Solution Overview
Problem
Current electric vehicles have limited travel distance on a single charge, requiring frequent recharging and long waiting times, which restricts their usability and convenience.
Innovation Solution
The Dual Drive Electric Vehicle with Unlimited Range Drive (URD) system employs intelligent battery modules and a high voltage continuous variable power plant, allowing batteries to recharge while in use, dynamically switching between battery sets to extend travel range, utilizing both lithium-ion and solid-state batteries for extended battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If electric vehicles use conventional battery charging systems, then the vehicle can be recharged, but the recharging time is long (30-60 minutes) and travel distance is limited (200-300 miles per charge)
Solution Approach 1:
The patent divides the single battery system into dual battery sets (first and second battery sets), allowing one battery to power the vehicle while the other charges simultaneously. This segmentation enables continuous operation without stopping for recharging, effectively eliminating recharging time loss and extending travel distance beyond conventional limits.
Solution Approach 2:
The system maintains continuous useful action by switching between two battery sets. While one battery is depleted, the other provides power; when the first needs charging, the second takes over driving duties while the first recharges. This continuity eliminates idle recharging time and ensures the vehicle is always in operational state, achieving unlimited range capability.
2Ease of operation
If electric vehicles use wired charging ports, then batteries can be recharged, but the charging process requires vehicle stoppage and occupies charging infrastructure
Solution Approach 1:
The patent replaces the mechanical wired charging port system with a wireless electromagnetic induction charging system. The wireless charging port uses electromagnetic fields to transfer energy without physical connection, eliminating the need for plugging and unplugging operations. This substitution significantly improves charging convenience and reduces the time required to connect and begin charging.
Solution Approach 2:
The system enables self-service charging through automatic battery management. The controller automatically monitors battery charge levels and switches between battery sets without driver intervention. When one battery is depleted, the system automatically switches to the other battery and initiates charging of the depleted one, eliminating the need for driver action during the charging process.
3Duration of action of moving object
If electric vehicles use single battery set, then the system is simple, but the travel range is limited and requires frequent recharging
Solution Approach 1:
The patent merges two complete battery sets into a unified dual-battery system with integrated control. Both battery sets are connected to the same motor controller and charging system, allowing them to work together as a single extended energy reservoir. This merging approach doubles the effective range while sharing common control infrastructure, thereby limiting the increase in system complexity.
Solution Approach 2:
The controller is designed with multi-functionality to manage both battery sets universally. It can operate in single-battery mode for short trips, switch between batteries for extended range, coordinate wireless charging for one battery while the other powers the vehicle, and balance charge distribution. This universal controller handles multiple operational scenarios without requiring separate control systems for each battery, managing complexity through functional integration.
