Thanks to BMW\u2019s<\/strong> new iX3 model<\/strong> and a special tariff developed by E.ON<\/strong>, vehicle owners can save up to \u20ac750<\/strong> annually. This equates to approximately 14,000 km of free travel<\/strong>.<\/p>\n\n\n\n

A joint effort between BMW’s<\/strong> new iX3 model<\/strong> and the power grid operator E.ON<\/strong> in Germany<\/strong> provides electric vehicle (EV) owners<\/strong> with the benefit of free charging equivalent to 14,000 kilometers<\/strong> annually.<\/p>\n\n\n\n

Electric vehicles<\/strong> have a vast, largely untapped potential. This potential both increases the efficient use of renewable energy<\/strong> and strengthens interest in EVs<\/strong>. The technology in question is called V2G (Vehicle-to-Grid)<\/strong>. Simply put, your vehicle no longer just draws electricity from the grid; it can also supply electricity to<\/em> the grid when needed.<\/p>\n\n\n\n

Balancing the Grid and Renewable Energy<\/strong><\/h2>\n\n\n\n

While renewable energy sources<\/strong> offer great environmental benefits, they create some challenges for grid stability<\/strong>. Electricity generation drops when there is no sun, yet an energy surplus<\/strong> occurs on the grid when there is an abundance of sun and wind. These imbalances often make grids reliant on expensive natural gas power plants<\/strong>.<\/p>\n\n\n\n

For this reason, grids are making multi-million dollar battery investments<\/strong>. However, most homes already have EVs<\/strong> with massive batteries parked outside. For instance, the BMW iX3\u2019s 108 kWh battery<\/strong> has the capacity to meet the electricity needs of an average home in Turkey for 6 days<\/strong>.<\/p>\n\n\n\n

Thanks to a professional wall charger<\/strong> and a special tariff developed by E.ON<\/strong>, BMW<\/strong> provides vehicle owners with both a bonus<\/strong> for the duration the car remains connected and additional earnings<\/strong> for the energy supplied to the grid. This system offers a maximum discount of \u20ac750<\/strong> annually. This means an iX3<\/strong> can travel approximately 14,000 km for free<\/strong> per year.<\/p>\n\n\n\n

From the grid’s perspective, this technology both eliminates the need for expensive emergency electricity<\/strong> and prevents investments in additional transmission lines<\/strong>.<\/p>\n\n\n\n

Battery Health and Control<\/strong><\/h2>\n\n\n\n

The energy provided from the vehicle to the grid is limited to 11 kW<\/strong>, which is the same level as normal charging power. BMW<\/strong> states that this low power transfer does not wear out the battery<\/strong>. Users can manage the system remotely<\/strong> and set a configuration to always maintain a minimum range<\/strong>.<\/p>\n\n\n\n

In the future, BMW<\/strong> will also make it possible to store excess solar energy<\/strong> during the day and use it at home in the evening with this technology. The “Neue Klasse”<\/strong> series, including the new iX3<\/strong>, will come standard with 11 kW bi-directional charging support<\/strong>. This could eliminate the need for a separate home battery<\/strong>.<\/p>\n\n\n\n

Furthermore, BMW<\/strong> plans to integrate the system with heat pumps<\/strong>. This way, users can direct excess solar energy to the home’s heating\/cooling system<\/strong> or the vehicle’s battery<\/strong>. In short, BMW<\/strong> is preparing to play a central role<\/strong> in home energy management<\/strong>.<\/p>\n\n\n\n

This technology provides an advantage not only for the home<\/strong> and the grid<\/strong> but also in outdoor settings<\/strong> like camping. The vehicle can turn into an uninterrupted power source<\/strong> for all electrical equipment.<\/p>\n\n\n\n

E.ON<\/strong> pays 24 Euro cents<\/strong> for every hour the vehicle is connected to the grid. However, the monthly payment ceiling is set at \u20ac60<\/strong>. This means the vehicle only needs to be connected for 250 hours a month<\/strong> (an average of 8.3 hours a day<\/strong>), which is a quite easily achievable goal in practice.<\/p>\n\n\n\n
