The model for charging is Tesla. But Porsche and Audi are about to catch up. With the further development of Plug & Charge, they could even overtake.

The Porsche Taycan of the model year 2021 (Delivery since the end of October 2020) is Plug & Charge-capable according to ISO 15118. Identification and activation takes place automatically on Ionity columns. In addition, the integration of the shop in the route planner has been further improved.

Christoph M. Schwarzer The perfect charging of e-cars: Plug & Charge according to ISO 15118 – 20 Porsche and Audi with ISO 15118 ISO 15118 does not stop The e-car as local storage The role model and the yardstick for charging and route planning is still Tesla: the navigation system integrates the fast charging stations called Superchargers automatically. It precisely calculates the best strategy for the charging stops. On the superchargers themselves, all you have to do is plug the cable into the socket on the electric car: the identification of the holder and the activation of the electricity work via software. Meanwhile, the price in euros and cents is shown on the central display. Convenient, comfortable and transparent. This is the perfect store and a selling point for Tesla. The competition has understood that. Especially Audi and Porsche. The keyword for the software to catch up and potentially to overtake: Plug & Charge according to ISO 15118.

Tesla’s advantage was and is to this day the proprietary system of the Supercharger parks. The Californian company takes care of the fast charging stations itself. Only Tesla does that. The rest of the electric car industry, on the other hand, relies on infrastructure companies: Often it is traditional electricity suppliers such as EnBW or EWE who set up and operate charging points (CPO for Charge Point Operator). It was only with Ionity, a joint venture between the German car companies as well as Ford and Hyundai, that 2017 a competitive network for the superchargers on their own initiative. In individual aspects, it is now up to Tesla to draw level again: The Ionity columns offer a charging capacity of up to 350 kW. A value that will only be achieved with the next generation of superchargers. Currently, however, this charging capacity does not fully utilize a current electric car.

Um To achieve the same charging experience as Tesla – i.e. simply plugging it in with automatic identification and activation – theoretically all electric cars and charging points would have to have the same or at least fully compatible software and the necessary hardware. Because this can hardly be done retrospectively and only gradually for the future, Audi, Porsche and Ionity are starting now.
