Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Example of transmission system for off-board charger data:

[0037] The transmission system includes off-board charger, battery management system, vehicle CAN bus, on-board remote monitoring terminal, cloud server and vehicle monitoring platform. figure 1 The transmission process of off-board charger data and vehicle data is given, in which the off-board charger sends the off-board charger data to the battery management system BMS through information interaction with the battery management system (BMS), and the BMS will receive The off-board charger data is cached locally, and the cached off-board charger data is sent to the CAN bus of the vehicle. In addition, the vehicle data is also sent to the CAN bus of the vehicle after the various parts inside the vehicle are powered on. The on-board remote monitoring terminal collects off-board charger data a...

Abstract

The invention relates to a non-vehicle-mounted charger data transmission method, system, a BMS (battery management system) and a monitoring terminal. The non-vehicle-mounted charger data transmissionsystem comprises a non-vehicle-mounted charger, a battery management system, a full vehicle CAN bus, a vehicle-mounted remote monitoring terminal and a cloud server. Data of the non-vehicle-mounted charger is sent to the battery management system by the non-vehicle-mounted charger; the data of the non-vehicle-mounted charger sent by the non-vehicle-mounted charger is received and cached by the battery management system, and the data of the non-vehicle-mounted charger is sent to the full vehicle CAN bus; the cached charger data is transmitted to the cloud server by the vehicle-mounted remote monitoring terminal through wireless network; and the charger data of the vehicle-mounted remote monitoring terminal is collected by the cloud server in real time, and response messages are sent to thevehicle-mounted remote monitoring terminal by the cloud server. According to the non-vehicle-mounted charger data transmission method, system, the BMS (battery management system) and the monitoring terminal, a reliable guarantee for realizing remote monitoring of the data of the non-vehicle-mounted charger and real-time analysis of charging situations is provided.

Description

technical field [0001] The invention relates to an off-vehicle charger data transmission method, system, BMS and monitoring terminal, belonging to the technical field of electric vehicle charging. Background technique [0002] At present, there are two transmission methods for remote monitoring of charger data. The first is that the remote monitoring terminal of the charger transmits the data of the charger to the charging monitoring platform through the wireless network. Although this method can realize remote monitoring of the data of the charger, due to The mutual independence of the charging monitoring platform and the vehicle monitoring platform, the integration of the charger data and the vehicle data can only be through the data transmission between the platforms, due to the multiple transfers of the charger data, some data may be lost or delayed, real-time And the reliability is not high, and it does not have the value of simultaneous analysis of vehicle data and cha...
