Portable Emergency Power Supply with Lithium Iron Phosphate Cells, 3000 Charge-Discharge Cycles, and Wide Operating Temperature Range
Application Scenarios
The emergency DC power supply serves as a temporary backup power source during maintenance or when conducting full-capacity discharge tests using self-contained batteries, utilizing 110 kV or lower-voltage substation DC power sources.
Product Features
Energy Storage Component (Battery Pack)
Battery pack housing made of high-quality plastic with waterproof, shock-resistant, and pressure-resistant properties
Uses lithium iron phosphate cells with charge-discharge cycle life exceeding 3,000 cycles
Employs BMS (Battery Management System) that monitors voltage, current, and temperature of each cell with automatic balancing function and automatic power shutdown protection
Wide operating temperature range (-20°C to +55°C) with excellent cold resistance
Supports multiple parallel configurations to extend backup duration
Main Unit Composition and Technical Features
Provides stable output voltage of 171-249 V DC, suitable for any type of load with strong load-carrying capacity
Capable of handling instantaneous currents up to 20 times the rated load current
Equipped with LCD display module for visual interface displaying various parameters
Comprehensive protection against overcurrent, overvoltage, overload, and overheating with high reliability
Charge and Discharge Operation
Charging is prohibited when lithium battery pack state of charge (SOC) reaches ≥100% while maintaining normal electrical output
Charging initiates when lithium battery pack state of charge (SOC) is ≤85% while ensuring normal power output
Each time lithium battery pack is powered on and connected to AC power, it charges directly to 100% SOC
Maintains normal electrical power output when battery pack is not at low voltage
