Patent number: 11837692Abstract: A battery pack (1) includes a housing (2) and an array of electrochemical cells (80) disposed in the housing (2). The housing (2) includes a container (3) and a lid (30) that closes an open end of the container (3). The container (3) has a base (4), a sidewall (8) that surrounds the base (4), and a spring plate (110) disposed inside the sidewall (8) between the cells (80) and the sidewall (8). The spring plate (110) is free standing within the container (3) and applies a spring force to the cell array that restrains the cells (80) along an axis normal to the surface of the spring plates (110). The lid (30) includes inwardly-protruding pins (50, 60) that further restrain the cells (80) within the housing (2).Type: GrantFiled: September 29, 2017Date of Patent: December 5, 2023Assignees: Robert Bosch Battery Systems GmbH, Robert Bosch GmbHInventors: Kecheng Xu, Alexander Foitzik, David Nietling, Henrik Wolfgang Behm, Klaus Spieske, Kyle Schultz, Mehul Botadra, Rainer Menig, Robert Kohler, Ruben Jung, Sinasi Temiz, Walter Jasch, Martin Kassner

Patent number: 11658360Abstract: A battery pack includes a housing and electrochemical cells disposed in the housing. The housing includes a container and a lid that closes an open end of the container. The container has a base, an outer wall the surrounds the base, and a first and a second inner wall disposed inside the outer wall. The first inner wall extends between, and is fixed to, a first portion and a third portion of the outer wall, and is spaced apart from a second portion and a fourth portion of the outer wall. The second inner wall extends between the first portion and the third portion, and is disposed between the first inner wall and the fourth portion. The second inner wall is movable relative to the outer wall such that spacing of the second inner wall from the first inner wall can be changed.Type: GrantFiled: July 20, 2020Date of Patent: May 23, 2023Assignees: Robert Bosch Battery Systems GmbH, Robert Bosch GmbHInventors: David Nietling, Kyle Schultz, David Naughton, Mehul Botadra, Ruben Jung, Walter Jasch, Stefan Grun, Lisa Lorenz

Publication number: 20220158291Abstract: A battery module includes an array of electrochemical cells, and a frame configured to support the cells within the battery module, the fame encircling the array in such a way as to overlie the cell sidewall of each cell and expose the cell first end and the cell second end of each cell. The frame is surrounded by a spacer. The spacer includes a first wall portions that faces the cell first ends, and a second wall portion that faces the cell second ends. The first and second wall portions include grooves that serve as coolant fluid passages. The frame is disposed in the spacer interior space in such a way that each of the cell first ends and each of the cell second ends are exposed to the fluid passages of the first wall portion and the second wall portion.Type: ApplicationFiled: March 29, 2020Publication date: May 19, 2022Inventors: Paul Frick, Mehul Botadra, David Nietling, Michael Marchio, Michael Marra, Mark Kotik, Kevin Mitchell Lynk

Patent number: 10381615Abstract: A battery module comprises an electrochemical cell including a first dielectric layer positioned on a first side of the cell, a first side plate in opposition to the first side, and a first adhesive layer positioned between the first side plate and the first side. The first dielectric layer defines a first window. The first adhesive layer is adhered to the first side plate and the first side through the first window. Another battery module comprises first and second cells, a base plate, a frame, and a first and second adhesive portion. The frame includes a beam positioned between the first cell and the second cell and is in engagement with a first side and a second side of the first and second cells, respectively. The first adhesive portion and the second adhesive portions are positioned between the base plate and the bottom surfaces of the cells.Type: GrantFiled: June 19, 2015Date of Patent: August 13, 2019Assignee: Robert Bosch GmbHInventors: David Nietling, Christopher Matthew Millon, David Brian Naughton

Patent number: 10224528Abstract: A battery module includes a battery module housing, cells disposed in the battery module housing, and spacers disposed between adjacent cells. Each spacer is electrically insulating and includes a body portion having a curvilinear, for example elliptical, outer peripheral shape. The body portion is suspended from the cell housing by hangers, and overlies a central region of a cell housing surface corresponding to large deflection due to cell growth. In addition, the body portion is spaced apart from a periphery of the cell housing surface.Type: GrantFiled: June 17, 2016Date of Patent: March 5, 2019Assignees: Bosch Battery Systems LLC, Robert Bosch GmbHInventors: David Nietling, Mehul Botadra, Kyle Schultz
