Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenience and high burden of charging electrification vehicles due to long charging times and the lack of charging infrastructure, leading to low battery anxiety and inefficient charging processes.
Innovation Solution
A battery charging service system utilizing a mobile charger with an energy storage system (ESS) and a network-connected service device that classifies vehicles by position and battery capacity, providing targeted charging services and collecting big data for optimized charging strategies, including autonomous vehicle navigation and charging based on reference values for battery capacity and infrastructure availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user directly connects a charging socket to a power supply for charging, then charging can be performed, but charging time is long (4-5 hours for slow charging, 35 minutes for rapid charging) and causes high charging burden
Solution Approach 1:
The system performs preliminary actions by automatically monitoring battery capacity and positioning vehicles before charging is needed. The working device proactively navigates to vehicles and initiates charging processes without user intervention, performing all necessary actions in advance before the user would need to charge.
Solution Approach 2:
The charging system operates autonomously without requiring user service. The working device automatically detects vehicles needing charging, navigates to them, connects charging equipment, and manages the entire charging process. The system serves itself by monitoring its own operational status and automatically dispatching resources.
2Productivity
If charging infrastructure is limited, then users must wait for charging and move vehicles after charging, but this reduces charging efficiency and increases user inconvenience
Solution Approach 1:
The system transforms the static charging infrastructure into a dynamic mobile service. Instead of fixed charging stations, working devices move autonomously to provide charging services wherever vehicles are located. This dynamic approach allows multiple vehicles to be served sequentially without requiring users to wait at fixed infrastructure points.
Solution Approach 2:
The working device acts as an intermediary between the power supply and vehicles. It carries charging equipment and power delivery capability, serving as a mobile intermediary that can reach any vehicle regardless of fixed infrastructure availability. This eliminates the need for users to wait at charging stations or move vehicles to specific locations.
3Area of stationary object
If the service area is large with many vehicles, then comprehensive coverage is needed, but this increases system complexity and resource requirements
Solution Approach 1:
The service area is divided into multiple zones managed by different working devices. The service device segments the large area into smaller manageable regions, assigning each working device to specific zones. This segmentation reduces the complexity each individual device must handle while maintaining comprehensive coverage through coordinated operation of multiple devices.
Solution Approach 2:
Working devices are designed as multi-functional units that can perform various operations: monitoring vehicle status, navigating to different locations, connecting to different vehicle types, and managing charging processes. This universality allows a single device type to handle diverse tasks across the entire service area, reducing overall system complexity compared to having specialized devices for each function.

AI summary
A battery charging service system for an electrification vehicle and a method thereof are provided. The battery charging service system includes a mobile charger including at least one energy storage system (ESS), a working device that provides a battery charging service using the mobile charger, and a service device connected with the working device over a network. The service device collects a position and a remaining battery capacity of a user’s vehicle, classifies a target vehicle which needs battery charging in a service area based on the position and the remaining battery capacity of the user’s vehicle, and transmits a work instruction to the working device taking charge of the service area.
