Description
Portable Emergency Power Supply
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
