MANAGEMENT OF BATTERY CHARGE TO EXTEND BATTERY LIFE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17837265 titled 'MANAGEMENT OF BATTERY CHARGE TO EXTEND BATTERY LIFE

Simplified Explanation

The abstract of this patent application describes a method for managing the charge of a vehicle's battery to avoid peak usage of the electric grid. Here is a simplified explanation of the abstract:

  • The method involves determining the amount of charge needed by the battery at a first time and the remaining amount of charge needed at a second time.
  • Based on these determinations, the charge of the vehicle's battery is preserved within a range of 20% to 80% capacity.
  • The purpose of this preservation is to avoid using the electric grid during peak usage periods.

Potential applications of this technology:

  • Electric vehicles: This method can be applied to electric vehicles to optimize the charging process and reduce strain on the electric grid.
  • Smart grid systems: The technology can be integrated into smart grid systems to manage the charging patterns of multiple vehicles and balance the load on the grid.

Problems solved by this technology:

  • Peak demand on the electric grid: By preserving the charge of the vehicle's battery within a specific range, the technology helps to avoid adding to the peak demand on the electric grid during high usage periods.
  • Battery degradation: By avoiding charging the battery to its maximum capacity, the technology can help extend the lifespan of the battery and reduce degradation.

Benefits of this technology:

  • Grid stability: By managing the charging patterns of electric vehicles, the technology contributes to a more stable and balanced electric grid.
  • Battery longevity: Preserving the charge within a specific range helps to prolong the lifespan of the battery, reducing the need for frequent replacements.
  • Energy efficiency: By avoiding peak usage periods, the technology promotes more efficient use of electricity and reduces strain on the grid.


Original Abstract Submitted

An example operation includes one or more of determining a portion of a needed charge of a battery of a vehicle at a first time; and determining a remaining portion of the needed charge at a second time; preserving a charge of the vehicle's battery to be between around 20% capacity and around 80% capacity, based on the determined portion and the determined remaining portion; wherein the preserving avoids an electric grid's peak usage.
