Small Systems Battery Monitoring

Combining the power of ARM-9 and Linux

The SCMini-XC is based on a powerful ARM-9 microcomputer with an embedded Linux operating system. The architecture and capabilities are based on the SC4 system controller, which is field proven in thousands of monitored sites. This platform provides a wide range of functionality along with a full suite of secure networking protocols and utilities, including:

• IP V4 & V6
• SNMP V1, V2, V3
• FTP, SMTP, SSH, HTTP (webserver)

Scalable Monitoring Solution

The unit is equipped with two battery sensor interfaces for a total monitoring capacity of up to 48 batteries (24 per input). It also has a PBUS interface to allow use with other sensors, including float current measurement and general-purpose RIM and ROM I/O modules for facilities monitoring. More information on battery sensors and expansion modules can be found in the associated data sheets. The unit can be powered from a wide range of DC voltages from 9-60 VDC.

Monitored parameters include:

• Local line voltage
• Controller internal temperature (tracks ambient temperature)
• Battery voltage, temperature, impedance
• Battery electrolyte level (optional sensor)
• String float charging current (optional sensor)
• String discharge current (optional sensor)
• AC current (optional sensor)
• Moisture detection (optional sensor)
• Thermal runaway detection/control (optional sensor)
• Ground fault detection (optional sensor)
• Two built-in digital contact closure inputs
• Two built-in relay contact outputs
• USB-C programming connector
• Internal logging of all measurements and states

The built-in web server allows the status of the monitored batteries to be analyzed from anywhere in the network using a common web browser. The built-in SMTP mail client can be set up to send alarm messages to user-specified email addresses or text messages when an alarm occurs. A rules-based system allows combinations of states/conditions to set relay contact outputs.

The SCMini-XC, battery sensors, and all expansion modules are firmware downloadable over the network, facilitating firmware upgrades and feature enhancements as they become available.
