Automakers can use monitoring software to collect data from the BMS. Analyzing the data gives automakers insights into which lithium ion battery packs or cells are performing better than others and safety information about the condition and performance of the battery under different pressures.
The information gathered from software also gives battery pack manufacturers, fleet managers and other stakeholders a chance to work on extending battery life by identifying deviations from expected performance levels.
Few companies are in the business of making software that analyzes data from battery management systems. Among them are Ion Energy and Berkeley, Calif.-based Voltaiq.
Ion Energy's customers include Tata Motors and aerospace giant Airbus.
In September, Ion Energy launched Edison Analytics, a software platform that ingests and analyzes battery data to identify patterns, predict life degradation, provide prognostic alerts and send over-the-air updates on the battery's performance.
Ion says its software product measures cell voltages, ensuring balanced charge cycles. It also identifies the battery's state of charge and controls crucial safety systems.
Ion Energy's analytics software, which is cloud-based, also allows customers to examine data from batteries that have already been installed in vehicles.
"We believe that the next 10 to 15 years are a huge opportunity in the energy storage and consumption side of things," Aryan said. "As these EVs make it to the roads, the charging infrastructure is skewing consumption patterns, and new consumption patterns are emerging."
Edison Analytics' software platform goes hand in hand with Ion's battery management system, as the products can be used individually or together, depending on the customer's needs.
Ion says a handful of major automakers are testing the platform. The company is already a supplier to battery manufacturers and startup automakers in 12 countries. Aryan said the platform was used in 20,000 vehicles in 2018 and is expected to be in 100,000 vehicles by early 2020.
