German engineering and technology company Bosch has announced the development of a method to ensure batteries last longer.
In its 9 July press release, the company detailed the process by which batteries lose performance and capacity as they age. The average life of a lithium-ion battery is between 8-10 years, with makers guaranteeing mileage of between 100,000 and 160,000 km. Stresses such as rapid charging, driving styles, and extreme ambient temperatures can make batteries age faster, however, which Bosch is aiming to counter.
“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,” said Dr. Markus Heyn, member of the board of management of Robert Bosch GmbH.
Using smart, cloud-based software, Bosch said it can supplement vehicles’ built in battery management systems. Measuring battery-relevant data such as ambient temperature and charging habits, Bosch’s machine-learning algorithms evaluate data and take actions to prevent aging. The company said that its methods could reduce wear and tear on batteries by up to 20%.
An example of measures that can be taken was the prevention of 100% charging in especially hot and cold environments. The data collected was also said to help maintenance, notifying the driver if and when faults are identified.
