Battery pack dormancy detection device, method and vehicle

Abstract

The present invention provides a battery pack dormancy detection device, method and vehicle, wherein the detection device includes: a high level signal input terminal and a low level signal input terminal for inputting high and low level communication signals; the first communication resistance, the high-level signal input end is grounded through the first communication resistance; the second communication resistance, the low-level signal input end is grounded through the second communication resistance; the detection module is used to communicate according to the high-level communication signal and the low-level The communication signal generates a detection signal, and outputs the detection signal; the controller is connected to the output terminal of the detection module, and is used to determine whether the battery pack enters a dormant state according to the detection signal. The battery pack dormancy detecting device, method, and vehicle of the present invention can detect whether the battery pack enters a dormant state, avoiding the problem that the battery pack is dormant so that the vehicle cannot be started after it goes off-line, and improves the production detection efficiency and the reliability of the entire vehicle.

Description

technical field [0001] The invention relates to the technical field of electronic detection, in particular to a detection device, method and vehicle for battery pack dormancy. Background technique [0002] With the development of science and technology and the progress of society, consumers have higher and higher requirements for the intelligence of vehicles, which brings opportunities and challenges to electronic control technology. [0003] When the battery pack is ignited and the charging signal is turned off, the battery management system of the battery pack enters the sleep mode, shutting down unnecessary communication and power supply, so that the power consumption of the battery pack management system (Battery Management System, referred to as BMS) is in the minimum mode, which is the power consumption of the battery pack. Pack dormancy; battery pack dormancy will cause the battery pack to fail to clear the history and current faults. In the production of complete aut...

Problems solved by technology

[0003] When the battery pack is ignited and the charging signal is turned off, the battery management system of the battery pack enters the sleep mode, shutting down unnecessary communication and power supply, so that the power consumption of the battery pack management system (Battery Management System, referred to as BMS) is in the minimum mode, which is the power consumption of the battery pack. Pack dormancy; battery pack dormancy will cause the battery pack to fail to clear the history and current faults. In the production of automobiles, serious faults in the battery system are prone to occur.
