Cloud-based swarm intelligence helps batteries maintain performance for longer

• Markus Heyn: “Bosch is connecting electric-vehicle batteries with the cloud, and substantially improving performance and service life.”
• Smart algorithms recognize battery stress factors and optimize the recharging process.
• Mobility services provider DiDi is the first company to use the Bosch battery services.

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. 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. Smart software functions 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. 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.
