Smart battery charging software in the cloud continually analyze the battery status and take appropriate action to prevent or slow down cell aging. These measures can reduce the wear and tear on the battery, the most expensive component of an electric vehicle, by as much as 20 percent. Real-time data gathered from the vehicle and its surroundings plays a key role here. The cloud services utilize this data to optimize every single recharging process and to provide drivers with tailored driving tips on how to conserve battery power via the dash display. Bosch calls the new service Battery in the Cloud, and its first customer is DiDi, China’s leading provider of mobility services.
“Bosch is connecting electric-vehicle batteries with the cloud. Its data-based services mean we can substantially improve batteries’ performance and extend their service life,” says Dr. Markus Heyn, member of the board of management of Robert Bosch.
The average service life of today’s lithium-ion batteries is 8-10 years or between 500 and 1,000 charge cycles and battery makers usually guarantee mileage of between 100,000 and 160,000 kilometers. However rapid battery charging, high numbers of charge cycles, an overly sporty driving style, and extremely high or low ambient temperatures are all sources of stress for batteries, which makes them age faster.
The cloud-based services are designed to recognize, and counter, these stresses. All the battery data such as current ambient temperature and charging habits is transmitted in real time to the cloud, where machine-learning algorithms evaluate the data. This provides a window into the battery’s current status at all times, but enabling a reliable forecast of a battery’s remaining service life and performance to be made for the first time. Previously, it was not possible to make any accurate forecast of how quickly an electric-vehicle battery would wear out.
