Patent number: 9853465Abstract: A circuit and a method for connecting a first electrical storage device and a second electrical storage device in parallel is disclosed. The first electrical storage device and the second electrical storage device have in each case a no-load voltage UBat1, UBat2 and an impedance R1 and R2, respectively, and have connecting terminals for charge withdrawal or charge supply. The no-load voltage UBat1 of the first storage device is greater than the no-load voltage UBat2 of the second storage device. In the case of a charge withdrawal, a charge is initially only withdrawn from the first storage device and the second storage device is connected in parallel with the first storage device when the difference of the voltage dropped across the connecting terminals of the first storage device and the no-load voltage UBat2 of the second storage device is less than a predetermined differential add-on voltage.Type: GrantFiled: February 22, 2012Date of Patent: December 26, 2017Assignee: Torqeedo GmbHInventors: Jens Biebach, Friedrich Boebel

Patent number: 7659699Abstract: A battery with at least one battery cell has two battery poles and current-conducting connections between the battery cells and the battery poles. A safety switching encompasses a current-limiting element in the connection between the battery cells and one of the battery poles. A switch is parallel to the current-limiting element and a control device closes the switch, if the current between the battery cells and the battery poles falls below a predetermined threshold minimum current.Type: GrantFiled: January 22, 2007Date of Patent: February 9, 2010Assignee: Torqeedo GmbHInventor: Friedrich Boebel

Patent number: 7614925Abstract: A transportable outboard drive for a boat has a head, a pylon, a shaft connecting the head and the pylon, an electric motor and a cable running inside the shaft. The shaft has at least two shaft sections and wherein the head, shaft and pylon can be arranged in a working configuration or in a transport configuration. In the working configuration, the head, the shaft and the pylon are rigidly connected to each other. In the working configuration and the transport configuration, the cable and shaft are differently positioned with respect to each other, whereas, in its transport configuration, the shaft sections are separated from each other.Type: GrantFiled: August 29, 2006Date of Patent: November 10, 2009Assignee: Torqeedo GmbHInventors: Friedrich Boebel, Klaus Kraft, Heinrich Walk

Publication number: 20070046131Abstract: A boat drive has a permanent magnet-excited, electronically commutated synchronous motor with a stator and a rotor. The number of poles of the stator and the number of poles of the rotor are different. The magnetic field created between the poles of the stator and the poles of the rotor is an essentially radial field with respect to the shaft of the rotor. The poles of the rotor have a greater distance from the shaft of said rotor than the poles of the stator.Type: ApplicationFiled: August 29, 2006Publication date: March 1, 2007Applicant: Torqeedo GmbHInventors: Friedrich Boebel, Klaus Kraft, Heinrich Walk
