Engineering Contradiction Analysis
1Reliability
If continuous temperature regulation is performed on the battery when the vehicle is unattended, then the battery temperature is maintained within an appropriate range, but power consumption of the temperature regulating device increases
Solution Approach 1:
The control device performs preliminary prediction of future battery temperature based on outside temperature information before the vehicle is started. This allows the system to pre-determine the optimal operating state of the temperature regulating device, avoiding unnecessary continuous operation and reducing power consumption while ensuring the battery temperature will be appropriate when needed
Solution Approach 2:
The system utilizes outside temperature information (environmental data) to predict battery temperature trends, allowing the battery temperature management to partially self-regulate based on environmental conditions. The control device only intervenes when necessary based on the prediction, reducing unnecessary energy consumption of the temperature regulating device
2Use of energy by moving object
If no temperature regulation is performed on the battery when the vehicle is unattended, then power consumption is reduced, but the battery temperature may deviate from the appropriate range leading to deterioration
Solution Approach 1:
The control device performs preliminary prediction of future battery temperature based on outside temperature information before the vehicle is started. This advance prediction allows the system to identify when temperature regulation will be necessary, ensuring the battery temperature will be within the appropriate range when the vehicle is operated, thereby preventing battery deterioration without requiring continuous regulation
Solution Approach 2:
The system uses outside temperature information as feedback to predict future battery temperature states. This predictive feedback mechanism allows the control device to make informed decisions about when to activate the temperature regulating device, ensuring battery temperature maintenance while minimizing unnecessary energy consumption

AI summary
A battery temperature regulating method includes: acquiring outside temperature information representing a future outside temperature transition around the vehicle, searching for an intersection time, which is a time when the outside temperature becomes a threshold temperature, predicting, based on the outside temperature information, a future temperature transition of the battery when it is assumed that predetermined temperature regulation is performed each time the battery reaches the threshold temperature, creating a temperature regulating plan for the battery, which is performed by the temperature regulating device, based on a search result of the intersection time and a prediction result of the temperature transition of the battery, and controlling the temperature regulating device based on the temperature regulating plan. In the processing of creating the temperature regulating plan, the temperature regulating plan in which details of the temperature regulation performed when the battery once reaches the threshold temperature is adjusted is created.
