EVSE Charging Priority Control for Shared Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Electric Vehicle Supply Equipment (EVSE) systems lack user-accessible and flexible options for customizing charging patterns, leading to complex power resource sharing and hesitance in prioritizing charging among multiple vehicles.
Innovation Solution
The EVSE system includes a terminal block, display unit, and current load controller with a selector for defining customized current loads, enabling easy and secure power distribution management through a communication module that synchronizes current loads across connected EVSEs, allowing for dynamic priority setting and flexible charging schemes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EVSE systems use complex power resource sharing options, then power distribution control capability is improved, but user accessibility and ease of operation deteriorates
Solution Approach 1:
The system segments power resource sharing into distinct priority levels (first priority, second priority, etc.), allowing users to select from predefined options rather than configuring complex parameters. This segmentation simplifies user interaction while maintaining versatile power distribution control across multiple vehicles.
Solution Approach 2:
The system pre-configures multiple priority-based charging patterns that are stored and readily available for selection. Instead of requiring users to create custom configurations, the preliminary action of pre-setting these patterns enables users to simply select from existing options, improving ease of operation while maintaining adaptability.
2Adaptability or versatility
If EVSE systems implement flexible charging patterns for multiple users, then adaptability is improved, but system complexity increases
Solution Approach 1:
The system dynamically adjusts charging current distribution based on selected priority levels and predefined patterns. The current load controller automatically modifies power allocation in real-time according to the chosen configuration, providing flexible charging patterns without requiring complex manual adjustments or increasing system complexity.
Solution Approach 2:
The system changes operational parameters (current load distribution, priority levels) based on predefined patterns rather than requiring complex configuration. By parameterizing the charging behavior into selectable patterns, the system achieves flexibility while maintaining simplicity in implementation and user interaction.
3Adaptability or versatility
If EVSE systems provide priority charging for some vehicles over others, then charging prioritization capability is improved, but power resource sharing complexity increases
Solution Approach 1:
The system segments vehicles into distinct priority groups (first priority, second priority, etc.), simplifying the management of multiple vehicles. This segmentation approach enables clear prioritization capability while avoiding the complexity of individual vehicle configuration, as all vehicles in the same priority group are treated uniformly.
Solution Approach 2:
The system implements prioritization through partial action by focusing on priority level assignment rather than comprehensive individual vehicle management. This approach provides sufficient prioritization capability for typical use cases without implementing excessive complexity, as the system handles vehicles in groups rather than individually.
