Embodiment Construction

[0022] A vehicle's drive train is defined as the set of components in a vehicle that generate and transmit power through the vehicle's tires or wheels to the road surface to move the vehicle along the road. Hybrid electric vehicles and / or electric vehicles each use batteries to power their respective drive trains. Hybrid electric vehicles use a hydrocarbon fueled engine along with a battery provided on the vehicle to supply power to the hybrid vehicle's drive train. The electric vehicle's drive train uses only energy from the electric vehicle's battery for power. The battery of the hybrid electric vehicle and the battery of the electric vehicle, respectively, may include a plurality of batteries electrically connected in series or in parallel to form a single battery. When the operator of the vehicle drives or otherwise uses the vehicle (such as when powering the radio or windshield wipers in addition to powering the drive train), the charge on the battery may decrease so tha...

Abstract

A power safety system (PSS) includes a plurality of thermally-triggered electrical breaking arrangements (TTEBAs). The plurality of TTEBAs are associated with a plurality of electrical devices (EDs) disposed external to the PSS. The PSS further includes a plurality of electrical power connections (EPCs) associated with said plurality of TTEBAs that are configured to respectively electrically connect the PSS to the plurality of EDs. When at least one TTEBA in the plurality of TTEBAs is electrically operative and at least one thermal event occurs that is sufficient to thermally activate the at least one electrically operative TTEBA, at least the EPC associated with the at least one thermally activated TTEBA is electrically broken. A method to protect a human operator of the PSS from a thermal event is also presented. A PSS also extends to a primary and a secondary electrical charging system used to charge a battery of a vehicle.

Description

technical field [0001] The present invention relates to power safety systems, and more particularly to including a plurality of thermally triggered disconnect devices associated with a plurality of electrical devices disposed external to the power safety system, thereby associating the electrical connection PSS with the electrical connection PSS when the disconnect device is thermally interrupted A power safety system in which the electrical connections of electrical equipment are de-energized in relation to the de-energizing device. Background technique [0002] It is known to use battery chargers to charge batteries on vehicles. [0003] As hybrid electric and / or electric vehicles become more popular, chargers for charging the batteries on these vehicles also become more popular. The plug-in charger is in electrical communication with a power source and is more prone to a possible undesired thermal event since an electrical circuit breaker in electrical communication with...
