Embodiment 1

[0040]An adaptive calibration method for T-BOX for an electric vehicle, wherein the vehicle-mounted terminal T-BOX1 is respectively connected to a vehicle controller VECU2 and a battery management system BMS3 for signals through a CAN bus, and the vehicle-mounted terminal T-BOX1 communicates with a battery through a wireless network Remote service and management platform 4 signal connection;

[0041] The calibration method includes the following steps:

[0042] The first step is to obtain the VIN code:

[0043] When the vehicle-mounted terminal T-BOX1 is powered on for the first time, the vehicle-mounted terminal T-BOX1 sends a request to the vehicle controller VECU2 to read the VIN code through the CAN bus, and the vehicle controller VECU2 sends a request to the vehicle-mounted terminal T-BOX1 through the CAN bus after receiving the request. VIN code message, vehicle terminal T-BOX1 receives the VIN code message, and judges the integrity of the received VIN code, if the rece...

Abstract

The invention relates to a self-adaptive calibration method of a T-BOX for an electric vehicle. The T-BOX is in signal connection with a VECU and a BMS through a CAN bus, and the T-BOX is in signal connection with a remote service and management platform through a wireless network. The control method comprises the following steps: step 1, obtaining a VIN code, step 2, obtaining battery information, and step 3, packaging and sending. The T-BOX designed by the invention can autonomously receive the VIN code information and the battery information, so that the ex-factory steps of T-BOX loading are simplified, and the application range of the T-BOX is expanded.

Description

technical field [0001] The invention relates to an adaptive calibration method of a T-BOX for an electric vehicle, which is particularly suitable for a vehicle-mounted terminal of an electric vehicle remote service and management system. Background technique [0002] The existing electric vehicle T-BOX has a specific T-BOX for a certain model, and the T-BOX software is calibrated when the vehicle is off-line, or the dedicated T-BOX corresponding to different models is used for the battery information of the vehicle and the vehicle information. VIN code upload. [0003] Due to the national standard, the uploaded data includes: 1. Vehicle information such as VIN code; 2. Power battery information, including the number of single batteries, the number of battery temperature probes, and the corresponding voltage value and probe temperature value of each single unit. Due to different vehicle configurations, this information will change, so there are two solutions for the currentl...
