The disclosure is directed to methods and systems for provisioning mobile electric vehicles with various operational settings data transmitted over the air. A vehicle or its components may operate according to operational settings corresponding to operational settings data included in the vehicle components. A server that is remote to the vehicle may comprise operational settings data and may transmit operational settings data to the vehicle. The server may transmit operational settings data automatically, such as on a periodic basis, in response to a request, such as from a user or from a vehicle component or anytime new or updated operational settings data are available for the vehicle or its components.

A battery case for an electric vehicle includes a main body in which a loading region is partitioned off for loading a plurality of battery modules, a sidewall frame forming a sidewall edge portion of the main body and extending upwards, the sidewall frame including a curving portion to correspond with a shape of a vehicle body adopting a multi-link trailing-arm suspension structure, and a first support member and a second support member which are configured to extend from the main body in the longitudinal and transverse directions for partitioning of the loading region.

A vehicle includes a battery system arranged in a central region. The battery system includes corners corresponding to corners of an end of the vehicle, and respective chassis components are arranged at each corner. Respective shear brackets are affixed to the vehicle frame to a respective chassis component. The shear brackets are configured to absorb energy from the chassis components during deceleration events. The chassis components may include a knuckle configured to engage with the frame at an interface, to which the shear bracket may be added. Each shear bracket is formed from metal, such as sheet metal, and includes mounting features such as holes or studs to affix to the frame. The shear brackets are configured to limit intrusion of the chassis components into the battery system by absorbing energy. A bolt or fastener affixing a chassis component to the frame is strengthened by the shear bracket.

A battery pack for a vehicle is provided. The battery pack comprises: at least one battery module including a plurality of secondary battery cells, a metal framework for supporting the at least one battery module, the framework including a plurality of slots extending from a bottom side to an opposing mounting side of the battery pack, and an insert tightly positioned within each slot, the insert being made of a similar material as the framework and including a through-hole adapted for accommodating a fixation element.

A battery case structure for an electric vehicle, includes a side member in which a flange of the side member laterally provided in a battery case is deformed or broken from a partition to absorb an impact when a side collision occurs, minimizing the impact which is caused by the collision and is provided to penetrate into a battery. Furthermore, the partition of the side member is designed based on topology optimization to secure rigidity, protecting the battery against the impact.

A modular electrical Energy Storage System structure for powering an electric motor in a vehicle. The modular ESS structure includes two or more electrical energy storage modules, the modular ESS structure extending in a longitudinal direction, in a transverse direction and in a vertical direction, the longitudinal direction coinciding with a driving direction of the vehicle, the two or more electrical energy storage modules being arranged side-by-side in the transverse direction , in the longitudinal direction and/or in the vertical direction and being connected to each other structurally and electrically. The modular ESS structure comprises a first mounting interface comprising one or more first connecting members configured for mounting to a vehicle structure.

The invention relates to a compartment for equipment likely to emit heat during its operation, in particular for a device for storing electrical energy for a motor vehicle, said compartment having at least one cooling plate arranged to have a cooling fluid flowing through it and arranged to cool said equipment. The compartment further includes an upper housing arranged to accommodate said electrical equipment, and a lower housing, in which at least one fluid connection element is placed in order to supply the cooling plate with fluid, the lower and upper housing being isolated from each other in a fluidly sealed manner.

An electric powered vehicle including a traction motor is disclosed. The vehicle may further include a body including a cabin and a front body; a subframe mounted at a lower portion of the front body and supporting a suspension along with the front body; and a battery unit mounted a t a lower portion of the cabin and configured to supply electric power to the traction motor. The subframe may include a side rail extending in front-rear directions of the electric powered vehicle and is secured to a rail mount portion of the body at a rear end of the side rail. The battery unit may include a bracket projecting in a front direction of the front-rear directions and is secured to the rail mount portion of the body at the bracket.

A fuel cell vehicle is provided and includes a system frame on which a fuel cell is mounted and first and second side members extending in a first direction and facing each other in a second direction intersecting the first direction. A first fastening part fastens the system frame to each of the first and second side members. The system frame includes a first aperture formed therein in a horizontal direction. The first fastening part includes a first support bracket, including a second aperture, a first insertion hole, and a first tab portion extending from the first insertion hole in the horizontal direction, and a first bolt, including a first shank portion inserted into the first aperture, the second aperture, and the first insertion hole in the horizontal direction and a first threaded portion engaged with the first tab portion.
