Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for extending the endurance of electric cars by charging or swapping batteries at fixed charging stations are inconvenient and costly, as they require numerous stations and occupy public space, limiting the flexibility and efficiency of battery charging.
Innovation Solution
An energy storage and power supply system is integrated into a vehicle, featuring a switching device, battery detection, speed detection, and a processing unit that controls a power generation device to charge either a main or backup storage battery based on driving or engine speed, allowing for dynamic battery charging and swapping without the need for external stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed charging stations are established to extend electric car endurance, then battery charging convenience is improved, but public space occupation and setting up costs increase
Solution Approach 1:
The petrol car itself becomes a mobile charging station, using its own power generation device to charge the backup storage battery. This self-service approach eliminates the need for external fixed charging stations, thereby reducing public space occupation and setting up costs while maintaining charging convenience.
Solution Approach 2:
The petrol car serves multiple functions: it acts as both a transportation vehicle and a mobile power supply station. The power generation device can charge not only the car's own backup battery but also external electric cars, making the system universally applicable and eliminating the need for dedicated charging infrastructure.
2Ease of operation
If fixed charging stations are established to extend electric car endurance, then battery charging convenience is improved, but the number of charging stations required increases
Solution Approach 1:
The charging system transitions from static fixed stations to a dynamic mobile platform. The petrol car with integrated power generation and storage batteries can move freely, providing charging services at various locations without requiring multiple fixed charging stations to be established.
Solution Approach 2:
Each petrol car equipped with this system becomes an independent mobile charging unit, eliminating the need for centralized fixed charging stations. This distributes the charging function across multiple mobile units, reducing the total number of fixed stations required.
3Use of energy by moving object
If electric cars drive to fixed charging stations to charge batteries, then battery charging is achieved, but time loss and reduced flexibility occur
Solution Approach 1:
The petrol car can charge its own backup battery at any location using its power generation device, eliminating the need to travel to fixed charging stations. This self-charging capability reduces time loss and increases flexibility while maintaining battery charging functionality.
Solution Approach 2:
The backup storage battery is charged in advance during periods when the petrol car is not needed for transportation or when excess power is available. This preliminary charging action ensures power availability without requiring time-consuming trips to charging stations when power is needed.

AI summary
An energy and supply system includes a switching device, a battery detection device, a speed detection device, a processing device, a main storage battery and a backup storage battery. Using the speed detection device, the processing device determines whether the driving speed of the vehicle exceeds a preset speed threshold, or it determines whether the rotation speed of the engine exceeds a preset rotation speed. The processing device uses the battery detection device to determine whether the main battery capacity is greater than the preset capacity. If the processing device determines that the driving speed of the vehicle exceeds a preset speed threshold, or it determines that the rotation speed of the engine exceeds a preset rotation speed, and it determines that the main battery capacity is greater than the preset capacity, the processing device controls the switching device.
