Graphene battery charges in just five minutes

The Independent

Billions of pounds have been poured into research of the "revolutionary" material graphene, though few real-world applications have so far been realised. A Catalan startup called Earthdas is aiming to address that by producing a graphene-based battery that it claims can charge 12-times faster than current lithium-ion batteries – potentially transforming the usability of electric vehicles by decreasing charging times from hours to just five minutes. "Currently, cities are experiencing an obvious shift in terms of mobility," Rafa Terradas, founder of Earhdas, told ZDNet. "We're all aware we must reduce the space occupied by combustion vehicles and incorporate innovative solutions to reduce pollution. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.

Almost two years ago, Rafa Terradas was thinking about developing an innovative bicycle, unlike anything else on the market. At the time, he was also collaborating with the Spanish National Research Council, CSIC, on a project using artificial intelligence and robotics to help autistic children communicate with their environment. There, he met members of the research group from the Catalan Institute of Nanoscience and Nanotechnology (ICN2) dedicated to graphene, which is a super-thin material that's stronger than steel, more conductive than copper, and flexible.


What Automotive Companies Are Showing At CES Asia: Electric, Hydrogen, And Autonomy, Of Course

Forbes Technology

Wandering the halls of CES Asia it's easy to spot the automotive companies, but sometimes you have to look at the logos instead of looking for actual vehicles on display. The booths here at the show in Shanghai, China are full of global and domestic brands showing off everything from self-driving vehicles to futuristic concepts to useful doo-dads for today's cars. The focus of the automakers here at @CESAsia is obviously not on the cars themselves, but on mobility. You hear this a lot, but to see the @Honda booth with no actual cars in it really drives that home. Just because Honda didn't have any actual vehicles on display is not to say that every company wanted to promote mobility ideas over cars.


China's ambition to power the world's electric cars took a huge leap forward this week

MIT Technology Review

China's grand designs to dominate the future of clean energy paid off spectacularly this week. In a public offering on June 11 in Shenzhen, battery giant Contemporary Amperex Technology Ltd. (CATL) raised nearly $1 billion to fund ambitious expansion plans, and its stock has been shooting up every day since. Thanks largely to the company's new plants, China will be making 70 percent of the world's electric-vehicle batteries by 2021, according to Bloomberg New Energy Finance (BNEF). The rapid rise of CATL is arguably the clearest, though certainly not the only, payoff from China's calculated efforts to bolster its domestic battery and electric-vehicle industries--two of the most promising sectors in clean energy. These efforts have largely followed the same playbook China used to get ahead in solar panels, including highly automated manufacturing; aggressive efforts to lock in global supply chains; foreign acquisitions and licensing; and hefty doses of government support and protectionism.


New battery technology is accelerating autonomy and saving the environment

If the robotics world had a celebrity it would be Spot Mini of Boston Dynamics. Last month at the Robotics Summit in Boston the mechanical dog strutted onto the floor of the Westin Hotel trailed by hundreds of flickering iPhones. Marc Raibert first unveiled his metal menaagerie almost a decade ago with a video of Big Dog. Today, Mini is the fulfillment of his mission in a sleeker, smarter, and environmentally friendlier robo-canine package than its gas-burning ancestor. Since the early 1990s, machines have relied on rechargeable lithium ion batteries for power.


A Study of EV BMS Cyber Security Based on Neural Network SOC Prediction

arXiv.org Machine Learning

Recent changes to greenhouse gas emission policies are catalyzing the electric vehicle (EV) market making it readily accessible to consumers. While there are challenges that arise with dense deployment of EVs, one of the major future concerns is cyber security threat. In this paper, cyber security threats in the form of tampering with EV battery's State of Charge (SOC) was explored. A Back Propagation (BP) Neural Network (NN) was trained and tested based on experimental data to estimate SOC of battery under normal operation and cyber-attack scenarios. NeuralWare software was used to run scenarios. Different statistic metrics of the predicted values were compared against the actual values of the specific battery tested to measure the stability and accuracy of the proposed BP network under different operating conditions. The results showed that BP NN was able to capture and detect the false entries due to a cyber-attack on its network.


Musk promises manufacturing, self-driving, battery breakthroughs--and profits – Ars Technica

On Tuesday, Tesla held its annual shareholder meeting. As expected, none of the controversial shareholder votes passed--there will be no independent CEO replacing Musk, and his brother and the other two candidates were reelected to the board with no drama or fireworks. Even Tesla's chief counsel Todd Maron referred to the opening agenda items as "the boring bits." Things got more interesting once Musk took to the stage for a Q&A session, answering queries submitted in advance via Twitter and then from the audience. It was an odd performance, often feeling more like a Netflix comedy special than a shareholder meeting.


The Race to Send Robots to Mine the Ocean Floor

WIRED

When the 300-foot Maersk Launcher docked in San Diego early Monday morning, it unloaded a cargo of hardened black blobs scooped from the bottom of the sea. The blobs are not rocks, but naturally-occurring metallic nodules that could one day yield metal deposits of cobalt, manganese, and nickel--not to mention scarce rare earth minerals. As worldwide demand rises for electric vehicle batteries and wind turbines, along with next generation technologies and weapon systems, demand for these metals has taken off. And the seabed is a prime target for those mining operations. Of course, it's no small feat to bring these potato-sized nodules from the bottom of the remote Pacific Ocean, and then sail them to a processing plant where the metals can be extracted.


Google I/O: Google Plans To Embed DeepMind's Machine Learning Software Into Android

Forbes Technology

LONDON, ENGLAND - DECEMBER 05: Co-founder of Google DeepMind Mustafa Suleyman attends a Q&A during day 1 of TechCrunch Disrupt London at the Copper Box on December 5, 2016 in London, England. Google has found another use for DeepMind's machine learning software after buying the London artificial intelligence lab for a reported £400 million in 2014. Later this year, the search giant will roll out two new DeepMind-built Android features that are designed to improve battery life and optimise screen brightness levels. The features will be available to people with devices running the Android P operating system. The features -- announced during the Google I/O developer conference -- were built by a unit called "DeepMind for Google," which focuses on applying DeepMind's technology to Google products.
