Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle service platforms lack the ability to regularly identify the type of charging pile used during the charging process, requiring significant workload and design upgrades in the vehicle's communication device.
Innovation Solution
A method and apparatus for recognizing charging pile types by determining the proportion of preset power charging capacity based on charging parameters, such as charging voltage and current, within a preset time period, allowing the service platform to differentiate between Alternating Current and Direct Current charging piles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an additional field and identifier are designed in the vehicle's communication device to report charging pile type, then charging pile type identification capability is improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The patent introduces an intermediary calculation approach by using the service platform to compute the charging pile type based on existing charging parameters (voltage, current, power) rather than directly transmitting the type identifier. This mediator (service platform) processes the data using predefined formulas, eliminating the need for additional communication fields while achieving the same information transfer goal.
Solution Approach 2:
The patent replaces the mechanical/system-level solution (adding hardware fields and identifiers in the communication device) with a computational/mathematical approach. By substituting the physical communication structure with calculation-based type determination, the system avoids hardware modifications while achieving type identification.
2Loss of information
If unified upgrade and planning of communication device design is implemented, then charging pile type reporting capability is improved, but workload and implementation difficulty increase
Solution Approach 1:
The patent uses existing charging parameters (voltage, current, power) that are already being collected and transmitted as copies or proxies for determining charging pile type. Instead of creating new communication structures, the system leverages copies of existing data to infer the required information, avoiding unified upgrades.
Solution Approach 2:
The service platform performs self-service by autonomously calculating the charging pile type using existing data and predefined formulas. This eliminates the need for external coordination, unified planning, and collaborative upgrades across multiple systems, as the platform independently derives the information from available parameters.
3Ease of operation
If charging pile type is not identified, then communication device design remains simple, but service platform cannot provide targeted charging services
Solution Approach 1:
The patent determines charging pile type by analyzing changes and relationships among existing charging parameters (voltage, current, power) rather than requiring direct type identification. By examining how these parameters vary and relate to each other, the system infers pile type information, maintaining design simplicity while enabling service adaptability.

AI summary
A charging pile type recognition method includes: obtaining a charging parameter of an electric vehicle within a preset time period; determining a proportion of a preset power charging capacity of a charging pile within the preset time period according to the charging parameter, wherein the proportion of the preset power charging capacity is equal to a ratio of a first amount of electricity charged into the electric vehicle by the charging pile at a preset power within the preset time period to a total amount of electricity charged into the electric vehicle by the charging pile within the preset time period; and determining a type of the charging pile according to the proportion of the preset power charging capacity.
