Abstract: 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).

Abstract: A method, apparatus, and system according to which a discharge manifold is pressurized by at least a first fracturing pump, said discharge manifold being adapted to communicate pressurized fluid to an oil and gas wellbore.

Abstract: 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.

Abstract: A method, apparatus, and system according to which a swap adapter is connected to a swap station while a discharge manifold is pressurized by at least a first fracturing pump, said discharge manifold being adapted to communicate pressurized fluid to an oil and gas wellbore. The swap adapter is connected to a second fracturing pump via a first suction conduit and a first discharge conduit. The swap station is connected to a suction manifold via a second suction conduit. The swap station is connected to the discharge manifold via a second discharge conduit. After connecting the swap adapter to the swap station, and while the discharge manifold remains pressurized by at least the first fracturing pump: fluid is drawn from the suction manifold using the second fracturing pump; and pressurized fluid is discharged into the discharge manifold using the second fracturing pump.

Abstract: 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.
