Summary

The BMS1102S Battery Management System Monitor Unit 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 Management System Monitor Unit 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.
