Remote Battery Monitoring (RBM) Systems

The Remote Battery Monitoring Systems are BTM-Simple and BTM-Net.

BTM-Simple

The BTM-Simple is composed of the Remote Monitor Unit (RMU) with built-in fiber-optic transmitter/receiver pair, 2 to 260 BTM Picos, connected into a daisy chained fiber optical network and, optionally, a Factstar (float current monitoring device) for discharge, recharge, and float-current measurements.

Distance between BTM Pico devices and RMU can be up to 90 meters. Reliable communication link facilitates rapid data sampling and near real-time data display.



BTM-Net

The BTM-Net is composed of one RMU with built-in multi-directional IR transceivers, 2 to 120 Pico M's with an IR communication option.

All system components must reside in an area less than 20 meters and line of sight is a requirement. Data exchange speed is moderate. No connection between individual components. Redundant data records in every device.



RMU: Remote Monitor Unit

Powered by a Raspberry Pi, the RMU runs on Linux and acts as a node for reporting battery health data collected by the BTM Pico or Pico M devices.

The report pages can be accessed from any authorized node connected to the provided network.

The RMU has the same functionality as the BTM Global, except it is a smaller and lightweight system meant for smaller installations. The size of the system is limited to a maximum of 260 BTM Pico or 120 Pico M devices.

The RBM has by default 2x16 character display for local data readout, 4 button keypad for simple data access and configuration, option for video-camera module. The terminal unit has built-in Ethernet support, dynamic HTML based user interface and large non-volatile memory for data storage.



BTM Pico

The BTM Pico is an inexpensive battery monitoring device. The main design goal was to compose a monitoring system which is simple and modular, provides a noise immune means of communication and make the installation as quick as possible.

Each individual module is electrically isolated from one another, hence the system is well suited for batteries operating at very high potential. A fiber-optical communication network provides a noise immune means for data exchange.



Pico M

Pico M was designed in response to customer requests for economical battery data logging system which does not require wiring to the central console.

The Pico M weighs only 10g and 8mm in thickness. A single device is connected to a battery jar with two leads, measuring a jar's voltage, the post temperature and optionally an auxiliary input.

High brightness LEDs provide indication of device's operational status. Pico M devices are available in standard and extended memory capacity versions and with IR data network option. Pico M devices are capable of collecting measurement values, alarm conditions and calculated battery performance data.



Pico D

Pico D was designed in response to customer requests for economical battery data logging system which does not require wiring to the central console.

The Pico D weighs only 10g and measures 32mm x 38mm. A single device is connected to a battery jar with two leads, measuring a jar's voltage, the post temperature and optionally a second jar input.
