Bosch through the cloud extends service life of EV batteries

To help batteries last longer, Bosch is developing new cloud services that supplement the individual vehicles’ battery-management systems. “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 GmbH.

Stress makes cells age faster. Something that geneticists have long since demonstrated for the human body is also true for electric-vehicle battery cells. The older the batteries get, the lower their performance and capacity, and the shorter the range of the vehicle. Smart software functions in the cloud continually analyze the battery status and take appropriate action to prevent or slow down cell aging. As with mobile phones where the top-of-the-range manufacturers with stamina mode and modes like slower charging when software knows that at that time of day the mobile phone stays longer on the charger, Bosch’s software will also have smart battery functions.

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. Didi Chuxing, a globally leading mobility platform based in China, is working with Bosch to introduce Battery in the Cloud across DiDi’s electric vehicle fleet. The aim is to optimize battery performance, thus benefiting both drivers and fleet operators within DiDi’s ecosystem.
