Description

[0001] WIRELESS CHARGING SYSTEM AND METHOD [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote wireless charging support system and method, and more particularly, to a remote wireless charging supporting system and method for supplying electric energy remotely to ensure continuous mission performance and improve the continuity and efficiency of mission performance .

Conventional tanks, combat vehicles, or tactical vehicles have driven their internal generators to supply power when they consume all the electric energy charged to the internal power supply battery when performing the mission from a remote location. However, if the energy to drive the internal generator is also exhausted, the battery must be replaced or returned to the base to re-supply the energy required for the generator and the engine.

Therefore, it is not possible to guarantee the continuity of the mission performance of the ground weapon system unless the external energy is supplied. In addition, it is cumbersome and time consuming to manually return energy to the base for energy supply when performing mission at a distance. It is also difficult to manually supply energy in automated and unmanned ground weapons systems.

Therefore, there is a need for a system to support electrical energy for continuous mission execution in an automated and unmanned ground weapon system.
