Electric Vehicle Rescue System With Onboard Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles often face challenges with running out of power during long trips, and existing rescue systems do not provide a solution to recharge the vehicles during towing, leaving them without power upon arrival at a destination.
Innovation Solution
A mobile electric vehicle rescue system equipped with a winch, ramp, and charging unit that can retrieve and recharge the vehicle during transport, utilizing a data processing apparatus for analysis and a network of independent providers for roadside assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flatbed and winch are used to retrieve the electric vehicle, then the vehicle can be transported to a destination, but the vehicle remains without power during and after transport
Solution Approach 1:
The patent combines the transport function (flatbed) with the charging function (charging unit) into a single integrated rescue system. The charging unit is mounted on the mobile platform alongside the winch and flatbed, allowing simultaneous transport and recharging operations, thereby resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The mobile platform is designed to perform multiple functions: it can retrieve disabled vehicles using the winch, transport them on the flatbed, and simultaneously recharge their batteries through the charging unit. This multi-functional design ensures the vehicle remains powered during transport while avoiding the need for separate specialized equipment.
2Reliability
If existing rescue systems only provide towing without charging, then the rescue operation is simple, but the electric vehicle arrives at destination without power
Solution Approach 1:
The charging unit begins recharging the electric vehicle's battery immediately upon arrival at the mobile platform, during the transport process. This preliminary charging action ensures the vehicle arrives at the destination with sufficient power, eliminating the need for post-arrival charging and reducing overall downtime.
Solution Approach 2:
The system maintains continuous useful action by performing both transport and charging operations simultaneously during the same time period. The charging unit operates continuously throughout the transport journey, maximizing battery recharging efficiency and ensuring the vehicle is powered upon arrival without extending the total rescue time.
