Publication number: 20230398881Abstract: A method is provided for operating a bidirectional charger (1) for DC charging of electric vehicles. The charger (10) has a charging terminal (11) for connecting an electrically driven vehicle and at least one power electronics unit (12) for providing defined charging current and defined charging voltage at the charging terminal (11). The power electronics unit (12) is subjected to a self-test voltage of at least the maximum charging voltage of the charger (10) at defined time intervals for a defined time for performing a self-test when there is no vehicle at the charging terminal (11). A check then is performed to ascertain whether a short circuit or defect is formed at the power electronics unit (12). The charging terminal (11) is enabled for charging a vehicle if no short circuit is found and the charging terminal is blocked for charging a vehicle when a short circuit is established.Type: ApplicationFiled: June 9, 2023Publication date: December 14, 2023Inventors: Raoul Heyne, Holger Ochs, Daniel Ziegler, Thorsten Ochs, Simon Bareiss

Patent number: 8794046Abstract: Self-diagnosis of a particle sensor may be used for determining a particle content in a gaseous stream. The particle sensor may include at least two interlocking, interdigital electrodes and a heating element. The heating element may be separated from the electrodes by an insulation layer. The particle sensor may be heated in a regeneration phase and a soot load on the particle sensor can thereby be removed. A semiconductive layer may be formed in the insulation layer directly beneath the electrodes by means of external doping or auto-doping. To perform a self-diagnosis, a measurement voltage may be applied at least periodically between the electrodes and a self-diagnostic current may be measured.Type: GrantFiled: August 5, 2010Date of Patent: August 5, 2014Assignee: Robert Bosch GmbHInventors: Sabine Roesch, Benjamin Gaertner, Johannes Grabis, Alexander Hetznecker, Thorsten Ochs, Henrik Schittenhelm

Publication number: 20090314060Abstract: The invention relates to a circuit assembly for operating a sensor array, in particular, a gas sensor array for detecting gases, which comprises at least one signal line. According to said invention, a signal line is divided into two parallel line branches with a sensor and a diode, preferably a Schottky diode, arranged in each of said two parallel line branches, whereby the two diodes have opposite electrical polarity. The use of different polarity diodes permits actuation of both sensors through only one signal line. It can be determined if the current flows through one or the other of both sensors by merely polarizing the electrical potential applied to the signal line appropriately.Type: ApplicationFiled: May 2, 2006Publication date: December 24, 2009Applicant: Robert Bosch GmbHInventors: Siegbert Steinlechner, Bernd Schumann, Thorsten Ochs, Bernhard Kamp
