Abstract

The invention discloses an automatic detection module for under-voltage current limiting of an electric vehicle controller and a method thereof. The electric vehicle controller comprises a driving module and a driving control module for controlling the driving module to operate. The automatic detection module comprises an under-voltage current-limiting comparison module. The driving module is connected with the under-voltage current-limiting comparison module through a first communication connection to send voltage and / or the current actual value to the under-voltage current-limiting comparison module. The under-voltage current-limiting comparison module is connected with the driving control module through a second communication connection to send voltage and / or current proportion error values to the driving control module. The output end of the driving control module outputs voltage and / or current value adjusting instruction. The detection efficiency and detection precision are high.Automatic accurate adjustment and control of voltage and / or current are realized. The automatic detection module is simple, and the automatic detection method is simple and convenient.

Description

technical field [0001] The invention relates to the field of electric vehicle controllers, in particular to an automatic detection module for undervoltage and current limiting of the electric vehicle controller, and also relates to an automatic detection method applied by the automatic detection module. Background technique [0002] The voltage and current values ​​of the electric vehicle controller are the core control parameters, and the accuracy of its data output is an important factor that directly determines the accuracy of the electric vehicle controller. Therefore, it is necessary to ensure the accuracy of the voltage and current values ​​of the electric vehicle controller. In the prior art, the voltage and current value of the electric vehicle controller is usually manually detected by means of detection tools. When the voltage and / or current value of the electric vehicle controller is found to deviate from the set value (usually called undervoltage current limiting)...
