Truss structure made of aluminium. The battery housing of the ID.3 is an aluminium lightweight structure in a scalable truss design. The housing is bolted to the body and thus supports the latter’s rigidity. Its compartments accommodate the battery modules, which each integrate 24 pouch cells with a flexible outer sleeve.
The battery systems, which are supplied by the Volkswagen plant in Braunschweig, are 14 centimetres high and 145 centimetres wide. They have a length of 144 centimetres (ID.3 Pro Performance) and 182 centimetres (ID.3 Pro S) respectively. The smaller battery integrates nine modules in a housing with ten compartments, while the large battery comprises twelve modules, which are accommodated in a truss structure with twelve compartments. This battery tips the scales at 495 kilograms.
Complex thermal management. The temperature of the cell modules is regulated by a base plate with integrated water channels which is connected to a coolant circuit with air conditioning compressor and electric heater. The thermal management system is designed to ensure that the battery is as far as possible operated in the ideal temperature ranges in all situations. This results in benefits for power output, fast DC charging and the battery service life. Volkswagen guarantees that the battery will still have at least 70 percent of its original capacity after eight years of operation or a mileage of 160,000 km. A second coolant circuit in the ID.3 supplies the electric drive motor, the power and control electronics and the charger.
Charging ecosystem. Together with the ID.3, Volkswagen is launching a comprehensive overall package for convenient and sustainable charging of electric cars under the name We Charge. This offers the appropriate solution for every charging scenario – whether at home, on the move or for long-distance journeys. The We Connect ID. app provides customers with convenient access to the charging ecosystem.
Charging at home. When the car is parked in the garage at home, ID.3 owners can charge the vehicle with certified Volkswagen green electricity from renewable energy sources supplied through the Volkswagen subsidiary Elli. This is best done using the ID. Charger, the new home charging station from Volkswagen. It is available in three versions, all of which offer a charging capacity of up to 11 kW. This allows an empty vehicle battery to be fully charged again in around six to seven and a half hours,depending on the model. The ID. Charger base model currently costs only 388 euros. The ID. Charger Connect and ID. Charger Pro offer full connectivity and can be controlled with the We Connect ID. app via smartphone.
Charging when on the road. ID.3 customers can charge at public charge points using the Mode 3 cable supplied as standard. With the We Charge service, they can use one of the largest charging networks in Europe with more than 150,000 public charge points. They can access these using the We Charge card. Customers can choose from three tariffs, depending on how intensively they use their ID.3.
Charging on the motorway. The ID.3 is equipped as standard with a CCS charge port (CCS = Combined Charging System), which also allows it to be charged with direct current (DC). The possible DC charging power is up to 100 kW for the ID.3 Pro Performance. The ID.3 Pro S achieves up to 125 kW – the charge level of its battery can be increased from 5 to 80 percent in around half an hour, enough for the next 350 km. Through the IONITY, Volkswagen is participating in creating of a high-power charging network on European motorways with 400 planned locations. We Charge customers can charge at IONITY charging stations at favourable rates starting from 30 cents per kWh.
Expansion of the charging infrastructure. By 2025, Volkswagen Group will install around 35,000 charge points in Europe itself together with its retail partners. Many of these will be publicly accessible. These will be complemented by the flexible, fast charging stations from Volkswagen Group Components, which can be set up wherever there is a short-term need, such as at major events. They become fixed charge points through connection to the low-voltage network and can charge two electric cars simultaneously with up to 150 kW thanks to their fast charging technology.
