AI Technical Summary

Technical Problem

Existing charging piles have long startup times due to multiple switching of power supply modules and cumbersome national standard message interactions, which affects user experience and increases energy consumption.

Method used

The vehicle battery voltage is obtained directly using a proprietary protocol, simplifying data verification and security testing. The auxiliary power is only turned on and the specified protocol is used after the vehicle identity authentication is passed, avoiding multiple power module switching.

Benefits of technology

Significantly reduces charging start-up time to 7.5-8 seconds, improves user experience and reduces power module losses, and is compatible with existing charging infrastructure.

Abstract

The application provides a charging pile quick start charging method and system based on a private protocol, which comprises the following steps: after the charging pile is connected with a vehicle, the charging pile sends a charging pile request message to the vehicle through a private protocol; the charging pile receives a vehicle response message replied by the vehicle through the private protocol, and the vehicle response message at least comprises a vehicle battery voltage; the charging pile performs data verification on the vehicle response message of the vehicle identification code, and after the data verification is passed: starting vehicle identity authentication, turning on a power module for safety detection, and the test voltage used for the safety detection is the vehicle battery voltage reduced by a preset voltage value; after the vehicle identity authentication is passed, the charging pile turns on an auxiliary power supply, and performs message interaction with the vehicle through a designated protocol; after the message interaction is completed and the safety detection is passed, the charging pile charges the vehicle. The application shortens the charging start time of the charging pile and improves the user experience.
