Abstract
A motor vehicle and method for analyzing the condition of a traction battery of a motor vehicle, wherein the motor vehicle includes an electric or hybrid propulsion system with an electric motor for driving the motor vehicle, power electronics for driving the electric motor, a battery management system with a monitoring device for monitoring the traction battery, and the traction battery. Impedance spectroscopy is performed on the traction battery with an alternating current across multiple alternating current frequencies. At least one battery parameter of the traction battery is determined based on the impedance spectroscopy performed. In the context of impedance spectroscopy, the traction battery is supplied with alternating current at several alternating current frequencies by the power electronics.
