BMW’s Neue Klasse battery technology wins award
Words: Kyle Cassidy
BMW’s next-generation electric vehicle battery has earned a technology award in China, with its combination of new cells, 800-volt architecture and integrated energy management recognised at the World New Energy Vehicle Congress.
The Gen6 high-voltage battery received a “Global New Energy Vehicle Innovative Technology” award at the 2026 event. BMW Group says it was the only car manufacturer from outside China to receive one of the congress’s technology awards.
Gen6 underpins BMW’s Neue Klasse models and is intended to deliver greater range, faster charging and improved efficiency. The sixth-generation eDrive technology will gradually spread across the group’s fully electric line-up.
New cells, fewer layers
At the heart of the battery are new cylindrical cells with high-nickel cathodes. These fit directly into the battery pack, removing the intermediate modules used in other battery designs.
Known as cell-to-pack construction, this approach makes better use of the available space and helps improve energy density at pack level. BMW says the flat battery design also allows closer integration with the vehicle’s architecture.
The entire Gen6 battery range is designed around an 800-volt electrical system and supports bidirectional charging, allowing energy to flow out of the battery as well as into it.
“The Gen6 high-voltage battery represents a technological leap across all customer-relevant features. Its innovative, flat design with cylindrical cells paves the way for greater range and faster charging, while maintaining the highest level of safety,” says Thomas Engelhardt, BMW Group’s Senior Vice President Development High-Voltage Batteries, Charging.
Managing the energy
Another key component is said to be BMW’s Energy Master, a control unit mounted on the battery with hardware and software developed in-house.
It manages energy flow to the drive units and the vehicle’s electrical system, while handling battery data. It also enables compatibility with both 400-volt and 800-volt charging infrastructure.
BMW says the wider system has been designed to accommodate other cell technologies, providing scope for future development.
Safety measures include steel cell housings, integrated cell protection systems, multiple layers of insulation and comprehensive thermal and energy management.
Rather than developing the battery in isolation, BMW has worked across cell chemistry, pack construction, control systems and vehicle integration. The aim is to improve efficiency, charging, range and driving dynamics together.
The company filed patent applications covering more than 500 innovations during the transition from fifth- to sixth-generation eDrive technology.
This is BMW Group’s fifth consecutive year receiving a technology innovation award at the congress, and its sixth recognition overall.
