ROUTE SEARCH DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240183676 titled 'ROUTE SEARCH DEVICE

Simplified Explanation

The patent application describes a route search device that helps electric vehicles with rechargeable batteries find the most efficient charging stations along their route. Here is a simplified explanation of the abstract:

• Route search unit: Searches for the best route for a vehicle with a rechargeable battery to reach its destination.
• Station search unit: Finds geographically available charging stations along the route and gathers information about the chargers installed in each station.
• Calculation unit: Predicts the future state of the battery at each charging station based on the current battery state and the route.
• Recommended station extraction unit: Selects the best charging station based on the predicted battery state and charger information.

1. 1. 1. Potential Applications

- Electric vehicle navigation systems - Sustainable transportation technology

1. 1. 1. Problems Solved

- Range anxiety for electric vehicle drivers - Efficient utilization of charging stations

1. 1. 1. Benefits

- Increased convenience for electric vehicle owners - Reduced carbon emissions from transportation

1. 1. 1. Potential Commercial Applications
         1. Optimizing Electric Vehicle Charging

- Targeting electric vehicle manufacturers - Collaborating with mapping and navigation companies

1. 1. 1. Possible Prior Art

There are existing electric vehicle navigation systems that provide information about nearby charging stations, but this patent application focuses on predicting battery states and recommending the best charging stations based on that information.

1. 1. 1. Unanswered Questions

1. 1. 1. 1. How accurate are the predicted battery states compared to actual battery performance?

The abstract does not specify the accuracy of the predicted battery states. Further details on the methodology and testing would be needed to determine the reliability of these predictions.

1. 1. 1. 1. What is the criteria used to extract the recommended station from the searched charging stations?

The abstract mentions that the recommended station is selected based on combinations of predicted battery values and charger information, but the specific criteria or algorithm for this selection process is not detailed. Additional information on this decision-making process would be helpful for understanding the device's functionality better.

Original Abstract Submitted

a route search device includes: a route search unit that searches for a route for a vehicle that runs on power of a rechargeable battery to reach a destination; a station search unit that searches for a plurality of charging stations that is geographically available to the vehicle based on the searched route, and acquires output information of chargers installed in each of the charging stations; a calculation unit that calculates, for each of the searched charging stations, a predicted value indicating a future state of the battery when the vehicle reaches the charging station, based on a current state of the battery and a route from a current location of the vehicle to the charging station; and a recommended station extraction unit that extracts a recommended station from the searched charging stations, based on combinations of the predicted values of the battery and the output information of the chargers.
