Being able to charge quickly, environmentally friendly and at home are decisive purchasing criteria for many consumers when buying an electric car. Direct communication between the energy storage system and charging station is now possible with the Varta pulse neo. The energy storage system is equipped with a smart operating system and ensures interaction with selected charging stations without additional hardware. The software update thus enables operators of photovoltaic systems to use their solar power quickly and efficiently to charge an electric car.
A comparison shows: The costs at public charging facilities can be up to two euros per kilowatt hour (kWh). If, on the other hand, the vehicle is charged with normal household electricity, the gross cost is around 31 cents per kWh. The cheapest option is to charge with solar power from your own roof. This reduces costs by a further 50% compared to domestic grid electricity. Year-on-year comparison:
If the e-car is charged with electricity from the public grid, the annual electricity costs amount to around 1900 euros. If owners switch to a combination of solar power and energy storage, they pay around 270 euros per year for their total electricity consumption. The simplified calculation example from Varta shows a potential saving of around 1600 euros per year. Homeowners can also apply for subsidies. Various government agencies offer support for both energy storage systems and home charging stations. They usually have to be applied for in advance of the purchase.
