Title: Innovations by Volker Hartmann

Introduction

Volker Hartmann is a notable inventor based in Munich, Germany. He has made significant contributions to the field of hybrid vehicle technology, holding 2 patents that focus on enhancing safety and efficiency in high-voltage systems.

Latest Patents

One of his latest patents is a method and device for monitoring high-voltage connections of a hybrid vehicle. This innovative monitoring device is designed to protect against contact or access to a hybrid vehicle that contains multiple high-voltage components. It features an electronic control unit connected to a low-voltage vehicle electrical system battery. Power actuators are utilized to actuate at least one electric machine, which is connected to a high-voltage battery through a power switch. The high-voltage components are monitored via a looped circuit, which deactivates them if the circuit is broken. Additionally, a sensor sensitive to magnetic field changes is positioned at a removable contact connection of the electric machine or the electronic control unit. This sensor is linked to the looped circuit, and a control component activates a discharge unit to discharge an energy storage device when the contact connection is interrupted.

Another significant patent by Hartmann is a high-voltage plug-connector for motor vehicles. This connector facilitates the detachable electric connection of high-voltage components, particularly for an electric drive system in a motor vehicle. It consists of a plug with electric power contacts and a socket with mating contacts. A signal plug interacts with signal contacts to activate the high voltage. The design includes a mechanical lock that ensures safety by preventing the release of the plug until the electric contact is opened.
