Appl. No.:

13/224715

Inventors:

Ilya Kaminsky - El Cajon CA, US
Robert J. Ferran - San Diego CA, US

Assignee:

Electro-Mariner Corp. - San Diego CA

International Classification:

H02K 16/04

US Classification:

310198, 310 71, 310112

Abstract:

A brushless DC motor has at least three stator sections and a single rotor rotating with the three stator sections. Each stator section is wound with three parallel windings having respective three nodes. Each stator section has nine terminals providing independent access to each node so that separate voltages and currents are applied to each parallel winding in the stator section. Thus, the current applied to each stator section is divided substantially equally among the three parallel windings, thereby reducing the current in each winding for the same power requirement for the motor, which reduces the IR losses in the windings and the supply wiring and reduces the power handling requirements in the electronic switches providing the supply voltages. The three parallel windings are connected to external terminals of the motor to form either a delta winding configuration or a wye (star) winding configuration.

Ilya Kaminsky - El Cajon CA, US

International Classification:

H02J 7/00
G01R 31/3835

Abstract:

In one aspect, an embodiment of this invention comprises an energy storage device balancing apparatus. The energy storage device balancing apparatus comprises a balancing circuit and an alarm circuit. Both the balancing circuit and the alarm circuit are coupled to the energy storage device. The balancing circuit is configured to monitor a voltage of the energy storage cell and dissipate energy from the energy storage cell if the voltage is at or above a first reference voltage. The alarm circuit is configured to generate an alarm when the voltage of the energy storage cell is at or above a second reference voltage and dissipate energy from the energy storage cell when the voltage is at or above the second reference voltage.

International Classification:

H02J 7/00

Abstract:

Disclosed are systems and methods for improved cell-balancing circuits, back-up failure detection circuits and alarm extension for cells and modules of an energy storage system. One aspect of the invention comprises an energy storage device cell balancing apparatus. The apparatus comprises a first and a second dissipative component connected in series. The first dissipative component and the second dissipative component are coupled to an energy storage cell. The second dissipative component monitors a voltage of the energy storage cell and, if the voltage is at or above a reference voltage, the second dissipative component conducts a discharging current through the first and second dissipative components. The first dissipative component maintains a voltage drop across the first dissipative component that is proportional to the voltage of the energy storage cell. The second dissipative component maintains a constant voltage drop across the second dissipative component when conducting the discharging current.
