EV Battery Replacement Scheduling to Avoid Charging Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid increase in electric vehicle charging demand leads to peak power surges, voltage variations, increased losses, and potential power outages, while conventional charging methods are time-consuming, causing inefficiencies in electric vehicle adoption.
Innovation Solution
A battery replacement service system that determines a target battery for replacement based on driving data, timing, and location, providing fully charged batteries without charging time, with options for first-type and second-type services considering user battery value changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional charging methods are used, then the battery can be recharged, but it takes a considerable amount of time
Solution Approach 1:
The patent extracts the battery from the charging process entirely by removing it from the vehicle and replacing it with a pre-charged battery at a service station. This eliminates the charging time bottleneck by separating the battery replacement function from the charging function, allowing vehicles to be quickly serviced without waiting for charging.
Solution Approach 2:
The system performs preliminary charging actions at a centralized service station before the battery is needed. Batteries are charged in advance at the service station, so when a vehicle needs battery replacement, it receives a fully charged battery immediately without requiring on-site charging time.
2Quantity of substance
If multiple electric vehicles are simultaneously charged, then the charging demand is met, but peak power increases causing voltage variations and power outages
Solution Approach 1:
The patent segments the charging process into two separate locations: centralized charging at the service station and immediate replacement at the vehicle. This distributes the power demand over time and location, preventing peak power surges at multiple charging stations simultaneously while still meeting the charging needs of multiple vehicles.
Solution Approach 2:
The service station acts as an intermediary between the power grid and the vehicles. It buffers the power demand by charging batteries centrally and distributing them to vehicles as needed, smoothing out peak power demands and preventing voltage variations and outages.
3Loss of time
If fast charging is used, then charging time is reduced, but it still takes a lot of time when there are many vehicles to charge
Solution Approach 1:
The system enables self-service battery replacement where vehicles can quickly exchange batteries at the service station without requiring lengthy charging processes. The battery replacement process is streamlined and rapid, allowing multiple vehicles to be serviced in sequence without the time constraints of charging.
