Tools for disassembling wind energy storage batteries

What is a battery pack disassembly?

Robotic disassembly involves several research topics such as Task and Motion Planning (TAMP), robot tool design, and robot sensor-guided motion. Battery pack disassembly is a part of this field of applications as a practical approach to preserving operators’ safety and health by coping with the high variability of products [38, 64].

Can robotics help EV battery disassembly?

This paper analyses the use of robotics for EVs’ battery pack disassembly to enable the extraction of the battery modules preserving their integrity for further reuse or recycling.

How is the battery disassembly controlled by infrared cameras?

The overall disassembly will also be controlled by infrared cameras monitoring the temperature of the battery pack, being able to raise an alert in case of temperature change prediction of a possible thermal runway with the consequent evacuation of the battery cell.

Why is battery discharging important?

The battery discharging is also crucial because the Battery Management System (BMS) prevents over-discharging the cells, so battery packs, even after discharge, will have a residual charge during the disassembly. The high development rate of battery technologies makes it challenging to follow adequate regulations.

Can a robotic cell disassemble a battery pack?

The analysis highlights that a complete automatic disassembly remains difficult, while human-robot collaborative disassembly guarantees high flexibility and productivity. The paper introduces guidelines for designing a robotic cell to disassemble a battery pack with the support of an operator.

How ATEX 3 battery pack was disassembled?

Following the recommendations given after the safety analysis, as a specific potentially explosive atmosphere (ATEX) 3 zone, the battery pack was manually disassembled. The manual disassembly brought to a disassembly procedure which was decomposed and analysed to identify how to automate the same operations with a robot.
