Power Supply Device Switching Vehicles for Continuous Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply devices for storage-battery-equipped vehicles cannot continuously supply electricity to a load as they lack the ability to switch power sources, leading to inefficient energy distribution and potential battery deterioration.
Innovation Solution
A power supply device with vehicle connecting portions, a load connecting portion, a power supply portion, a memory portion, and a supply control portion that selects a storage-battery-equipped vehicle as a power source based on State of Charge (SOC), charge/discharge history, and temperature conditions to ensure continuous electricity supply while preventing battery deterioration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single storage-battery-equipped vehicle is used as a power source, then the device structure is simple, but the load cannot be continuously supplied with electricity when the battery is depleted
Solution Approach 1:
The system divides the power supply function across multiple storage-battery-equipped vehicles, with each vehicle independently capable of serving as a power source. The control device segments the power supply task by selecting different vehicles as supply vehicles based on their battery states, enabling continuous power supply while maintaining individual vehicle simplicity.
Solution Approach 2:
Each storage-battery-equipped vehicle is designed with dual functionality: it can operate as a load-receiving vehicle when needing power and as a supply vehicle when having excess power. This multi-functionality allows any vehicle to potentially serve as a power source, eliminating the need for dedicated generator vehicles and enabling flexible power supply switching.
2Duration of action of moving object
If the storage battery is continuously charged and discharged, then the electricity supply duration is extended, but the storage battery deteriorates faster
Solution Approach 1:
The control device continuously monitors the charge/discharge cycle count for each storage battery and uses this feedback information to make intelligent switching decisions. When a battery reaches a predetermined cycle threshold, the system switches to another vehicle as the supply vehicle, preventing excessive battery deterioration while maintaining continuous power supply capability.
Solution Approach 2:
The system dynamically adjusts the power supply configuration by switching between different supply vehicles based on real-time battery conditions. This dynamic switching allows the system to optimize between electricity supply duration and battery life, extending the overall system operational life by distributing charge/discharge cycles across multiple batteries.
3Reliability
If power supply switching between multiple vehicles is implemented, then continuous electricity supply is achieved, but the control complexity increases
Solution Approach 1:
Each storage-battery-equipped vehicle is equipped with self-diagnosis capability that automatically reports its battery state (charge level, temperature, cycle count) to the control device. This self-service approach eliminates the need for complex manual monitoring and simplifies the control device's task to primarily processing incoming status information and making switching decisions based on predetermined criteria.
4Ease of manufacture
If the storage battery is used as a power source, then external fuel is not required, but the power supply is limited by battery capacity and charge/discharge cycles
Solution Approach 1:
The system merges the power supply capabilities of multiple storage-battery-equipped vehicles into a unified power network. By combining the energy reserves of multiple batteries and enabling switching between them, the system effectively extends the total power supply duration beyond what a single battery could provide, while maintaining the environmental benefits of electric power storage.

AI summary
A power supply device including vehicle connecting portions, a load connecting portion, a power supply portion, a memory portion for storing the number of charges and discharges for each storage-battery-equipped vehicle, and a supply control portion for performing control such that the power supply portion performs a discharge operation only on a selected supply vehicle. The supply control portion selects as the supply vehicle one of the storage-battery-equipped vehicles that satisfies a first condition that an SOC of a storage battery is greater than or equal to a prescribed value and a second condition that the number of charges and discharges is not the highest among the storage-battery-equipped vehicles.
