1. A method of tracking an electric vehicle comprising:
- receiving an actuation signal; and
adjusting a switch mode power supply in response to the actuation signal such that the switch mode power supply generates a detectable electromagnetic signal,wherein the switch mode power supply is used to provide alternating-current (AC) power to an electric motor of an electric vehicle (EV) or is used to provide direct-current (DC) power to a battery of the EV.

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