The new Volkswagen ID.3 - E-engine and battery

The electric motor of the ID.3 is located in the rear and generates 150 kW (204 hp) of power and 310 Newton meters (Nm) of torque. The proven rear-wheel drive in the first generation ensures agile handling and good traction, as well as a small turning circle of 10.3 meters. The drive is provided by a permanently excited synchronous machine (PSM) with high efficiency: its efficiency is significantly above 90 percent in the vast majority of driving situations. The electric motor is positioned above the rear axle and sends its torque to a two-stage 1-gear transmission with differential. The drive unit, including the power electronics that process the control signals and switch the currents, weighs only about 90 kilograms. The ID.3 is still available with two different battery sizes: 58 and 77 kWh. The lithium-ion battery significantly contributes to the all-round character of the ID.3: with its 77 kWh net battery energy content, the large battery provides the ID.3 Pro S with a range of up to 546 kilometers (WLTP). For the ID.3 Pro with 58 kWh net battery energy content, it is up to 426 kilometers (WLTP). The flat battery housing built into the vehicle floor consists of aluminum profiles and is protected by a massive underbody guard and a strong frame. Inside, the cell modules are located, each of which contains 24 cells with a flexible outer shell. A base plate with integrated water channels keeps the modules at their ideal operating temperature of 25 degrees Celsius - this brings advantages in power output, DC charging, and service life. After eight years in operation or 160,000 kilometers of driving distance, the battery still retains at least 70 percent of its original net capacity - guaranteed by Volkswagen.
