Porsche wants to improve how we charge our electric cars


As Porsche prepares to launch the E mission in 2019, it naturally also hopes to strengthen its technology in the field of electric vehicles. In an interview with Porsche, Uwe Michael, head of the electrical and electronics division, talked about the battery direction and how the brand can improve the charging experience for future high-performance electric vehicles.

As we know, Porsche is deploying a Mission E-compatible 800-volt charging system. The 800-volt system allows the car to recover 249 miles in 20 minutes. But Porsche also hopes customers will be able to choose according to their own preferences wall charging output. Those who drive plug-in hybrids can choose 3.6 kilowatts of output, or 7.2 kilowatts if they drive slower. For electric vehicles, the choice of 11 to 22 kilowatts is appropriate.
Michael said charging experience should also be suitable for your route planning. With Porsche’s turbocharged charging program, electric car drivers can optimize quick charging options based on route. Porsche also wants drivers to reserve charging stations to save more time.

Porsche is one of many car manufacturers that have already explored inductive charging. However, Michael pointed out that there are many challenges in this regard. First, he said, this is just one option for family fees. “We are pleased that all Volkswagen Group brands are seeking a common solution,” said: “It will be a great help in setting a benchmark.
In order for a true take-off of an electric car, car makers must continually improve battery technology. Michael predicts that conventional lithium-ion batteries will increase efficiency by 5% annually for the foreseeable future. These incremental improvements will increase the dramatic increase in electricity. In the future, when customers want more juice, wireless updates can increase the car’s power.

Porsche is working on solid state batteries without liquid electrolyte. However, Michael does not think the technology will achieve its goal by 2025. Lithium-air technology is even farther apart and we are unlikely to see the technology in a production car until 2030.

With a level of automation of 5 in the future, BMW is the highest level of autonomy on the SAE scale. These vehicles do not require a steering wheel, brake pedal or accelerator as the vehicle itself controls almost all functions. However, according to Michael, level 5 is not a Porsche priority. On the contrary, automakers continue to move forward with the co-operation of rickshaws.
