A method for diagnosing lithium plating in lithium ion batteries includes performing electrochemical impedance spectroscopy analysis on complete or undisassembled lithium-ion batteries under different temperatures.

Method for diagnosing lithium plating in lithium ion batteries by using electrochemical impedance spectroscopy

In a method for estimating a voltage of a battery a given battery model (BM) is provided, wherein the given battery model (BM) is a single particle model. A C-rate of the battery is determined. The battery model (BM) is adapted based on the C-rate. The voltage of the battery is estimated by means of the adapted battery model (BM).

Method and device for estimating a voltage of a battery

A heatable battery includes a battery cell with an anode, a cathode, an anode connection which is connected to the anode, and a cathode connection which is connected to the cathode. The battery cell has a heating element and a connection for applying a voltage potential to the heating element. The heating element is connected to one of the components of the anode connection and the cathode connection. The battery cell further has a controllable switch which is arranged between the connection for applying the voltage potential to the heating element and the other of the components of the anode connection and the cathode connection.
