Patent number: 8922164Abstract: An equipment system includes a battery unit (10) having a monitoring circuit (14), which detects at least one operating parameter of the battery unit (10) and furnishes a control signal, dependent on the operating parameter, for switching means (25, 31). The switching means control the charging and discharging process of the battery unit (10) and are located in the electrical device (20) and in the charger (30), respectively. From the battery unit (10), the control signal is transmitted to the switching means (25, 31) in the electrical device (20) and in the charger (30), respectively. By this provision of shifting the switching means (25, 31) out of the battery unit (10) into the electrical device (20) and into the charger (30), respectively, the heat development in the battery unit (10) and also its structure size are reduced.Type: GrantFiled: February 13, 2012Date of Patent: December 30, 2014Assignee: Robert Bosch GmbHInventors: Arnim Fiebig, Hans-Joachim Baur, Guenther Lohr, Stefan Roepke, Rainer Glauning, Volker Bosch

Patent number: 5099184Abstract: To provide sufficient magnetization to the field of a series motor when the series motor is to be operated in dynamic braking mode, with a dissipating resistor or short circuit element (4) connected across the armature (5), a circuit connection is established between one of the main terminals of the motor through the series field to supply a minimum magnetization current, at least when the motor operates under dynamic braking conditions, typically a few to up to 15% of no-load current of the motor. This is sufficient magnetization so that, even in larger motors where remanent magnetism of the field structure is insufficient, reliable dynamic braking can be ensured. A switch (S; S.sub.1, S.sub.2) selectively connects the motor armature for motor drive or running operation and dynamic braking operation.Type: GrantFiled: November 9, 1989Date of Patent: March 24, 1992Assignee: Robert Bosch GmbHInventors: Friedrich Hornung, Arnim Fiebig, Manfred Kirn, Gunter Schaal

Patent number: 4716304Abstract: For driving each power transistor of a three phase bridge rectifier for utilizing d.c. electric power for the control and energization of a motor, each individual power transistor is provided with an individual driver circuit supplied an individual power supply. Each power transistor in such a rectifier has a reverse voltage free wheeling diode connected between emitter and collector. Each individual driver circuit has its input control signal supplied through a galvanic isolation stage in the form of an optical coupler and the power supply has its input connection to a source of power galvanically isolated by a transformer, supplying a relatively high frequency for powering the rectifier of the driver power supply. The final driver stage utilizes Darlington transistor combinations of complementary types, one Darlington combination being supplied with negative voltage and the other being supplied with positive voltage, by the power supply rectifier.Type: GrantFiled: June 20, 1986Date of Patent: December 29, 1987Assignee: Robert Bosch GmbHInventors: Arnim Fiebig, Rupert Weber
