点击翻译按钮获取中文摘要

*Issue – Worldwide 1.2bn people lack access to the electricity grid. With IUK support, BuffaloGrid (BG) hasdeveloped a solar powered Hub providing PAYG electricity, off grid mobile phone charging and wirelessinternet in developing regions. BG hubs currently contains Li-ion cells spot welded together in caddies.However, battery packs connecting multiple cells without a Battery Monitoring System have veryrestrictive export/import requirements. Cell welding is also an expensive process, prevents reuse ofbattery packs extracted from EoL BuffaloGrid Hubs in other devices and prevents use of upcycled Li-ionbatteries.*Solution - In this VOLT feasibility project , BuffaloGrid will investigate the feasibility of developing abattery pack that uses compression to hold Li-ion cells together and develop a prototype.*Challenges for BuffaloGrid - Due to the harsh operating environment of BuffaloGrid Hubs, developing aCaddy that uses compression is challenging.
