A battery submodule carrier includes a monolithic cell tray configured to accommodate a plurality of aligned battery cells; a plurality of cell retainers configured to retain the battery cells within the cell tray; and a plurality of tray fasteners configured to mount the cell tray to a battery system carrier.

A battery for a vehicle having a fixed battery pack and a replaceable battery pack. The replaceable battery pack has electronic or mechanical locks to semi-temporarily hold the replaceable battery pack in place. The fixed battery pack is held in place via permanent or semi-permanent fasteners such as bolts. A battery controller controls the replaceable battery pack to power motors of the vehicle before controlling the fixed battery pack to power motors of the vehicle.

A secondary battery module includes a plurality of battery blocks each obtained by stacking a plurality of battery cells. The secondary battery module includes a holding member adapted to hold the plurality of battery blocks and including a pair of opposed end plates, a pair of opposed side plates, and a section plate arranged between the adjacent battery blocks to partition the battery blocks; and an inter-block bus bar provided across the section plate and adapted to electrically connect the adjacent battery blocks. The inter-block bus bar has a fuse portion.

The present invention pertains to a battery housing for receiving battery cells, preferably for use in an electric or hybrid vehicle, the battery housing comprising a bottom plate forming a base of the housing, wherein the bottom plate is connectable to another bottom plate of the same kind by means of a connection system to form a modular bottom of the housing.
