BMW has Gen6 eDrive technology on the horizon for the upcoming Neue Klasse.
BMW is set to revolutionize its electric vehicle lineup with the introduction of its sixth-generation eDrive technology (Gen6 eDrive), marking a significant advancement in EV powertrain development. Set to debut in the upcoming Neue Klasse vehicles later this year, the new system promises substantial improvements in range, charging capabilities, and overall efficiency.
Key Technical Innovations
At the heart of Gen6 eDrive is a completely redesigned high-voltage battery system featuring new cylindrical cells. These cells deliver 20% greater energy density compared to the previous generation’s prismatic cells. The system incorporates innovative “cell-to-pack” technology, where cells are directly integrated into the battery housing without intermediate modules, optimizing space and efficiency.
The system operates on an 800V architecture, enabling significantly faster charging speeds. BMW claims a 30% improvement in charging time alongside a 30% increase in range, with some models potentially exceeding these figures. Additionally, all Gen6 eDrive-equipped vehicles will feature standard bidirectional charging capability.
Advanced Power Management
A standout feature is the BMW Energy Master, an intelligent central control unit developed in-house. This sophisticated component manages both high and low-voltage power supply while controlling the electric motor and vehicle electrical system. Its integrated hardware and software architecture enables real-time updates through Remote Software Upgrades, enhancing long-term functionality.
Dual Motor Technology
Gen6 introduces a technology-open approach to electric motors, utilizing two distinct types:
- An electrically excited synchronous motor (EESM) with enhanced efficiency
- An asynchronous motor (ASM) for models equipped with BMW xDrive
The EESM features windings fed with direct current instead of permanent magnets, allowing optimal adjustment of the rotor’s magnetic field based on driving conditions. This results in improved efficiency and consistent power output at high speeds. The more compact ASM technology will be primarily used for front-axle applications in all-wheel-drive configurations.
Significant Performance Improvements
Compared to the current Gen5 xDrive models, the new Gen6 system delivers impressive gains:
- 40% reduction in energy losses
- 20% decrease in costs
- 10% weight reduction
- 20% improvement in overall vehicle efficiency
Structural Integration and Manufacturing
The Gen6 eDrive battery system serves as a structural component in the vehicle architecture through “pack-to-open-body” design, contributing to improved vehicle dynamics and space utilization. BMW will manufacture these components across five new production facilities worldwide, following a “local for local” approach to ensure production stability and supply chain resilience.
Thermal Management
The system features sophisticated thermal management, crucial for optimizing range, real-world consumption, acceleration, and charging times. It maintains optimal operating temperatures across the electric motor, power electronics, and high-voltage battery while ensuring passenger comfort.
Future Implementation
The Gen6 eDrive technology will debut in the Neue Klasse vehicles, with production beginning at Plant Debrecen in Hungary. The system’s modular design allows for flexible configuration with one to four electric motors, catering to various performance requirements and market segments.
With these advancements, BMW’s Gen6 eDrive technology represents a significant step forward in electric vehicle development, promising improved performance, efficiency, and user experience for the next generation of BMW electric vehicles. The system’s comprehensive approach to power management, thermal control, and structural integration demonstrates BMW’s commitment to advancing electric mobility while maintaining its reputation for driving excellence.
