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 device is provided for determining the internal temperature of an electrochemical energy storage device, particularly for a motor vehicle. The internal temperature of a cell winding of the energy storage device is determined by calculation in a control device of the energy storage device by way of a thermal model for the energy storage device which is saved in the control device.
