Mobile Battery Pool Management Server for EV Charging Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to manage and provide information on mobile rechargeable batteries for electric vehicles, including their availability at current and estimated arrival times, to support the growing demand for electric vehicle charging infrastructure.
Innovation Solution
A management server system that displays available mobile rechargeable batteries at selected stations based on user location and estimated arrival time, adjusts battery pools by adding or removing batteries as needed, and tracks provider reliability based on delivery performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile rechargeable battery pools are managed at multiple stations, then charging service coverage and accessibility are improved, but system complexity and management difficulty increase
Solution Approach 1:
The system divides the battery management function into separate modules: user devices for querying and reserving, station devices for local battery pool management, and a central management server for coordination. This segmentation allows expanded service coverage while keeping each component's complexity manageable.
Solution Approach 2:
A central management server acts as an intermediary between user devices and multiple station devices, coordinating battery reservations, tracking availability, and managing the distributed battery pools. This mediator handles the complexity of multi-station coordination centrally while allowing local stations to remain relatively simple.
2Reliability
If battery availability information is provided at estimated arrival time, then user convenience and service reliability are improved, but information management complexity increases
Solution Approach 1:
The system performs preliminary actions by calculating estimated arrival times and predicting battery availability in advance. The management server proactively determines which batteries will be available when users arrive, allowing users to reserve batteries before traveling to stations with confidence that the batteries will be ready.
Solution Approach 2:
The system implements feedback mechanisms where the management server continuously monitors battery status at all stations, updates availability information in real-time, and notifies users of changes. This feedback loop ensures accurate reliability information is provided to users while automating the information management process.
3Productivity
If battery pools are dynamically adjusted by adding or removing batteries, then resource utilization efficiency is improved, but operational complexity increases
Solution Approach 1:
The battery pools at each station are made dynamic rather than static. The management server enables batteries to be added to or removed from station pools based on real-time demand, availability, and user reservations. This dynamic adjustment optimizes resource utilization across the network while the automated server handling reduces operational complexity.

AI summary
A method and server for managing mobile rechargeable battery pools of multiple stations, comprising steps of: (a) in a response to a selection of a specific location, the management server displaying pieces of location information on the stations by referring to a current location of the specific user and the specific location; (b) in a response to a selection of a k-th station among the stations, the management server displaying (i) information on (k_1)-st mobile rechargeable batteries available at a current time and (ii) information on (k_2)-nd mobile rechargeable batteries available at an estimated arrival time; and (c) in a response to a selection of a specific k-th mobile rechargeable battery, by the user device for a future need, the management server sending information on the future need to an administrator device or a provider device.
