Title:
POSITIVE AND NEGATIVE ELECTRODES-BASED RELAY DETECTION CIRCUIT, AND DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/082497
Kind Code:
A1
Abstract:
A positive and negative electrodes-based relay detection circuit, and a detection apparatus. The relay detection circuit comprises a power supply circuit, a positive electrode relay detection circuit, a negative electrode relay detection circuit, and an auxiliary detection circuit; the power supply circuit comprises a power source, an electric device, a positive electrode relay, and a negative electrode relay; the positive electrode relay detection circuit comprises a first resistor, a second resistor, a third resistor, and a first voltage sampling end; the negative electrode relay detection circuit comprises a fourth resistor, a fifth resistor, a sixth resistor, and a second voltage sampling end; and the auxiliary detection circuit comprises a seventh resistor, an eighth resistor, and a third voltage sampling end. When detecting the state of the positive electrode relay and the state of the negative electrode relay, a common sampling point voltage is used as detection basis, greatly improving the accuracy and detection efficiency of detection of the positive electrode relay and the negative electrode relay.
