BMS uses printed sensors to capture data and extend EV range

InnovationLab now offers BaMoS, its innovative battery monitoring solution (BMS) for automotive applications. It employs ultra-thin printed pressure and temperature sensors to capture detailed battery data down to each cell level, which can be utilised to extend battery lifetime by up to 40%.

With BaMoS, the company now offers a system that captures detailed cell-level pressure and temperature data acquired from ultra-thin printed sensor foils placed between individual battery cells. As battery cells expand and contract throughout the charge-discharge cycle, a pressure-sensitive foil can monitor this 'breathing' to measure the state of charge, detect any irregular behaviour, and eliminate overcharging.

This cell-level information delivers valuable insights into the state of health and performance, helping R&D teams to improve their battery designs and battery monitoring solutions – including extending the range for EVs. The data is spatially and temporally resolved to deliver an accurate picture of battery behaviour.

"Measurement is the first step that leads to improved control and battery performance," said Luat Nguyen, Managing Director at InnovationLab. "Our flexible, ultra-thin printed sensors provide the detailed, accurate data that is necessary to improve the performance and lifetime of batteries for electric vehicles."

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 customer needs.
