EV Rescue Server Selecting Power-Supplying Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles with low state of charge may be unable to reach the nearest charging station, making it impossible to charge their power storage devices without traveling to a charging location.
Innovation Solution
A movable body rescue system where a server communicates with electric vehicles to select a nearby vehicle with sufficient power to supply electricity to a depleted vehicle, allowing it to charge without traveling to a charging station, by transmitting location and power information and selecting the closest capable vehicle to provide power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electric vehicle with low state of charge travels to the nearest charging station, then the vehicle can be charged, but the vehicle may be unable to reach the charging station due to insufficient power
Solution Approach 1:
A server acts as an intermediary between the depleted electric vehicle and potential power-supplying vehicles. The server receives location and power information from multiple vehicles, processes this data, and selects an appropriate power-supplying vehicle to rescue the depleted one, enabling charging without the depleted vehicle needing to reach a charging station
Solution Approach 2:
Instead of the depleted vehicle traveling to obtain power from a charging station, the system inverts the approach by having another vehicle with sufficient power travel to and supply power directly to the depleted vehicle, reversing the traditional charging direction
2Reliability
If any second movable body is selected to supply power, then power can be supplied to the first movable body, but the selected vehicle may be incapable of supplying sufficient power or unable to reach the first vehicle
Solution Approach 1:
The system implements feedback by having each second movable body transmit information about its power supply capability to the server. The server uses this feedback information to evaluate and select only those vehicles that are truly capable of supplying power and reaching the first movable body, ensuring reliable power supply while managing selection complexity through structured information exchange
3Reliability
If a power-supplying vehicle travels to the first movable body to supply power, then the first vehicle can be charged without traveling, but the power-supplying vehicle may not have enough power to return to a charging station after supply
Solution Approach 1:
The server performs preliminary evaluation by receiving and analyzing power information from each second movable body before selecting one for the rescue mission. This preliminary action ensures that the selected vehicle has sufficient power not only to reach the first movable body but also to return to a charging station after power supply, preventing the situation where the rescuer becomes stranded
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the charging of a vehicle's power storage device without the need to travel to a charging station, ensuring timely and efficient power supply while avoiding selection of vehicles incapable of providing power, thus preventing situations where the power-supplying vehicle cannot reach a charging station after supplying power.
Implementation Method 1
a first movable body equipped with a first power storage device storing electric power for traveling
Implementation Method 2
a plurality of second movable bodies each equipped with a second power storage device storing electric power for traveling
Implementation Method 3
the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies
Data Source
AI summary
A depleted EV transmits first information including a current location of the depleted EV to a server. Each of the other vehicles transmits second information including a current location of the vehicle to the server. When the server receives from the depleted EV a help signal requesting power supply from another vehicle to the depleted EV, the server selects, from among the other vehicles, a rescue EV to supply electric power to the depleted EV, using the first information and the second information.
