EV Energy Meter with GPS for Charging Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability to differentiate and track energy used for charging electric vehicles from other purposes, restricting owners to charge at designated stations to receive incentive benefits.
Innovation Solution
A device, comprising an energy meter unit with GPS, communication, and data transmission capabilities, tracks energy usage and associates it with charging location, enabling accurate reporting and billing for energy used in charging electric vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electric vehicle owners charge at any location without verification, then charging flexibility is improved, but the ability to verify energy usage for incentive programs deteriorates
Solution Approach 1:
The monitoring device is nested within the electric vehicle's electrical system, integrating multiple functions (energy measurement, GPS location tracking, data storage, and communication) into a single embedded unit that operates as part of the vehicle's existing infrastructure
Solution Approach 2:
The monitoring device acts as an intermediary between the energy source, the vehicle's battery system, and external verification systems, accurately measuring energy flow and providing verified data to enable incentive programs while allowing charging at any location
2Measurement precision
If electric vehicle owners charge at designated stations only, then energy usage verification is improved, but charging flexibility deteriorates
Solution Approach 1:
The monitoring device is designed to work with any energy source type (designated charging stations, home outlets, public infrastructure) rather than being limited to specific infrastructure, providing universal verification capability across diverse charging locations
3Measurement precision
If a monitoring device is installed to track energy charging, then energy usage verification is improved, but device complexity deteriorates
Solution Approach 1:
The monitoring device combines multiple measurement and verification functions (energy metering, GPS location, data logging, communication) into a single integrated unit that interfaces with the vehicle's existing electrical system through standard connections
Solution Approach 2:
The monitoring device automatically performs energy measurement, location tracking, data storage, and verification without requiring user intervention, operating autonomously to reduce complexity of operation
Data Source
AI summary
A energy meter unit for an electric vehicle contains energy measuring circuitry, a GPS unit, a CPU, and memory. The energy meter unit is capable of detecting the amount of energy charged at a specific location and storing that information for later uses, such as with a governmental incentive program.
