Latest Patents

One of Schöffler's latest patents is a method and system for a safety concept for an AC battery. This invention includes a central controller and multiple battery modules, each equipped with a power board featuring various switching states, contactors, current sensors, a fault loop, and a high-speed bus connected to a traction machine. The central controller utilizes a hardware-programmable processor unit with at least one microprocessor core, which runs a control program designed to manage the battery modules, contactors, and fault loop. In the event of an abort fault, the AC battery transitions to a safe operating state, achieved through the emergency disconnection of the central controller.

Another significant patent by Schöffler is a method for measuring current and a corresponding measurement apparatus. This apparatus features a current sensor with at least two channels, which provide measurement signals characterizing the current. The design includes a first channel and a second channel, with the latter capable of measuring a greater maximum current than the former. This innovation enhances the accuracy and reliability of current measurements in various applications.
