Method and system for producing a detectable electromagnetic signal for tracking locations of an electric vehicle

Embodiments of the invention described herein use an electromagnetic signal produced by a switch mode power supply (SMPS) (202) to track locations of an electric vehicle (EV) (102). In one aspect, a method of tracking an EV (102) is described. This embodiment of a method comprises receiving an actuation signal (304); and adjusting a SMPS (202) in response to the actuation signal (304) such that the switch mode power supply (202) generates a detectable electromagnetic signal (208). The SMPS (202) is used to provide alternating-current (AC) power to an electric motor (106) of an electric vehicle (EV) (102) or is used to provide direct-current (DC) power to a battery (104) of the EV (102).
