Problems solved by technology

Battery trays for known battery-powered and hybrid or battery-engine powered vehicles (hereinafter collectively referred to as "battery-powered" vehicles) provide features that absorb impact loads from the underside and sides of the battery tray to minimize stress on the internal battery cells. damage, however, the structural design of such battery trays often requires complete replacement of the battery tray after minor structural damage occurs, and greatly increases the cost of the battery tray to accommodate the impact load

Embodiment Construction

[0041] The following description is merely exemplary in nature and is not intended to limit the disclosure, application, or uses.

[0042] refer to figure 1 , the vehicle battery system 10 includes a battery cell or battery tray 12 that is structurally mounted to the vehicle 14 . The battery tray 12 includes a basin 13 for receiving within the basin 13 at least one battery cell and, according to several aspects, a plurality of individual battery cells that provide electrical charge as the sole power for propelling the vehicle 14, or in addition to In addition to the engine, supplementary power is also available. The basin 13 is preferably formed as a unitary unitary structure, eg, by stamping or drawing from sheet metal, to form the entire basin 13 . The tub 13 also includes an upper flange 15 extending outwardly from the upper end of the tub 13 for attaching the tub 13 to a cover (not shown) or to a side member of the tub 13 .

[0043] refer to figure 2 , and again refer...

Abstract

A battery tray for a battery powered vehicle includes a battery tray having side walls. The impact absorbing structure is attached to the side wall. The impact absorbing structure includes at least one roll-formed member secured to the sidewall. The at least one roll-formed member is made from a single sheet metal and includes a first plate portion that is roll-formed to form a first cavity and has a center wall of the member formed in the first plate portion of the first flange. The first flange is secured to the first plate portion. The second plate portion is roll formed to form the second cavity and has a second flange at the end of the second plate portion secured to the central wall of the member. A roll-formed U-shaped attachment member is secured to the at least one roll-formed member.

Description

technical field [0001] The present disclosure generally relates to energy absorbing structures in battery trays for battery powered vehicles. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Vehicles that rely at least in part on battery-powered propulsion, including electric and hybrid vehicles, create unique conditions; due to the energy and fluids in the battery cells, these conditions must be accounted for in order to absorb structural impacts without damage battery unit. Known battery trays for battery powered and hybrid or battery engine powered vehicles (hereafter collectively referred to as "battery powered" vehicles) provide features for absorbing impact loads from the underside and sides of the battery tray to minimize damage to internal battery cells. Damage, however, the structural design of such battery trays often requires a co...
