[EVDL] EVLN: Heathrow airport's 200 Jaguar I-Pace EV shuttle fleet
https://evcult.com/content/jaguar-i-pace-suv-fleet-be-used-offering-shuttle-services-heathrow-airport Jaguar I-Pace SUV fleet to be used for offering shuttle services from Heathrow airport 10 May 2018 James Esplin [image https://evcult.com/sites/default/files/styles/large/public/field/image/Jaguar-I-Pace-EV.jpg?itok=chX_sxum I-Pace ] British automaker Jaguar has revealed in a recent announcement that a fleet of its all-electric I-Pace SUVs will be used at the Heathrow airport, for offering shuttle services. The automaker also said that the use of I-Pace SUVs at the airport will start during “the summer 2018.” The announcement is noteworthy because even though the Jaguar I-Pace SUVs are still to arrive in the market, the large orders which Jaguar has received for the vehicle has already resulted in a considerable backlog. According to Jaguar’s recent announcement, the automaker has received an order of 200 I-Pace SUVs for shuttle-service use from the Heathrow airport. For building up a fleet of the I-Pace SUVs, the airport has teamed up with Jaguar and WeKnowGroup travel services firm. The latest order for I-Pace SUV fleet of 200 vehicles for the airport is an apparent indication of the increasing popularity of all-electric vehicles for taxi services at airports. With regard to the delivery of the 200 I-Pace SUVs for the airport, Jaguar said that the first 50 units of the vehicle will be delivered this summer, with the remaining 150 units to be added to the fleet “over the next 12 months.” Jaguar has also revealed that a charging station will be installed at the Heathrow airport to support the I-Pace SUV fleet.

Since its introduction in 2010, Nissan has sold more than 300,000 Leafs, making it the best-selling electric vehicle in the world. The second-generation Leaf is powered by a 40 kWh lithium-ion battery with a range of 151 miles on a single charge. Our test car came with Nissan's optional ProPilot Assist semiautonomous-driving tech. We found the Leaf to be a pleasant and capable EV, but the 151 miles of range is lacking when compared to its rivals. The Nissan Leaf starts at $29,990 while our top-spec test car carried an as-tested-price of $37,865. The Nissan Leaf is a true pioneer in the electric-car game. The Leaf's combination of perky performance, 100 miles of range, and easy-to-use demeanor made it a popular choice for those looking for pure electric mobility. Generous government incentives also helped move cars off dealer lots. Since its introduction in 2010, Nissan has sold more than 320,000 Leafs globally, making it the best-selling electric car in the world. But alas, time and tide wait for no man. Since 2010, the benchmark for EV performance has changed drastically. For consumers, 100 miles of range is no longer enough, especially after the release of the comparably priced 238-mile Chevrolet Bolt and the 220-mile Tesla Model 3. (Note: Tesla's 220-mile Model 3 has not yet reached production. The company is only producing the longer-range 310-mile version, which retails for upwards of $55,000.) The Tesla Model S and Model X have set new standards for speed and utility, albeit at a much higher price. So for 2018, Nissan introduced an all-new second-generation Leaf, one that's better equipped to handle this latest wave of competition. "This is the car of the future, today," Nissan North America chairman Denis Le Vot told Business Insider in an interview at the 2018 New York Auto Show. "In that sense, it is a flagship of the company's technology." In addition to the Leaf, Nissan plans to launch eight fully electric models by 2022, Le Vot said. Earlier this year, Nissan dropped off a blue 2018 Leaf for us to check out. It starts at $29,990 while our top-specced SL tester started at $36,200. With options, our Tennessee-built car carried an as-tested-price of $37,865. It should be noted that EV tax incentives could knock thousands of dollars off the sticker price depending on where you live. Here's a closer look at the 2018 Nissan Leaf: [images] / Hollis Johnson/Business Insider ... From 2010 to 2017, the Nissan Leaf sold at an unprecedented rate for an electric car. 2017 Nissan LEAF. Nissan But with the advent of new, higher-mileage models likes the Chevrolet Bolt and ... Hollis Johnson Tesla Model 3, it was time for Nissan to update its stalwart EV. For 2018, Nissan is back with the second-generation Leaf EV. Aesthetically, there's a lot more to like about the new Leaf than its predecessor. Gone are the soft curves and funky bug-eye headlights. In their place, is a more aggressive and chiseled look. Overall, we found the Leaf's styling to be handsome and modern. Even though the new Leaf looks and feels larger, its length, width, height, and weight remain virtually unchanged from its predecessor. Even the 0.28 drag coefficient remains the same. Inside, the Leaf effortlessly blends tech with familiar Nissan touches. It's modern without feeling too futuristic or weird. And the tech features are abundant. Leading the way is Nissan's new ProPilot Assist semiautonomous-driving system. ProPilot is a camera-based system that stitches together input from the car's steering assistance and intelligent cruise control tech to create a semiautonomous-driving experience. The system works pretty well and will keep you from swerving out of your lane. But ProPilot is purely an assistance feature, so you'll need to keep your hands on the steering wheel at all times. This is something Nissan has been very clear about. Nissan has also been working on single-pedal operation for the Leaf. Using the new e-Pedal, Leaf owners can effectively drive without using the

The newlyweds shared tears, laughter and a passionate kiss in front of their hundreds of VIP guests dominated by Hollywood stars including the Clooneys, the Beckhams, Idris Elba, Oprah Winfrey, Tom Hardy and James Corden. [image] This evening the royal couple, the newly created Duke and Duchess of Sussex, headed to their reception at Frogmore House, a 17th-century venue in the grounds of Windsor Castle. About 200 guests were due to join the couple at the evening event at the Frogmore mansion, where Meghan was due to make a speech to guests. They travelled in a silver blue Jaguar E-Type Concept Zero, which was originally manufactured in 1968 and now runs on electricity, to the English country house which stands in the home park of Windsor Castle and is part of the Crown Estate. It is only open to individuals on three days of the year. Actor James Corden, who attended the ceremony earlier with his wife Julia Carey, is set to play the role of host and entertainer for the reception, it is reported. Guests invited to Frogmore House, a royal estate in Windsor Home Park, were given a few hours after the lunch to rest and change outfits. The bride's evening dress is designed by Stella McCartney and is a bespoke lily white high neck gown made of silk crepe, while her Aquazurra shoes are silky satin with soles painted in baby blue. A double decker coach full of guests arrived at the entrance to Frogmore House for the evening reception at 7.15pm. The coach had arrived from Coworth Park hotel in Ascot, where Princes Harry and William spent the night before the wedding. Princesses Beatrice and Eugenie arrived in a black Bentley at 7.30pm. Earlier Meghan became the first mixed-race member of the royal family in an extraordinary journey for a girl born in LA to a white father and African-American mother who fought her way through the tough world of showbusiness to land a plum role in the TV series Suits. Harry and Meghan's big day couldn't have been more different than royal weddings of the past, especially because the prince was visibly emotional throughout - and guests suggested it was the most diverse major event in the Queen's 66-year reign.

These battery banks, typically made up of lithium-ion (Li+) cells, can achieve operating voltages higher than 800V. However, the materials of this battery chemistry can be damaged if overcharged. Each cell voltage must be monitored and, if necessary, appropriate control methods must be applied to avoid overvoltage. Excessive cell leakage current, overvoltage, undervoltage, and extreme temperature can all lead to weaker performance or even catastrophic failure. This article reviews the structure of a typical electric vehicle (EV) battery and highlights many concerns associated with its complexity and safety. We then introduce a novel battery management system that overcomes these concerns, allowing EV power system engineers to design with confidence. SENSORS EXPO & CONFERENCE Sensors 2018 Hits Silicon Valley June 26-28! Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems. EV Battery Structure The typical EV battery depicted in Figure 2 is made of 6720 Li+ cells, managed by eight control modules. Each cell has a capacity of 3.54Ah, adding up to a total battery nominal energy storage of 100kWh (3.54Ah x 4.2V x 6720 cells). The series of 96 rows, each made of 70 cells in parallel, add up to a battery voltage of 403.2V (96 rows x 4.2V), with a capacity of 248Ah (100kWh/403.2V or 3.54Ah x 70 columns). This allows an EV to travel 300 miles at a speed of 50mph for 6 hours before exhausting the battery. The EV motor will draw an average current of 41A (248Ah/6h). Data Link In the daisy-chain configuration of Figure 2, all the control modules communicate serially with a central microprocessor via IC1; isolation is required between the microprocessor and the first module, and from one module to the next. Alternatively, in an isolated controller area network (CAN) configuration, a more cumbersome solution is necessary since each module requires one microprocessor and a CAN IC, in addition to the BMS IC. The data link must reliably operate in noisy high-power battery environments, where both the high dV/dt supply noise and common-mode current injection (induced by electromagnetic fields) are present. Cell Diagnostics Many things can go wrong in a battery pack. Excessive current leakage, high or low voltage, and extreme temperature of the cells can all lead to weakened performance or even catastrophic failure. The manifestation of these faults varies with the battery cell configuration. In a series stack of cells, voltage variations are more readily spotted, while in parallel configurations, the leakage current becomes amplified. In a mix of series-parallel configurations, like the one in Figure 2, deviations in leakage current are more readily measured while voltage deviations induced by a single bad cell are attenuated and require measurements with a higher level of accuracy. Cell Balancing Li+ and lithium-polymer battery chemistries cannot be overcharged without damaging their active materials. In a string of cells in series, the state-of-charge (SoC) of each cell voltage must be monitored, and if necessary, appropriate control methods must be applied to avoid overvoltage due to overcharge. Cells in parallel tend to be self-balancing since the parallel connection holds all the cells at the same voltage preventing runaway voltage of a single cell. Accordingly, in a matrix of cells such as in Figure 2, the monitoring proceeds by a row of cells, rather than a single cell. Each module in Figure 2 contains all the electronics necessary to perform balancing by means of arrays of

The automaker has shown off heavily camouflaged prototypes of its EQC SUV with word that the production model is on track to launch in 2019. Test mules already endured "tough" winter conditions in northern Sweden between January and March, while upcoming trials will check its powertrain and suspension. It won't be a gentle summer for the EQC, as Mercedes is subjecting it to a heat stress test in Spain. The EQC is leading Mercedes' entry into from-scratch EVs and should be competitive with the likes of Tesla's Model X and Jaguar's I-Pace. The twin-motor vehicle pumps out roughly 400HP and is estimated to drive up to 310 miles on a charge, albeit on an outgoing test cycle (US EPA figures are likely to be lower). Its main advantage is likely to be that three-pointed star on the front -- it's an upscale electric vehicle with a familiar name and a (mostly) familiar approach to design.

That's a plea from makers of the lithium-ion batteries that typically power our phones, laptops and even power tools. Thrown into the trash or even the recycling bin, they can cause fires at trash and recycling centers. Last year, 65% of waste facilities fires in California began with lithium-ion batteries. And when one goes, others can, too. "If there are multiple batteries there, you will have not just a fire, you will have explosions,' said Carl Smith, CEO and president of Call2Recycle, a national recycling program funded by battery manufacturers. It's such a big problem that this week, California has launched an awareness campaign to try to get consumers to keep these ever-so-useful but also potentially dangerous items out of garbage trucks and landfills. It's part of a national effort to keep increasingly common batteries from causing fires. Those fires can be devastating. In March, an improperly disposed of lithium-ion battery caused a five-alarm fire at a recycling facility in Queens in New York City. It burned for two days and shut down four branches of the Long Island Rail Road for several hours, due to the thick smoke blowing onto the tracks. That same month, an Indianapolis recycling plant also shut down after a fire blamed on batteries. Last year, a lithium-ion battery thrown into the trash caused an explosion in a New York City garbage truck when the workers compacted the waste, igniting and exploding the battery. Lithium-ion batteries are found in cell phones, laptop computers, cameras and rechargeable power tools and even the electric scooters that have risen in popularity in the past year, says Kerchner. They also power electric cars like Teslas and Chevy Bolts. When it comes to the lithium-ion batteries in everyday devices, consumers tend to put them in the recycling "hoping that somebody at the end of the line will recycle them eventually,' said George Kerchner, executive director of the Rechargeable Battery Association. We use a lot of them. In 2017, 175 million pounds of lithium-ion batteries were sold into the U.S. market, according to Call2Recycle. The problem with lithium-ion batteries is the same thing that makes them so great - they're small and light but still pack a serious energy punch. These are the same kind type batteries that were catching fire in the recalled Samsung Galaxy Note 7's - as well as many other Samsung and other phone models that don't regularly explode. Even when they've pooped out in your device, there's still enough charge in them that they can create a spark if the terminal of the battery - the metal bits that send power from the battery into the device, touch something metallic, like the side of a garbage truck. This can close the circuit, which creates an electric charge that can create a spark. "And sparks create fires. If it's at a recycling facility where it's mixed in with paper and other items that are burnable, that just goes up like you wouldn't believe,' Smith said. "These are high-energy batteries, no question about it. If they're not properly handled they can catch on fire, Kerchner said. What to do with them Some areas' recycling programs have special battery recycling. For example, in San Francisco, you can leave batteries in a bag on top of your recycling bin on trash day and the local trash company will take them away to be recycled. Nationally, lithium-ion batteries can be recycled at all Home Depots, Lowes and Best Buy stores. If you put them in your recycling bin, put them in a closed plastic bag so that the battery can't come into contact with metal. A Ziploc bag or something similar works well, said Smith. Don't put them in the regular garbage, which is typically crushed and shredded. That can cause fires and even explosions. A less optimal but possible solution is to wrap either electrical or duct tape aroun
