Problems solved by technology

When the temperature sensor is bonded to the thermal silica gel, there are problems that the bonding position cannot be consistent, the bonding operation is difficult, and it cannot be replaced quickly
The temperature sensor is also fixed by screws, but it takes a lot of time to fix the screws, resulting in lower production efficiency and higher cost
In addition, the temperature sensor is fixed by welding, but the operation and replacement of the welding process is inconvenient, and the welding quality is difficult to guarantee

Abstract

The invention discloses a power battery temperature detection structure, which comprises a body and a temperature sensor. The body comprises a thermal conductive silica gel block and a common silica gel block. The temperature sensor is vertically arranged between the thermal conductive silica gel block and the common silica gel block. The bottom of the body is provided with a guiding localization body. The guiding localization body comprises a locating block which is fixed with the body, a guide block capable of moving inwards from the lateral side of the locating block, and an elastic component for pushing the guide block far away from the locating block. Inside the body is a cavity. A piston for adjusting volume of the cavity is arranged inside the guiding localization body. An action block, which drives the piston to move far away from the cavity when the guide block is approaching to the locating block, is arranged inside the guiding localization body. The invention aims to provide the power battery temperature detection structure which is convenient for installation and replacement.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a power battery temperature detection structure. Background technique [0002] Power battery is one of the core components of electric vehicles and the power source of the whole vehicle. The power battery is generally composed of battery cells to form a module, and then the module is assembled into a battery pack. When the entire battery pack is charged and discharged, its working efficiency, service life and safety performance are all affected by temperature, and the temperature must be controlled reasonably. This temperature includes the effects of ambient temperature and battery self-heating. The car battery pack is composed of multiple lithium-ion batteries connected in series and parallel, maintaining the consistency of the temperature of each battery is also one of the important indicators of the car battery pack. It can be seen that the thermal management design of the...
