Monitoring results

In a UPS or in a Solar Energy System, normally, a certain number of batteries are connected in series to obtain a sufficiently high voltage to feed an inverter. A 'chain' of batteries connected in this way is usually called a string. A system may contain from 1 to N strings, according to the power requested. For the scope of checking on the system's state of health, the most important item to watch is the string, rather than the single battery.

As mentioned before, the Boris BMS is especially adapted to the surveillance of battery strings. For this reason, the results obtained form the monitoring activities are aggregated by string. Boris BMS has implemented three different views to present the data:

String: summary

This graph contains six indicators to present the state of health of a monitored string. The first row shows three gauges indicating the Voltage state of the string:

  1. Green: the number of batteries with a correct Voltage
  2. Yellow: the number of batteries with a critical Voltage
  3. Red: the number of batteries with an insufficient Voltage

The second row shows three counters indicating the Temperature state of the batteries:

  1. Light blue: the number of batteries with a correct Temperatura
  2. Lilac: the number of batteries with a raised Temperature
  3. Red: the number of batteries with an excessive Temperature

String: detail

This graph shows in a single view the state of a string in detail: the upper histogram shows the Voltage of each battery, in height as well as in number. The lower histogram depicts the same information regarding the Temperature. Naturally, the order in which the data is presented is exactly the same order in which the batteries are placed within the string, with the Voltage increasing from left to right.

String: single board details

In case of long strings which comprise many batteries, it may be useful to view the state of just the twelve batteries attached to one single Boris board. The way in which the data is shown is of cause the same as in the view of the string as a whole.

How to access these results?

The Master Control Unit has built-in a DB-server, a web-server and a Graphics-server.
The application program, also installed on the Master Station, stores the results of the measurements made by the Monitoring Devices into a DataBase. The Graphics-server periodically executes queries against the DataBase to obtain the latest results and presents them graphically on a web-page, like shown above.
There are several ways to access and visualize the data on screen:
- directly on the screen of the Master Control Unit
- by installing the Master Control Unit as a host on a LAN and accessing the MCU graphics pages from any host  on the network using a web-browser
