Complex electrical systems such as battery packs are pushed further to comply with the continuously rising demands for power, energy and safety. This triangle of requirements needs to be optimized in all three directions, but has to be well balanced using as much information about the battery’s parameters, such as temperature. Today’s battery packs lack of gapless temperature acquisition due to a...
Reduced order equivalent circuit battery models are widely used for modeling batteries as a part of complex system or as a basis for battery monitoring algorithms. These models are often parameterized in frequency domain using impedance spectroscopy or in time domain by applying current profile and measuring respective voltage response. This paper shows how the frequency characteristic of a typical...
