Abstract

The present invention discloses an insulation detection device with integrated multiple functions. The device comprises: a main controller, a power circuit, a high-voltage switching unit, an insulation detection circuit, a voltage and current sampling circuit, a metering chip, a built-in bleeder resistor, a bleeder control circuit, a LCD / LED display, a clock circuit, an EEPROM, a key, a battery circuit, a 485 communication circuit and a CAN communication circuit. A direct current bus between a charging module and a main relay of a charging pile and a PE line are accessed into the high-voltageswitching unit, and insulation state detection is performed by the insulation detection circuit; and the direct current bus of the charging pile after outputting the main relay is accessed into the voltage and current sampling circuit, and electric energy metering, battery voltage measurement and charging current measurement can be performed by employing the metering chip. The device provided by the invention can solve the problems that the internal structure of the charging pile is complex and the cost is high, so that the circuit integrates a direct current metering function, a bleeder function, a battery voltage detection function and an insulation detection function, and a battery optimization performance is completed.

Description

technical field [0001] The invention relates to the technical field of test and measurement, in particular to an integrated multifunctional insulation detection device. Background technique [0002] With the rapid promotion of electric vehicles, the demand for DC charging piles has grown rapidly. According to national standards, DC charging piles must have insulation detection functions, discharge functions, battery voltage detection functions, and DC energy metering functions. The insulation detection function is used to detect the insulation state of the DC bus to ensure the safe and reliable use of the DC charging pile. The discharge function is to discharge the residual energy of the internal output capacitor after the charging module stops outputting to ensure the safety of the charging pile. The battery voltage detection function is to detect the battery voltage in real time, and provide detection basis for battery reverse connection, overvoltage and undervoltage prot...
