A new approach to large scale battery status monitoring. A non-invasive, easy to install, inexpensive monitoring system that can be attached to virtually every type of existing battery array like UPS or Solar Energy system.

Boris 1.42 Board
The BMS also has one Master Control Unit to supervise and coordinate the activities of the connected boards. This unit communicates with the Monitoring Devices through a RS-485 channel or by radio. At user defined intervals, this unit broadcasts a Measurement Request to all connected devices.
When the Boris PCB's receive this request, the on-board application engages in the following operations:
To monitor a system of this size, 108 batteries, only nine Monitoring Devices are needed. Please take note that you can attach to a specific Boris board only consecutive, in series connected batteries, belonging to the same string.
In one glance the state of health of an entire string: the number of batteries with the right Voltage, with a just sufficient Voltage and then the number of batteries below threshold Voltage. On the second line the number of batteries with a normal Temperature, with a slightly raised Temperature and last the number of batteries that are over-heated.
In a single graph are displayed Voltage and Temperature of all batteries belonging to the string. Malfunctioning batteries can be identified immediately, long before they collapse.
With this type of diagnostics, there's plenty of time to schedule corrective actions.
When the string contains many batteries, it's possible to zoom in and visualize only those cells that are controlled by a single Boris board.
