2nd life energy storage: redesign, reuse and recycling of electronic waste
2023 master thesis
Cooperation: ENGIE Energy Access
A substantial amount of electronic waste accumulates each year within the company.
Battery packs have battery-management-systems that protect them from overvoltage, undervoltage, overcurrent and for cell balancing
Battery-management-systems protect battery packs
BMSs protect battery packs
Bigger battery packs need bigger and more powerful battery-management-systems
What if not? Can we repurpose smaller ones?
Make many small BMSs work as one big one in order to save resources and costs.
repurposed & recycled
repurposed
new parts
Fully disassemblable modules made out of standard components. Electrical contact through compression. No cell spot-welding.
A prototype was built and tested at ENGIE Energy Access in Zambia.
