U-Charge® RT is a Lithium Iron Magnesium Phosphate ‘plug-and-play’ replacement module for applications typically requiring better run time, zero maintenance, reduced charge time and high frequency operation readiness.
The RT offers 40Ah with peak load capability of up to 80A incorporating built-in automatic protection. At half the weight of a comparatively sized lead-acid battery module U-Charge® RT is a increasingly being used for applications that are restricted by lead acid battery limitations and replacement down time.
Comparing U-Charge® LiFeMgPO4 to other chemistry
U-Charge® RT Lithium Iron Magnesium Phosphate (LiFeMgPO4) modules have considerably greater energy density making them particularly suitable for numerous applications. LiFeMgPO4 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
Compared to Nickel Cadmium (NiCd)
- High rate of self-discharge at high temperature.
- Cadmium is highly toxic
- Use in batteries is controlled
- Environmental recycling issues
- Memory effect is one of the biggest disadvantages to using NiCd.
Compare LiFeMgPO4 to Nickel Metal Hydride (NiMH) suffers from:
- Poor charge retention
- Memory effect
- Higher cost
When not in use Sodium (Na-NiCl2) batteries typically require to be left on charge, in order to be available for use when needed.
If shut down,the reheating process lasts 24 hours, and then a normal charge process of 6-8 hours is required for a full charge.
Inefficiency due to energy consumption when not in use.
Built-in automatic protection for over-charge, over-discharge and over-temperature conditions
No battery management system required
Series connection up to four (4) batteries (48 V)
LED battery status indicator
Flame retardant plastics
Thousands of cycles, under normal conditions
Can be charged using most standard lead-acid
Optional battery discharge indicator ( U-BDI ) for SOC display and fault indication
In terms of cycling performance U-Charge® RT displays excellent characteristics.
Current cycling demonstrates minimal linear fade reaching over two thousand eight hundred full one hundred percent charge and discharge cycles to eighty percent depth of discharge.
U-Charge RT® Peripherals ensure optimum performance, monitoring and control of battery modules.
Battery Discharge Indicator
The BDI can be used with up to 4 U-Charge® RT 12V battery modules connected in series or parallel for fault and SOC indication.
The module Diagnostics ToolKit enables a battery module
to communicate directly with a PC. It includes an RS485
to USB converter allowing data transfer
