This paper designs and develops an emergency rescue service for electric vehicles (EVs), which may suffer from the battery depletion during their trips. After building relevant data models on both chargers and EVs, our design defines the interaction among three parties of EV drivers, the rescue server, and rescue vehicles to responsively process the dispatch request and systematically meet the user requirement. Particularly, a comprehensive mobile application is developed on the Android operating system to help users to promptly send a rescue request to the server and monitor the request processing status. This user interface allows EV drivers to automatically specify their locations and necessary personal information as well as to view the distribution of emergency vehicles through user-friendly maps. Our design is scalable for a large number of emergency vehicles and rescue requests, accelerating the wide deployment of EVs in our daily lives. Moreover, the rescue system design can collaborate with an EV tracking system and charge reservation agents to create a more sophisticated EV information service.
