DAF supplies the cab and chassis of the DAF CF truck, crowned 'International Truck of the Year 2018’, and VDL supplies the electric motor, batteries and the associated controls.
The battery system in the Audi e-tron is located beneath the cabin and is 2.28 meters (90 inches) long, 1.63 meters (63.6 inches) wide and 34 centimeters (13.4 in) high. It comprises a total of 36 cell modules in square aluminum housings, each of which is roughly the size of a shoe box. They are arranged on two levels, known as “floors” – a longer lower floor and a shorter upper one. At market launch, each module is equipped with twelve pouch cells having a flexible outer skin of aluminum-coated polymer. The battery operates with a nominal voltage of 396 volts and stores 95 kWh of energy.
The centerpiece of the Mercedes-Benz EQC is the lithium-ion battery, which serves as the energy source for the two electric motors. It is manufactured in-house at Deutsche ACCUMOTIVE in Kamenz.
The battery is comprised of 384 cells arranged in the vehicle floor between the front and rear axle. It is divided up into two modules with 48 cells each and four modules with 72 cells each. The powerful high-voltage battery with a voltage of about 350 V has a usable energy content of around 80 kWh. Depending on the cycle, this makes a range of more than 450 km possible (measured in NEDC). The safety of the batteries was also affirmed in different crash tests. In addition, the low and central arrangement improves the handling of the EQC.
Hybrid technology offers considerable potential for CO2 savings, with maximum flexibility in terms of applications: electrification of auxiliary components, mild hybrid applications with 48-volt drive motors in parallel (recuperation/boosting), high-voltage or serial architectures, and plug-in hybrids (purely electric driving for long distances).
48-volt system: 10 percent less CO2 in distribution transport
For light- and medium-weight commercial vehicles up to 12 metric tons in distribution transport, MAHLE offers a robust, compact 48-volt drive system with water cooling and integrated electronics, providing a power output of up to 30 kW. Because of the low level of waste heat from the electric drives (boosting/recuperation) connected in parallel, the cooling architecture used for vehicles with a combustion engine or battery can be adapted easily and effectively for this price-sensitive application area.
Consistent use of electrically driven, beltless auxiliary components—such as electric fans, electric air conditioning compressors, or electric main coolant pumps—can produce a total CO2 savings potential of around 10 percent in urban distribution transport.
