ET3KRS Lithium Battery UPS Application Case for Modified Vehicles

I. Project Overview

This project cooperates with a Shanghai-based automotive technology company, focusing on the professional power supply demands of automotive modified equipment. In vehicle modification scenarios such as intelligent vehicle-mounted system upgrading, outdoor test vehicles, customized functional modified vehicles and supporting auxiliary equipment, traditional vehicle power supply and lead-acid batteries commonly suffer from insufficient standby life, poor vibration resistance, unstable voltage output and short service life. To solve the above pain points, the project adopts the ET3KRS UPS host matched with a 48V 50AH lithium iron phosphate battery pack. The solution provides stable, continuous and safe uninterruptible power support for vehicle-mounted intelligent equipment, detection terminals, control systems and customized modified devices, ensuring full-condition stable operation of modified vehicle equipment during driving, parking standby and outdoor testing.

II. Core Equipment Configuration

In view of the complex working conditions of vehicle modification including limited installation space, long-term road vibration and variable temperature environment, the project is equipped with a vehicle-grade compact lithium battery UPS power supply system with strong environmental adaptability:

Power Supply Host: The ET3KRS dedicated UPS host adopts high-frequency online power supply technology, delivering standard pure sine wave output with high voltage stabilization accuracy. It features zero-delay switching and excellent anti-interference performance, which can effectively resist vehicle power ripple, instantaneous voltage surge and drop caused by engine start-stop and driving vibration. It perfectly protects precision vehicle-mounted modified equipment from power failure and signal abnormality.
Energy Storage Battery: Equipped with a 48V 50AH vehicle-grade lithium iron phosphate battery pack, it adopts high-safety lithium iron phosphate cells, featuring shock resistance, low attenuation, long cycle life and wide temperature adaptability. Compared with traditional lead-acid batteries, it is smaller, lighter and more suitable for vehicle embedded installation. The built-in intelligent BMS battery management system realizes full protection against overcharge, overdischarge, overcurrent, short circuit and overheating, adapting to long-term bumpy driving and frequent charge-discharge working conditions of modified vehicles.

III. Application Advantages of the Solution

Professional Adaptation to Vehicle Modification Scenarios: The modular and compact design of the E3KS-48 UPS system fully fits the limited installation space of modified vehicles, requiring no complicated body transformation and supporting quick embedded installation and wiring. It is widely applicable to various modified scenarios such as intelligent vehicle modification, test vehicle equipment, customized functional vehicles and outdoor operation vehicles.
Strong Anti-Vibration and Stable Vehicle Power Supply: The whole system is optimized for vehicle working conditions, with excellent vibration and shock resistance. It can maintain stable power output during long-term vehicle driving and bumping, avoid equipment shutdown, data loss and system restart caused by power fluctuation, and ensure the continuous and reliable operation of vehicle-mounted modified equipment.
Lightweight and High-Efficiency with Long Service Life: The 50AH large-capacity lithium iron phosphate battery pack provides lasting standby power supply, meeting the power demand of long-time parking standby and offline operation of vehicle-mounted equipment. It features ultra-long cycle life and low attenuation, effectively reducing battery replacement frequency and later maintenance costs for vehicle modification. Meanwhile, its lightweight feature avoids increasing vehicle load and affects driving performance.
High Safety and Strong Environmental Adaptability: Lithium iron phosphate materials have high thermal stability with no combustion or explosion risk, meeting vehicle-grade safety standards. The system adapts to complex temperature changes in vehicle scenarios, ensuring stable operation in high-temperature and low-temperature environments, and fully meets the stringent safety and reliability requirements of automotive modification industry.
