Scope of Application
 

XL-A822 DC Charging Pile Calibration Device Integrates DC standard meter (0.01 level/0.02 level optional) and DC standard source into one unit, adopting a modular design. The DC standard meter, clock unit, and other standards are detachable for inspection. According to relevant calibration regulations, it can perform initial calibration, subsequent calibration, and in-use inspection of electric vehicle DC charging machine calibrators. Suitable for accuracy testing and calibration of charging equipment testers, establishing a traceability system for charging equipment testers by metrology departments, power departments, and testing institutions, and for charging pile manufacturers requiring factory test calibration of charging equipment testers.

Calibration Items

Main Functions
 

• According to relevant calibration regulations, it can perform initial calibration, subsequent calibration, and in-use inspection of electric vehicle DC charging machine calibrators.
• The DC charging pile calibration device is rated 0.01 level (0.02 level optional), built-in 0.01 level (0.02 level optional) DC standard meter and clock unit, all detachable for easy inspection.
• The device has built-in DC voltage standard source and DC current standard source, supporting superimposed ripple output.
• The device supports two modes: simulated real load detection mode and virtual load detection mode. The simulated real load detection mode can simulate the real load test environment of on-site charging pile detection, including the influence of on-site connections and impedance; the virtual load detection mode has a separate calibration interface and does not include the influence of on-site connections and impedance. Both modes can be switched programmatically or manually, facilitating automatic calibration of the whole machine.
• The device has DC charging gun interface, DC and AC charging socket interfaces, allowing plug-in connection to the charging pile calibrator without complex wiring.
• The device has excellent temperature stability, with core components being military-grade products with temperature coefficients as low as 1PPM.
• The built-in standard power source uses hardware PID technology, with high stability and extremely fast response, response time in milliseconds.
• All modules inside the device communicate and interconnect, controllable via a single RJ45 communication port for easy connection.
• The device is equipped with comprehensive protections including overcurrent, overvoltage, overheating, short circuit, open circuit, and overload protection.
• The device comes with powerful and easy-to-use operation software that can complete the testing of DC charging machine calibrators according to calibration regulations and generate test reports with one click. It can run on industrial control computers or PCs.
