Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Electric Vehicle Supply Equipment (EVSE) systems have limited capabilities, primarily restricted to charging operations and basic payment functions, and lack the ability to provide location-based services to users, limiting their utility in facilitating access to various services around or away from charging stations.
Innovation Solution
The implementation of a method and apparatus that enables EVSEs to transmit radio frequency (RF) signals containing information for wireless communication devices, allowing users to access services such as payment, local information, and geographical tracking or routing based on their proximity to the EVSE, using RF control circuitry, processors, and memory to facilitate communication and service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If EVSE transmits RF signals with location information to enable location-based services, then service accessibility and user experience are improved, but device complexity and energy consumption increase
Solution Approach 1:
The EVSE is designed to perform multiple functions: traditional charging operations, payment processing, and location-based service transmission via RF signals. By integrating these diverse functions into a single device, the system achieves versatility without requiring separate dedicated devices for each function, thus improving service accessibility while managing device complexity through consolidation
2Adaptability or versatility
If EVSE transmits RF signals with location information to enable location-based services, then service accessibility and user experience are improved, but energy consumption increases
Solution Approach 1:
The EVSE transmits RF signals containing location information periodically rather than continuously. This periodic transmission approach enables location-based services to be accessed when needed while significantly reducing overall energy consumption compared to continuous transmission, thus resolving the contradiction between service accessibility and energy usage
3Adaptability or versatility
If EVSE is equipped with digital processing capabilities and internet connection, then communication capabilities are improved, but device complexity increases
Solution Approach 1:
The patent combines digital processing capabilities, internet connectivity, and RF transmission functionality into an integrated EVSE system. By merging these communication-related functions into a single unified device rather than using separate components, the system achieves enhanced communication capabilities while managing overall device complexity through consolidation and integration

AI summary
Location based services to users of electric vehicles (114) are facilitated. Users that are in possession of a wireless communication device (116) may receive RF signals in the form of beacons (109) transmitted by an EVSE (102). The information contained in the signals may be used to facilitate for the user when the user wishes to take advantage of different services (132,134,136), nearby the EVSE (102) as well as further away from the EVSE (102).
