A battery pack according to this application includes a lower support; a lower fastening member that is fastened onto the lower support and extending upwards along a height direction; an upper support plate provided above the lower fastening member; and a heat exchange plate directly fastened onto the upper support plate. In the battery pack according to this application, the heat exchange plate is directly fastened onto the upper support plate, which eliminates use of a position locking piece to position the heat exchange plate and ensures that flatness and positioning tolerance of the heat exchange plate are not affected.

Battery pack

The battery pack according to this application includes: a frame body, enclosing an accommodating space that is closed circumferentially and opened in a height direction; and a heat exchange plate, fixed under the frame body and closing a lower opening of the accommodating space. The heat exchange plate includes: a body portion provided with a heat exchange flow passage; and a fastening portion connected to an entire periphery of the body portion and provided with a plurality of notches, where the notches are recessed inward from an end of the fastening portion, the plurality of notches are spaced apart along the entire periphery of the fastening portion, a protrusion is formed between each two adjacent notches, and the protrusion is fixedly connected to the frame body.

Embodiments of the present application relate to the technical field of batteries, and provide a water cooling assembly, a battery pack, and a device in order to solve the technical problem of low cooling efficiency of a cooling assembly of a battery pack. The water cooling assembly is configured to cool a cell, and includes: a body portion having a cooling channel for receiving a coolant; a first connecting portion connected to the body portion and having a communication cavity for introducing or draining the coolant; and a second connecting portion arranged between the body portion and the first connecting portion and having an inner cavity for communicating the cooling channel with the communication cavity. An end face of the inner cavity close to the cooling channel has a cross-sectional area greater than that of an end face of the communication cavity close to the inner cavity.

Water cooling assembly, battery pack, and device

Some embodiments of the present disclosure relate to technical field of the battery cooling technical and provide a battery cooling assembly, including: a cooling tube; a collecting tube, provided with at least one collecting opening; a connecting aid, including a base plate provided with a through hole, and a hole wall of the through hole extends outwardly to form an extension. An end of the cooling tube is connected to the extension through the through hole, the base plate is connected with the collecting tube, and the through hole being in communication with the collecting opening. The battery cooling assembly of the present disclosure can increase the connection strength between the cooling tube and the collecting tube, thereby reducing a risk of leakage of a cooling medium.

Battery cooling assembly

Disclosed are a battery pack cooling system and a battery pack. The battery pack cooling system includes: a cooling pipeline, which is provided inside the battery pack, provided with an inlet and an outlet, and configured to cool a battery module; an inlet connecting pipe, which extends into the battery pack and is connected to the inlet, and is provided with a first fool-proofing structure; and an outlet connecting pipe, which extends into the battery pack and is connected to the outlet, and is provided with a second fool-proofing structure, the second fool-proofing structure being different from the first fool-proofing structure.

Battery pack cooling system and battery pack

A temperature detecting device is provided, which includes a housing, a temperature sensor and a fixed part. A battery pack is further provided, which includes two or more battery cells, a heat exchange tube, and the temperature detecting device. The temperature detecting device is fixed to an outer surface of the heat exchange tube, and a temperature detecting surface of the temperature detecting device is fitted to the outer surface of the heat exchange tube.

Temperature detecting device and battery pack

A battery box including a lower box body, where the lower box body includes a first plate and a second plate. The first plate includes: a bottom wall; a peripheral wall connected to a periphery of the bottom wall and extending upward; and the bottom wall and the peripheral wall form an accommodating space opening upwards; the second plate is fixed to the bottom wall from a bottom and engages with the bottom wall to form a flow passage. The second plate is provided with: a second protrusion protruding to the first plate from a side facing away from the first plate and extending along a transverse direction; and an opening running through the second protrusion in a height direction and extending along the transverse direction, the second protrusion of the second plate being connected to the bottom wall of the first plate in a sealed manner.

Battery box

The present disclosure provides a battery heat exchange system which comprises a liquid feeding mechanism, a heat exchange mechanism and a liquid draining mechanism. The liquid feeding mechanism provides a circulating liquid. The heat exchange mechanism is connected with the liquid feeding mechanism and comprises a plurality of heat exchange units and a plurality of connecting units; each heat exchange unit is used to heat or cool a corresponding battery module, and the plurality of connecting units are used to connect the heat exchange units together in series-parallel. The liquid draining mechanism is connected with the heat exchange mechanism, and the circulating liquid provided by the liquid feeding mechanism flows through the heat exchange mechanism and then is drained from the liquid draining mechanism.
