Described are remote command-enabled battery modules and systems and methods incorporating them.

Disclosed is an advanced battery module comprising a feature for the restraint of cell swelling. In particular, disclosed is an advanced battery module for a vehicle, comprising a housing having a first wall, second wall, third wall, and fourth wall wherein the first wall is perpendicular to the second wall and fourth wall, and the third wall is parallel to the first wall, wherein the first wall comprises a first wall member, a second wall member parallel to the first wall member, and a plurality of first wall cross-members extending between the first wall member and second wall member; wherein the plurality of first wall cross-members are angled relative to the first wall, at least the first wall and the third wall comprising a plastic; and a plurality of cells.

The disclosure relates to a casing for accommodating battery module and a battery pack. The casing comprises: a housing comprising a bottom plate and a side plate connected to the bottom plate, wherein the bottom plate and the side plate enclose an accommodating space, and the bottom plate is provided with a plurality of recesses opening to the accommodating space; and a buffer assembly comprising at least a first buffer member, which is disposed corresponding to the recess. In the casing for accommodating battery module according to the disclosure, when the battery module is received in the casing, the buffer assembly is located between the battery module and the bottom plate.

A battery includes a case having a feedthrough port, a feedthrough assembly disposed in the feedthrough port, and a cell stack disposed within the case. The feedthrough port includes an inner conductor and an insulator core separating the inner conductor from the case. The cell stack includes an anode, a cathode, and a separator insulating the anode from the cathode, wherein the anode and cathode are offset from one another. An insulating boot surrounding the cell stack insulates the cell stack from the case. The insulating boot has an opening configured to receive therein the feedthrough assembly, which may include overmolded insulation. The interior surfaces and interior walls of the battery case may be thermal spray-coated with a dielectric material to prevent lithium dendrite formation between cathode and anode surfaces.

A vehicle body member includes a first cell unit including a first negative electrode part and a first positive electrode part, a second cell unit including a second negative electrode part and a second positive electrode part, a reinforcing insulating layer interposed between a first surface of the first cell unit and a second surface of the second cell unit, a first positive electrode current collector connected to the first positive electrode part, a second positive electrode current collector connected to the second positive electrode part and connected in parallel to the first positive electrode current collector, a first negative electrode current collector connected to the first negative electrode part, and a second negative electrode current collector connected to the second negative electrode part and connected in parallel to the first negative electrode current collector.

Monobloc batteries include compartments containing cells. Terminals extend into the compartments and are electrically connected with the cells via tabs. The tabs are folded to form bent stacks and include openings in partial registration with each other. The terminals extend through the openings and are secured to the tabs. The terminals are off-center relative to the compartments to preserve space for the bent stacks.
