A battery diagnosis apparatus includes a voltage sensor to generate a voltage signal indicating a battery voltage of a battery, a current sensor to generate a current signal indicating a battery current of the battery and a control circuit. The control circuit determines a capacity curve indicating a relationship between the battery voltage and a charge capacity in a set voltage range based on the voltage signal and the current signal collected at each unit time for a constant current charging period. The control circuit determines a differential curve indicating a relationship between the battery voltage and a differential capacity in the set voltage range based on the capacity curve. The control circuit determines an approximate straight line of the differential curve using a linear approximation algorithm, and determines whether lithium deposition is present in the battery based on the approximate straight line.

A battery module for an energy storage arrangement. The battery module has an underside for arrangement on a housing base of a battery housing, an upper side opposite the underside with respect to a first direction, at least one outer side that is different from the underside and the upper side, and at least one liquid sensor by which a liquid can be detected. In doing so, the liquid sensor has a measuring probe which is arranged on the outer side of the battery module and extends downwards in the direction of the underside of the battery module.
