The module housing can be flowed through in particular directly by a coolant, such that the battery cells in the interior come directly in contact with the coolant. The battery module has a locking device, which secures the battery cell stack within the interior in a form-fitting manner at least to one of the housing parts, in particular to the first housing part. The disclosure also relates to a traction battery for a battery electric vehicle with the battery module.

A battery module for a traction battery may include a module housing through which a coolant is flowable and at least one battery cell stack arranged within an interior space of the module housing. 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 driving device unit includes an electric motor configured to drive a vehicle, a drive device accommodating the electric motor, and an electric motor control device configured to control the electric motor. The drive device and the electric motor control device are arranged side by side in a horizontal direction, and an electrical connection portion electrically connecting the drive device and the electric motor control device is disposed at a joining portion between the drive device and the electric motor control device, and the drive device and the electric motor control device include a first fixing portion that directly fixes the drive device and the electric motor control device in the vicinity of the electrical connection portion, and a second fixing portion that fixes the drive device and the electric motor control device via a stiffener at a position away from the electrical connection portion.

An accumulator arrangement for a motor vehicle may include a receiving space configured to receive at least one battery module, a supply arrangement arranged in the receiving space, and a protective cover at least partially closing the receiving space. The supply arrangement may be configured to supply the at least one battery module. The receiving space may be defined by a recess disposed in a chassis of the motor vehicle. The supply arrangement may be formed directly on an underside of the chassis. The supply arrangement may have at least one first interface operatively connected to the at least one battery module via at least one second interface of the battery module. One of the at least one first interface and the at least one second interface may be insertable into the other one of the at least one first interface and the at least one second interface.

Disclosed are a movable battery replacing platform (103) and a quick replacing system (100), wherein the movable battery replacing platform (103) comprises: a travel-driving portion (106) used for driving the movable battery replacing platform (103) to move on the ground; a lifting portion (107) mounted on the travel-driving portion (106), for lifting a battery during the replacement of the battery; and a battery mounting portion (108) mounted on the top of the lifting portion (107), for placing a battery to be replaced or a replaced battery, wherein the battery mounting porting (108) is provided with a battery replacing device. The device can use an unlocking device (50) 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 whole process is fully automated without manual intervention and can improve battery replacement efficiency. In addition, the angle of an upper board (10) 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 (103) remains still, so as to further improve unlocking efficiency.

A tractor trailer battery system having a battery compartment containing one or more battery units which house one or more battery cells, electrical leads from the battery units to a trailer mounted controller in electrical communication with a cab mounted controller which is in electrical communication an electric motor or hybrid engine system. The battery system allows for either the trailer mounted controller or the cab mounted controller to provide principal communication to the electric motor or hybrid engine system.

A battery assembly for installation into a battery structural space of a transportation vehicle body having a battery housing accommodating a number of battery modules, wherein the battery housing has a smaller dimension along a vehicle longitudinal direction than the battery structural space, such that a free space is formed in the battery structural space, and wherein a shear panel element is provided as an areal bridging and stiffening of the free space.

A cooling structure of a vehicle battery unit includes: a plurality of battery modules; a plurality of battery cooling units; a supply pipe; a discharge pipe; and a battery case.
