Parallel Motorcycle Charging Cables to Cut Station Queue Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging electric vehicles, particularly motorcycles, can be time-consuming and lead to queues at charging stations due to infrastructure limitations, necessitating a more efficient use of existing charging infrastructure.
Innovation Solution
A system and method for charging multiple motorcycles simultaneously using parallel charging modules and cables, allowing up to four motorcycles to share a single charging station's electrical flow, with each motorcycle managing its own charging rate to optimize station usage and reduce wait times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If multiple motorcycles charge sequentially at a single charging station, then each motorcycle receives full charging power, but the total charging time and station occupancy time increase significantly
Solution Approach 1:
The patent combines multiple charging circuits into a single charging station, allowing multiple motorcycles to charge simultaneously. The charging station includes a power supply unit connected to multiple charging piles through a distribution system, enabling parallel charging of multiple vehicles without requiring multiple separate charging stations.
Solution Approach 2:
The charging station is designed with multi-functionality to serve multiple motorcycles simultaneously. Each charging pile can independently connect to different motorcycles, and the power supply unit dynamically allocates power to multiple charging circuits, making a single station serve multiple functions and multiple users at once.
2Loss of time
If charging stations are increased to reduce queues, then waiting time decreases, but infrastructure cost and complexity increase
Solution Approach 1:
Instead of building multiple separate charging stations, the patent makes a single charging station universal by equipping it with multiple charging piles and a power distribution system that can simultaneously serve multiple motorcycles. This reduces the number of physical stations needed while maintaining or improving service capacity.
Solution Approach 2:
The charging station is segmented into multiple independent charging piles, each capable of serving one motorcycle. The power supply unit is also segmented into multiple output circuits that can be independently controlled and allocated to different charging piles, allowing modular expansion and efficient resource utilization.
3Duration of action of moving object
If faster charging rates are used, then charging time per motorcycle decreases, but battery degradation increases
Solution Approach 1:
The patent implements dynamic parameter adjustment in the power supply unit, which can change charging current and voltage parameters in real-time based on battery state and requirements. The system monitors charging progress and adjusts parameters to optimize both charging speed and battery health, preventing excessive degradation while maintaining reasonable charging duration.

AI summary
Charging electric vehicles at shared charging stations may involve waiting in line to connect one's vehicle. By allowing multiple motorcycles to charge in parallel at a charging station, better use of the available space can be made and the process can be more efficient for motorcyclists riding in groups. Connectors and cables are configured to connect a chain of motorcycles in parallel to a single charging station. The connectors and cables carry the charging current to each motorcycle and include communication wiring. One motorcycle is deemed a manager motorcycle, which detects the other motorcycles in the chain and initiates charging. Each motorcycle's battery management system controls the amount of charge for its respective battery.
