Solution Overview
Problem
Electric vehicles face challenges in obtaining a jump start when their energy storage is depleted, as conventional jump leads with combustion engines cannot provide the necessary electrical energy due to voltage differences and the inability to recharge using an alternator.
Innovation Solution
A jumper cable with a converter that simulates a charging station, allowing communication with electric vehicles and providing sufficient energy to enable them to reach a charging point, compatible with all vehicles having internal combustion engines without requiring adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional jump lead is used to provide electrical energy from a combustion engine vehicle, then the jump start process is simple and easy to operate, but the voltage levels and energy supply are insufficient for electric vehicles
Solution Approach 1:
The patent introduces a converter as an intermediary device between the combustion engine vehicle's battery and the electric vehicle's charging system. This converter transforms the 12V DC output from the conventional vehicle into appropriate AC or DC voltages (230V AC, 400V DC, or 800V DC) that the electric vehicle can accept, thereby enabling power transfer while resolving the voltage and power incompatibility issue
Solution Approach 2:
The converter dynamically changes electrical parameters including voltage level (from 12V to 230V/400V/800V), current, and frequency to match the requirements of the electric vehicle's charging system. This parameter transformation allows the conventional vehicle's battery to provide sufficient power to the electric vehicle despite the initial power and voltage mismatch
2Power
If a converter is added to transform voltage levels and simulate a charging station, then sufficient electrical energy can be provided to the electric vehicle, but the device complexity increases
Solution Approach 1:
The converter is designed to perform multiple functions: it acts as a voltage transformer, a protocol simulator (mimicking a charging station), and a communication interface. By consolidating these functions into a single device, the patent reduces overall system complexity despite the advanced capabilities required
Solution Approach 2:
The converter copies the electrical and communication characteristics of a real charging station, allowing the electric vehicle to recognize and communicate with it as if it were a genuine charging infrastructure. This copying approach simplifies integration by leveraging existing vehicle charging protocols without requiring custom modifications to the electric vehicle
3Adaptability or versatility
If the jumper cable is designed to work with all conventional vehicles without adjustments, then versatility and ease of use are improved, but ensuring compatibility across different voltage levels and protocols becomes more difficult
Solution Approach 1:
The converter dynamically adapts to different vehicle types and charging requirements by adjusting its output parameters in real-time. It can switch between AC and DC output modes, adjust voltage levels, and modify communication protocols based on the connected electric vehicle's specifications, enabling universal compatibility without requiring multiple specialized devices
