Overview
The ABAT100-HS is the central management unit of the battery monitoring system, responsible for collecting and processing data from up to 120 individual battery modules. It communicates via UART bus with ABAT100-S single battery modules and ABAT100-C string modules, analyzing voltage, internal resistance, temperature, and charge/discharge current in real time, while estimating SOC (State of Charge) and SOH (State of Health) for both the string and individual cells. With an RS485 interface and MODBUS-RTU protocol, it seamlessly integrates with third-party monitoring systems or touchscreens. Powered by DC24V and easy to install, it is ideal for centralized battery management in data centers, substations, communication base stations, and industrial UPS applications.

FAQ
ABAT100-HS is powered by an external DC24V supply, typically from a switching power supply like KDYA-DG1502-12K. It features overvoltage and short-circuit protection. Power consumption is low (estimated <2W, though not specified).
One collector can manage up to 120 ABAT100-S single battery modules, plus ABAT100-C string modules and optional others.
Two methods: 1) Connect a touchscreen for graphical configuration; 2) Use MODBUS commands via RS485 from host software.
The module provides LED indication. When integrated with a touchscreen or monitoring platform, it supports local sound/light alarms, SMS alerts (with additional equipment), etc.
Mount with tie-downs or adhesive, avoiding high temperature, humidity, and strong electromagnetic interference. Ensure stable DC24V power, use shielded twisted-pair for communication, and ground properly.
Via UART bus using MODBUS-RTU protocol. The collector acts as master polling each slave module. Communication parameters (baud rate, etc.) are configurable; default 9600, 8, N, 1.
Summary
The ABAT100-HS collector is the core of the ABAT100 series battery monitoring system, integrating data acquisition, processing, alarming, and communication. It manages up to 120 individual batteries, monitoring voltage, internal resistance, temperature, and charge/discharge current in real time while estimating SOC/SOH to provide accurate battery health assessment. With RS485 MODBUS-RTU protocol, it seamlessly connects to touchscreens or third-party monitoring platforms for local or remote management. Powered by DC24V and flexibly installed, it features overvoltage and short-circuit protection, making it ideal for data centers, substations, and communication base stations. With ABAT100-HS, maintenance teams can centrally monitor battery string status, detect potential failures early, and ensure backup power reliability and extended battery life.
