Vehicle Accessory Identification for Battery Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging for passengers in recreational and utility vehicles to identify which accessories are being powered by the vehicle when multiple accessories are connected simultaneously, leading to difficulties in managing power distribution and ensuring sufficient energy for the vehicle's destination.
Innovation Solution
A vehicle system with a user interface, electrical power supply, chargeable storage, and a controller that detects connected accessories, determines their identifiers, and manages power distribution by alerting or automatically turning off power outlets to conserve energy, ensuring sufficient charge for the vehicle's destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple removable accessories are connected to the chargeable storage simultaneously, then the power supply capacity is improved, but the ability to identify and manage individual accessories deteriorates
Solution Approach 1:
The controller provides feedback by detecting which accessories are connected and displaying their identifiers on the user interface. This feedback loop allows users to identify connected accessories and manage power distribution informedly, resolving the information loss problem when multiple accessories are connected simultaneously.
Solution Approach 2:
The controller acts as an intermediary between the power supply system and the user. It detects accessory connections, determines their identifiers, and communicates this information through the user interface, enabling users to manage multiple connected accessories without confusion.
2Adaptability or versatility
If power is provided to multiple accessories simultaneously, then the utility and power export capability are improved, but the risk of insufficient energy for vehicle destination increases
Solution Approach 1:
The controller performs preliminary detection of connected accessories and their power requirements before power distribution begins. By determining accessory identifiers and evaluating available power capacity in advance, the system can prevent energy insufficiency before it occurs, while still allowing multiple accessories to be powered when capacity permits.
Solution Approach 2:
The system dynamically adjusts power distribution based on real-time conditions. The controller continuously monitors the state of charge and power capacity, enabling or disabling power outlets as needed to maintain sufficient energy for the vehicle's destination while maximizing power export capability when possible.
3Loss of energy
If the controller monitors and manages power distribution to accessories, then the energy efficiency is improved, but the system complexity increases
Solution Approach 1:
The controller performs multiple functions including detecting connected accessories, determining their identifiers, monitoring power capacity, evaluating energy sufficiency, and controlling power outlet states. By consolidating these diverse functions into a single controller, the system achieves efficient energy management without proportionally increasing overall system complexity.

AI summary
A vehicle is electrically connected to one or more removable accessories. The vehicle includes a user interface, an electrical power supply, a chargeable storage, and a controller. The controller may be configured to detect the one or more removable accessories that are connected to the at least one power outlet, determine an identifier associated with each of the one or more detected removable accessories, and cause the user interface to display one or more identifiers associated with the one or more detected removeable accessories.
