This disclosure is directed toward traction battery packs that include energy absorbing structures for protecting the internal contents of the battery pack. An exemplary battery pack may include an enclosure assembly and one or more battery arrays that are housed within the enclosure assembly. The enclosure assembly includes an energy absorbing structure that may include a plurality of fluid filled unit cells. The stiffness of each fluid filled unit cell may be controlled by allowing fluid to be released from the unit cells during vehicle impact events, thereby absorbing impact energy that could otherwise be imparted inside the battery pack.

A method and system for swapping batteries in an electric vehicle is disclosed. The method includes dismounting a first battery assembly, moving to a second battery assembly and mounting the second battery assembly onto the vehicle. Mounting and dismounting are accomplished by an onboard mounting and dismounting system. The method can be used in a zero infrastructure environment such as an underground mine since mounting and dismounting are accomplished by components on the vehicle itself. An auxiliary battery pack powers the vehicle during between dismounting a battery pack and mounting another battery pack.

An energy storage system for vehicles is provided which is formed by a battery and a compartment for its accommodation which allows the insertion and removal of batteries and their connection to the electrical system of the vehicle with ease, quickly and at a low cost, both manually and based on auxiliary tools with different degrees of automation; the battery includes electrical connection elements and communication connection elements and is inserted in or removed from the compartment with a horizontal movement. The compartment includes electrical connection elements and communication connection elements complementary to those of the battery and allows cooling the battery; in this way, an electric vehicle can incorporate batteries as needed, adjusting its cost to its real use and reducing the waiting times due to charging its energy storage.

This disclosure details electrified vehicles that are equipped with one or more attachment and sealing assemblies for securing a battery pack to the vehicle. An exemplary attachment and sealing assembly may establish a mid-span attachment point of the battery pack and may include a pass-through component, a fastener, and a seal. The fastener may be positioned relative to the pass-through component using either a bottom-up or top-down approach. The seal may radially seal between a portion of a battery pack enclosure assembly and the pass-through component.

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.

A vehicle includes a chassis, tractive elements coupled to the chassis, an electric motor coupled to the chassis and coupled to the tractive elements such that the electric motor drives the tractive elements to propel the vehicle, an accessory module coupled to the chassis and coupled to an output of the electric motor. The accessory module is configured to receive mechanical energy provided by the electric motor and provide at least one of electrical energy or fluid energy.

A high voltage battery carrier for a vehicle includes: a main carrier coupled to a vehicle body frame and fixed to a high voltage battery; a subcarrier coupled to an upper portion or a lower portion of the main carrier and configured to form a space in which an electrical and electronic part is accommodated when coupled to the main carrier; and a detachable carrier which is vertically detachably installed on the subcarrier. The electrical and electronic part is coupled to the detachable carrier. With this arrangement, installation space can be reduced and workability is improved due to easy attachment and detachment of the electrical and electronic part.

A battery storage arrangement for a working device, in particular for a vehicle, includes a battery storage and a carrier. The carrier has a monolithic screwing area having a thread. The battery storage is fastened to the carrier by way of a threaded fastener via the screwing area.

A battery pack replacement and explosion-proof system: Start to control the second battery pack robot system and the ferry robot to uninstall and install the first battery pack and the second battery pack; the second connection point of the first power supply protector's grounding conductor unloads and absorbs the large current entering along the first power line; the third connection point unloads and absorbs the large current along the second power line; the fifth connection point of the second power surge protector unloads and absorbs the large current along the third power line; the sixth connection point unloads and absorbs the large current along the fourth power line; the first connection point and the fourth connection point unloads and absorbs the large current along the first and the second control line and signal lines of BMS, various parts of the grounding conduct currents into the earth through the conductive tyre.

A body floor structure (1) for a motor vehicle having a traction battery (2) includes a first longitudinal member (3) and a second longitudinal member (4) that extend in a vehicle longitudinal direction. A floor panel (5) spans between the two longitudinal members (3, 4). A central tunnel (6, 6) extends in the vehicle longitudinal direction and has a cavity (60, 60) and is configured for receiving equipment components of the motor vehicle. The traction battery (2) is arranged on a lower side of the body floor structure (1), and the cavity (60, 60) of the central tunnel (6, 6) is designed to be open in the direction of a vehicle interior (7).
