BMW Takes the Risky Bet of Independence for Its Batteries

BMW is preparing for the future and unveils a concept of electric architecture featuring 800V technology for the Neue Klasse.

While most car manufacturers are turning to specialists like CATL or BYD for their batteries, BMW has chosen to develop its own solution. With the Neue Klasse, the brand promises to redefine standards of electric mobility through advanced technology. This is a common message among all manufacturers, but BMW presents an 800V architecture that promises unprecedented performance. This internally developed solution promises a 30% faster charging time and extended range. The high-voltage batteries use a cylindrical design to increase energy density by 20% compared to the previous generation. This compact design allows for suitable integration into various types of vehicles, including the sportiest models.

The batteries follow a “cell-to-pack” design, where the cylindrical cells are directly integrated into their housing without an intermediate module. They also play a structural role in the vehicles. With energy losses reduced by 40%, a weight reduction of 10%, and costs down by 20%, BMW seems to have found the winning recipe, but a battery is evaluated in action, not on paper.

BMW does not want to delegate

At the heart of this technology is the “BMW Energy Master,” a central unit that manages the energy and data of the battery. Once again designed in-house, it ensures remote software updates, guaranteeing optimal performance under all circumstances.

To reduce its dependence on external suppliers, BMW produces batteries for the Neue Klasse in five new factories located in Europe, China, Mexico, and the United States. This local production model helps mitigate risks related to global disruptions while creating jobs and strengthening local skills.

By committing to develop its own batteries and motors, BMW is taking a bold yet strategic bet. A bet we hope will be successful to bring some hope for an independent and sovereign European automotive industry.
