“Powerful batteries with long services lives will make electromobility more viable,” said Heyn. Another feature of the smart software battery charging functions is the use of the swarm principle: the algorithms used for analysis evaluate data gathered from an entire fleet, not just from individual vehicles. Swarm intelligence is the key to identifying more of the stress factors for vehicle batteries, and to identifying them more quickly.

The data enables Bosch to actively protect the batteries against aging. To give one example: fully-charged batteries age more quickly at particularly high or low ambient temperatures. So the cloud services ensure that batteries are not charged to 100 percent when conditions are too hot or too cold. By reducing the battery charge by only a few percentage points, the battery is protected against inadvertent wear and tear. Data in the cloud will also help improve battery maintenance and repair. As soon as a battery fault or defect is identified the driver or fleet operator can be notified. This increases the chances that a battery can be repaired before it becomes irrevocably damaged or stops working altogether.

The cloud services also optimize the battery charging process itself. Smart software in the cloud can calculate an individual charge curve for each recharging process, regardless of whether it takes place at home or elsewhere. This means the battery is recharged to the optimum level, helping conserve the cells. While existing apps with charge timers merely allow drivers to time the recharging process so that it is carried out when demand for electricity is low, the software uses a specially developed recharging process as part of the new battery charging services. This optimizes both fast and slow charging and control electricity and voltage levels during the recharging process, prolonging battery life.

Up to now, different battery charging processes have been programmed into electric vehicles. Going forward, Bosch will offer automakers innovative recharging strategies that complement the processes available. When, for example, drivers want to recharge their batteries faster, a rapid recharge process automatically shortens the time required without damaging the battery. Another strategy optimizes the more leisurely standard recharging process, which can take several hours.
