    Accelerating battery charging speed, Stanford research uses AI as magic key.

    2020-04-14
    The key to the popularity of electric vehicles lies in whether the charging speed of batteries can be improved, which can gradually make charging as convenient as fuel charging. Both battery and electric vehicle manufacturers are committed to the research and development of fast-charging technology. A team from Stanford University, Massachusetts Institute of Technology and Toyota Research Institute published a new study in Nature, revealed how artificial intelligence could speed up the testing process required for novel charging techniques. The problem of battery fast charging is that under the condition of fast charging, the degradation rate of battery will be accelerated, and even the risk of overheating and fire. However, to evaluate the impact of different charging methods on the battery, hundreds of charging and discharging cycles must be carried out until the battery fails to test the battery life. Every new battery composition or every new charging method can only make out the results after such a long charge discharge cycle, and then it can be improved by waiting for hundreds of charging and discharging cycles to see how the new results are. It is conceivable that the speed of R & D is bound to be greatly encumberd. The research team applied artificial intelligence to solve the problem of time-consuming experiment. The research started in 2017 when Toyota Research Institute invested 35 million US dollars for research on artificial intelligence auxiliary battery, the original goal is to develop new battery materials. In 2019, the research team changed to use artificial intelligence to assist the computer to simulate the battery charging and discharging cycles. It only needs 9% of the actual charging and discharging test time, so it can evaluate 224 possible high-cycle-life charging processes in just over two weeks. Undoubtedly, this will greatly increase the research and development speed of fast charging. With the development of battery technology and charging technology, the service life is getting longer and longer. The time from charging and discharging cycle to the end of service life will be longer and longer. Computer simulation will be a compromise solution. First, find out the best possible technology through computer simulation, and then conduct field test, which can greatly reduce the time of trial error. Artificial intelligence is not only applied in the research stage, but also in the Canadian new business, GBatteries, uses artificial intelligence directly to accelerate the charging speed. When fast-charging, artificial intelligence can evaluate the battery condition at any time. Once it may cause battery damage, suspend charging to avoid irreversible damage to the battery. It can avoid damaging the battery and charge at the fastest possible speed. GBatteries technology is currently only applied to small batteries. When it is used in electric tools, the charging time can be reduced from 30-60 minutes to 11 minutes. However...

  • Digital Instrument Cluster Design Solution

    Digital Instrument Cluster Design Solution

    2020-04-09
    The virtual automobile cluster replaces the most representative parts of the existing cluster such as indicators and digits with a screen. Its advantage is that users can define their own instrument system to meet different requirements, which is more powerful, flexible and easier to connect with the network, peripherals and other applications. Virtual automobile instrument cluster benefits from more powerful graphics processing and display effect, more indicators are designed by quasi-physical method, which can effectively shorten the user's acceptance process. Multimedia entertainment information and basic vehicle information can also be displayed more logically, centralized display helps to improve driving safety, and driving sight does not need to switch frequently in multiple locations; in addition, simplicity The design can also leave more space for the ride area or storage. Although LCD technology is mature now, it is not only simple to install a LCD cluster on a car with a display screen. In fact, this is rather complex system engineering. After changing to LCD screen, first of all, the vehicle information presented to drivers is much richer than the traditional instrument cluster. The collection of information, the cooperation of LCD cluster and sensor, the precision adjustment of display instrument and so on, all need to be overcome one by one by the car manufacturers. And each vehicle must undergo strict high and low temperature test before mass production; as part of the whole vehicle, the instrument panel module should also meet the same high and low temperature test standards. But because the space in the dashboard bin is relatively small, and the GPU of the LCD module, the display screen and so on will heat up in the use process. The higher resolution of LCD screen, the higher the calorific value. Therefore, finding or developing a suitable hardware product for vehicle interior environment and matching a set of hardware environment to meet the requirements of vehicle use are also technical difficulty that the R&D team has to overcome. With 40 years of design experiences by implementing NXP solutions, FIC products coupled with rising digitization that leads to everything seamless connected. We offer wide range of edge computing cuts across the IoT, from S.M.B, building automation and to the most complex vehicle with variety of NXP solutions in order to design and produce automotive digital cluster for your special needs.

  • Coronavirus May Mean Automation Is Coming Sooner Than We Thought

    Coronavirus May Mean Automation Is Coming Sooner Than We Thought

    2020-03-23
    We’re in the midst of a public health emergency, and life as we know it has ground to a halt. The places we usually go are closed, the events we were looking forward to are canceled, and some of us have lost our jobs or fear losing them soon. But although it may not seem like it, there are some silver linings; this crisis is bringing out the worst in some (I’m looking at you, toilet paper hoarders), but the best in many. Italians on lockdown are singing together, Spaniards on lockdown are exercising together, this entrepreneur made a DIY ventilator and put it on YouTube, and volunteers in Italy 3D printed medical valves for virus treatment at a fraction of their usual cost. Indeed, if you want to feel like there’s still hope for humanity instead of feeling like we’re about to snowball into terribleness as a species, just look at these examples—and I’m sure there are many more out there. There’s plenty of hope and opportunity to be found in this crisis. Peter Xing, a keynote speaker and writer on emerging technologies and associate director in technology and growth initiatives at KPMG, would agree. Xing believes the coronavirus epidemic is presenting us with ample opportunities for increased automation and remote delivery of goods and services. “The upside right now is the burgeoning platform of the digital transformation ecosystem,” he said. In a thought-provoking talk at Singularity University’s COVID-19 virtual summit this week, Xing explained how the outbreak is accelerating our transition to a highly-automated society—and painted a picture of what the future may look like. Confronting Scarcity You’ve probably seen them by now—the barren shelves at your local grocery store. Whether you were in the paper goods aisle, the frozen food section, or the fresh produce area, it was clear something was amiss; the shelves were empty. One of the most inexplicable items people have been panic-bulk-buying is toilet paper. Xing described this toilet paper scarcity as a prisoner’s dilemma, pointing out that we have a scarcity problem right now in terms of our mindset, not in terms of actual supply shortages. “It’s a prisoner’s dilemma in that we’re all prisoners in our homes right now, and we can either hoard or not hoard, and the outcomes depend on how we collaborate with each other,” he said. “But it’s not a zero-sum game.” Xing referenced a CNN article about why toilet paper, of all things, is one of the items people have been panic-buying most (I, too, have been utterly baffled by this phenomenon). But maybe there’d be less panic if we knew more about the production methods and supply chain involved in manufacturing toilet paper. It turns out it’s a highly automated process (you can learn more about it in this documentary by National Geographic) and requires very few people (though it does require about 27,000 trees a day—so stop bulk-buying it! Just stop!). The supply chain limitation here is in the raw material; we certainly can’t keep cutting down thi...

  • AR/VR/XR – Farewell to exaggeration, Get More Substance

    AR/VR/XR – Farewell to exaggeration, Get More Substance

    2020-03-17
    ‘’AR and VR and other real-world interactive technologies gradually get rid of hype and become more practical. In fact, AR / VR / XR and other technologies have found a more suitable place in the market for their technology applications.’’ From this year’s CES 2020, augmented reality (AR) and virtual reality (VR) and other real-world interactive technologies are no longer as hyped as CES in previous years, but gradually become more practical. In fact, from safe driving, manufacturing site, consumer games to professional fields, AR/VR/XR has found more in line with the technology’s position in the marketplace. Althought CES has come to the end, we can still find the application of AR/VR/XR. For example, there were number of booths that used VR for demonstration purposes, especially the automobile manufacturers. Honda, Jeep and Audi demonstrated that used VR to simulate driving conditions. The Jeep 4×4 Adventure VR Experience was a simulated off-road journey on the famous off-road trail called Moab’s “Hell’s Revenge.” Each wheel of the Jeep Wrangler Rubicon is equipped with hydraulic cylinder, so that jeeps can respond to the location of the wheels on the driveway. The hydraulic system replicates the movement and sight that the driver experiences during the off-road journey when wearing VR glasses, making it seem to be in the resort of Moab off-road. In addition to taking off-road experience as the selling point of today's vehicles, Future Honda Mobility lets us preview the future action ecosystem using VR, which may be the actual situation in 2035 and beyond. Honda provides the future urban environment experience with V2X system, including safe driving, Autonomous Shared Mobility Pod, and take flight in a personal vertical takeoff and landing (VTOL) vehicle. CES 2020 did not release any new AR / VR products, most of which were released in 2019; however, that hadn’t been the case in the past. This year's more breakthrough product is Nreal AR glasses. Nreal initially launched its developer edition product at Augmented World Expo (AWE) in 2019 and has been showing ever improved versions since. The company continues to work closely with Qualcomm to develop lightweight AR glasses for use with Snapdragon processor enabled mobile phones, or stand-alone computer devices using the Qualcomm Snapdragon 845 processor. I have tried the glasses and have seen that the overlay image is quite bright and has a wide field of view. The glasses support six degrees of freedom (6-DoF) movement. This year, the Nreal light AR glasses finally came out of the consumer version, which tether to a Snapdragon-based phone. New user interface, Nebula UI, also helps bring 2D applications (APPs) into the 3D world, allowing users to launch 2D apps and place them anywhere in the 3D space. Oculus Quest now is the most popular VR headwear device, that was out of stock for weeks around the holidays. I order one on December 13, and finally got my product after CES. Oculus Quest head...

  • SpaceX upgrades the automatic recovery ship and installs a new rocket recovery robot

    SpaceX upgrades the automatic recovery ship and installs a new rocket recovery robot

    2020-03-10
    According to Teslarati, Space Exploration Technologies Corp (SpaceX) has kicked off a series of major upgrades planned for its East Coast Autonomous spaceport drone ship, and launched a new second tank-like rocket recovery robot. SpaceX named the rocket recovery robot ‘’Octagrabber’’. Since 2017, SpaceX has been using rocket recovery robot on drone ship OCISLY. While far from autonomous, Octagrabber helps SpaceX’s maritime rocket recovery team minimize the risks workers are subjected to and gives the company a bit more flexibility to attempt Falcon booster landings in less-than-pristine ocean weather. Although the Falcon boosters are relatively stable after landing, most of the air quality is concentrated around nine Merlin 1D engines, and even moderate waves can cause them to slip and slide around the drone ship deck. Aside from the discovery of a second Octagrabber being built at SpaceX’s former East Coast Starship factory, the nature of other upgrades planned for drone ship JRTI are more mysterious. For several months, the rocket landing platform has had almost a dozen massive generators and new thruster pods stored on its deck, seemingly waiting on an unknown impetus for their installation. In recent weeks, visible work to prepare the new hardware for installation has begun. Notably, the thrusters and power supplies installed in JRTI will be dramatically upgraded, which may allow the automatic ship to have higher power than the tug boat. In other words, SpaceX may try to make the automatic drone ship JRTI completely independent of the tug boat, potentially simplifying and lowering the cost of booster recoveries. While less likely, SpaceX will finally be able to fully automate the drone ships, with high-powered thrusters potentially giving JRTI the ability to leave port, cruise to Atlantic Ocean landing zones, deploy Octagrabber, and return to port with a booster that all without humans. This capability may not be realized in recent but powerful thrusters and generators would bring port-to-port drone ship autonomy within SpaceX’s grasp in the near future. News source: technews

  • Possible new 'mini moon' discovered orbiting Earth. It started to circle the earth three years ago

    Possible new 'mini moon' discovered orbiting Earth. It started to circle the earth three years ago

    2020-03-02
    In the earth's orbit, which is full of satellites and human-made debris and only one confirmed natural object: the moon. Recently, astronomers announced that there is a ‘mini moon’ in earth orbit that has been around the earth for three years, named 2020 CD3. The moon is the only natural satellite that has been steadily following the earth since ancient times. In fact, the earth's gravity often accidentally catches other passing small bodies in the solar system. The latter will be temporarily bound in the earth's orbit, and then walk around for a while before leaving again. In September 2006, scientists discovered that the 2006 RH120, a near Earth Asteroid, entered the temporary satellite capture (TSC) and returned to orbit around the sun in June 2007 after circling the earth for several times. In recent days, International Astronomical Union’s Minor Planet Center (MPC) announced that there is a new temporary satellite capture object on earth. It was discovered by Catalina Sky Survey (CSS) that it was captured by earth gravity three years ago, named 2020 CD3 (C26FED2). The object is very small. The estimated diameter of the sunlight reflected from it is only 1.9-3.5 meters. It may leave the earth's orbit sometime in April this year and return to the normal orbit around the sun. If more observations later confirm this, it will be the second known Mini moon among nearly a million known asteroids. But scientists say further analysis is needed to determine whether the object is a space rock, rather than a large piece of space junk made by humans. We hope we can get the answer by April. ——Source:technews

  • McAfee researchers modify the sign of speed limit to easily trick Tesla's Autonomous Driving car from 35mph to 85mph

    McAfee researchers modify the sign of speed limit to easily trick Tesla's Autonomous Driving car from 35mph to 85mph

    2020-02-20
    Researchers stuck a piece of electrical insulating tape on the speed limit sign, which successfully cheated Tesla's electric vehicle to accelerate. It reveals various potential loopholes in the current autonomous driving systems. According to McAfee's research report, technicians pasted tape across the middle of the number of "3" on the speed limit sign of "35" mph, which led to the misjudgment of the speed limit of "85" mph, and then the vehicle's cruise control system accelerated automatically. McAfee said that the problem was not a serious risk for motorist, no one was injured during the experiment, and the researchers who drove the car slowed down safely. But during 18 months research last year, the results shows that autonomous machine learning systems have weaknesses. According to Steve Povolny, director of McAfee's Advanced Threat Research lab, other studies have also shown how changes in the physical world can easily confuse systems. McAfee said: such tests are not common in the real world These tests include the 2016 models s and X, which are using camera systems from Mobileye (now an Intel business unit). Although Tesla stopped using the Mobileye system in 2016, several automakers continued to use it. Mobileye's latest camera system test did not show same fault, and Tesla's latest model no longer relies on only identifying traffic signs, McAfee said. Tesla did not respond to any comment on this study. "Manufacturers and suppliers have been informed of this problem and have further understood and improved it, " Povolny said. "But this does not change the fact that there are many blind spots in the autonomous driving industry. To be sure, the threat to the real world is limited. First of all, autonomous driving is still in the developed stage,most will be tested when the driver can take over the steering wheel safely any time. Although many vehicles support ADAS now, they still need to pay attention to the road conditions. McAfee researchers can only cheat the system by copying a series of specific events, including turning on driving AIDS and encountering tampered speed limit signs. Manufacturers also integrate mapping technology into systems that respond to appropriate speed limits. "Until we have a real autonomous driving car, it is unlikely to see the above situation in the real world, or the attacker tries to exploit these loopholes. At that time, we hope that such defects can be solved as soon as possible. "Povolny said. Even driving can be fooled by such changes; the system that researchers tested was originally designed to aid driving, not to support autonomous driving, Mobileye said. In addition to sensing, autonomous driving needs to improve safety and fault tolerance through various technologies "Autonomous driving technology not only relies on sensing, but also receives various other technologies and data support, such as crowd sourced mapping. It’s for ensure the reliability of received information from camera sensors and pro...

  • China wants to make swappable electric vehicle batteries mainstream

    China wants to make swappable electric vehicle batteries mainstream

    2020-02-19
    Driving an electric car is, for the most part, exactly like driving an internal combustion engine vehicle, except when it comes to refueling. Charging an electric car can often take hours at a time, but China is making a push to support technology that could cut that down to just minutes. According to a Bloomberg report, which cites sources close to the matter, the Chinese government is pushing for common industry standards on battery swapping technology. The standards would allow EV drivers to change the depleted batteries in their cars for fully charged ones, rather than having to charge from an electricity source. China appears to be pushing the battery swapping technology in an attempt to further promote electric vehicles in the country. It’s already the biggest market for EVs in the world. One of the biggest hindrances with owning an EV is the time it takes to charge its batteries. An on-the-go battery swapping system would create a big opportunity for infrastructure not too dissimilar from conventional filling stations. In principle, EV drivers would be able to go to a battery swap station, have their old flat batteries removed, and new fully charged ones put in. The process could take minutes; no longer than it would take to fill a fuel tank. Another potential plus point is that electric vehicles could be sold without batteries, making them cheaper. Batteries would then be leased or bought on a separate plan based on the individual needs of the buyer, making them cost effective. A big ask of electric car makers It sounds great, but it’s not going to be easy. A number of companies have tried over the years, but none have succeeded in consumer markets yet. One startup called Better Place trialed its battery swap technology in Tel Aviv, Israel between 2007 and 2013, and only managed to sell 500 cars. It went defunct after losing over $800 million. Manufacturers just didn’t buy into Better Place’s vision. French marque Renault was the only automaker to give it a shot, and at that it made only one vehicle compatible with Better Place’s tech. Chinese car maker BAIC BluePark New Energy Technology Co. reportedly already has 187 battery-swap stations across 15 cities in China. But those are used solely to support 16,000 electric taxis. Given the size of the Chinese EV market and having government support, its car industry might be able to make progress where others have failed. But the same can’t be said for western markets. If swappable car batteries are going to become a reality, the tech needs to be supported by as many car brands as possible, and that’s a big ask. ——Source: thenextweb.com

  • Mobile World Congress canceled after coronavirus outbreak makes conference ‘impossible’

    Mobile World Congress canceled after coronavirus outbreak makes conference ‘impossible’

    2020-02-14
    Mobile World Congress (MWC), the world’s largest trade show for the mobile phone industry, has been canceled amid fears over the coronavirus outbreak. The organizers behind the Barcelona-based event, GSMA, announced Wednesday it would no longer be holding MWC due to ongoing concerns over the spread of a new strain of coronavirus which originated in China. “With due regard to the safe and healthy environment in Barcelona and the host country today, the GSMA has cancelled MWC Barcelona 2020 because the global concern regarding the coronavirus outbreak, travel concern and other circumstances, make it impossible for the GSMA to hold the event,” GSMA said in a statement. Multiple firms had pulled out of the tech conference prior to the GSMA’s decision, putting pressure on the hosts to drop the event. LG, Sony, Ericsson, Nokia, Nvidia, Intel and Amazon are some of the biggest names to have suspended their attendance in recent days. Various tech firms have been monitoring the health crisis, with some deciding to pull out of MWC as they assess the risk it would have on their staff. While plenty had backed out altogether, some had instead scaled back their presence. Huawei, for example, said it would send its European staff to Barcelona to cover for stranded Chinese employees. ——Source:CNBC
