3.5.4 iBAT 2.0
The intelligent battery monitoring system (iBAT 2.0) consists of the communication interface
module (CIM) and battery interface module (BIM). The CIM is an intelligent battery
management module which collects wireless communication data from the downstream BIM
groups, collects and analyzes the operating data of battery strings, calculates the state of
charge (SOC) and state of health (SOH) of batteries and battery strings, estimates the battery
health status, and uploads data to the SNMP card through the COM port. An external Hall
effect sensor is connected to the CIM to monitor the current of each battery string.
The BIM is a battery monitoring module that monitors the voltages, internal resistances, and
pole temperatures of batteries. It uploads battery data to the CIM through wireless
communication.
