Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle charging systems face inefficiencies due to poor communication environments and lack of wireless service, limiting effective communication between vehicles and charging stations, particularly in depots or parking lots.
Innovation Solution
A vehicle-to-everything (V2X) charging communication system with multiple communication interfaces, including a first cloud interface for cellular communication and additional RF transceivers for Bluetooth, WiFi, LoRaWAN, and manual control, allowing fleet operators to manage charging and discharging even in areas with limited or no cellular connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single cloud interface with cellular communication is used for V2X charging communication, then the system structure is simple, but communication reliability deteriorates in areas with poor wireless service or no cellular connectivity
Solution Approach 1:
The vehicle communication system is equipped with multiple RF transceivers supporting different communication protocols (cellular, Bluetooth, WiFi, LoRaWAN) to enable universal communication across various environments. This allows the system to adapt to different communication needs and maintain connectivity regardless of the available infrastructure, thereby improving communication reliability without requiring separate dedicated systems for each protocol
Solution Approach 2:
The system dynamically selects and switches between different communication protocols based on environmental conditions and availability. The communication module can transition from cellular to alternative protocols like Bluetooth or WiFi when cellular service is unavailable, ensuring continuous and reliable charging communication adaptability
2Reliability
If multiple communication interfaces are implemented for redundant connectivity, then communication reliability improves in poor wireless environments, but device complexity increases
Solution Approach 1:
Multiple communication protocols are merged into a single integrated communication module within the vehicle's control system. This unified approach allows the system to manage multiple RF transceivers through a common interface, reducing the operational complexity despite having multiple physical communication paths available
Solution Approach 2:
The control system acts as an intermediary that manages and coordinates multiple communication protocols. It selectively activates appropriate protocols based on environmental conditions, simplifying the user experience while maintaining multiple communication paths for improved reliability
3Adaptability or versatility
If cellular-only communication is used for remote charging control, then the system is easy to operate remotely, but communication fails in depot areas with no cellular service
Solution Approach 1:
The communication system changes its operational parameters by switching between different protocols based on environmental conditions. When cellular service is unavailable in depot areas, the system automatically transitions to alternative protocols like Bluetooth or WiFi, maintaining adaptability while ensuring continuous remote charging control capability
