If we are going to see something in the IAA of Munich, they are SUV cars. It is logical if we take into account the Importance of this type of vehicles in the marketbut the novelty comes by motorization. The great European Motor Show has become the catwalk of the electricity of the future and brands such as Volkswagen, Mercedes either LEAPMOTOR They are an example. But there is one that not only wants to present a more electric car: he wants to redefine the way of loading the car thanks to the inductive load.
As of tomorrow until September 14, Porsche will show his new Porsche Cayenne Electric and, curiously, in the release From the company’s press, only two characteristics have been detailed: its ‘electrofluorescent’ painting and something that they have baptized as ‘Porsche Wireless Charge’.
As the name implies, it is about a wireless load platform, Like a Magsafebut for the car. With all the good and bad that that entails.
Porsche Wireless Charge
First of all, load the car wirelessly It is not something new. BMW presented Your system a few years ago for the BMW 530e, In 2011 we already commented that the German company was developing that technology with Siemens and even third -party brands began producing their solutions.
Basically, it’s about platforms that we place on the ground and on which we park the car. Depending on where the inductive coil is placed that allows transferring the energy of the car battery to the car battery, all we must do is align that coil with the charger and ready, the car will begin to load. To guide us, the infotainment screen will give us information about the platform location.
What is new is the power. If BMW used a system with a load power of up to 3.2 kW, Porsche takes chest by stating that they will be the first to market A 11 kW load system. “The inductive load is applied to smartphones or electric toothbrushes,” says the company. And the operation of your system is literally, just like the one we have in the mobiles we use daily, but in a big way.
The floor plate does not need to be connected to a box on the wall or a control unit and has a transmitter coil that transfers the energy coil to the car’s receiver coil. It does it by air and it is the vehicle’s coil that converts this energy into direct current that can already be stored in batteries. This coil is among the front wheels and claim that it is protected against stones and atmospheric effects.
On the screen we see the load platform and we have aid to align the coils
It has considerable dimensions with 1.17 meters in length, 78 centimeters wide and six centimeters high and the brand states that it can connect both in garage -Obvio- and in an outdoor square. Weighs 50 kilos And the Cayenne Electric will be the first model “Optionally available with the pre -installation of Porsche Wireless Charge and the Porsche Wireless Plate.”
An interesting detail is that the plate has a movement detector and interrupts the load automatically if a living being stands between the vehicle and the plate.
Loading a car like loads a mobile has its inconveniences
There is an important issue that must be on the table. If you have a mobile with wireless load, you will have proven that it is heated much more when charged, so when we load it with the cable, and that the wireless load is usually less powerful. This is because, if the cable reaches high levels of energy transmission efficiency, with the wireless load the same does not happen.
In the process there is a loss of heat in the form of heatand this is what prevents the power from being so high, it is what heats the phone and, in addition, You need more energy to work. To minimize this loss of energy, when Cayenne is carrying on the base, its profile is automatically lowered to be as close as possible to the base, and Porsche states that the efficiency of the transfer leads to 90%, so only 10% is lost in the form of heat. That heat, by the way, should not directly impact the battery, since the load coil is not so attached to the batteries as in a mobile.
Although this “but” is on the table, it is evident The gain in comfort supposed by wireless loading systems. At home we see it with mobile phones or toothbrush, but in a car it can be key when facilitating the installation of the cargo point at home. And not only at home: imagine a large professional fleet of electric vehicles that are loaded in their square without installing a load point for each or for every two cars. Even wireless load points on public roads.
The expansion of the load network is crucial for the adoption of electric cars. We have seen it recently in the Netherlands, where a significant increase in load pointsbeing next to Norway –Paradise of the electric– One of the European countries with the best loading infrastructure. “The ease of use, the utility for day to day and the load infrastructure remains decisive factors for the acceptance of electric mobility,” they say from Porsche, and wireless load platforms can mean a differentiating point in that change of mobility.
At the moment, 11 kW is a maximum ridiculous power if we compare it with the 400 kW of CC to which the cable cayenne can load, but the good thing that marks like BMW in its day and Porsche now will now implement this type of systems is that, Little by little, the power will rise and will reach lower ranges cars. In fact, that this technology debuts in Cayenne is a declaration of intentions: it is the most popular car of the brand (Regarding sales).
After all, it is something we already saw with mobile phones. And many cars already They are more a smartphone with wheels than a car.
