# Compact Concept Fuel Cells Battery.Family Composes Larger Power Sources By Combining Smaller Ones By Amelia Roblin | Published 2013-01-18 | Unique Source: Trend Hunter, https://www.trendhunter.com/trends/batteryfamily References: [yankodesign](http://www.yankodesign.com/2013/01/17/the-power-of-a-family-huddle/) With the Battery.Family in mind, think about the implications for [reduced packaging](https://www.trendhunter.com/trends/power-bank-concept) and the frequent shortages people have in the correct fuel cell for the job. This innovative concept proposes a modular system for the portable power source that involves the building of greater batteries from the joining of smaller ones. Perhaps inspired by the Russian nesting doll, Hyojin Park, Junho Yoon, Soohwan Kim and Dohoon Lee began with the AAA as the tiniest unit and integral for the operation of every level above it. It can be sheathed by a series of [hollow cylinders of increasing diameters](https://www.trendhunter.com/trends/household-energy-resilience) that gradually turn it into an AA, a C and a D. The Battery.Family equips you with any strength you might need, as well as the facility to easily borrow between devices requiring different sizes. ## Trend Insights (Trend Hunter) - Score: 2.7/10 - Popularity: 34% | Activity: 39% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Unique](https://www.trendhunter.com/unique) > [Inventions](https://www.trendhunter.com/inventions) ## Key Themes ### What's Driving This Trend - **Modular Power Supplies:** The Battery.Family proposes a modular system for the portable power source that involves the building of greater batteries from the joining of smaller ones. - **Reduced Packaging:** The Battery.Family has the potential for reduced packaging with its modular system for the portable power source that involves the building of greater batteries from the joining of smaller ones. - **Flexible Power Devices:** The Battery.Family equips you with any strength you might need, as well as the facility to easily borrow between devices requiring different sizes. ### Who This Affects Most - **Consumer Electronics:** The Battery.Family's modular system could benefit the consumer electronics industry, offering a flexible power source solution with reduced packaging. - **Green Energy:** The Battery.Family's modular system could have disruptive innovation opportunities for the green energy industry, making fuel cells more accessible and easier to combine for different purposes. - **Automotive:** The Battery.Family's modular system could have disruptive innovation opportunities for the automotive industry, offering a more compact and flexible solution for power sources in vehicles. ## Related on Trend Hunter - [Sustainable Rechargeable Batteries](https://www.trendhunter.com/trends/paleblue-usbc-cells.md) - [Versatile Hydrogen Battery Systems](https://www.trendhunter.com/trends/hydrogen-cartridges.md) - [Modular Solar Power Systems](https://www.trendhunter.com/trends/modular-solar-power-system.md) - [Stackable Module Power Systems](https://www.trendhunter.com/trends/modular-power-system.md) - [Hydrogen Fuel Supplies](https://www.trendhunter.com/trends/portable-hydrogen-cartridge.md) - [Minimal Pebble-Like Battery Packs](https://www.trendhunter.com/trends/battery-pack-2.md) - [Stackable Blocky Chargers](https://www.trendhunter.com/trends/bang-design.md) - [Pouch Cell Battery Designs](https://www.trendhunter.com/trends/cell-battery-design.md) - [Customizable Portable Power Stations](https://www.trendhunter.com/trends/geelink-gl02.md)
