Nio and Monolith want to improve EV batteries using AI

The companies will use Monolith’s Anomaly Detector AI software to monitor battery performance data in the field. The results can be compared with test-bench results, essentially giving researchers further insights into battery performance. Moreover, it will help identify abnormalities more quickly by “automating the inspection of raw test data to look for potential errors or abnormalities across hundreds of test channels.”

According to Monolith, “Nio’s battery swap technology presents a unique opportunity to discover new insights into real-world, daily battery usage.” The battery’s condition, performance, and durability will be checked every time it is replaced, enabling continuous monitoring and optimisation. Monolith’s AI algorithm will calculate the relevant data in real-time.

By combining our expertise in battery performance with Monolith’s advanced laboratory capabilities, we’re setting new standards in battery monitoring, ensuring unparalleled efficiency and reinforcing NIO’s dedication to innovation and quality,” said Frank Kindermann, Head of Battery System Europe at Nio.

“Monolith’s deep-learning algorithms allow for automatic detection of battery issues, such as spontaneous discharge and thermal runaway, making it easier to analyse complex real-world data quickly.,” says Richard Ahlfeld, CEO and Founder of Monolith. “This capability not only saves time and resources but also enhances battery safety.”

Moreover, in an interview with Reuters, Ahlfeld further explained that this approach not only opens up possibilities for optimising existing batteries, but also for developing new, more powerful models. “Nio can essentially give you a prototype of a car early on and they keep testing and learning from what you’re doing,” Ahfeld said.

Testing will soon start in five European markets, and Monolith is waiting for the green light from China. Once the regulatory requirements are fulfilled, the startup could work with other carmakers there.

But back to Europe. Reuters says that Monolith already works with “round 10 of the world’s top 20 automakers test electric vehicle batteries using machine learning algorithms, including Mercedes-Benz, BMW and Honda.” The goal is to speed up innovation cycles so that Western car manufacturers can better keep up with their Chinese-based competitors. “They’re obviously way behind China, so they need to learn really, really quickly,” Ahlfeld told the news agency.
