Vehicle Navigation for Battery Swap or Charging Site Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems for vehicles with replaceable energy storage devices do not adequately enhance user convenience, as guiding to energy supply facilities can result in long wait times or low performance, degrading convenience.
Innovation Solution
A navigation system that guides vehicles to replacement or supply sites based on predetermined conditions, such as equipment availability and energy storage device compatibility, to optimize user convenience by avoiding unsuitable locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the vehicle is guided to a supply site where an energy supply facility is provided, then the vehicle can receive energy supply, but the wait time may be long because all energy supply facilities existing around the vehicle have many users
Solution Approach 1:
The navigation system dynamically selects between supply sites and replacement sites based on real-time conditions such as user quantity, facility performance, and vehicle equipment status. This dynamic decision-making adapts to changing circumstances to minimize wait time while ensuring energy supply.
Solution Approach 2:
The system provides a alternative solution (replacement site) that achieves the same goal (energy supply) through a different mechanism (device replacement rather than facility charging), bypassing the congestion at supply facilities.
2Use of energy by moving object
If the vehicle is guided to a supply site where an energy supply facility is provided, then the vehicle can receive energy supply, but a long time may be required for the energy storage device to be supplied with sufficient energy because all energy supply facilities existing around the vehicle have low performance
Solution Approach 1:
The navigation system dynamically evaluates facility performance metrics and adjusts routing decisions accordingly, selecting facilities that meet minimum performance thresholds or alternatively directing to replacement sites when facility performance is insufficient.
Solution Approach 2:
The system offers an alternative energy supply approach through replacement sites where energy storage devices can be swapped, achieving rapid energy replenishment without being constrained by facility charging speed limitations.
3Ease of operation
If the vehicle is guided to a supply site, then user convenience may be enhanced, but the vehicle may be unequipped with equipment for allowing an energy supply from an energy supply facility to the energy storage device
Solution Approach 1:
The navigation system checks vehicle equipment compatibility with potential supply sites before generating routing instructions, performing this verification in advance to avoid guiding users to incompatible locations and ensuring convenient energy supply.
4Adaptability or versatility
If the navigation system guides the vehicle to both replacement site and supply site, then energy resupply options are increased, but the device complexity increases
Solution Approach 1:
The navigation system segments the energy resupply function into distinct pathways (supply site routing and replacement site routing), allowing independent evaluation and selection of each option based on current conditions, thereby managing complexity through functional separation.

AI summary
A navigation system configured to guide a vehicle including an energy storage device which is attachable and detachable is provided. The navigation system includes a guiding device configured to present information for guiding the vehicle to at least one of a replacement site and a supply site. The replacement site is a site where the energy storage device is replaced. The supply site is a site where an energy supply facility is provided, the energy supply facility supplying energy to the energy storage device. The guiding device is configured to guide the vehicle to the supply site when a predetermined condition is met, and to not guide the vehicle to the supply site when the predetermined condition is not met.
