The base 31 is detachably connected to the frame 1, all the tie rods 32 are spaced apart on the base 31 along a first direction (the first direction is the illustrated X direction), and all the tie rods 32 extend along a second direction (the second direction is the illustrated Y direction), and the tie rods 32 are connected to connecting cables serving to connect the battery packs, and the first direction is disposed at an angle to the second direction. The connection cable of the battery pack includes a charge control cable, a connection cable between positive and negative terminals, a temperature control cable, and a communication cable, as well as other cables connected to an external mechanism. When the cable tie member 3 is disposed on the battery holder corresponding to each layer of support plates 2, the first direction is parallel to the vertical direction; when the cable tie member 3 is disposed on the upper surface of the battery holder, the first direction, the second direction, and the vertical direction are perpendicular to each other.By disposing the cable tie member 3 with cable tie rods 32 on the battery holder, the connection cables of each of the battery packs can be connected to the cable tie rods 32 and disposed in the length direction of the cable tie rods 32, so that the plurality of connection cables are laid out and arranged orderly in an orderly manner, which is practical for later-stage maintenance and is considered practical.

The peripheral plate 4 is provided with through holes, the frame 1 is provided with threaded holes, and a bolt is screwed into the threaded holes through the through holes to connect the peripheral plate 4 to the frame 1. The screw connection is stable and convenient for disassembly and assembly, and of course the peripheral plate 4 can also be connected by means of a push button arranged on the peripheral plate 4 to a slot arranged on the frame 1, and the push button is connected to the slot in the form of a snap connection. It is understood that by disposing the peripheral plate 4, the battery pack placed on the support plate 2 on the peripheral side can be effectively protected and locked, thereby avoiding damage caused by external structures hitting the battery pack or preventing the battery pack from slipping off the support plate 2, and improving safety of use of the battery pack on the support plate 2.As illustrated in FIG. 2, the peripheral plate 4 includes a fixing portion 41 and a stopper portion 42, the fixing portion 41 is detachably connected to the frame 1, and the fixing portion 41 is provided with the stopper protruding portion 42 on a side facing the battery pack, the arrangement of the stopper portion 42 prevents the battery pack from coming off the mounting slot 5. By disposing the stopper portion 42, it is possible to effectively stop the top surface of the battery pack, reduce the jumping of the battery pack, and improve the stability of the battery pack installation.In another embodiment, as shown in FIG. 1, the battery holder includes at least two frames 1 and a connecting member, and two adjacent frames 1 are detachably connected by the connecting member. By the arrangement of the connecting member, the plurality of frames 1 can be connected to each other, so that the plurality of frames 1 can be assembled into battery holders having different battery capacities, whereby the battery holders can meet the requirements of various scenarios and the versatility of the battery holders is increased. In this embodiment, the frame 1 is provided with a plurality of extension holes at intervals, the extension holes are threaded holes, at least two rows of through holes are disposed on the connector, and bolts are screwed through the through holes into the extension holes to connect the connector to the frame 1, and two adjacent frames 1 are connected by the connector to complete the extension of the battery holder.As shown in FIG. 1, the battery holder comprises, for example, two frames 1, the edges of the two frames 1 being aligned with each other. At this time, the connector includes a connector, and installation of the battery holder including two frames 1 can be completed by using the connector to connect the extension holes of the frames 1. When the battery holder includes four frames 1, as illustrated in FIG. 7, the connector includes a connector, a connector block 6, and a reinforcing connector post 7, and the four frames 1 are first divided into two frame groups each including two frames 1, and the two frames 1 of each of the frame groups are connected by the connector. The two frame groups are spaced apart from each other, and the two frame groups are connected at the outermost side of the frames 1 by the connection block 6, and a reinforcing connection post 7 is provided in a spaced area in the two frame groups, and the reinforcing connection post 7 is connected to the frame 1 adjacent to the reinforcing connection post 7 in the two frame groups to reinforce the connection strength between the two frame groups.

Therefore, the partition wall can directly use a partition plate having high flame retardancy.In the supporting plate 2, a liquid cooling passage is disposed, which is connected to the external circulation mechanism via a liquid inlet pipe and a liquid outlet pipe bonded on the pull wire 32. By combining the support plate 2 with the liquid cooling structure, the structure of the support plate 2 is capable of cooling the battery pack in addition to supporting the battery pack with liquid, reducing the arrangement of the conventional liquid cooling plate, thereby reducing the space occupied by the liquid cooling plate and effectively improving the space utilization of the battery holder. For example, the external circulation mechanism transfers the coolant through the liquid inlet pipe into the liquid cooling channel for heat exchange, and the coolant having a certain temperature after the heat exchange is transported through the liquid outlet pipe back to the external circulation mechanism to perform liquid cooling again to complete the continuous liquid cooling of the liquid cooling plate and ensure the liquid cooling effect of the battery pack.The battery mount further includes a cable tie seat, and the cable tie rod 32 is spaced along its length by a plurality of cable tie seats. The cable tie seats are arranged such that the connecting cables can achieve a fixed point bundling, i.e. the connecting elements can be bundled on the cable tie seats with the aid of the bundling strap, which reduces the slipping of the bundling strap and ensures the stability of the connecting cables and the connecting position of the cable tie rods 32.
