LIMATECH TECHNOLOGIES

LITHIUM TECHNOLOGIES FOR AERONAUTICS

Lithium Iron Phosphate

Limatech chose the Nanophosphate® Lithium Iron Phosphate A123 System technology.
This technology has been selected as the most suitable in terms of power, safety and service life.

Avantage durée de vie Batterie Lithium Limatech face aux batteries du commerce Lithium est aux technologies plomb et Nickel-Cadmium

Mechatronics architecture

Limatech mechatronics architecture was designed to meet the DO160, DO311, DO254 aeronautical tests standards.

These aeronautical tests standards are intended for safety and dependability via :

  • Resistance to vibrations / shocks / flames...
  • Resistance to environmental constraints : pressure, humidity, oxidation et corrosion...
  • Resistance to mechanical stresses : torsion, flexion, traction, compression...
  • Electrical protections : courts circuit, sur-tension, sous-tension...
  • Prevention : alarm, electromagnetic field tests...

Balancing strategy

Lithium batteries age differently depending on their charges / discharges and temperature.

Without this technological brick essential to the good fucntionning of a Lithium batterie, accumulators can fall in deep discharge which causes a thermal runaway spreading to the other cells.

Limatech innovations on the Lithium battery balancing optimization strategy make it possible to use all the potential of accumulators, to increase the life expectancy and to increase the safety by preventing the domino effect of the thermal runaway of a defective accumulator.

Thermal strategy

The voltage of Lithium batteries decreases significantly in cold temeratures between -30° and +10° Celsius.

To guarantee the availability of your aircraft, in complete safety, even in extreme temperature conditions, the Limatech batteries integrate :

  • A Cockpit module for precise monitoring of voltage, load and temperature
  • A thermal heater that can be activated from the Cockpit module.
