Communication detection system of communication module

Abstract

The invention discloses a communication detection system of a communication module. The system comprises a startup power supply, a BMS, a communication module, a monitoring platform and a display unit, wherein the startup power supply is connected to the BMS, the communication module and the display unit; the BMS is connected to the display unit; the communication module communicates with the BMSand the monitoring platform; when the startup power supply is turned on, the startup power supply supplies power to the BMS, the communication module and the display unit; the BMS transmits a detection signal to the communication module, and if the BMS does not receive a feedback signal sent by the monitoring platform within a first preset time, the BMS transmits an alarm signal to the display unit, and the display unit displays the alarm signal to inform a user that the communication module has a communication failure. According to the communication detection system of the communication module disclosed by the invention, whether the communication module has the communication failure can be detected.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a communication detection system of a communication module. 【Background technique】 [0002] With the continuous development of the new energy industry, there are more and more types of new energy electric vehicles. A large number of batteries are installed on new energy electric vehicles such as pure electric buses, pure electric buses, pure electric logistics vehicles, and pure electric supplementary vehicles. The safety of batteries is crucial to the safety of the entire vehicle. At present, the battery status information is usually sent to the monitoring background by the BMS (BATTERYMANAGEMENT SYSTEM, battery management system) through the communication module, but there is a lack of detection of whether the communication module is communicating normally. If the communication module communication is abnormal, the battery status information cannot be sent To the m...

At present, the battery status information is usually sent by the BMS (BATTERYMANAGEMENT SYSTEM, battery management system) to the monitoring background through the communication module, but there is a lack of detection of whether the communication module is communicating normally. If the communication module communication is abnormal, the battery status information cannot be sent. to the monitoring background, and at the same time the battery fails, the background monitoring personnel cannot know the fault information of the electric vehicle, and cannot eliminate the fault of the electric vehicle in time, which will affect the safe use of the electric vehicle
