ET3KRS Lithium Battery UPS Application Case for Modified Special

I. Project Overview

This project cooperates with a Beijing-based special vehicle technology company, aiming to solve the stable power supply problem of on-board equipment of modified special vehicles. To meet the power demand of mobile vehicle-mounted modification systems, monitoring equipment and control terminals during driving and standby shutdown, the project adopts the E3KS-48 UPS host matched with a 48V 50AH lithium iron phosphate battery pack. Replacing the traditional vehicle power supply and lead-acid battery scheme, it effectively solves the problems of insufficient standby battery life, large equipment volume, poor shock resistance and short service life of traditional power supply equipment for modified vehicles. The system provides continuous, stable and safe uninterruptible power support for various modified special vehicle equipment, ensuring the normal and stable operation of vehicle-mounted professional equipment in full working conditions.

II. Core Equipment Configuration

According to the installation space, vibration environment and power load characteristics of modified special vehicles, the project is equipped with a customized lithium battery UPS power supply system with compact structure and strong environmental adaptability:

Power Supply Host: The E3KS-48 special UPS host adopts high-frequency online conversion technology, outputs standard pure sine wave power, and has ultra-fast switching response. It can adapt to the unstable voltage and instantaneous power fluctuation of vehicle power supply during vehicle start, stop and driving. With perfect voltage stabilization and anti-interference performance, it can effectively protect precision vehicle-mounted modified equipment from power damage.
Energy Storage Battery: Equipped with a dedicated 50AH lithium iron phosphate battery pack for vehicles, it features high safety, strong shock and vibration resistance, small size and light weight, which is more suitable for limited vehicle installation space than traditional lead-acid batteries. Built-in intelligent BMS battery management system realizes full-range protection of overcharge, overdischarge, overcurrent, short circuit and high temperature, adapting to complex vehicle working conditions such as bumping and temperature change, and ensuring long-cycle stable power storage and power supply.

III. Application Advantages of the Solution

Professional Adaptation to Vehicle Modification Scenarios: The whole set of equipment is designed for vehicle-mounted modification working conditions, with compact and integrated structure, convenient for embedded installation and fixed wiring of modified vehicle cabins and equipment compartments. It perfectly matches the power supply needs of various special modified vehicles such as engineering operation vehicles, detection vehicles and command vehicles, with strong universality.
Strong Anti-interference and Stable Vehicle Power Supply: The E3KS-48 UPS host can effectively filter vehicle power supply ripple and voltage fluctuation, realize seamless switching between vehicle power supply and battery power supply, avoid equipment shutdown, data loss and program crash caused by flameout and power failure, and ensure the continuous operation of vehicle-mounted precision equipment.
Excellent Vehicle-grade Safety and Durability: Lithium iron phosphate battery has high thermal stability and will not burn or explode in extreme vehicle environments. It has excellent vibration and shock resistance, adapting to long-term road bumping during vehicle driving. The 50AH large capacity meets the long-time standby and offline power supply needs of vehicle-mounted equipment, and the long cycle life greatly reduces the frequency of equipment replacement and vehicle after-sales maintenance costs.
Lightweight and Space-saving: Compared with the traditional lead-acid battery power supply scheme of the same capacity, the lithium battery pack is smaller in size and lighter in weight, which does not occupy the limited installation space of modified vehicles, will not increase the overall load of the vehicle, and optimizes the overall modification layout and vehicle performance.
