Robert Bosch GmbH says it has developed artificial intelligence software to help electric vehicle batteries last longer.

The cloud-based system continuously monitors various battery metrics, optimizes charging and can provide driving tips to help maximize vehicle range, according to the supplier. China’s DiDi Chuxing plans to offer the technology across its car-sharing network, which includes EVs from more than a dozen carmakers.

As soon as a battery fault or defect is identified, the system will notify the driver or fleet operator for maintenance. Bosch estimates that this can “substantially” improve performance, reduce wear and tear on the battery by as much as 20%, slow the aging process and alert motorists before irrevocably damage occurs.

In addition to scheduling recharging during non-peak grid times, the system controls electricity and voltage levels during the process to help prolong battery life, according to Bosch. The software can calculate an individual charge curve, regardless where the charging is done, to conserve the cells. Bosch notes that current charging systems can cause performance and capacity degradation.

The new cloud-based system uses machine-learning algorithms to evaluate all battery-relevant data, including charging habits and ambient temperatures. Noting that fully charged batteries age more quickly at extreme temperatures, Bosch says the new system will charge batteries to less than 100% capacity when conditions are too hot or too cold.

The system also can apply “swarm” intelligence to gather and analyze data across a vehicle fleet. This can help identify trends and potential stress points, Bosch says.
