Abstract

A method for grounding a hybrid or electric road vehicle which has been involved in an accident, includes making contact with a body of a road vehicle which has been involved in an accident using a first grounding tool, and subsequently grounding a second grounding tool which is connected to the first grounding tool via an electrical line and an apparatus for grounding a hybrid or electric road vehicle which has been involved in an accident. The apparatus has a grounding line, a drive-in tool for being driven into a body of the road vehicle, and a grounding stake for being planted into the ground. The drive-in tool is connected to one end of the grounding line and the grounding stake is connected to the other end of the grounding line.

First claim

What is claimed is:

1. A method of using a portable grounding device involving a road vehicle that employs an electrical propulsion system comprising the steps of;
initially identify a hybrid or electrical vehicle which is potentially a source of errant or stray voltages due to an accident or other such compromise to the electrical propulsion system; and
establish secure contact between a conductive, readily accessible portion of the road vehicle using a first grounding tool and a second grounding tool located away from the source of errant or stray voltages; where
the first grounding tool is in the form of a lever, a breaking tool or a Halligan tool which is driven into the conductive, readily accessible portion of the road vehicle; and
the second grounding tool is connected to the first grounding tool by an electrical line; thus
establishing a conductive path to ground for any errant or stray voltages thereby containing potential hazards to human beings.

2. The method as claimed in claim 1 , wherein the second grounding tool is driven into the ground.

3. The method as claimed in claim 1 , wherein the second grounding tool is connected to a grounded object.
