Modular Battery Monitoring System Architecture
The
Alpais Battery Monitoring System
uses a modular architecture consisting of three main hardware components:
Battery Module, String Module and Control Module. This structure supports
scalable cell-level and string-level monitoring for stationary battery systems.
The architecture can be adapted to different battery-bank sizes and project
configurations, from small UPS battery installations to larger industrial,
utility and critical-power applications.
The standard modular structure includes:
- One Battery Module for each individual battery or cell
- One String Module for each battery string
- One Control Module for up to 4 String Modules
- Each String Module can connect up to 120 Battery Modules
- Each Control Module can monitor up to 480 batteries across multiple strings
For battery strings containing more than 120 batteries or cells, additional
String Modules can be integrated within the same monitoring architecture.
See the
Industrial Battery Monitoring Solutions
page for related large-scale and industrial applications.

Battery Module (BATMOD)
Battery Modules are designed for lead-acid and Ni-Cd battery systems.
Available module versions support 6V, 12V and 1.2V/2V battery applications.
Each Battery Module measures individual battery voltage, internal resistance
and battery temperature, providing detailed visibility into battery condition
and long-term measurement trends.
The Battery Module includes a transparent cover and three status LEDs for
quick on-site indication.
Automatic addressing simplifies installation and helps reduce commissioning time.
String Module (STRMOD)
The String Module collects data from the connected Battery Modules and
transfers it to the Control Module.
It supports string-level monitoring including string voltage, string current
and charge and discharge behavior. Ambient temperature and humidity can also
be monitored according to the configured project architecture and sensors.
One String Module supports communication with up to 120 Battery Modules.
Application-specific examples are available on the
Battery Monitoring Applications
page.
Control Module (CONMOD)
The Control Module is the central unit of the architecture and is responsible
for collecting, processing and managing measurement data received from the
String Modules.
It supports up to 4 String Module connections and enables communication with
external monitoring platforms through protocols such as SNMP, Modbus RTU and
Modbus TCP. This supports integration with SCADA, DCIM, facility-management
and other supervisory systems according to the project requirements.
The system can store up to 10 years of historical data and provides Ethernet
connectivity for local or remote access.
Alpais provides Control Module configurations with and without an embedded
server. In the embedded-server version, Alpais Software is installed directly
on the Control Module, reducing the need for a separate external server or PC.
Measurement records and the monitoring interface can be managed locally on
the embedded Control Module according to the selected system configuration.
