Modular Battery Charging Assembly for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electric vehicle battery charging systems are inefficient, as they require lengthy charging times and lack a convenient battery exchange service, limiting their adoption and maintenance capabilities.
Innovation Solution
A detachable modulized battery charging assembly with multiple charging units, a managing unit for controlling and tracking battery status, and a user interface for communication, allowing for quick battery exchange and efficient management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional charging stations are used to charge batteries, then batteries can be charged, but charging takes hours which is too long for users
Solution Approach 1:
The charging system is segmented into separate functional modules: battery removal unit, charging unit, and battery installation unit. This allows the battery to be quickly exchanged rather than charged in place, reducing user waiting time from hours to minutes while maintaining charging functionality.
Solution Approach 2:
Batteries are pre-charged at the charging station before users need them. When a user's battery is depleted, a fully charged battery is already available for immediate exchange, eliminating the need for users to wait during the charging process.
2Adaptability or versatility
If batteries are kept in fixed charging stations, then charging can be provided, but the system lacks flexibility in placement and configuration
Solution Approach 1:
The charging assembly is divided into independent modular units that can be configured in different arrangements (e.g., side-by-side, stacked) and placed in various locations. Each module contains complete functionality, allowing flexible deployment without increasing overall system complexity.
Solution Approach 2:
The modular charging units are designed with universal interfaces and standardized configurations that can serve multiple purposes and be arranged in different layouts, providing adaptability to various installation environments while maintaining simple, repeatable system architecture.
3Loss of time
If battery exchange service is implemented, then user waiting time is reduced, but complex management systems are needed to track and control batteries
Solution Approach 1:
The charging assembly incorporates automatic battery identification and tracking through RFID tags and control units that autonomously manage battery status, location, and charging state. This self-service capability reduces the need for complex manual management systems while enabling efficient battery exchange operations.
Solution Approach 2:
The system uses RFID recognition and control units to continuously monitor and provide feedback on battery status, charging state, and user interactions. This automated feedback mechanism simplifies management by providing real-time information without requiring complex manual tracking systems.
