HEV Management Device Prioritizing Fuel Reserves for V2G Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid electric vehicle management systems struggle to select appropriate vehicles for external charging and discharging when multiple vehicles are equipped with internal combustion engines, leading to potential issues such as running out of fuel or electricity, which can affect traveling.
Innovation Solution
A hybrid electric vehicle management device and method that acquires and analyzes vehicle information, including fuel levels and charging capabilities, to prioritize vehicles with larger fuel reserves for external charging and discharging tasks, ensuring they can travel longer distances and generate more power, thus reducing the risk of running out of electricity or fuel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles are selected for external charging based only on whether they are equipped with an internal combustion engine, then vehicles without internal combustion engines can be preferentially caused to perform external charging, but when a plurality of vehicles is equipped with an internal combustion engine, it is not possible to select an appropriate vehicle, which may cause the selected vehicle to run out of electricity or fuel and affect traveling
Solution Approach 1:
The patent changes the selection parameters from a simple binary classification (vehicle type) to a multi-parameter evaluation system that includes remaining fuel amount, remaining electricity amount, and travel distance. This allows for more nuanced and appropriate vehicle selection when multiple vehicles are equipped with internal combustion engines, preventing selected vehicles from running out of energy during travel.
2Productivity
If a vehicle with small fuel reserve is selected for external charging, then more vehicles can be utilized for power grid support, but the vehicle may run out of fuel or electricity during traveling, affecting its functionality
Solution Approach 1:
The patent introduces multiple selection parameters including remaining fuel amount, remaining electricity amount, and travel distance to evaluate vehicle suitability. This multi-parameter approach ensures that vehicles with sufficient energy reserves are selected for external charging, maintaining both power grid support capacity and vehicle traveling reliability.
Data Source
AI summary
A hybrid electric vehicle management device configured to manage a hybrid electric vehicle that includes an internal combustion engine and that is configured to perform either or both of external charging and external discharging, includes a processor. The processor is configured to acquire vehicle information of a first hybrid electric vehicle and vehicle information of a second hybrid electric vehicle. The vehicle information includes information on the amount of fuel remaining in the hybrid electric vehicle. The processor selects, based on the vehicle information, the first hybrid electric vehicle as a hybrid electric vehicle to which either or both of the external charging and the external discharging is to he requested. The amount of fuel remaining in the first hybrid electric vehicle is larger than the amount of fuel remaining in the second hybrid electric vehicle.
