From now on, idMany models in the range now offer bi-directional charging with vehicle-to-home functionality. Thanks to the home power station and the integrated home energy management system (HEMS) from Volkswagen partner Hagerenergy GmbH, customers can meet as much of their household consumption as possible with a photovoltaic system. Both companies have launched a pilot project in Sweden to provide vehicles and the corresponding charging infrastructure for entire residential areas.
We are actively shaping the energy transition with our products and services focused on electric vehicles: With the bidirectional charging capabilities that are now available, we have tailored new services to the needs of our customers. Not only do they save energy costs, but they also make an important contribution to the sustainable use of energy," says Imelda Labbé, Member of the Board of Directors of Sales, Marketing and Aftermarket at Volkswagen.
ID. with 77 kWh battery (net).The model will be able to store electricity at home using bidirectional charging. Volkswagen will also be able to activate the feature for vehicles already delivered through an update, as long as they also receive an IDSoftware 35。Due to the large storage capacity, the house can also provide solar energy to the house on cloudy days or in the evening when the sun goes down and the photovoltaic system is no longer powered. This means that customers can decide for themselves when to draw energy from the public grid or use the self-generated energy stored in the vehicle's battery.
In addition, thanks to ingenious electricity prices and algorithms, it is already possible today to charge cars precisely when a large amount of renewable energy is available. For example, wind turbines don't have to be shut down because there are no consumers. Electric vehicles can deliver unwanted electricity to the customer's home grid (vehicle-to-home) and can also provide power to stabilize the grid in the future.
The farm, converted into the foundations of a new settlement, has been around for about 350 years. Swedish entrepreneur Klas Boman wants to make these houses sustainable for the next 350 years by retrofitting them: "Stenberg is a once-in-a-lifetime project. When we decided to realize the "Another 350-Year Project", energy and the environment were key. Every decision takes these aspects into account. Consider using electric vehicles as energy storage from the outset. Thankfully, Volkswagen joined the project in April 2021, and we're ready now. This will be one of the biggest changes in the energy market.
This makes Volkswagen one of the first bidirectional charging solutions based on the CCS (Combined Charging System) DC charging standard, which is widely used in Europe. Bidirectional charging is based on ISO Standard 15118-2, which describes the communication between an electric vehicle and a wall-mounted charging case.
id.The bidirectional charging function of the model combined with DC charging technology is a dynamic extension of the home energy storage system. This takes over the main energy source of the house**. When the home energy storage system needs additional energy, the vehicle is activated by the home power station. Once the home storage system is charged, the vehicle stops transmitting energy and goes into standby mode. This means idIt is only activated when additional energy is needed.
Assuming that the average electricity consumption of a house is about 30 kWh, it can provide about two days of electricity. High-voltage batteries cannot be discharged below 20% state of charge to ensure readiness for movement.
In the first version, the relevant IDModels are only compatible with HagerEnergy GmbH's S10 E Compact series DC home power stations. Other domestic power stations will enable bidirectional charging stations (wallboxes) to operate at a later date.
