BMS data monitoring device for electric vehicle charging pile

Abstract

The invention discloses a BMS data monitoring device for an electric vehicle charging pile, and relates to the electric vehicle charging pile. The BMS data monitoring device comprises a controller, aCAN interface module, a storage module, a wireless communication module and a power supply module, wherein the CAN interface module is connected with a CAN bus between an electric vehicle BMS and thecharging pile; the controller monitors standard message transmitted by CAN between the vehicle-mounted BMS and the charging pile through the CAN interface module, charging state parameters of a battery are acquired in real time for analysis, whether the battery is over-temperature or over-voltage is judged when the battery is charged, the state information including the charging parameters and thefault information is pushed into a cloud management platform through the wireless communication module, and remote management and maintenance are performed by the cloud management platform; and the wireless communication module is a WIFI module. According to the BMS data monitoring device, the CAN bus interface is directly accessed to monitor the standard message transmitted by the CAN between the vehicle-mounted BMS and the charging pile, so that abnormal information during charging of an electric vehicle is obtained.

Description

technical field [0001] The invention relates to the field of charging piles for electric vehicles, in particular to a BMS data monitoring device for charging piles for electric vehicles. Background technique [0002] At present, the wide application of electric vehicles has spawned a large number of various types of electric vehicle charging piles. Although the brands and structures of charging piles are different, the data and information exchange between charging piles and cars are similar. However, due to various The reason is that various charging piles may have abnormal charging during the charging process, and these faults can be obtained from the communication between the charging pile and the car. However, if there is a problem with the charging pile and the car charging in the existing device, only The technician can go to the site and connect the charging pile with special tools to check and analyze the cause of the fault, and because the fault may occur sporadical...

[0002] At present, the wide application of electric vehicles has spawned a large number of various types of electric vehicle charging piles. Although the brands and structures of charging piles are different, the data and information exchange between charging piles and cars are similar. However, due to various The reason is that various charging piles may have abnormal charging during the charging process, and these faults can be obtained from the communication between the charging pile and the car. However, if there is a problem with the charging pile and the car charging in the existing device, only The technician can go to the site and connect the charging pile with a special tool to check and analyze the cause of the fault, and because of the occasional phenomenon of the fault, even if the technician debugs the equipment on site, it may not be possible to reproduce the cause of the fault and solve the problem

[0003] In addition, the existing data collection devices only have the function of collection and do not have the function of data analysis, which requires specialized technical personnel to analyze the corresponding data in order to know the meaning of the data
