Printed sensors provide temperature and pressure data for EVs
Temperature and pressure data provided by printed sensors developed by InnovationLab, gives new insight into battery behaviour and performance for electric vehicles (EVs), says the company.
BaMoS is the battery monitoring technology for automotive applications. BaMoS uses thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used to extend battery lifetime by up to 40 per cent.
While the battery is the most important component in an EV, not much is known about how a battery system reacts to stress tests in terms of temperature and pressure. Equally unknown is what happens during the charging cycle, because data from inside a battery system is usually not easily accessible.
BaMoS captures detailed, cell-level pressure and temperature data, obtained from the thin printed sensor foils which can be placed between individual battery cells. As battery cells expand and contract during the charge-discharge cycle, the pressure-sensitive foil can monitor this “breathing”, to measure the state of charge, detect any irregular behaviour, and prevent overcharging.
This cell-level information delivers valuable insights into state of health and performance, helping R&D teams to improve their battery designs and battery monitoring solutions, advised InnovatioLab, including extending range for EVs. The data is spatially and temporally resolved to provide an accurate picture of battery behaviour.
InnovationLab offers a complete battery monitoring solution, including the sensor foils, electronics to gather and process the captured data and software for live visualisation, storage and analysis of the data. Both the pressure and temperature sensors can be customised in terms of size, resolution and substrate material to meet the particular needs of a customer.
Founded in 2008, InnovationLab provides printed electronics, with a focus on flexible pressure sensors, as well as temperature, moisture and gas sensors and the capability to design and produce fully integrated hardware / software systems. The company offers customised solutions and supports high-volume production at two manufacturing sites in Germany. It provides hands-on support to its customers throughout the entire product value chain, from concept to bulk production of printed functional products.
InnovationLab provides expertise in materials, processes and printing technologies and supports numerous research and industrial partners at its lab and fabrication facility.
