Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems fail to consider temperature elevation and charging timing, leading to prolonged high-temperature exposure of spare batteries, which accelerates deterioration.
Innovation Solution
A battery replacing system that includes a controller to set the start time for temperature elevation and charging based on usage status and outdoor air temperature, adjusting these times to minimize high-temperature exposure and optimize charging efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the heater raises the temperature of the spare battery in advance based on predicted demand, then the battery is ready for use sooner, but the battery is exposed to high temperature for an extended period which accelerates deterioration
Solution Approach 1:
The heater raises the battery temperature in advance based on predicted demand, but the timing is dynamically adjusted using congestion level information. When congestion is high, heating starts earlier; when congestion is low, heating starts later, optimizing the balance between readiness and battery protection
Solution Approach 2:
The heating start time is not fixed but dynamically adjusted based on real-time congestion level information. The controller modifies the heating timing according to actual usage patterns, making the system adaptive to changing conditions
2Speed
If the charger charges the spare battery in advance, then the battery is available for immediate use, but the battery remains in a high state of charge for an extended period which accelerates deterioration
Solution Approach 1:
The charger charges the battery in advance based on predicted demand, but the timing is dynamically adjusted using congestion level information. When congestion is high, charging starts earlier; when congestion is low, charging starts later, optimizing the balance between availability and battery protection
Solution Approach 2:
The charging start time is not fixed but dynamically adjusted based on real-time congestion level information. The controller modifies the charging timing according to actual usage patterns, making the system adaptive to changing conditions
3Device complexity
If the heater and charger operate without considering outdoor air temperature, then the control system is simpler, but the battery temperature management is less efficient
Solution Approach 1:
The controller uses outdoor air temperature information as feedback to adjust heating operations. When the outdoor temperature is high, the heater operates later or not at all, preventing excessive battery temperature accumulation

AI summary
A battery replacing system includes: a battery replacing apparatus including at least one battery pack replaceable with a battery pack mounted on a vehicle; a heater that raises a temperature of the battery pack; and a controller. The controller sets a start-of-raising-temperature time, at which the heater starts raising the temperature of the battery pack, based on usage status information of the battery replacing apparatus and information regarding an outdoor air temperature.
