The ramp-up of e-mobility is accelerating and the variety of models is increasing. The challenge is to further increase the customer benefits of electric cars, to minimize their CO2 balance and to be able to offer the vehicles more cheaply. The German engineering specialist IAV has designed a modular platform that should make the development of electric drives faster, cheaper and more sustainable – from small cars to light commercial vehicles.
“Platforms are a key to mastering the diversity of variants and to reducing development time and, in particular, product costs through economies of scale,” says Erik Schneider, Head of the E-Traction & Hybrid Drivetrain department at IAV. The e-drive train platform developed by IAV enables the combination of scalable and modular systems, e.g.B. Battery and electric motor, a large variety of variants for all vehicle segments and their drive topologies.
The platform is designed to cover a power range from 100 to 440 kW, battery capacities from 27 to 115 kWh and voltage levels from 400 to 800 volts, and enables the use of both silicon (Si) and silicon carbide (SiC). In addition, under the aspect of openness to technology, there are numerous additional functions such as all-wheel drive and torque vectoring to increase driving dynamics.
As possible examples of specific vehicles, IAV cites a small car weighing 1200 kilograms, a range of around 380 kilometers and a maximum speed of 180 kilometers per hour. For a mid-range sedan weighing 1700 kilograms, a maximum range of 500 kilometers and a top speed of 225 kilometers per hour are possible. The light commercial vehicle, weighing 2500 kilograms, has a maximum range of 250 kilometers and can reach speeds of up to 160 kilometers per hour.
In total, IAV has virtually generated and evaluated around 24 million technically feasible powertrain variants. Using simulation tools such as.B. IAV’s powertrain synthesis systematically varies and combines the main battery, electric motor, inverter and transmission systems. “With the modular e-kit, we cover the requirements of the entire fleet defined by us,” explains Rene Kockisch, Team Leader System Development Mechanics at IAV. The developer can also vary within the vehicle classes – for example in the case of an SUV from the low-cost solution to the high-performance version.
IAV attaches particular importance to the topic of sustainability, according to the company in a current press release. Based on a comprehensive life cycle analysis, IAV has developed a special eco-design for the battery platform. This should be a resource-saving solution that contributes to the fact that less CO2 is emitted in battery production than in the production of classic electricity storage devices through better material selection, connection technology, disassembly and recycling.
