A cooling plate for a battery pack with a plurality of battery cells is provided. The cooling plate includes a cooling fin with a substantially planar surface and a perimeter. The cooling plate includes a frame abutting the cooling fin and forming a seal with the cooling fin adjacent the perimeter of the same. The frame and the cooling fin define at least one fluid inlet, at least one fluid outlet, and a flow channel therebetween. The at least one fluid inlet and the at least one fluid outlet are disposed through the seal and are in fluid communication with the flow channel. The flow channel is disposed adjacent the perimeter and in heat transfer communication with the substantially planar surface of the cooling fin. A battery pack with the cooling plate, and a method for controlling a temperature of the battery pack, are also provided.

A foot cover assembly comprising a foot cover and a base plate is disclosed. The foot cover releaseably attaches to the base plate. The base plate releaseably attaches to a board assembly. A portion of the foot cover is arranged over a deck of the board assembly. The foot cover selectively holds a foot of a rider of the board assembly between the foot cover and the deck.

Skateboard truck system and method

Exemplary embodiments include method of sealing battery cooling plates, and methods of assembling battery using battery cooling plate racks and a single component including multiple cooling plates and connection portions therebetween.

Batteries and components thereof and methods of making and assembling the same

A molded cooling fin and frame is described. The molded cooling fin and frame includes a corrugated center cooling fin; a pair of outer cooling fins on opposite sides of the corrugated center cooling fin, each of the outer cooling fins having a ridge around an edge; and a frame covering an edge of each of the outer cooling fins, the frame sealed to the edge of each of the outer cooling fins. A battery pack including the molded cooling fin and frame and a method of making the molded cooling fin and frame are also described.

An exemplary embodiment includes a method of sealing battery cooling plates.

A battery pack is described. One embodiment of the battery pack includes a pair of end frames, the end frames having a top and a bottom and a pair of sides, the end frames having a detent on at least one of the sides of the end frames to receive a clamp; a frame positioned between the pair of end frames, the frame having a top and a bottom and a pair of sides, the frame having a ridge on at least one of the sides of the frame; a plurality of battery cells positioned in the frame and the pair of end frames, the plurality of battery cells electrically connected to each other at the top of the frame; and at least one cooling fin positioned between the battery cells. Methods of repairing battery packs are also described.

Modular battery design

One exemplary embodiment including a battery cooling plate has discrete channels. In one exemplary embodiment each of the channels has a width ranging from about 1 mm to about 5 mm. In another exemplary embodiment the battery cooling plate includes a first cooling channel having a flow path generally in a U shape, and a plurality of other channels each having a generally U-shaped flow path, and wherein the other flow channels are in a nested position with respect to the first flow channel. In another exemplary embodiment the battery cooling plate a battery cooling plate includes a serpentine shaped cooling flow path formed therein, the cooling flow path including a first cooling segment and an adjacent upstream second cooling segment, wherein the second cooling segment includes at least a first cooling channel and a second cooling channel and at least a first land interposed between the first cooling channel and second cooling channel, and wherein the second cooling segment has at least one more land and one more channel than the first cooling segment.
