Embodiment Construction

[0015] Figure 1-2 A vehicle 10 according to a first embodiment is illustrated. Vehicle 10 includes a passenger compartment 12, a front 14 containing an engine, electric motor or fuel cell (not shown), and a rear 16 which may be a trunk (for a sedan) or a rear trunk ( In the case of a sport vehicle, station wagon or similar type of vehicle) and contains the battery module 18 . The basic vehicle configuration may be hybrid electric, electric or other similar form of vehicle propulsion utilizing battery modules 18 . The battery module 18 may be housed in the trunk of a sedan, or behind the interior of an automobile or under the trunk floor of the rear compartment of a station wagon or sport vehicle.

[0016] Passenger cabin 12 includes front seats 20 and rear seats 22 . A luggage rack 24 (or the trim's trunk floor if not a sedan) is located behind the rear seat 22 and includes a battery module air intake 26 that may be designed to allow flow in only one direction—out of the p...

Abstract

A battery pack cooling and body pressure relief system for a vehicle having a passenger cabin is disclosed. The system may include an intake air flow duct connected between the passenger cabin and the battery pack, and an air flow duct connected between the exhaust air outlet and the body pressure relief valve. The system may include a one-way cabin pressure relief vent connected to the air flow duct and configured to selectively allow for air flow into the air flow duct, and may include a duct pressure relief vent connected to the air flow duct and configured to selectively allow for air flow out of the air flow duct into the vehicle.

Description

technical field [0001] The present invention relates generally to body pressure relief systems for motor vehicles, and more particularly to body pressure relief systems for motor vehicles with battery packs. Background technique [0002] Certain newer motor vehicles are propelled by electric motors, such as fuel cell, hybrid electric or pure electric vehicles. These vehicles include battery packs used to store electrical charge for driving electric motors. There may be a substantial amount of energy flowing into or out of the battery pack, which can raise the temperature of the battery pack to higher than desired levels. Accordingly, some of these vehicles use various techniques to cool the battery pack. Because of the added expense and complexity of cooling the battery pack, it is desirable to cool the battery pack in the most efficient and cheapest possible manner. [0003] Also, because some vehicles are sold with conventional drivetrain arrangements (without a battery...
