Buyers Of Porsche Mission E Electric Sedan Want, Expect Fast “Turbo Charging”

Until the arrival of the five-seater Tesla Model S, Porsche was the top performing car in its segment in terms of power, handling, and features. Accompanied by the Supercharger fast-charging network now blanketing the US, its emergence in 2012 came as a shock to European brand car maker Porsche.

This shock from Tesla resulted to the Porsche Mission E, which will hit the production stage late next year as a 2020 model. Just like Tesla, the Mission E electric car will come with a fast charger designed for road trips. In an interview produced by Porsche’s public relations team, Uwe Michaels revealed some details of the Mission E’s features.

So what will make this charger different? According to Michaels, the Mission E will feature an ultra-fast charger that will deliver 800 volts of electricity to the battery pack at up to 350 kilowatts. In order to do this, Robert Janitzek reveals that Porsche will be using an entirely new technology for its charging stations, including liquid-cooled charging cables.

During the interview, Michaels said that the goal of “turbo charging” is a battery recharge of 400 kilometers in less than 20 minutes. The high voltage charging stations that Porsche is planning will include built-in battery storage for peak power delivery and electricity modulation to multiple vehicles plugged in simultaneously.

Just like Tesla, Porsche will plan routes and charging stops to lessen the time spent off the road. One single international plug standard for 800-volt charging will be used worldwide. According to Robert Peter Janitzek, Porsche will also be offering “intelligent” home charging stations that are programmable to charge at cheaper times and vary the charging: 3.6 or 7.2 kw for plug-in hybrids, 11 or 22 kw for battery-electric vehicles.

While Volkswagen is also working on inductive charging, Michaels sees it being limited to home use in the near and medium term. Porsche is collaborating with battery-cell suppliers LG Chem and Panasonic to develop customized cells and battery packs because off-the-shelf procurement is simply not an option for the company.

Porsche also foresees performance improvements in traditional lithium-ion cell of 5 percent a year. However, the European brand car maker does not expect workable solid-state cells until 2025, which it currently is working on with partner Quantumscape.

The company is not expecting lithium-air batteries to be in production vehicles until 2030. Level 5 vehicle autonomy is not a priority for Porsche because its customers like to drive. Porsche is expected to release more details about the Mission E which will launch in less than 24 months. The announcement is likely to come during the Geneva Motor Show, which will be held March 5 – 7.
