Vehicle Charging Control for Power Source Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging of a power storage device in a vehicle using electric power from another vehicle can be prolonged due to conventional charging settings, which are not optimized for rapid charging when power is running low.
Innovation Solution
A vehicle equipped with a power storage device, a charger, and a control device that determines whether an external power supply is from a system power supply or another vehicle, allowing for a change in charging settings to a default or second setting for faster charging when power is from another vehicle, utilizing distinct signals or resistance values to differentiate between power sources.

Engineering Contradiction Analysis
1Productivity
If charging settings are optimized for system power supply (first setting), then charging efficiency from system power supply is improved, but charging time from another vehicle becomes prolonged
Solution Approach 1:
The charging setting is made dynamic by automatically switching between first setting (for system power supply) and second setting (for another vehicle) based on the detected power source type. The control device changes the charging setting in real-time according to the external power source being used, optimizing charging parameters for each specific scenario.
Solution Approach 2:
The invention changes charging parameters (current value, charging start time, etc.) based on the power source type. When another vehicle is detected as the power source, the system switches to second setting with different parameters (higher current value) to reduce charging time, whereas system power supply uses first setting with optimized parameters for efficiency.
2Speed
If charging settings are changed to reduce charging time from another vehicle, then charging speed is improved, but charging efficiency from system power supply deteriorates
Solution Approach 1:
The charging setting is dynamically adjusted based on the detected power source. The control device switches between first setting (optimized for system power supply efficiency) and second setting (optimized for fast charging from another vehicle), ensuring optimal performance for each scenario without compromise.
Solution Approach 2:
The system uses feedback from the control device to detect which power source is connected (system power supply or another vehicle) and automatically adjusts the charging setting accordingly. This closed-loop control ensures the appropriate charging parameters are applied based on real-time conditions.
3Stability of the object's composition
If charging settings are maintained for system power supply, then charging stability is improved, but adaptability to different power sources deteriorates
Solution Approach 1:
The charging system is designed to be universal by accepting both system power supply and another vehicle as power sources. The control device detects the power source type and automatically selects the appropriate charging setting (first or second setting), making the system adaptable to different scenarios while maintaining stable operation.
Solution Approach 2:
The charging setting transitions from a fixed configuration to a dynamic one that adapts to different power sources. The system maintains stability through automated detection and switching between predefined settings, ensuring reliable operation whether powered by system power supply or another vehicle.

AI summary
When the external power supply is connected to the connector, the control device determines whether the external power supply is a system power supply or another vehicle, and when the external power supply is the other vehicle, the control device executes a change process of changing a charging setting from a first setting for charging the power storage device using electric power from the system power supply to a default setting or a second setting for charging the power storage device using electric power from the other vehicle, and then executes charging control in which the charger is controlled such that the power storage device is charged, in accordance with the charging setting.
