Description

Technical Field

[0001] Cross - reference to Related Applications This application claims the benefit of Chinese Patent Application No. CN202411997278.0, filed with the China National Intellectual Property Administration on December 31, 2024, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to the field of charging technologies for electric vehicles, and particularly to a charging dock provided with a temperature detection module and a temperature detection module.

Background Art

[0003] In the prior art, in order to charge the battery pack of a new - energy electric vehicle, it is necessary to install a charging dock suitable for fitting into the charging gun of the new - energy electric vehicle. To improve the charging speed, it is necessary to increase the charging current. Currently, the charging current is as high as 600 A and may further increase to 1000 A in the future. When a large current flows through the power terminals in the charging dock, a large amount of heat is generated, and the temperature of the power terminals in the charging dock may rise rapidly. If the temperature rise cannot be controlled in a timely manner, there is a risk of safety accidents such as burning of the charging dock or other electrical equipment.

[0004] In the prior art, in order to control the temperature rise of the power terminals, usually, a lead frame is mounted on the charging dock, and a temperature detection module is incorporated into the lead frame. The temperature detection module includes a temperature sensor and a heat pad wound around the outside of the temperature sensor. The heat pad is in thermal contact with the power terminals, and the temperature sensor is electrically connected to the lead frame. However, in the prior art, the lead frame is large in volume and needs to be pre - mounted on the charging dock housing, which is very inconvenient to use. In addition, in conventional technology, the charging dock housing must adopt a split design to facilitate the attachment of the lead frame, which complicates the structure of the charging dock housing. Furthermore, existing lead frames must be rotatable between a locked position that locks the power terminals and an unlocked position that unlocks the power terminals, which makes the lead frame and charging dock housing more complex, more difficult to assemble, and more expensive.
