InnovationLab presents a battery monitoring solution based on organic electronics. With ultra-thin, printed pressure and temperature sensors, users can collect spatially resolved data from individual battery cells. The company promises that this can extend the life of batteries for electric vehicles by up to 40%.
The battery is the most important component of an electric vehicle (EV). Despite extensive research, not much is known about how battery systems react to stress in terms of temperature and pressure and what exactly happens during the charging cycle. This is because data from inside a battery system is not readily available.
With BaMoS, InnovationLab now offers a system for collecting detailed pressure and temperature data at cell level. This information comes from thin printed sensor foils that can be placed between the individual battery cells. As battery cells expand and contract during the charge/discharge cycle, a pressure-sensitive film can monitor this “breathing” to measure the state of charge, detect irregular behaviour and prevent overcharging.
This cell-level information provides valuable insights into battery health and performance. It helps research and development teams improve their battery designs (cell-to-pack design) and battery monitoring solutions – including extending the range of electric vehicles. The data is spatially and temporally resolved to provide an accurate picture of battery behaviour.
“Measurement is the first step that leads to improved control and battery performance,” says Luat Nguyen, managing director at InnovationLab. “Our flexible, ultra-thin printed sensors provide the detailed and accurate data needed to improve electric vehicle battery performance and life.”
InnovationLab (Heidelberg, Germany) offers a complete solution for battery monitoring, including sensor foils, electronics to read and process the collected data, and software to visualise, store and analyse the data. Both the pressure and temperature sensors can be adapted to individual customer requirements in terms of size, resolution and carrier material.
