ET3RKS Lithium Battery UPS Mobile Cabinet Power Supply Applicatio

I. Project Overview

This project serves a Shanghai-based environmental protection technology company, focusing on the uninterruptible power supply demands of the enterprise’s mobile cabinet equipment. It is equipped with the ET3KRS UPS host and 50AH lithium iron phosphate battery pack power supply system to replace the traditional lead-acid power supply solution. The system solves key pain points in the outdoor operation, temporary maintenance and scenario switching of mobile cabinets, including unstable power supply, insufficient battery life, heavy equipment and cumbersome maintenance. It provides a safe, stable and long-lasting emergency power supply guarantee for mobile cabinet equipment used in environmental monitoring, mobile operation and maintenance, and outdoor data collection scenarios.

II. Core Equipment Configuration

The project adopts an integrated lithium battery UPS power supply combination, which is suitable for embedded and rack-mounted installation of various standard mobile cabinets. The core configurations are as follows:

Power Supply Host: The ET3RKS dedicated UPS host adopts a high-frequency online power supply architecture and outputs pure sine wave current. It features voltage and frequency stabilization as well as seamless power switching, conforming to the power supply standards for monitoring equipment, transmission equipment and control modules inside mobile cabinets. It adapts to the working conditions of mobile equipment with frequent start-stop and frequent movement.
Energy Storage Battery: Equipped with a48V 50AH lithium iron phosphate battery pack, it has the core advantages of high energy density, compact size, light weight and long cycle life compared with traditional lead-acid batteries, perfectly meeting the portability and integration requirements of mobile cabinets. The battery is equipped with an intelligent BMS battery management system, which provides comprehensive protection against overcharging, overdischarging, over-temperature, short circuit and overload, and supports battery balance management, greatly improving power supply safety and battery service life.

III. Application Advantages of the Solution

Adaptable to Mobile Scenarios with Flexible Deployment: The entire equipment adopts a modular and compact design, which can be directly embedded into various standard mobile cabinets without complex modification. It is easy to disassemble, transport and relocate, fully adapting to the flexible deployment needs of the environmental protection industry in outdoor inspection, temporary monitoring and mobile operations, breaking the scenario limitations of traditional fixed power supply equipment.
Stable and Reliable Power Supply for Complex Working Conditions: The E3KS-48 host features fast response and zero switching delay during power failure, effectively avoiding equipment shutdown, data loss and monitoring interruption caused by mains power fluctuation and temporary power outage. Lithium iron phosphate batteries have excellent high and low temperature resistance, adapting to complex outdoor temperature and humidity environments to ensure all-weather stable equipment operation, which fits the harsh working conditions of outdoor environmental protection operations.
Cost Reduction and Efficiency Improvement with Convenient Operation and Maintenance: The 50AH large-capacity lithium battery pack provides sufficient battery life to support long-term offline operation of mobile cabinet equipment. Its longer cycle life than traditional lead-acid batteries greatly reduces battery replacement frequency and subsequent operation and maintenance costs. Meanwhile, the intelligent BMS system can monitor battery status in real time, facilitating equipment operation and maintenance management and reducing manual inspection costs.
Safe and Energy-Saving in Line with Industry Concepts: Lithium iron phosphate materials are safe, stable and heavy-metal-free with green and environmentally friendly properties, consistent with the development philosophy of environmental protection technology enterprises. The entire UPS system features low energy consumption and high conversion efficiency with remarkable energy-saving effects, balancing stable equipment operation and green and low-carbon development requirements.
