Abstract:
Embedding impedance spectroscopy into onboard applications such as electric vehicles increases the diagnostic capabilities of battery management systems largely. A novel approach is presented and experimentally investigated throughout this work, whereby the load current excitation injected by the electric powertrain is pulsed by transistors. With a reconfigurable battery system, this form of active impedance spectroscopy can be used without further hardware. To obtain high-quality impedance data...     »
