electromobility is gaining ground all over the world. More and more electric cars are helping, the environmental impact of conventional internal combustion engines to reduce. For a comprehensive sustainability concept, it is appropriate to in-house solar system for charging the electric car to be used. Click here to find out how this works and what the benefits are.
Charging an e-car with a wallbox
The number of public charging stations for electric cars is to be significantly increased in germany in the coming years. If you don’t want to wait for that, but want to charge your electric car right outside your own front door, there’s a private charging station in the form of a wallbox to recommend.
Compared to a household socket, such a wall charging station offers a particularly high level of safety and at the same time a significantly higher charging capacity. While a household socket can be used for charging with a power of approximately 2.3 kw, a wallbox can be with a wallbox up to 22 kw around ten times as much. This means that the battery of an electric car charges up to twenty times faster via a wallbox than via a conventional power socket.
The purchase of such a charging station beats with about 1.500 to 3.000 euros to be paid. It must be registered with the grid operator. From a charging power of 11 kw is a wallbox also subject to approval.
charge the electric car via the PV system
An e-car can be charged if it has its own photovoltaic (PV) system to be charged with solar power.
The larger the PV system or. The lower the energy hunger of other consumers in the household, the more solar power can be used via a wallbox compatible with solar systems be fed into the electric car. The additional use of an energy management system makes it possible to selectively increase the power supply for the electric car when things have to happen quickly.
If the PV system does not produce enough electricity to charge the electric car due to insufficient solar irradiation, external mains power can also be switched on.
When charging an electric car with solar power, it should be borne in mind that an electric car is usually at least 1.4 kw can be charged must. If you want to be on the road with solar power in your battery, you have to make sure that your own PV system can supply this 1.4 kW in addition to your regular household power consumption. Our article on the power requirements and power consumption of electric cars provides you with further information on this topic.
promotion of solar power for electric cars
Owners of apartments have so far been dependent on all members of a homeowners’ association must agree to the installation of a charging station. tenants had to obtain the landlord’s consent.
With the adjustment of rental and home ownership law the policy in november 2020 cleared the way for apartment owners and tenants to install a wallbox more easily. As a financial incentive, the state provides a subsidies for private charging stations total amount of 200 million euros. So you can a subsidy for the purchase and installation of a private charging station including grid connection and energy management system in the amount of 900 euros per charging point apply (as of the end of 2020).
