EV Battery Rescue Dispatch With Arrival and Completion Time Estimates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle rescue systems fail to provide accurate information on rescue completion time, leading to user anxiety when facing electricity shortages, especially with detachable batteries, as battery replacement or external charging is not efficiently managed.
Innovation Solution
An electric vehicle rescue system that includes a server to manage rescue-ready vehicles equipped with replacement batteries or external power supplies, calculating travel and work times, and notifying users of rescue vehicle information to alleviate anxiety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only arrival time of rescue vehicle is provided, then user can know when the vehicle arrives, but user anxiety about rescue completion is not resolved
Solution Approach 1:
The total rescue time is segmented into two distinct components: travel time (from rescue vehicle departure to arrival at electric vehicle location) and work time (from arrival to completion of battery replacement or charging). This segmentation allows the system to provide detailed time information for each phase, reducing user uncertainty about the overall rescue completion time while maintaining manageable information processing complexity.
2Productivity
If battery replacement is used for quick rescue, then rescue speed is improved, but system must manage multiple rescue-ready vehicles with replacement batteries
Solution Approach 1:
Rescue-ready vehicles are pre-equipped with replacement batteries before rescue operations begin. The system pre-positions these vehicles and prepares replacement batteries in advance, so that when an electric vehicle experiences power loss, the rescue can immediately proceed with battery replacement without delay for battery preparation or charging setup.
Solution Approach 2:
The rescue-ready vehicles are designed with dual functionality: they can perform battery replacement operations and can also provide external charging capabilities. This multi-functionality allows the same vehicle fleet to handle different rescue scenarios (quick battery swap or slower charging) based on availability and user needs, reducing the need for separate specialized vehicle fleets.
3Measurement precision
If rescue vehicle location information is tracked, then responding candidate vehicle can be specified accurately, but information management complexity increases
Solution Approach 1:
A server acts as an intermediary between rescue-ready vehicles and the electric vehicle in need of rescue. The server receives location information from multiple rescue-ready vehicles, processes this data to identify the most suitable responding candidate vehicle based on proximity and availability, and communicates this information to the user. This intermediary approach consolidates information management, reducing the data burden on individual vehicles and users while maintaining high location accuracy.

AI summary
An electric vehicle rescue system includes: an electric vehicle including a detachable battery, the detachable battery being replaceable with a replacement battery and rechargeable by storing power supplied from an external power source; a server configured to receive a rescue request from the electric vehicle; and rescue-ready vehicles communicatively connected to the server, each of the rescue-ready vehicles being possible to be sent to the electric vehicle in response to the rescue request. Each of the rescue-ready vehicles includes the replacement battery, or the external power supply capable of charging the detachable battery of the electric vehicle. The server includes: a storage unit; a specifying unit; a first calculation unit; a second calculation unit; and a notification unit.
