US 2023/0155188 A1 · DAMAGE DETECTOR FOR A RECHARGEABLE BATTERY

Abstract

In one embodiment, a rechargeable battery, in particular as a power supply device for a power tool, has a rechargeable battery housing, at least one energy storage cell, a controller and a display. The rechargeable battery has a detector for detecting and a display for displaying a mechanical deformation on the rechargeable battery housing. A method for open-loop control and closed-loop control of the rechargeable battery is also provided. The method senses a mechanical deformation using the detection device and emits at least one signal using the detector for displaying the sensed mechanical deformation on the display device.
