METHOD FOR OPERATING A SWITCHING ARRANGEMENT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18512667 titled 'METHOD FOR OPERATING A SWITCHING ARRANGEMENT

Simplified Explanation

The abstract describes a method for operating a switching arrangement of an energy storage system with multiple battery packs connected to a common traction voltage bus. The method involves identifying a non-connected battery pack, adjusting the current of the common traction voltage bus to reduce the voltage difference, and then connecting the identified battery pack to the common traction voltage bus by closing the associated contactor.

  • Identifying non-connected battery pack:
 - The method involves identifying a battery pack that is not currently connected to the common traction voltage bus.
  • Adjusting current to reduce voltage difference:
 - The current of the common traction voltage bus is adjusted to reduce the voltage difference between the bus and the identified battery pack.
  • Connecting battery pack to common bus:
 - The contactor associated with the identified battery pack is closed to connect it to the common traction voltage bus.

Potential Applications

This technology can be applied in electric vehicles, hybrid vehicles, and renewable energy systems where efficient management of multiple battery packs is required.

Problems Solved

1. Efficient management of multiple battery packs in an energy storage system. 2. Minimizing voltage differences between battery packs and the common traction voltage bus.

Benefits

1. Improved efficiency in utilizing energy from multiple battery packs. 2. Enhanced reliability and performance of the energy storage system. 3. Optimal utilization of battery packs leading to extended lifespan.

Potential Commercial Applications

Optimal battery management systems for electric vehicles, grid energy storage systems, and renewable energy installations.

Possible Prior Art

One possible prior art could be the use of similar switching arrangements in energy storage systems for managing multiple battery packs. However, the specific method described in this patent application may offer unique features or improvements over existing technologies.

Unanswered Questions

How does the method determine the optimal current adjustment for reducing the voltage difference?

The method involves adjusting the current of the common traction voltage bus to reduce the voltage difference, but the specific algorithm or calculation used for determining the optimal current adjustment is not detailed in the abstract.

Are there any safety mechanisms in place to prevent overloading or overheating of the battery packs during the switching process?

The abstract does not mention any safety mechanisms or protocols to ensure the safe operation of the switching arrangement and prevent potential risks such as overloading or overheating of the battery packs.


Original Abstract Submitted

A method for operating a switching arrangement of an energy storage system including a common traction voltage bus and a plurality of parallelly arranged battery packs connectable to the common traction voltage bus is provdied. The switching arrangement comprising an associated contactor for each battery pack, the contactors being configured to connect the battery packs to and from the common traction voltage bus by closing and opening. The method comprises: identifying a non-connected battery pack to be connected to the common traction voltage bus, determining the voltage difference between the common traction voltage bus and the identified battery pack, adjusting the current of the common traction voltage bus to reduce the voltage difference between the common traction voltage bus and the identified battery pack, closing the contactor associated with the identified battery pack to connect the identified battery pack to the common traction voltage bus.
