BMW showcased the sixth generation of eDrive technology, set to debut in the upcoming Neue Klasse vehicle range. Production of the first Neue Klasse model begins later this year at Plant Debrecen, Hungary.

This next-generation technology focuses on several key advancements:

• Intelligent battery control: The BMW Group-developed Energy Master central control unit, produced at Plant Landshut, intelligently manages the high-voltage battery.
• Revolutionary battery technology: A new high-voltage battery concept, featuring BMW’s cylindrical cell, promises significant improvements in energy density, charging speed and range.
• Flexible electric drive systems: BMW’s technology-neutral approach to electric drive systems allows for the use of different electric motor types (SSM and ASM), providing flexibility and adaptability.
• Modular motor production: A modular approach to electric motor production enables efficient scaling and customisation.
• Integrated expertise: The BMW Group leverages expertise across the entire electric mobility value chain, from development and purchasing to production and recycling, concentrated in Bavaria and Austria.

A technology-open approach to electric mobility

“Electric mobility is the future for the BMW Group and a key area of growth,” says Dr Joachim Post, a member of BMW AG’s management board, purchasing and supplier network. “We are leading the way with this drivetrain technology. Our technology-open approach recognises diverse global mobility needs. We strive to offer customers the best drive concept for every requirement, demonstrating that it’s possible to lead in electric mobility while catering to varied needs.”

Gen6 batteries: Slimmer, faster, longer range

The sixth-generation BMW eDrive technology (Gen6) delivers a quantum leap in performance. Improvements include 30% faster charging speeds and a 30% increase in range, with potential for even greater gains in specific models. Gen6, featuring 800V technology, will debut in the Neue Klasse and subsequently be rolled out across BMW’s electric vehicle range.

The Gen6 battery concept is adaptable to all vehicle segments, including high-performance BMW M models.

The BMW Energy Master: Intelligent control

The BMW Energy Master central control unit manages the high-voltage battery, providing interfaces for high and low-voltage power supply and battery data. It controls power to the electric motor and vehicle electrical system, ensuring safe and intelligent battery operation.

Cell-to-pack and pack-to-open-body manufacturing

Gen6 battery production utilises cell-to-pack and pack-to-open-body principles. Cell-to-pack involves directly placing cylindrical cells into the battery housing, while pack-to-open-body integrates the battery as a structural vehicle component.

Improved performance and efficiency

Compared to a Gen5 xDrive model, a future Neue Klasse model with EESM and ASM technology will see a 40% reduction in energy losses, a 20% cost reduction and a 10% weight reduction. Customers will be able to choose models with one, two, three or four electric motors. Gen6 technology contributes to an overall vehicle efficiency gain of around 20% for the Neue Klasse.

Modular manufacturing

The modular concept for the Gen6 electric drive system enables flexible manufacturing of various variants, leading to economies of scale and cost savings and this puts the BMW Group at the forefront of future vehicle technology.
