Monitoring System for Battery Stacks

A key parameter for people buying electric vehicles is the performance of the battery in terms of power and durability. During the charge and discharge cycle, a battery cell constantly changes its volume and temperature, it “breathes”. Excessive changes in these parameters lead to degradation and reduced battery lifetime. BaMoS uses ultra-thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used by R&D teams to extend battery lifetime by up to 40%. BaMoS prototype shows in real-dimension and real-time the measurement of pressure distributions inside the battery of an EV.
