Embodiment Construction

[0058] First refer to figure 1 , the vehicle 1 includes a hybrid propulsion system in the form of a source of electrical power consisting of a conventional ICE 5 and one or more battery packs disposed within a simplified version of the package 10 of the present invention; both the ICE 5 and the battery pack are connected to the electric motor 15 cooperation. Such vehicles are called hybrid electric vehicles (HEVs). It will be appreciated by those skilled in the art that in the case where the vehicle 1 is not an HEV, but an electric vehicle (EV), the vehicle 1 may not need the ICE 5; either form is within the scope of the present invention. Additional driveline components (neither shown) adapted to provide propulsion power to one or more of the wheels and coupled to one or both of the battery pack and ICE 5 are understood to include rotating shafts, axles, transmissions, controller etc. In a preferred form, the motor 15 acts as a load on the battery pack (or packs). Althoug...

Abstract

The invention relates to reconfigurable vehicular battery enclosure components, and specifically relates to a modular battery pack and a method of making a battery pack. Prismatic battery cells are aligned within the enclosure such that reconfigurable adjusting of the enclosure and its components may take place without having to redesign either. In this way, battery packs containing a different number of successively smaller battery modules or battery cells may be placed within the common enclosure. Slidably mountable features of at least some of the components within the enclosure help promote this modularity. The enclosure includes a tray that defines a substantially constant section along a mounting surface that corresponds to a stacking axis of the aligned prismatic cells or modules. Numerous brackets that can help secure the batteries, their electrical leads or components are disposed along a portion of the mounting surface such that the cooperation between the brackets and the mounting surface of the tray is invariant, regardless of where along the elongate dimension the cooperation occurs.

Description

technical field [0001] The present invention relates generally to the housing of the individual battery cells that make up a vehicle battery pack, and more particularly to the use of reconfigurable components that make up a battery package that is adaptable to a variety of vehicle battery pack variants. Background technique [0002] Lithium-ion and related batteries are being used in motor vehicles and related transportation applications, as a supplement in the case of hybrid electric vehicles (HEVs), or as conventional in the case of pure electric vehicles (EVs) Replacement for Internal Combustion Engine (ICE). The ability to passively store energy from stationary and movable sources as well as energy from the recaptured kinetic energy provided by the vehicle and its components enables such batteries to be used as a power source for propulsion systems for passenger cars, trucks, buses, motorcycles and related vehicle platforms. Parts are ideal. In one form suitable for au...
