ELECTRIC VEHICLE CHARGING WITH EXTENDED REALITY

Smart overview of the Invention

The patent application discusses a system that integrates extended reality (XR) technology to assist users in charging electric vehicles (EVs) using electric vehicle service equipment (EVSE). A computer system with a processor and memory executes a large-language model (LLM) to generate handling operations. These operations guide users on how to handle EVSE components during the charging process. The XR device displays these instructions overlaid on the EVSE, highlighting relevant components to facilitate the charging process.

Background

Charging electric vehicles involves different levels of chargers, such as Level 1, Level 2, and Direct Current Fast Chargers (DCFC). Each type varies in voltage and charging speed, with Level 1 being the slowest and DCFC the fastest. The complexity of these systems necessitates clear guidance for users, especially those unfamiliar with EVSE or facing complex troubleshooting scenarios. The proposed system aims to address these challenges by providing intuitive, real-time instructions through XR technology.

Detailed Description

The system is designed to aid various users, including EV operators, repair technicians, and call-center technicians, by providing tailored instructions based on their roles. The XR device can operate in both augmented reality (AR) and virtual reality (VR) modes, depending on the user's location relative to the EVSE. This flexibility allows users to receive guidance whether they are at the charging station or remotely located. The LLM adapts instructions to specific scenarios, such as fault detection, enhancing the user experience and success rate in charging operations.

Examples and Applications

In practical scenarios, the system can manage interruptions during charging by generating responsive handling operations. It can also determine user roles, such as EV operator or repair technician, and customize instructions accordingly. For instance, repair technicians might receive guidance on internal EVSE components inaccessible to regular users. Additionally, the system can process payment data and suggest alternative EVSEs if faults occur, improving the overall charging experience.

Technical Implementation

The system comprises a vehicle computer, remote computer, or XR device that tracks the charging sequence and executes the LLM. The XR device displays handling operations overlaid on the EVSE, highlighting necessary components. The vehicle computer communicates via a network, interfacing with sensors, user interfaces, and other components to manage the charging process. This setup ensures seamless integration of XR technology with existing EV infrastructure, enhancing user interaction and operational efficiency.
