Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing charging fee estimation methods for electric vehicles are inaccurate due to decreased battery temperature, leading to deviations between estimated and actual costs, which reduces charging efficiency.
Innovation Solution
An information processing method that acquires battery temperature information, estimates the charging period and fee, calculates the reduction in fee when the battery temperature is raised, and notifies the user terminal of the necessary work and reduction amount, thereby improving estimation accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If charging fee estimation is performed without considering battery temperature, then the estimation process is simple, but the estimation accuracy deteriorates
Solution Approach 1:
The patent applies parameter changes by incorporating battery temperature as an additional parameter into the charging fee estimation model. The estimation system adjusts the charging period and fee calculations based on temperature-dependent battery charging characteristics, transforming the estimation from a simple time-based calculation to a temperature-aware predictive model that accounts for varying charging speeds at different temperatures
Solution Approach 2:
The patent implements preliminary action by performing temperature-based charging period estimation before the actual charging process begins. The system predicts the charging duration and fee in advance by considering the battery's temperature state, allowing users to make informed decisions about charging reservations without undergoing complex real-time calculations during charging
2Reliability
If battery temperature is low, then charging speed decreases, but the existing estimation method does not account for this, leading to cost deviation
Solution Approach 1:
The patent implements feedback by continuously monitoring battery temperature and using this information to adjust charging fee estimations. The system establishes a feedback loop where temperature measurements inform charging period predictions, which in turn affect fee calculations, ensuring that the estimation reflects actual charging conditions and improves cost reliability
Solution Approach 2:
The patent changes the estimation parameters by incorporating temperature-dependent charging characteristics. Instead of using fixed charging speed assumptions, the system adjusts charging period estimates based on temperature-based charging curves, accounting for reduced charging efficiency at low temperatures while maintaining accurate cost predictions
