Battery Exchange Network for Electric Vehicle Range and Cost
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The adoption of all-electric vehicles is hindered by high costs and limited driving range due to expensive secondary batteries and long recharging times, particularly in densely populated cities with limited financial resources.
Innovation Solution
A network of collection, charging, and distribution machines, akin to kiosks or vending machines, that maintain a stock of fully charged batteries, allowing users to swap or exchange depleted batteries for charged ones, optimizing battery usage based on user profiles and driving habits, and employing a security system for controlled energy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If users purchase expensive secondary batteries for all-electric vehicles, then they can achieve zero tailpipe emissions, but the financial cost becomes prohibitive for many users
Solution Approach 1:
The battery system is segmented into multiple individual battery units that can be independently purchased, rented, or exchanged. Users don't need to buy an expensive complete battery pack, but can instead acquire individual cells or modules, significantly reducing the upfront financial barrier while still enabling zero-emission operation
Solution Approach 2:
The system enables users to self-serve by allowing them to exchange depleted batteries for charged ones at automated kiosks or service stations. This eliminates the need for expensive proprietary service contracts and reduces dependency on expensive manufacturer maintenance programs
2Quantity of substance
If users use standard secondary batteries with limited capacity, then the vehicle cost is reduced, but the driving range becomes insufficient for practical use
Solution Approach 1:
The total battery capacity needed for adequate driving range is segmented into multiple smaller battery units. Users can start with a single battery unit for short trips and progressively acquire additional units to extend their effective driving range, paying only for the capacity they actually need at each stage
Solution Approach 2:
Battery units are pre-charged at centralized facilities before being made available for exchange. This preliminary charging action allows users to quickly swap depleted batteries for fully charged ones, effectively extending their operational range without requiring large, expensive battery packs in their vehicles
3Quantity of substance
If users rely on traditional recharging methods, then battery cost can be managed, but the recharging time becomes unacceptably long
Solution Approach 1:
Batteries are pre-charged to full capacity at centralized charging facilities before being distributed for exchange. This preliminary charging action transfers the time burden from the user (who only needs to swap batteries in minutes) to the charging infrastructure (which charges batteries during off-peak hours or overnight), effectively eliminating perceived recharging wait time for users
Solution Approach 2:
The recharging function is extracted from the user's vehicle and relocated to centralized charging facilities. Users no longer need to wait for their vehicles to charge; instead, they exchange pre-charged batteries at convenient locations, separating the charging process from the user's immediate needs
4Loss of time
If a battery exchange system is implemented, then recharging time is reduced, but the system complexity increases
Solution Approach 1:
A standardized battery interface and exchange protocol acts as an intermediary between users, vehicles, and charging infrastructure. This standardization layer simplifies the exchange process to a few straightforward steps while managing the underlying system complexity in the background, making the system user-friendly despite its operational complexity
Solution Approach 2:
The battery units are designed with universal compatibility features, allowing the same battery design to serve multiple functions and vehicle types. This universality reduces the need for complex vehicle-specific battery systems and enables a shared infrastructure that simplifies overall system complexity through standardization

AI summary
A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. The charging and distribution machines may distribute portable electrical energy storage devices of particular performance characteristics and other attributes based on customer preferences and/or customer profiles. The charging and distribution machines may provide instructions to or otherwise program portable electrical energy storage devices stored within the charging and distribution machines to perform at various levels according to user preferences and user profiles.
