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 prevent excessive high-temperature exposure and high state of charge periods.
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 remains at high temperature for an extended period which accelerates deterioration
Solution Approach 1:
The system performs preliminary heating of the spare battery based on predicted demand and actual usage status. The controller determines an appropriate heating start time by considering both prediction information and real-time conditions, enabling the battery to be ready sooner without excessive high-temperature exposure.
Solution Approach 2:
The system uses feedback from usage status information to adjust the heating timing. The controller monitors actual battery usage patterns and outdoor temperature conditions, then modifies the heating schedule accordingly to prevent premature or excessive heating that would prolong high-temperature exposure.
2Speed
If the charger charges the spare battery in advance based on predicted demand, then the battery is available sooner, but the battery remains at high state of charge for an extended period which accelerates deterioration
Solution Approach 1:
The system performs preliminary charging of the spare battery based on predicted demand and actual usage status. The controller determines an appropriate charging start time by considering both prediction information and real-time conditions, enabling the battery to be available sooner without excessive high-SOC exposure.
Solution Approach 2:
The system uses feedback from usage status information to adjust the charging timing. The controller monitors actual battery usage patterns and outdoor temperature conditions, then modifies the charging schedule accordingly to prevent premature or excessive charging that would prolong high-state-of-charge exposure.
3Productivity
If the heater starts raising temperature sooner when congestion is high, then battery readiness is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts the heating start time based on real-time congestion levels and usage status. When congestion is high, heating starts sooner to ensure battery availability. When congestion is low, heating is delayed to reduce energy consumption. This dynamic adjustment optimizes the balance between productivity and energy efficiency.

AI summary
A battery replacing system (100) includes: a battery replacing apparatus (10) including at least one battery pack (101) replaceable with a battery pack (201) mounted on a vehicle (200); a heater (30) that raises a temperature of the battery pack (101); and a controller (20). The controller (20) sets a start-of-raising-temperature time (11), at which the heater (30) starts raising the temperature of the battery pack (101), based on usage status information of the battery replacing apparatus (10) and information regarding an outdoor air temperature.
