EV Charging Controller Prioritizes Vehicles by History
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging apparatuses often fail to charge vehicles without specified leaving times, leading to inconvenience and inequity among users, as they prioritize vehicles with scheduled leaving times over those without, potentially leaving vehicles without specified times uncharged.
Innovation Solution
A charging apparatus with multiple charging ports, a controller that determines charging priorities based on charge history information, including connection time and state-of-charge data, to ensure equitable charging among vehicles, using charge-history-dependent and independent patterns to manage charging currents.

Engineering Contradiction Analysis
1Productivity
If preferential-charging control means prioritizes vehicles with scheduled leaving times, then vehicles with scheduled leaving times are charged effectively, but vehicles without scheduled leaving times may not be charged at all
Solution Approach 1:
The system automatically determines charging priorities based on charge history information without requiring users to manually specify leaving times. The controller autonomously analyzes connection time and SOC data to classify vehicles into appropriate charging groups, eliminating the need for user intervention while ensuring fair charging distribution.
Solution Approach 2:
The system changes the charging control parameter from user-specified leaving time to objective charge history information (connection time and SOC). By using measurable parameters from the vehicle's charging behavior, the system dynamically adjusts charging priorities without relying on subjective user input, thereby preventing vehicles without leaving time specifications from being overlooked.
2Ease of operation
If even-charging control means charges vehicles evenly and sequentially, then all vehicles are charged fairly, but vehicles with scheduled leaving times may not be charged in time
Solution Approach 1:
The system applies different charging strategies to different groups of vehicles based on their charge history characteristics. Vehicles with similar connection times and SOC levels are grouped together and charged according to their specific needs, rather than applying a uniform charging sequence to all vehicles. This localized approach ensures both fairness and timeliness.
Solution Approach 2:
The charging priority classification is dynamically adjusted based on real-time charge history information. As vehicles connect and disconnect, and as SOC levels change, the controller continuously reevaluates and reclassifies vehicles into appropriate charging groups, making the charging distribution adaptive and responsive to changing conditions rather than static.
