The invention discloses a detecting and converting device for electric car AC-DC charging piles. The detecting and converting device comprises a case body, and charging sockets, calibration pulse sockets, a voltmeter L interface, a voltmeter N interface, an ammeter interface and a current clamp ammeter interface arranged on the case body, wherein at least two charging sockets are connected with an L line, an N line, a PE line and a signal line, at least two calibration pulse sockets arranged on the case body are connected through an anode pulse signal line and a cathode pulse signal line, the current clamp ammeter interface is arranged on the L line between the charging sockets and connected with the L line, and the voltmeter L interface and the voltmeter N interface are respectively connected with the L line and the N line. The detecting and converting device realizes connection between a standard meter and a charging load and completes on-site detection, testing, monitoring and selective examination of AC charging piles and DC chargers.
Description
technical field [0001] The invention relates to a verification conversion device for AC and DC charging piles of electric vehicles, which belongs to the technical field of electric energy detection. Background technique [0002] The construction of electric vehicle charging piles and charging stations is gradually carried out in Zhejiang Province and more than 20 large and medium-sized cities across the country. The verification of electric vehicle charging piles related to trade settlement is an urgent problem to be solved by the government's metrology administrative supervision department. However, the development of the verification device for AC and DC charging piles of electric vehicles is still in the state of development and research. [0003] At present, although the charging pile DC electric energy meter verification device and the single-phase wide-range charging pile electric energy metering device in the prior art have solved the goal of verifying the meter inst...
