Abstract

The invention provides a vehicle anti-false-alarm insulation detection circuit, which comprises a central control module, a driving module, a signal detection module and a switching compensation module. According to the technical scheme, the switching compensation module is additionally arranged in the vehicle anti-false-alarm insulation detection circuit, the measurement precision is improved byadditionally arranging a compensation capacitor, the switching compensation module is used for increasing the capacitance impedance value of the vehicle anti-false-alarm insulation detection circuit,insulation misinformation is prevented, and the detection precision of the signal detection module is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vehicle false alarm prevention insulation detection circuit. Background technique [0002] In new energy vehicles, insulation detection is one of the functions of the battery controller. The purpose is to detect the resistance of the insulation resistance between the high voltage and low voltage of the vehicle. If the resistance of the insulation resistance is too low, there will be a risk of electric shock. However, in the detection system of the automobile, because the capacitance in the detection circuit is different due to the medium, the capacitance value of the capacitance changes, so that the automobile detection circuit detects the Y capacitance of the whole vehicle (the Y capacitance refers to the high-voltage ground wire and the low-voltage ground wire). When the capacitance between them), the capacitance value of the Y capacitor of the whole vehicle changes...
