Solution Overview
Problem
Battery electric vehicles (BEVs) face challenges in jump-starting due to the lack of a suitable method to transfer electrical charge between vehicles, unlike conventional internal combustion-powered vehicles.
Innovation Solution
A battery electric vehicle jumper cable system that includes electrical plugs and cables for connecting between standard charging ports of two BEVs, with a battery energy control module configured to transfer electrical current from one BEV's battery pack to another, enabling jump starting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional jumper cables are used for internal combustion-powered vehicles, then battery jump starting is achieved, but battery electric vehicles cannot be jump started due to lack of suitable connection interface
Solution Approach 1:
The jumper cable system uses standard charging port interfaces that are universally compatible with battery electric vehicles, allowing the same cable design to work across different BEV models. The plugs are designed to mate with conventional charging port receptacles, enabling the jumper cable to serve multiple BEV types without requiring model-specific adaptations.
2Reliability
If direct battery connection is attempted in battery electric vehicles, then electrical charge transfer is possible, but safety risks increase due to high voltage systems
Solution Approach 1:
The system introduces a charging port interface as an intermediary between the two battery packs, which includes built-in safety mechanisms, insulation, and control circuitry. This intermediary component mediates the high-voltage connection, providing galvanic isolation, overcurrent protection, and proper signal handshaking, thereby enabling safe charge transfer without direct battery-to-battery contact.
Solution Approach 2:
The charging port interfaces incorporate feedback mechanisms that monitor connection status, voltage levels, and current flow during the jump-start process. The system continuously communicates between the donor and recipient vehicles to ensure safe operation, automatically adjusting or terminating charge transfer based on real-time conditions detected at the interface level.
3Ease of operation
If battery electric vehicles are stranded with depleted batteries, then mobility is lost, but conventional jump starting methods are incompatible with BEV charging systems
Solution Approach 1:
The jumper cable system is designed with plugs that are compatible with standard charging port receptacles found on various battery electric vehicles. This universal design allows the same jumper cable to be used across different BEV models and manufacturers, enabling easy operation without requiring vehicle-specific adapters or specialized equipment.
