Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a cell temperature detection device for energy storage systems. Background Technology

[0002] With the increasing global demand for clean energy, energy storage systems, as a key technology for balancing energy supply and demand and improving energy efficiency, have been widely used in renewable energy generation, smart grids, and electric vehicles. Energy storage systems can store excess electrical energy and release it when needed, effectively alleviating the time and space mismatch between energy production and consumption. As the core component of an energy storage system, the performance and lifespan of the battery cell directly determine the overall performance of the system.

[0003] Most existing battery cell temperature detection devices use temperature sensors fixed near the battery cell. This method can only detect the temperature at a single location within the battery cell. During charging and discharging, the heating conditions vary in different parts of the battery cell. For example, the heat generation rate and heat dissipation conditions differ in the electrode-electrolyte contact area, the center of the battery cell, and the edges of the battery cell. Detecting only a single point or a few points makes it difficult to know the overall temperature distribution of the battery cell and to detect excessive local heating in a timely manner. Therefore, this utility model proposes a battery cell temperature detection device for energy storage systems. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing cell temperature detection technologies only detect a single location and cannot accurately determine the overall temperature distribution of the cell, and to propose a cell temperature detection device for energy storage systems.

[0005] The technical solution of this utility model is as follows: A cell temperature detection device for an energy storage system, comprising a bracket, and further comprising:

[0006] The track plate is fixedly mounted on the bracket, and a placement plate is fixedly mounted on the bottom of the track plate. The placement plate is hollow, and the bracket is equipped with a detection device for omnidirectional detection of the temperature of the battery cells on the placement plate.

[0007] Furthermore, the detection device includes a slider slidably mounted on a track plate, a connecting block fixedly mounted on the bottom of the slider, an electric turntable fixedly mounted on the connecting block, a connecting rod fixedly mounted on one side of the electric turntable, an mounting ring fixedly mounted on one side of the connecting rod, multiple temperature sensors arranged at equal intervals fixedly mounted on the inner wall of the mounting ring, a placement plate passing through the mounting ring, a reciprocating screw rotatably mounted inside the track plate, the reciprocating screw being threadedly connected to the slider, a motor fixedly mounted on one side of the track plate, the output shaft of the motor being fixedly connected to the reciprocating screw, and a cleaning mechanism for dust removal from the surface of the temperature sensors provided on the bracket.

[0008] Furthermore, the cleaning mechanism includes a blower fixedly mounted on a bracket, connecting pipes fixedly mounted on both sides of the blower, an installation cavity opened in the placement plate, a plurality of nozzles arranged at equal intervals fixedly mounted in the installation cavity, one end of the connecting pipe communicating with the placement plate, a telescopic plate slidably mounted on the placement plate, the telescopic plate covering the nozzles, a handle fixedly mounted on the telescopic plate, and the handle having anti-slip texture.

[0009] Furthermore, a groove is provided on the track plate, and a protrusion is fixedly installed on the slider, with the protrusion slidably connected to the groove.

[0010] Furthermore, a support column is fixedly installed on the bracket, and the support column is fixedly connected to the track plate.

[0011] Furthermore, a display screen is fixedly installed on one side of the support column, and the output terminal of the temperature sensor is electrically connected to the input terminal of the display screen.

[0012] Furthermore, a plurality of equidistantly arranged circumferential fixing blocks are fixedly installed on the inner wall of the mounting ring, and one end of each fixing block is fixedly connected to a temperature sensor.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] This invention uses a motor to drive a reciprocating lead screw to rotate, which in turn drives an electric turntable to rotate a mounting ring. This allows the temperature sensor on the mounting ring to both reciprocate horizontally and rotate, enabling the temperature sensor to surround the battery cell and achieve multi-directional temperature detection, thus improving detection accuracy.

[0015] This invention uses a blower to deliver air through a connecting pipe into the placement plate. By pulling open the telescopic plate and exposing the nozzle, air is sprayed out from the nozzle. In conjunction with the starter motor and electric turntable, the sprayed gas can remove dust from the surface of the temperature sensor, preventing dust from affecting the accuracy of the detection.

[0016] This invention enables multi-directional detection of battery cell temperature, improves the accuracy of detection results, facilitates maintenance, and is highly practical. Attached Figure Description
