Testing Hundreds of Used LFP Cells Requires Some Automation
A project aimed at repurposing hundreds of used lithium iron phosphate (LFP) battery cells for a go-kart required an automated testing system due to the large number of cells involved. The team developed a custom battery tester called Cell Goblin, which uses an ESP32-S2 microcontroller and software to efficiently charge, discharge, and measure each cell. This automation significantly reduced the time and effort needed to assess the condition of each cell, making the process more practical and scalable. The system is now available on GitHub for others to use or improve.
A project to test 768 used lithium iron phosphate (LFP) battery cells required automation due to the large number of cells involved.
Automating the testing process improves efficiency and accuracy when evaluating large batches of used battery cells for reuse.
This story highlights a practical, hands-on solution to a real-world problem, showing how innovation can make sustainable projects more feasible.
