A UK company, Extreme Low Energy (ELe), has produced a new battery system which can power a suite of computers for almost eight years.
Tests conducted over a five-month period by engineers at The University of Manchester showed that Extreme Low Energy (ELe)'s POD could power 30 computers for seven hours a day over 2,830 consecutive days (7.75 years) before the battery capacity dropped to 80%.
The pioneering low energy system "“ which can also act as a back-up generator "“ is attracting interest from schools in developing African nations.
The POD stores energy in high-performance lithium-ion batteries, charging overnight to make use of off-peak energy tariffs before supplying power to ELe's suite of low energy PCs and monitors.
When used in conjunction with a low-energy computing suite, ELe claims its POD can help organisations save at least 70% in energy costs.
Dr Rebecca Todd, School of Electrical and Electronic Engineering at The University of Manchester, said:
"We applied our findings specifically to consider the use of the ELe POD in educational establishments, and concluded that an average school should be able to use the POD system for over 14 years before the battery reaches 80% capacity."
Mark Buchanan, founder of Extreme Low Energy, said:
"As a specialist in the manufacturing of energy storage technologies and alternative energy generation devices the POD is just one innovative product we offer to help customers operate partially or fully off-grid.
"We were confident about the longevity of our POD before the testing - but the findings certainly impressed us.
"We're sure that the results of these independent tests will help prove the value of our DC-power solutions and technologies to potential customers both in the UK and overseas."
AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST)
and will feature online
versions of the market-leading physical events: CS International
and PIC International
PLUS a brand new Silicon Semiconductor International
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
