The at least one battery cell stack may include a plurality of battery cells arranged one after another along a stack direction. The plurality of battery cells may be arranged within the module housing such that a coolant flowable through the module housing directly contacts the plurality of battery cells. A locking mechanism may form-fittingly connect the at least one battery cell stack to the module housing via (i) a plurality of housing-side locking points and (ii) a plurality of stack-side locking points.

A Universal Battery Pack (UBP), electric vehicle powertrain design and battery swapping network with battery health management enabling a user of an electric vehicle to access data such as state of health monitoring to enable advanced interface with the electricity grid to address challenges in the adoption of electric vehicles which include cost, range anxiety, charging time and infrastructure, and impacts of vehicle to grid (V2G) operations. The electric vehicle powertrain design is equipped with swapping capability, the modular swappable battery packs, battery storage apparatus, and the bidirectional charging systems. The present invention discloses a method for monitoring, assessing and controlling the battery pack and charger, and the communication interface between the systems and the electricity grid and across the battery swapping network. The present invention provides a cost-effective way of adopting electrification, reducing strain on the electricity grid during peak periods and extending the life of electric vehicle batteries.

An arrangement of a structural element for an aerospace vehicle and a battery set. The structural element extends along a longitudinal direction and has a main web, a first flange and a second flange. The flanges extend away from the main web and are defined by flange edges extending along the longitudinal direction. The first flange, the second flange and the main web form a U-shaped profile defining a cavity. The battery set includes a baseplate and at least one battery on the baseplate. The structural element and the battery set are formed such that the baseplate can be releasably attached to the structural element. The baseplate extends between flange edges and the battery is received in the cavity when the battery set is mounted to the structural element. Further, an aerospace vehicle including such an arrangement, a structural element for an aerospace vehicle and a battery set are disclosed.

A movable battery replacing platform includes a travel-driving portion used for driving the movable battery replacing platform to move on the ground; a lifting portion mounted on the travel-driving portion, for lifting a battery during the replacement of the battery; and a battery mounting portion mounted on the top of the lifting portion, for placing a battery to be replaced or a replaced battery. The battery mounting porting is provided with a battery replacing device. The device can use an unlocking device to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The angle of an upper board relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform remains still.

The present invention relates to a method for moving a heavy object into a confined space. The method comprises providing the heavy object in an initial position, the heavy object having an underside resting on a ground surface and comprising an inducible gas-cushion arrangement which in its inactive state causes the underside of the heavy object to maintain contact with the ground surface; activating the inducible gas-cushion arrangement by forming a gas cushion between the underside of the heavy object and the ground surface, the gas cushion generating a lifting force causing the underside of the heavy object to lose contact with the ground surface; moving the heavy object relative to the confined space until the underside of the heavy object at least levels with the supporting surface of the confined space; and moving the heavy object into its final position utilizing the lifting force of the gas-cushion.

The present disclosure relates to a battery assembly for a vehicle comprising a pair of longitudinally extending frame rails, the battery assembly comprising a first and a second vehicle battery module, the first vehicle battery module being stacked vertically on top of the second vehicle battery, wherein the battery assembly is configured to be connected to the vehicle vertically below the frame rails by attaching an upper surface of the first vehicle battery module to a horizontally extending portion of a pair of brackets, the pair of brackets being attachable to a respective one of the longitudinally extending frame rails.

A battery frame that supports a bottom of a battery pack mounted under a floor panel includes a plurality of first cross members extending along the vehicle width and having opposite ends coupled to the floor side members to thereby support the bottom of the battery pack, a second rear cross member coupled with a rear cross member and extending along the vehicle width to support the bottom of the battery pack, and first side members and second side members extending along the vehicle length and coupled with the first cross members and the second rear cross member. The first side members and the second side members are disposed such that their edge lines are connected along the vehicle length.
