Embodiment Construction

[0038] figure 1 is a perspective view of a vehicle 10 in the form of an automobile (eg, a car) with a battery system 20 for powering all or a portion of the vehicle 10 . Such vehicles 10 may be electric vehicles (EVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), or other types of vehicles that employ electrical energy for propulsion (collectively referred to as " electric vehicles").

[0039] Although the vehicle 10 is in figure 1 is shown as a car, but the type of vehicle may vary according to other exemplary embodiments, all of which should fall within the scope of the present disclosure. For example, vehicle 10 may be a truck, bus, industrial vehicle, motorcycle, recreational vehicle, boat, or any other type of vehicle that may benefit from the use of electrical energy for all or a portion of its propulsion power.

[0040] Although the battery system 20 is in figure 1 The battery system 20 is shown in the trunk or rear of the vehicle, h...

Abstract

An electrochemical cell includes a housing having a first end and a vent located at the first end that is configured to deploy from the housing to allow the expulsion of gases from within the cell. The electrochemical cell also includes at least one projection extending outward from the first end adjacent the vent. The at least one projection is configured to prevent accidental deployment of the vent.

Description

[0001] Cross references to related patent applications [0002] This application claims the benefit and priority of U.S. Provisional Patent Application No. 61 / 169,657, filed April 15, 2009, and U.S. Provisional Patent Application No. 61 / 172,148, filed April 23, 2009, the entire disclosure of which is adopted by References are hereby incorporated. Background technique [0003] This application relates generally to the field of batteries and battery systems. More specifically, the present application relates to batteries and battery systems that may be used in vehicle applications to provide at least a portion of the power for the vehicle. [0004] Vehicles that use electrical energy for all or part of their propulsion (for example, electric vehicles (EV), hybrid electric vehicles (HEV), plug-in hybrid electric vehicles (PHEV) and similar vehicles, which are collectively referred to as known as "electric vehicles") may offer several advantages over more traditional gas-powere...
