Abstract: An energy storage unit for an electrical consumer includes at least one energy storage cell, a first printed circuit board for electrically contacting the at least one energy storage cell having a first and a second power supply contact of the energy storage unit. The first printed circuit board is arranged adjacent to the at least one energy storage cell and comprises at least one temperature sensor for sensing a temperature of the at least one energy storage cell. At least one further printed circuit board is electromechanically connected to the first printed circuit board and the at least one temperature sensor is arranged on the at least one further printed circuit board. The energy storage unit can be used with an electrical consumer such as a hand-held power tool with the energy storage unit designed as a removeable battery pack.

Abstract: A temperature sensor device for a battery pack. The temperature sensor device has an electronics unit including a circuit board, at least one temperature sensor which is connected to the electronics unit, the temperature sensor being connected to the electronics unit with the aid of a carrier element, the carrier element being fastened at a first fastening point and at a second fastening point on the circuit board, and the at least one temperature sensor is situated in the region of the second fastening point. A positioning element is placed between the circuit board and the carrier element in the region of the second fastening point, which is developed for positioning the at least one temperature sensor.
