Abstract

AIM: This work aimed to determine the required charging voltage of the battery using an on-board charging winding based on electromagnetic energy generated by the alternating current of the contact wire.

METHODS: A mathematical model was created in COMSOL Multiphysics® 6.0 using Maxwell’s equations and the finite element method to calculate the induced electromotive force in the on-board winding of an unmanned aerial vehicle.

RESULTS: The relationships between the electromotive force induced in the on-board charging winding and its parameters and the distance to the contact wire were determined. The study shows that for a 600 A current in the contact wire, the charging current can allow for battery recharging and the winding weight does not exceed the multicopter lifting capacity.

CONCLUSION: This method may only be recommended for battery recharging of an unmanned aerial vehicle.
