RECHARGABLE ENERGY STORAGE SYSTEM BALANCING - A simplified explanation of the abstract
This abstract first appeared for US patent application 17839691 titled 'RECHARGABLE ENERGY STORAGE SYSTEM BALANCING
Simplified Explanation
The abstract describes a method and apparatus for transferring electrical energy between a pair of series connected batteries and a power inverter connected to a motor's stator winding. The power inverter operates as a switched-mode power converter to charge and discharge the stator phase windings using the batteries.
- The method involves connecting a midpoint of the series connected batteries to the motor's stator winding.
- The power inverter is controlled to function as a switched-mode power converter.
- The power inverter charges one of the stator phase windings from one battery and discharges it to the other battery.
Potential Applications:
- This technology can be applied in electric vehicles to efficiently transfer electrical energy between batteries and the motor.
- It can be used in renewable energy systems to optimize energy storage and utilization.
Problems Solved:
- The technology solves the problem of efficiently transferring electrical energy between batteries and a motor's stator winding.
- It addresses the challenge of managing power flow in systems with series connected batteries.
Benefits:
- The method and apparatus enable efficient charging and discharging of stator phase windings, improving overall energy utilization.
- It allows for better control and management of power flow in systems with series connected batteries.
- The technology can contribute to increased efficiency and performance in electric vehicles and renewable energy systems.
Original Abstract Submitted
A method and apparatus for electrical energy transfer between a pair of series connected batteries coupled between positive and negative DC rails of a power inverter operatively connected to a plurality of stator phase windings of a stator winding of a motor may include coupling a midpoint of the pair of series connected batteries to the stator winding of the motor, and controlling the power inverter to operate the power inverter and the stator winding as a switched-mode power converter to charge at least one of the stator phase windings from one of the pair of series connected batteries and to discharge the at least one of the stator phase windings to the other of the pair of series connected batteries.
