The Sion is a self-charging electric car. Integrated photovoltaic panels are charging the battery during the day, which makes the car a mobile power station.
The roof, bonnet, rear and the complete bodywork of the car consist of highly efficient mono crystalline silicon cells, which are covered by polycarbonate. We call this system viSono. Inside the car a natural air filter made out of moss called breSono. It regulates the humidity and filters fine dust particles.
The electrically powered family car with five doors and 4.10 m in length is equipped with five seats (2 + 3). A 80 kW motor allows a maximum speed of up to 140 km / h. An optional trailer hitch permits a tensile load of 750 kg.
The Sion has a range of 250 km under everyday conditions. The integrated charger allows you to charge batteries with power between 3,7 and 22 kW AC and 50 kW DC through a CCS charger. With a charging power of 50 kW, the batteries can be charged up to 80 % in 40 minutes. Therefore it is possible to charge the car with an average household plug.
Thanks to the function of bidirectional charging - biSono - you can also draw energy from the Sion and power your devices wherever you are. As a matter of fact you can also charge other electric vehicles.
The warranty of the Sion covers for two years - or up to 150.000 km. However, depending on the conditions we estimate the life of the Sion at 10-15 years. Generally, a long service life of the vehicle is for the Sono Motors GmbH of high importance, since we want to achieve real sustainability.
Therefore we have developed the reSono system, which is the maintenance system for the Sion. It guarantees low maintenance costs due to inexpensive spare parts. All components of the vehicle will be orderable with one simple mouse click.
viSono is based on the idea of "energy harvesting". Through the power of the sun, the battery recharges itself. Thereby the Sion can cover up to 30 kilometer per day - for free.
The integrated solar cells enables the Sion to go without recharging for several days. A total of 330 SunPower cells are producing 1,208 W peak at an efficiency of 24 %.
This amount could provide power for up to 40 km in one day. However, this is a theoretical maximum value which is highly unlikely to be achieved under real-life circumstances.
For the solar panels we use monocrystalline silicon cells. The modular units are pasted on a substructure, similar to the assemblage of a conventional windshield. Thereby the modular units can simply be exchanged.
The selection of the best material has highest priority. The components have to meet the following requirements: a service life of at least eight years, resistance against harmful environmental influences like ultraviolet rays and water, break resistance and a low weight.
Usually solar cells are laminated on top of 2 to 5 mm of glass. However, by comparison glass has a higher weight and is less break resistible.
For viSono we therefore use polycarbonate as support material. It is light, considerably more shatterproof and has a transparency index of .86 (glass: .8 to .9).
Thanks to the technology of bidirectional charging the Sion can not only generate but also provide energy. This feature turns the car into a mobile power station - also for other electric vehicles.
The outlet is accessible from the outside and is placed underneath the cap at the front. In order to access the outlet, the cap needs to be unlocked. This prevents unintended access.
Using a household plug, all common electronic devices with up to 2,700 W can be powered by the Sion. You can plug in your electronic devices and power them with the Sions battery. But that’s not at all.
Through the fast-charging plug it is possible to go up to 22 kW. In many areas electricity is being generated with the help of generators when there is no power supply nearby.
Usually, those are inefficient stroke generators, which are not subject to emission regulations. The Sion makes it possible to replace generators on construction sites, at events and during a situation of emergency. Mobile energy that is being generated ecofriendly – that’s the idea behind viSono and the bidirectional charging system.
Integrating one artificial filter was not enough for us. So we developed the breSono system. Besides the artificial air filter, we integrated moss into the dashboard and the center console.
It serves as a natural air filter, which further improves the indoor air quality and has positive effects on the humidity inside the car. Fine dust particles are first filtered by the artificial system and additionally cleaned by the breSono system.
Exclusive tests concerning its efficiency have shown that the moss filters 20 % of fine dust particles.
The system requires no care. Watering, fertilising, trimming or exposure to natural light are not necessary because the moss has no enzymatic reactions in this state. Even during hot summer days it doesn’t need any maintenance and is very durable.
When exchanging the artificial filter, you can easily exchange the moss too.
We used the moss for several years without any noticeable change. It has a high colour consistency and therefore keeps its exclusive natural look over many years.
In a special dyeing process, the microstructures which take water out of the air and release it when needed, are preserved, along with the other natural functions of the moss. In addition, this process protects the moss from staining from environmental influences, such as mould and pests.
breSono has the characteristic of a sponge and thus acts humidity-regulating. Humidity is either bound or released into the air depending on the level. At more than 50 %, the moss binds humidity and becomes soft.
At lower humidities, the moss releases the stored moisture and thereby becomes dry and somewhat harder. Both are natural states of the moss which do not alter its appearance.
reSono is the maintenance infrastructure of the Sion. It guarantees low maintenance costs due to inexpensive spare parts.
Most of the components of the vehicle will be orderable with one simple mouse click.
With the help of our step-by-step manuals everybody should be able to repair the Sion, single-handed and for free. We will offer the instructions as videos and texts on our website.
If you do not feel like repairing the Sion by yourself, just bring it to the next auto shop. Since we will unveil the complete workshop manual, every mechanic in the world should be able to repair the Sion.
We will not sell expensive repair shop licenses, nor will we develop software that only we can decode and fix. Our workshop manual is freely accessible for everyone on our website. Whether you’re a private person or a car dealer.
This helps establishing a broadly developed service network from the very beginning on - and guarantees you an affordable repair.
We also provide to each component of the vehicle the CAD file for free online, so as to let clients to have spare parts produced locally by CNC milling or 3D printer. This also means that companies can manufacture and distribute spare parts for Sion without a license from the Sono Motors GmbH. This has the result that plenty parts will be manufactured for the Sion and will always be available and the customer will benefit from the low prices of spare parts. The only drawback is that with non-commercial repairs and external produced spare parts, the (partial) warranty expires. But this is also the case with all conventional vehicles. We can not give a guarantee if a part has been replaced by you none professionally.
Generally, a long service life of the vehicle is of high importance for the Sono Motors GmbH, since real sustainability can only be achieved this way.
Once the vehicle has been produced and delivered, there will be a tab called reSono on our website. Here you can then reorder all parts of the vehicle. For some parts options are displayed, where you could get the concerned spare part somewhere else. For example, in the case of conventional screws. This shows you, whether you can buy it simply in your local hardware store. This saves waiting time and costs.
goSono combines three remarkable features of the Sion: powersharing, ridesharing and carsharing. By using your smartphone you can offer others electricity, a ride with your Sion or lend your car for a certain time.
Thanks to the technology of “bidirectional charging” you can use the car as an independent power source. With the “Sono”-App you can also share certain amounts of energy with other people. If somebody asks for access to your “Sions” energy, you can grant it via the app. Just decide on how much power you are willing to pass on and at what price. Other app users will see your offer and the exact location of your car. This transforms your car from an ordinary vehicle to a mobile power station, with which you can even earn money.
By using the "Sono App", you can easily offer travelers a ride with your Sion. Just enter the location your ride will be starting at, as well as your destination. Continue by making your ride available to others via the Sono App and set an individual price for the trip. Now other users can decide if they are interested in your offer and send a request. Once you accept it they will get a notice and you can pick them up. After reaching the destination you have agreed on, the money will be transferred directly to your account. Whether you commute or take a trip to another city: share the ride, share your costs.
The "Sono app" also makes it easy to share your Sion with other people. Use the app to decide on how long you want to share your sion. After parking, leave your keycard in the car and lock it using your phone. Now your sion is available for other app users to hit the road. Once somebody sends a request, he can reserve and unlock the car with your permission. When the car is returned, the rental charges are directly transferred to your account.
First, you will acquire a reservation to purchase the Sion. This comes with a right of withdrawal of two weeks. In a second step, Sono Motors will offer you a contract of sale for the Sion in 2019. This also comes with a right of withdrawal of two weeks. At first, the delivery will occur free of cost to Bremerhaven. For an additional charge, we will deliver the Sion to the location of preference. Reservations are possible worldwide. Test drives will take place at our own discretion.
The 16.000€ exclude the battery. Starting in 2019 we will offer the battery for a monthly rate (rent or lease) or a one time purchase. From today's perspective the one time purchase would cost you less than 4000€. The reason why we exclude the battery is because we want to offer you the latest available and therefore best price.
