# Boris Battery Monitoring System

<abstract>
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, what does it do?

The Boris BMS activity consists in measuring, at regular intervals, the Voltage and Temperature of each of the connected batteries. 
The measurement results are transmitted to the Master Control Unit that takes care of storing the data into a DataBase, displaying 
the results through a Graphics Web server and generating alarms according to client imposed criteria.

### Boris, how does it work?

The Boris BMS is based on the Boris 1.42 board, an intelligent device, developed by Seber IT specifically for this task. 
The board is equipped with Analog/Digital converters and is able to check on no less than twelve in-series connected batteries. 
An on-board micro-processor (made by using an [Acme Systems yarm board](/yarm)) with incorporated application program takes care of the necessary operations and activities in complete independence.

### TH02 temperature sensor

The activity of battery monitoring implies measuring the temperature of the battery body at regular intervals. Seber-IT has developed a thermo-sensor 
specifically for this purpose: Th-02, a small, flat, easy-to-apply mini-PCB to attach to the battery case. It suffices to apply a small piece of 
bi-adhesive tape or a droplet of glue, p.e. silicon glue, to affix it to the battery body.

The upper-side of the thermo-sensor is equipped with a special poke-in connector for two wires. By just inserting the stripped end of the wire into 
the connector, a stable connection will be guaranteed.
The underside of the Th-02 has two 'thermo-electrodes', in contact with the battery housing, that 'transmit' the battery body temperature to the sensor element.

### Boris Master Control Unit

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:

- Measurement of potential difference of the connected batteries - Voltage 
- Measurement of body temperature of the connected batteries - Temperature
- Data transmission to Master Control Unit - Transmission

The full measurement cycle, from preparation through measurements to data ready for transmission, takes less than one second! 
And what's more, the measurements are carried out simultaneously on all connected devices.
Data transmission is completed within the next few seconds and lasts less than half a second per board.

## Boris battery voltage cable

is a 13-conductor, 500 VDC cable to connect the batteries to be monitored to the Boris board. The connection table is:



Conductor #1: Minus-Pole Battery #1

Conductor #2: Plus-Pole Battery #1

Conductor #3: Plus-Pole Battery #2

Conductor #4: Plus-Pole Battery #3

....

Conductor #13: Plus-Pole Battery #12



## Boris Battery Temperature cable

is a 24 conductor, low voltage cable, to connect the Th-02 thermo-sensor, fixed on the body of the battery, to the Boris board.

The conductors are separated in 12 pairs, each pair must be connected to a thermo-sensor. The order in which the two conductors are inserted into the connector on the Th-02 sensor makes NO difference.



The connection table is:

Pair #1: thermo-sensor Battery #1

Pair #2: thermo-sensor Battery #2

...

Pair #12: thermo-sensor Battery #12



This cable is available in three different lengths: 1 mtr - 1,5 mtr - 2 mtr (Other lengths are available on request)
