An in-vehicle battery module includes a plurality of cylindrical battery cells, a battery cell holder, a protective case, a vent cover provided such that the battery cell holder is positioned between the protective case and the vent cover, the vent cover and the battery cell holder disposed such that a vent space in which gas discharged from an end face on a second-electrode side of the cylindrical battery cell flows is provided between the vent cover and the battery cell holder, at least one first-electrode bus bar, at least one second-electrode bus bar provided in the vent space, and a support member disposed partially in the vent space and the support member being configured to support the second-electrode bus bar from the vent cover side.

A battery module includes battery packs. Heat may be efficiently dissipated from the battery packs of the battery module, and heat dissipating efficiency may not vary according to positions of the battery packs; that is, heat may be uniformly dissipated. In addition, leakage of a cooling medium for dissipating heat may be prevented, and permeation of the cooling medium into the battery packs may be prevented.

Provided is an energy storage device which includes: an electrode assembly where electrodes are layered to each other; and current collector joined to the layered electrodes in a state where the current collector overlaps with the electrodes. The electrode and the current collector are welded to each other or are joined to each other by ultrasonic bonding at a first joint portion. At least one of the electrode and the current collector includes a wall surface which projects from a periphery of the first joint portion or a region adjacent to the periphery along a stacking direction of the electrode and the current collector, and surrounds the first joint portion. The wall surface is disposed on both sides of the first joint portion in the stacking direction.

A battery retention system is configured to facilitate insertion and removal of batteries from an electronic device. The electronic device includes a housing that defines a battery cavity for receiving a battery. The battery cavity has a floor. A floor contact extends from the floor. The floor contact is configured to provide a biasing force to push the battery away from the floor of the battery cavity. The housing has tabs extending into the battery cavity to hold the battery in the battery cavity against the biasing force of the floor contact. The battery cavity has a recess that allows the battery to move in a lateral direction along the floor to a position where the battery disengages from at least one of the tabs to allow at least a portion of the battery to be pushed out of the battery cavity by the biasing force of the floor contact.

An insulation system for a vehicle includes a vehicle component that operates at an operating temperature that is higher than an initial temperature, an insulation member thermally coupled to the vehicle component and thermally coupled to an ambient medium, the insulation member including an enclosed chamber, the enclosed chamber including a chamber wall that defines an interior volume, and carbon dioxide positioned within the interior volume of the enclosed chamber, where the chamber wall prevents flow of the carbon dioxide out of the enclosed chamber.

An electrical equipment cabinet includes a plurality of walls defining an interior of the electrical equipment cabinet, a battery carrier positionable within the interior of the electrical equipment cabinet, and a plurality of batteries attached to the battery carrier via adhesive to substantially prevent removal of the plurality of batteries from the battery carrier. Other example electrical equipment cabinets, battery carriers, etc. are also disclosed.

Disclosed is a modular electrical energy storage and supply system configured one or more transportable unit for relocating the system from one site location to another site location. The system includes energy storage modules, energy conversion unit, monitoring and control units, one or more energy storage module interconnection interfaces, and other peripheral electrical components arranged spatially separated, securely enclosed, and uniformly distributed within the one or more transportable unit for facilitating transportation and customization of the system. Further, presented is a differentiated system and method for rapidly deploying energy storage in grid-tied, off-grid, backup or other use cases.

The invention relates to a device which equips a vehicle that includes a removable container, the device comprising at least one mechanism allowing to clamp the container onto the said vehicle and allowing also to release the container from the said vehicle, by driving a screw or a bolt, screwing to clamp on and unscrewing to unclamp.

A removable battery fixing assembly of an electric vehicle includes a removable battery module and a fixing device installed in the electric vehicle. The removable battery module has a main body with first and second side surfaces. A guiding bar is disposed on the first side surface. The fixing device includes a base, a driving part, a main transmission part, a guiding part, a first stopping part, and a second stopping part. When installing the removable battery module, the guiding bar is aligned with and moved along the guiding part. When moving the removable battery module to a specified position, the driving part drives the main transmission part horizontally, so that the first stopping part is correspondingly rotated to urge against an end part of the guiding bar. Meanwhile, the plural connection elements correspondingly drive the second stopping part to lock the second side surface of the removable battery module.
