May 18, 2023
A temperature measurement arrangement for a battery system includes: temperature sensing diodes in a grid and thermally connectable to battery cells of the battery system, a current supply portion, a voltage measurement portion, and a control portion. The grid has first lines and second lines electrically interconnected with the temperature sensing diodes. A forward direction of each temperature sensing diode pointing from the corresponding first line to the corresponding second line. The current supply portion including current supply connections that are, independently of each other, suppliable with electric current. The first lines are connected between the voltage measurement portion and the current supply portion, and the second lines are connected to the control portion. The control portion connects a selected second line to ground, and the temperature measurement arrangement determines a temperature of the corresponding first temperature sensing diodes by measuring voltages via the voltage measurement portion.
