AI Technical Summary

Technical Problem

The existing battery module aging detection device has a fixed cabinet volume, which leads to wasted space and energy when testing a small number of battery modules, and cannot be flexibly adjusted.

Method used

Design an expandable testing chamber. The volume of the internal cavity of the chamber is adjusted by sliding the expansion chamber driven by an electric cylinder. Combined with salt spray duct, steam duct and hot air blower to simulate different environments, bracket and testing tray ensure uniform gas contact, and stepper motor drives the tray to rotate to enhance the contact effect.

Benefits of technology

It enables flexible adjustment of the detection space based on the number of battery components, reducing energy waste, and can simultaneously simulate multiple environments to ensure uniform contact between battery components and gas, thereby improving detection efficiency and accuracy.

Abstract

This invention provides a battery module aging detection device, relating to the field of battery testing technology, comprising: a detection chamber; an extension chamber slidably mounted on the outside of the detection chamber, a first door rotatably mounted on the front of the detection chamber, and a second door rotatably mounted on the front of the extension chamber; salt spray conduits and steam conduits extending into the interior are provided on both sides of the detection chamber, and nozzles are provided at one end of the salt spray conduits and steam conduits inside the detection chamber; a bracket is fixed inside the detection chamber, and a detection tray is rotatably mounted on the inner side of the bracket; a hot air blower is installed in the cavity inside the bottom of the detection chamber; a stepper motor is installed in the motor cover, and a rotating shaft is connected to the top of the stepper motor's main shaft, with gears installed on the outer side of the rotating shaft. This device can adjust the volume of the cavity inside the chamber, thereby allowing for targeted adjustments based on the number of battery modules to be tested, improving adaptability and reducing energy waste.
