Patent number: 10978885Abstract: In one aspect, the invention comprises an apparatus for balancing cells in a series string of modules having cells. The apparatus comprises a processing system and a communication circuit. The processing circuit is configured to receive an average cell voltage value from each module. The processing circuit is further configured to determine an overall average cell voltage for all the cells. The processing circuit is also configured to cause each the modules to determine a relative capacitance for each of its cells and cause each of the modules to balance its cells based on the respective relative capacitances. The communication circuit is configured to receive the average cell voltage value from the modules.Type: GrantFiled: January 25, 2018Date of Patent: April 13, 2021Assignee: Maxwell Technologies, Inc.Inventors: Rong Yan, Ulf Carl Mikael Setterberg, Liesel Mathew Chiriyankandath, Christopher James, Magnus Lindbäck, Robert Shaw Lynds

Patent number: 9627908Abstract: This disclosure provides systems, methods and apparatus for a combined battery/capacitor energy storage device. The device includes a first device terminal, a second device terminal, a battery connected between the first terminal and the second terminal, and a capacitor connected in parallel with the battery. In one aspect, a rectifier is connected between the first terminal and the capacitor, the rectifier configured to allow substantially unidirectional current flow from the first terminal to the capacitor. In another aspect, a switch is between the capacitor and the first terminal. In another aspect, a current limiter extends between the first terminal and the capacitor.Type: GrantFiled: March 12, 2013Date of Patent: April 18, 2017Assignee: Maxwell Technologies, Inc.Inventors: Ilya Kaminsky, Robert Shaw Lynds, Mikael Setterberg, Priya Bendale, Ha Q.

Patent number: 9209653Abstract: A device (1) monitors and/or balances an ultracapacitor (3) and/or a module (4) comprising a plurality of ultracapacitors (3) connected in series, the module (4) being connectable in series or in parallel with other modules (4). The device comprises an electronic board (2) comprising digital control and/or command means, such as a microcontroller (5), executing a program for monitoring and balancing the ultracapacitor (3) and/or the module (4). The relative capacitances of the capacitors are measured, and this information is employed to determine when to carry out a controlled discharge of particular capacitors. Temperature information is also employed to determine when to carry out a controlled discharge of particular capacitors. In this way the lifetime of any particular capacitor is, desirably, extended to be no shorter than the lifetime of other longer-lived capacitors in the module.Type: GrantFiled: June 28, 2011Date of Patent: December 8, 2015Assignee: Maxwell Technologies, Inc.Inventors: Xavier Maynard, Andre Milewski, Gianni Sartorelli, Mikael Setterberg
