[0082] Example 2

[0083] like Figure 4 As shown, this embodiment provides a method for constructing a battery disassembly information database, based on the power battery auxiliary disassembly test device described in Embodiment 1, including the following steps:

[0084] Step 1: Simulate various environmental conditions of the battery based on the configured environmental parameters;

[0090] The specific implementation process of this embodiment is the same as that of Embodiment 1. See Embodiment 1 for details. The detection unit simulates various battery operating environments, including different temperature states, humidity states, vibration intensities, and electromagnetic compatibility. It detects the battery's charging and discharging power, maximum charging power and duration, and maximum battery capacity under these conditions, and transmits this information to the controller. For example... Figure 5The system displays the charging power curves of the battery at different temperatures to demonstrate its performance changes under various operating conditions. A battery fixing device secures the battery and drives its rotation and lifting. A component rotation auxiliary device, a connection breaking auxiliary device, and a cell flipping auxiliary device are used to achieve the rotation of the components to be disassembled, connection breaking, and cell flipping. Sensors mounted on the auxiliary devices simultaneously acquire the component disassembly time and energy consumption. A mechanical clamping device transports the disassembled components via a guide rail to a component scanning device. After obtaining a 3D model, the components are collected and stored by a component collection device. Based on the charging and discharging power, maximum charging power and holding time, maximum battery capacity, component disassembly time and energy consumption acquired during the disassembly process, and the 3D models of the components obtained under different environments, a battery disassembly information database is constructed.

[0091] Finally, a three-dimensional model of the parts was acquired using a scanning device installed in the disassembly experimental chamber. Based on battery performance obtained under various environments, disassembly time and energy consumption during the disassembly process, the disassembly mechanical auxiliary devices used, battery temperature, and the content of released gases, a complete battery disassembly information database was constructed through a controller and data processing platform. This database provides rich information support for subsequent research on the constraints of disassembled parts and the planning of disassembly sequences. For example... Figure 6 The diagram illustrates the content of harmful gases generated during the disassembly of each component in the battery disassembly process.
