Member company CE+T Power wins Google ‘Little Box Challenge’

In September last year we reported that CE+T Power was one of the finalists of the 'Little Box Challenge', a competition organised by Google and the IEEE (Institute of Electrical and Electronics Engineers). We are proud to announce that this business from Liege has also actually won the contest with the small inverter called ‘Effy’, the result of a successful cooperation with several players including Sirris.

The Little Box Challenge was launched in 2014 as a joint initiative of Google and IEEE in their search for new technology to successfully shrink an inverter to the size of a small laptop. The innovative solution of CE+T Power is a huge improvement compared to the original specification of the competition, which indicated 50 W per cubic inch. The winning design does not only boast 145 W per cubic inch (8.848 W/litre), but also measures only 13.77 cubic inch (0.225 l), which is smaller than a stack of post-it blocks and, therefore, much smaller than originally requested. This was achieved only by using technology which was already available on the market.

Boost for further innovation

Winning the Little Box Challenge presents the SME with a unique head-start to address the crucial improvements required in power storage. The company aims to apply some critical and necessary design alterations and, through this innovation, change the future of electricity, power and even Smart Home technology. This is how it intends to find a solution for the power storage in critical professional applications. Power is currently stored as direct current, while it is produced, transported and used in the form of alternating current. Converting the direct current into alternating current requires the use of an inverter, and that is why changing the dimensions was a priority.

The CE+T Power design was selected as the winner among 18 other finalists and from hundreds of entries from across the globe. The awarded development is the result of the ‘Red Electrical Devils’ team, a cooperation between industrial partners, universities, study centres and with the support of the Walloon region. Sirris also made contributions to thermal simulation and the miniaturisation of the cooling system. 

CE+T Power took home no less than USD 1 million.
