Solution Overview
Problem
The charging rate of new energy vehicle batteries is influenced by temperature, and existing methods for adjusting battery temperature during charging are inefficient, leading to prolonged charging times and suboptimal charging rates.
Innovation Solution
An adjustment method that involves an electronic apparatus receiving a message to adjust the battery temperature to a target range (25° C. to 40° C.) before the vehicle reaches a charging station, using thermal management systems and battery management systems to optimize temperature based on charging station conditions and battery state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If battery temperature is adjusted during charging, then charging rate is improved, but charging time is prolonged due to temperature adjustment delays
Solution Approach 1:
The system performs preliminary temperature adjustment before the vehicle arrives at the charging station by receiving advance charging information and pre-controlling the battery temperature to the optimal charging range. This preliminary action eliminates the need for temperature adjustment during charging, thereby resolving the contradiction between improving charging rate and reducing charging time.
2Productivity
If battery temperature is adjusted to optimal range, then charging efficiency is increased, but energy consumption increases
Solution Approach 1:
The system performs preliminary temperature adjustment before the vehicle arrives at the charging station. By receiving advance charging information and pre-controlling the battery temperature, the system ensures optimal charging conditions are already in place, avoiding additional energy consumption during the charging process itself.
Solution Approach 2:
The system dynamically adjusts battery temperature control parameters based on received charging information, including charging power requirements and expected charging duration. By changing temperature control parameters in advance according to specific charging scenarios, the system optimizes charging efficiency while minimizing energy consumption for temperature adjustment.
