EV Charging Switch Network for Dynamic Charger Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing motor vehicle charging infrastructure is inflexible and inefficient, leading to issues such as occupied charging stations being unavailable and unoccupied stations being unused, particularly for alternative energy vehicles, which do not justify the installation of multiple charging systems due to low vehicle density and varying charging needs.
Innovation Solution
A system with two chargers of different charging characteristics, each connected to multiple locations via an electric chain, using a switching system controlled by a computerized system to optimize charger allocation based on demand information, ensuring efficient use of charging capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple charging systems are installed at each station to serve different energy types, then the charging service coverage is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent applies universality by designing a single charging station that can serve multiple energy types (fossil fuels and alternative energies) through a unified infrastructure. The station accommodates different vehicle types and charging needs without requiring separate dedicated stations for each energy type, thereby reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The patent implements dynamics by making the charging station configuration adaptable and reconfigurable. The station can dynamically adjust its services based on the mix of vehicles present, allowing it to optimize resource allocation between different energy types rather than being fixed to a specific configuration.
2Reliability
If charging stations are reserved exclusively for alternative energy vehicles, then charging availability for these vehicles is improved, but the loss of time for traditional vehicles increases and flexibility decreases
Solution Approach 1:
The patent applies dynamics by creating a dynamic allocation system where charging resources are not permanently reserved but are instead allocated based on real-time vehicle mix and demand. This allows the system to adapt to changing conditions and serve both traditional and alternative energy vehicles efficiently without fixed reservations.
Solution Approach 2:
The patent implements preliminary action by pre-establishing a unified charging infrastructure that can accommodate multiple energy types from the outset, rather than creating separate reserved systems. This proactive design prevents future conflicts and time losses by having the capacity already in place for all vehicle types.
3Loss of energy
If few chargers are installed to reduce infrastructure cost, then the loss of substance is reduced, but the productivity decreases due to insufficient charging capacity
Solution Approach 1:
The patent applies universality by designing chargers that can serve multiple purposes and vehicle types simultaneously. A single charging station can handle both fossil fuel vehicles and alternative energy vehicles, maximizing the utilization of each charger and reducing the total number needed while maintaining adequate charging capacity.
Solution Approach 2:
The patent implements merging by combining multiple charging functions into a single unified station. Instead of having separate dedicated chargers for different energy types, the system merges these functions into one facility that can dynamically serve various vehicle types, thereby reducing infrastructure costs while maintaining productivity.

AI summary
The charging system comprises: two chargers (2a, 2b) which deliver instantaneous electrical energy for charging an electric vehicle, with different electrical charging characteristics, two electrical lines (16a, 16b), each connecting one of the two chargers (2a, 2b) to a plurality of charging points (4), each serving a charging space (5), a switching system (6) which is associated with each charging point (4) and which connects or does not connect an electric vehicle to the first or the second charger (2), such that each charger (2a, 2b) is connected at most to one charging point (4), and a control system (8) which controls the switching system (6).
