U-CHARGE RT SERIES

U-CHARGE RT

U-Charge RT – ‘Plug ‘n’ Play’ Cobalt-Free Battery with Internal BMS

The U-Charge® RT module is a ‘plug-and-play’ replacement module for lead acid applications typically requiring longer run time, zero maintenance, reduced charge time and high frequency operation readiness.

The U-Charge® RT series offers built-in automatic protection and an optional State of Charge indicator (Battery Discharge Indicator) and can be put in systems up to 48V. At less than half the weight of a comparatively sized lead-acid battery module, the U-Charge RT offers 70% more runtime and is increasingly being used for applications that are restricted by lead acid battery limitations and replacement down time.

Applications

  • Medical Cart
  • Industrial Floor Cleaner
  • Automated Guided Vehicle
  • Small Personal Vehicles
  • Robot and Autonomous Vehicle

Features

  • Built-in automatic protection for over-charge, over-discharge and over-temperature conditions

  • Series connection up to two (2) batteries (48 V)
  • Intra-module balancing
  • LED battery status indicator
  • Maintenance-free
  • Flame retardant plastics
  • Thousands of cycles, under normal conditions
  • Can be charged using most standard lead-acid chargers
  • Optional battery discharge indicator (U-BDI) for SOC display and fault indication

Peripherals

U-Charge RT Peripherals ensure optimum performance, monitoring and control of battery modules.

RT Battery Discharge Indicator

The BDI can be used with the U-Charge RT battery modules to show State of Charge/”Fuel Gauge” and any fault conditions.

Diagnostics Toolkit

The Diagnostics ToolKit enables a user to view individual cell voltages and temperatures within each module, as well as the ability to put the module into sleep mode for storage situations.

Chemistry

Comparing U-Charge® LiFePO4 to lead-acid:

U-Charge RT Lithium Iron Phosphate (LiFePO4) modules have considerably greater energy density making them particularly suitable for numerous applications. LiFePO4 is considered safer, less toxic, and more energy efficient with significantly longer cycle life.

Compared to Lead Acid

Commonly used in starter batteries for internal combustion engine (ICE) vehicles Lead Acid is normally a low-cost secondary battery, composed of a lead-dioxide cathode, a sponge metallic lead anode and a sulphuric acid solution electrolyte. The heavy metal element makes lead acid batteries toxic and improper disposal can be hazardous to the environment.

Disadvantages of lead acid batteries include:

  • Failure between several hundred and 2,000 cycles
  • Comparatively low energy density,
  • Long charge time
  • Careful maintenance requirements
