BATTMON Battery Monitoring Sensor – Professional Battery Monitoring System for Critical Applications

Introduction to Modern Battery Monitoring

The BATTMON Battery Monitoring System from AKCP provides an advanced solution for the continuous monitoring of various battery types. In a time where uninterruptible power supply is essential for businesses, data centers, and critical infrastructure, this DC voltage monitoring system offers the necessary security and control.

Technical Foundations and Functionality

The Battery Monitor Sensor combines three essential measurement technologies in a compact device: DC voltage measurement, current monitoring via Current Transformer (CT), and temperature sensing at the battery terminal. This triple monitoring capability enables comprehensive battery health analysis and delivers precise data on the condition of different battery systems.

The system operates with an impressive accuracy of ±0.05% full-scale in voltage and current measurements. The solar battery monitoring function supports voltage ranges of 0–15V, 0–30V, and up to 0–60V DC, and can monitor currents from 50A up to 2000A using appropriately sized current transformers.

Versatile Application Areas

Generator and Motor Monitoring

For generator applications, the BATTMON system offers crucial advantages in monitoring starter motors and alternators. Measuring starting current allows technicians to detect early signs of declining battery performance. A drop in current during startup often signals a weakening battery or issues with the starter motor, potentially leading to critical startup failures.

Monitoring the alternator’s charging current enables early detection of electrical system issues. This proactive UPS battery monitoring strategy prevents costly failures and unplanned downtime.

Solar Systems and Battery Storage

Solar system monitoring with BATTMON revolutionizes the management of photovoltaic battery systems. The system can monitor individual cell voltages, temperatures, and current flows in complex battery banks. Installing a current transformer on the battery stack allows for load monitoring, while an additional CT at the solar module output enables end-to-end monitoring.

This configuration allows plant operators to evaluate the efficiency of their solar panels, analyze voltage and current output, and compare both charging and discharging currents. The lead-acid battery monitor function is particularly valuable for traditional solar battery systems.

Uninterruptible Power Supply (UPS)

For UPS battery monitoring applications, the BATTMON system provides critical insights into the health of emergency power system batteries. Data centers, hospitals, and other essential facilities depend on reliable UPS systems that require regular battery supervision.

Technical Specifications and Performance Features

The battery monitoring system features robust technical specifications. With dimensions of just 56 x 55 x 33.3 mm, the device is compact enough for installation in tight electrical cabinets. DIN rail or screw mounting allows flexible installation options.

With an operating temperature range of -35°C to +80°C, the system is suitable for extreme environments. The temperature sensor with a 1-meter cable covers a range of -40°C to +75°C and enables current monitoring even under challenging installation conditions.

LED indicators for operating voltage and input signals provide instant visual status feedback. The system is powered via the sensorProbe+ family and requires no additional power source.

Installation and Safety Considerations

When installing the battery management system, key safety considerations must be observed. The BATTMON system is not galvanically isolated, so potential differences must be accounted for during installation. For batteries connected in series, individual cell monitoring is not recommended for safety reasons.

A maximum cable length of 10 meters using shielded low-capacitance cable or UTP allows flexible installation. The Phoenix connector for voltage, temperature, and external current transformer ensures secure and reliable connections.

Maintenance and Long-Term Reliability

The battery health monitoring functionality of the BATTMON system significantly contributes to extending battery life. Through continuous monitoring, operators can implement optimal charge/discharge cycles and avoid premature battery failures.

The system’s mean time between failures (MTBF) of 1,400,000 hours is based on field experience with sensorProbe units and highlights its long-term reliability. Surface-mount technology with highly integrated, energy-efficient components ensures lasting performance.

Compatibility and System Integration

The BATTMON system is exclusively compatible with the sensorProbe+ platform. During initial setup or after firmware updates, the sensor may undergo an automatic firmware update, temporarily rendering it unavailable. Smart sensor updates can only occur at the main sensor ports of SP+ units.

Selecting the correctly rated current transformer is critical to system performance. The CT value is factory-set and cannot be changed afterward, so specifying the correct rating prior to ordering is essential.

The Future of Battery Monitoring

As renewable energy and electrification across industries grow in importance, professional battery monitoring is becoming increasingly vital. The BATTMON system positions itself as a future-ready solution for demanding monitoring tasks in critical applications.

Its integration into existing monitoring infrastructures and compatibility with modern communication protocols make it the ideal choice for organizations seeking professional battery infrastructure oversight.
