Patent number: 9694697Abstract: A method of balancing current in a vehicle electric system having a system bus, a first battery, a first bi-directional battery voltage converter selectively transferring a first current between the first battery and the system bus, a second battery, a second bi-directional battery voltage converter selectively transferring a second current between the second battery and the system bus, and a controller controlling the first bi-directional battery voltage converter and the second bi-directional battery voltage converter. The method includes sensing the first current and sensing the second current. The first bi-directional battery voltage converter and the second bi-directional battery voltage converter are controlled so that the first current and the second current are equal portions of a load current supplied to an electrical load connected to the system bus.Type: GrantFiled: August 21, 2013Date of Patent: July 4, 2017Assignee: THERMO KING CORPORATIONInventor: Ladislaus Joseph Brabec

Patent number: 9199543Abstract: A method of charging batteries in a vehicle electrical system having a system bus, a first switch selectively connecting a first battery with the system bus, a second switch selectively connecting a second battery with the system bus, and a controller monitoring a voltage of the vehicle electrical system and controllably opening and closing the first switch and the second switch. The method includes closing the first switch and opening the first switch if the voltage of the vehicle electrical system traverses a threshold value. The method also includes closing the second switch and opening the second switch if the voltage of the vehicle electrical system traverses the threshold value.Type: GrantFiled: July 29, 2010Date of Patent: December 1, 2015Assignee: THERMO KING CORPORATIONInventor: Ladislaus Joseph Brabec

Patent number: 9102241Abstract: A battery module for use with a vehicle electrical system. The battery module includes a bi-directional battery voltage converter, a first battery, and a second battery. A first relay selectively connects the first battery to the bi-directional battery voltage converter. A second relay selectively connecting the second battery to the bi-directional battery voltage converter. A controller selectively energizes the first relay, selectively energizes the second relay, and controls a direction of current through the bi-directional battery voltage converter.Type: GrantFiled: April 8, 2013Date of Patent: August 11, 2015Assignee: THERMO KING CORPORATIONInventor: Ladislaus Joseph Brabec
