchased as separate gas sensors.
