Filed:

Apr 27, 2018

Appl. No.:

15/965349

Inventors:

- Dearborn MI, US
Kyle Krueger - Dearborn MI, US
Patrick Daniel Maguire - Ann Arbor MI, US

International Classification:

H01M 2/10
H01M 10/42
H01M 10/6554
H01M 10/625

Abstract:

This disclosure details exemplary battery pack designs for use in electrified vehicles. Exemplary battery packs may include a polymer-based enclosure assembly having features for both retaining components and transferring loads inside the battery pack. The battery packs may include one or more snap-in features for retaining the components and one or more foam spacers for separating adjacent battery arrays and establishing a load transfer path inside the battery pack.

Appl. No.:

15/872302

Inventors:

- Dearborn MI, US
Kyle Krueger - Dearborn MI, US
Mohammadreza Eftekhari - Northville MI, US

International Classification:

H01M 2/12
H01M 2/10

Abstract:

An exemplary battery assembly includes, among other things, a battery array, and an expanded polymer-based enclosure that at least partially surrounds the battery array. The expanded polymer-based enclosure includes a vent manifold to communicate gases vented from the battery array. An exemplary method includes, among other things, forming a vent manifold within a polymer-based enclosure. The vent manifold is to communicate gases vented from a battery array. The method further includes at least partially surrounding the battery array with the polymer-based enclosure.

International Classification:

B60W 20/13
H01M 2/10
B60L 11/18

Abstract:

A hybrid electric vehicle having battery packs coupled to the vehicle in parallel, which each include series-connected cells, a single contactor, a battery pack controller that detects cell voltages, and at least one controller coupled to a bus contactor and the packs. Responsive to a vehicle key on signal, the at least one controller closes the single battery pack contactor for at least one of the battery packs that includes voltage balanced cells. The bus contactor is then closed to deliver electrical power to the vehicle, and may include a precharge contactor that is closed in advance of and until the bus contactor open circuit voltage is reduced to a contactor voltage difference. The battery pack controllers are further configured to detect voltage, current, and temperature of each cell, to open the single contactor, and to adjust the state of charge of unbalanced cells until balanced relative with the others.
