BMS1102S

MONITOR UNIT
 


 
Summary & Features

Summary

The BMS1102S Battery Monitor is designed to be used within an array of other BMS1102S Monitors and a Master BMS Controller (e.g. BMS1000M) to form a high accuracy Battery Management System. Data and commands are transmitted and received via CAN 2.0B interface which connects these units.

The BMS1102S Battery Monitor measures the voltages of 6 – 12 series connected battery cells, and can apply a 22Ω shunt resistor across each battery cell to bleed off excess charge (passive balancing). The BMS1102S also measures the resistance of up to 12 thermistors to determine cell temperatures.
