3.2.8 Intelligent Battery Monitoring System
The intelligent battery monitoring system consists of the CIM (CIM01C2) and BIM
(BIM01C3).
The communication interface module (CIM) is an intelligent battery management module that
collects wireless communication data from the downstream battery interface module (BIM)
groups, collects and analyzes the operating data of battery strings, calculates state of charge
(SOC) and state of health (SOH) of batteries and battery strings and estimates the battery
health status accordingly, supports battery tripping management, and uploads data to the
management unit through COM or PoE ports.
The BIM is a battery monitoring module that monitors the voltages, internal resistances, and
pole temperatures of batteries.
⚫
One CIM can support a maximum of 300 BIMs, and manage BIMs of a maximum of four battery
strings.
⚫
The BIM01C3 supports Shoto and Enersys batteries.
In the scenario with battery cabinets, the CIM is installed inside a smart module battery
cabinet and the CIM communications cable connects to a smart ETH gateway. Figure 3-29
shows the CIM and BIM networking in the scenario with battery cabinets.

If a battery system needs to be managed by multiple CIMs, CIMs can connect to northbound
devices over straight-through cables (the ECC supports four parallel CIMs) without being
cascaded, as shown in Figure 3-30.
