BMW Electric Car Developer: Theme Sustainability Ranges

Stefan Juraskek, at the automobile manufacturer BMW responsible for the development of electric drives, spoke in a company published on BMWS press page in detail about the company’s e-mobility efforts, the coming fifth generation of BMW electric drives and the sustainability of battery cells.

In the fifth generation of the BMW electric drives, which is to be used for the first time from 2020 in the electro-SUV BMW IX3, form “the E-machine together with gearboxes and power electronics a new, highly integrated E-drive component,” says Jurasket. “This very compact unit claims much less space than the three individual components of the previous generations,” he explains. In addition, the drive is scalable thanks to its modular structure and can be adapted to a wide variety of structural spaces and performance levels.

At the same time, the introduction of the next battery cell generation is also provided in the new, scalable and more efficient vehicle batteries. These should also be flexibly used thanks to the modular modular solution in the respective vehicle architecture. “This increases our flexibility sustainable,” says Juraske. In the future, BMW “decide at short notice, which models in which mix should be equipped with a full electric drive, plug-in hybrid or an internal combustion engine”. “So we can also partial or fully electrify each model according to market demand. Thus, we have created the conditions to bring pure battery vehicles into the width in the future, “explains the developer. His Munich plant builds BMW already around.

A supply risk to the battery cells can not be found at BMW even with increasing demand, as the company has secured the supply via long-term contracts. In addition, BMW has built “in-house skills to the battery cell”, in several cooperation projects with international partners along the value chain to secure technology access and supply. At the same time, the car manufacturers are gradually reducing the proportion of critical raw materials: “For example, the significant reduction in the cobalt share in the battery cell is a key objective of our research and development activities. Another example in our fifth generation electric powertrain is the e-machine that works without rare earths, “explains Juraskeek.

Currently and also for the coming years, however, BMW shows “no competitive advantage in the production of the cell”. These smallest basic units for an electric car battery should therefore continue to be purchased from Asian manufacturers.

Second-life and battery recycling is also a topic at BMW

When working with Northvolt and Umicore it is about building a “closed life cycle for sustainable battery cells in Europe”. Begin with a cell design that allows recycling and continues to use a production process in which predominantly renewable energies are used. The ideal battery life looks like this for Juraskeek: “First, the battery cells should do their service as long as possible in the vehicle. If you are no longer used there, you may be used in a stationary memory. Finally, the battery cells are then recycled and the raw materials reused. So then the circulation closes.”

For BMW, “the use of used batteries as stationary power storage is a consistent step to holistic sustainability“, which will “gain enormous importance” in the context of the energy transition “. A stationary storage can be recorded in times of overwhelming electricity from renewable energies. In times of too low electricity offering, the memory in turn can contribute electricity.

Such network stabilization through the use of used batteries from BMW I3 and MINI e-prototypes have already successfully implemented in development cooperations, for example, with Vattenfall and Bosch or Nexttera, “says Juraskeek. The storage farm in the BMW plant Leipzig with 700 BMW i3 batteries, for example, make it possible to use profitably after use in the vehicle in a second lifecycle in a sustainable energy-economic business model. Thus, the car manufacturer wants to prove that its sustainability idea is far beyond the vehicle.

  1. “Theme sustainability is enough” far beyond the vehicle “

    What a crap. As if that would be different at the burner!!! Again, it is not that the diesel or the gasoline would just be so endless from the dispenser. The energy expenditure for the promotion of oil, refinery, transport etc usually does not expect it. Only the refinery of gasoline from crude oil is used per liter of gasoline 2 kWh electricity …..
