    I don't know why I've been allowed to live, all these decades. God must have gotten between me & all the bribe-takers.

    How the Taycan Recovers Energy When Braking

    Porsche Taycan

    [​IMG]

    The German autobahn is empty and a Taycan driver is hauling @$$ at 125 mph until they see a delivery van passing a large 18-wheeler ahead. No problem as you slow down to 60 mph. A great deal of energy is consumed in the blink of an eye as non-electric vehicles brakes turn kinetic energy into copious amounts of heat through the discs. The Taycan however is an all-electric and automatically recovers a large portion of this energy, turning the electric motors into generators while slowing and storing the usually wasted energy in the large traction battery for later use.

    Kinetic braking energy increases twice as fast as speed – double the speed means four times the regen. When braking from 60 mph, the Taycan generates four times as much energy as when braking from 30 mph.

    How does the Taycan do that?

    Electric motors are normally controlled via both the rotation speed and torque running in the same – positive – direction. But each electric motor can function as a generator in which the motor continues to turn in the same direction but is now powered by the wheels rather than powering them itself. It generates electrical energy, rather than consuming it. And because it takes a lot of energy to power the motor and thus turn the rotor against the magnetic resistance, this negative torque is used to slow the vehicle.

    The control units and power electronics of the electric motors in the Taycan are intelligently connected with the controls and logics of the brake control system. The conventional hydraulic wheel brake and electric motors can slow down the vehicle together. Within milliseconds, the electronics decide what percentage of the braking will be electric and what percentage will be hydraulic. While the driver cannot feel the difference, they can see it in the power meter in the instrument cluster.

    Around 90 percent of everyday braking is 100 percent electric, allowing the Taycan to recover energy. In extreme situations, such as full braking from a top speed in a fully loaded Taycan, a maximum braking capacity of more than 2 MWs must be applied and the electric powertrain cannot absorb that amount of power on its own. The conventional wheel brake is then applied to shunt the excess. It may also activate because the battery is already full and can no longer recharge through regen. Thanks to the design of the electric motors and the electronics in conjunction with Porsche’s signature intelligent control, the Taycan can regen up to 290 KW, the approximate same power that we have charged it at. Porsche plans to increase that soon.

    Some OEMs have the electric drive’s regen system activate automatically the moment the driver removes their foot from the gas pedal, which is referred to as one-pedal driving. Porsche made the decision to have the driver apply the brakes to slow down, which is standard driving behavior.

    The Taycan secures around one-third of its range with the recovery of brake energy through Regen. And like all driving activities, you will achieve more range by forgoing regen as much as possible due to the conversion losses. In other words, anticipate the slow down with the long glide vs relying on the brakes over a much shorter distance. When possible, that is. ;)

    New Nürburgring Lap Record for the Porsche Taycan

    [​IMG] Not allowing a competitor to hold a performance record on their own soil, a production Porsche Taycan Turbo S achieves the fastest EV lap on the Nürburgring Nordschleife in history.

    Wayne Gerdes – CleanMPG – Aug. 10, 2022

    [​IMG]

    The record setting all-electric Porsche Taycan Turbo S sports sedan was equipped with a new performance kit and Porsche Dynamic Chassis Control (PDCC) – plus the mandatory roll cage and racing seats – as an entirely standard production vehicle. It weighed the same as the series production car. A notary was on hand to verify the new record time on the infamous 12.9-mile circuit in Germany’s Eifel region, while TÜV Rheinland confirmed that the record-breaking road car was a standard production model.

    The 2022 Porsche Taycan Turbo S with the all-new performance kit posted a lap time of 7:33.3 on the Nürburgring Nordschleife besting the previous record held by the Tesla Model S Plaid at 7:35.579.

    The performance kit includes 21-inch RS-Spyder-design wheels with road-approved, Pirelli P Zero Corsa sports tires that are now available for the Taycan. The tire compound is similar to racing tires. Another element of the performance kit is a software update to the Porsche 4D Chassis Control so that it works in harmony with the sports tires. The system analyses and synchronizes all the chassis systems of the Taycan in real time.

    Performance by Porsche Tequipment

    The performance kit is offered through Porsche Tequipment and is only available in Germany and only for the 2023 model year Taycan Turbo S sports sedan. Production of these cars started in late July 2022, while the performance kit itself is expected to be available from the end of the year. The plan is for the retrofit to be carried out after initial delivery, in the Porsche workshops in Zuffenhausen. Transport to and from the factory is included, as is the individual vehicle approval and registration of the Taycan.

    The sports tires are primarily designed for track driving and owners can switch back to standard tires at any time. It is not necessary to restore the original chassis software when doing this.

    Solar Fuels Growing Porsche U.S. HQ and Experience Center

    2022 Porsche Taycan Turbo S

    Charging sustainably on a proprietary 350 KW Charger at a Porsche Experience Center. ;)

    Porsche North America announced it has entered into a contract with Cherry Street Energy, LLC, the largest non-utility provider of solar energy in Georgia, to build and operate a solar power microgrid at One Porsche Drive – the site that combines PCNA corporate headquarters with the Porsche Experience Center Atlanta. A microgrid is an on-site electrical network with its own power source, in this case solar panels, that also connects to the wider electrical grid.

    The future solar power system at One Porsche Drive in Atlanta will include solar panels that will be installed over the next year on most new and existing buildings. This view of the expansion project from the west shows the state of construction as of August 2022, including the future second driver development track in the center.

    At One Porsche Drive, energy from solar will provide a significant portion of annual electricity needs. It will also mean the all-electric Taycan sports cars that are part of the visitor fleet can be charged from purely renewable power. The Experience Center, one of two in the U.S. and 10 in the world, is a track-based attraction where the public can drive the latest Porsche models with a personal coach as well as dine, shop or just grab a coffee in a Porsche-themed environment.

    The solar power project will contribute to PCNA’s sustainability goals as the campus adds major new facilities. One Porsche Drive is currently undergoing a $50 million development that includes building a second driver development track for the public, due to be operational in early 2023.

    New features of the development also include a Porsche Classic Factory Restoration facility, a parking deck and the already-opened Porsche Service Center South Atlanta. These developments are on 33 acres adjacent to the existing 27-acre headquarters and Porsche Experience Center, which first opened in 2015.

    Cherry Street Energy estimates the panels on the Porsche HQ campus will generate 2,050 megawatt hours (MWh) of electricity annually– enough to power 191 average homes for a year. Compared to using fossil fuel sources, this renewable electricity represents an estimated CO₂ reduction of 3.2 million pounds per year, equivalent to avoiding 3.6 million miles of driving by an average passenger vehicle.

    Installation of the solar microgrid will start in September and is expected to be completed in 2023, kicking off a 25-year operating agreement between PCNA and Cherry Street Energy. Panels will be mounted on new and existing buildings, the roofs of staging areas by the two tracks where customers start their drives, and on a new 950-foot covered walkway from the parking garage to the headquarters building. Cherry Street Energy will own, operate and maintain the microgrid, selling the power to PCNA. Through this direct transaction, Cherry Street Energy will provide stabilized energy rates and generate significant, measurable reductions in carbon emissions for Porsche.

    PCNA has made sustainability measures a priority for the campus expansion since the early stages on the project. In addition to the solar power microgrid, the campus will use concrete specially formulated to lower its embodied carbon content, benefit from extensive water re-use and recycling, utilize native non-irrigated landscape solutions, green walls and walking trails to increase biodiversity, and incorporate extensive new electric vehicle charging infrastructure. The new campus expansion is designed to achieve LEED Gold certification recognizing the high standards of Leadership in Energy and Environmental Design, which was previously awarded to the existing One Porsche Drive campus.

    What can my 2013 automatic Elantra do, that the Porsche cars can’t do? With my used, but over-sized 215x55x17 inch tires, which lift my Elantra about 3/4ths of an inch higher, I can rest my tires against wheel stops & curbs without causing damage. Gosh, such a relaxing feeling as I approach those stops & curbs, now!​
    Gee….even the 2016 manual Elantra, with the slightly over-sized tires can out-do the Porshce(Porsche).

    Yeah, yeah……some will say, “Buy an off-road truck”. :D:confused:
