EV Charging Policy Synchronization for Battery Status Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle charging technologies do not adapt charging policies to the current performance status of the vehicle's power battery, leading to accelerated battery degradation and safety hazards due to inconsistent charging practices across different service providers.
Innovation Solution
A method and system that compares the generation sequences of charging policies between terminals to determine the newer policy, which is then used to configure charging parameters, ensuring they align with the current battery status for improved lifespan and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed charging policy is used across different service providers, then charging operations are simple and standardized, but the battery lifespan and safety deteriorate due to inconsistent charging practices not adapting to current battery status
Solution Approach 1:
The patent implements feedback mechanisms where charging policies are dynamically adjusted based on battery status information. The system collects battery data (temperature, voltage, current, state of charge) and uses this feedback to modify charging parameters in real-time, ensuring safety while adapting to changing battery conditions across different service providers
Solution Approach 2:
The charging policy transitions from a static fixed approach to a dynamic adaptive system. The policy automatically adjusts charging parameters based on real-time battery status, service provider characteristics, and environmental conditions, allowing the system to optimize for both safety and performance without manual intervention
2Productivity
If fast charge technology is used to charge battery to 80% SOC in short time, then user mileage anxiety is reduced, but battery degradation accelerates and lifespan shortens
Solution Approach 1:
The system dynamically adjusts charging speed based on real-time battery status. When battery conditions permit, fast charging is applied to reduce charging time and address mileage anxiety. When degradation risks are detected (temperature elevation, voltage thresholds), the system automatically modulates charging rate to protect battery lifespan, achieving an optimal balance between speed and durability
Solution Approach 2:
The charging parameters (current, voltage, power) are continuously changed based on battery state of charge, temperature, and health status. The system transitions between different charging phases and rates, adjusting parameters to maximize charging speed during safe operating windows while preventing degradation during critical thresholds
3Adaptability or versatility
If charging policies from different service providers are not synchronized, then each provider maintains independent control, but charging consistency and battery performance deteriorate
Solution Approach 1:
The patent creates a universal charging policy framework that can operate across multiple service providers. The system establishes common standards and communication protocols that enable consistent battery management regardless of which provider's charging infrastructure is used, while still allowing adaptation to provider-specific characteristics and capabilities

AI summary
Embodiments of this application provide a charging control method, apparatus, and system, a server, and a medium. A generation sequence of a charging policy stored in a first terminal and a generation sequence of a charging policy stored in a second terminal are compared in the first terminal, to determine a relatively new charging policy in the first terminal and the second terminal as a target charging policy. The target charging policy is used to subsequently configure a charging parameter, so that a charging parameter configured in a charging process can be better adapted to a current performance status of a power battery of a vehicle, to improve a lifespan and charging safety of the power battery of the vehicle.
