Abstract

A location determination system for a material handling vehicle operating near a charging node. The system may include a power receptor configured to receive power from the charging node and provide current to the material handling vehicle. The system may include a sensor electrically coupled to the power receptor and configured to measure the current provided by the power receptor, and a controller configured to determine a current profile based on the measured current and determine a distance of the power receptor to the charging node based on the current profile. The system may determine the distance of the material handling vehicle from the charging node and may determine the location of the material handling vehicle based on a predetermined location of the charging node. The system may comprise multiple power receptors each with a current profile and may determine a speed and/or direction based on the multiple current profiles.
