Product Description
TK4830 Portable Tester for EV DC/AC Charging Station
1. Summary
TK4830 is an AC and DC integrated charging station calibration device. The accuracy level of AC and DC power measurement of the device reaches Class 0.05. It can complete the working error and clock time error test of AC and DC charging stations.
The device supports European standard CCS2 DC charging interface, European standard Mennekes (Type2) AC charging interface and Japanese standard CHAdeMO DC charging interface. The device can use new energy vehicles as loads or use resistive loads to test. The equipment combines wide dynamic range measurement technology, ms-level high-speed refresh of electric energy and other technologies to achieve accurate measurement of accumulated electric energy throughout the charging process. Compared with the traditional steady-state measurement of preset calibration points, it more truly reflects the performance of charging station.
2. Verification Abilit
1. Working error: The working error test can be completed in real time during the charging process through the pulse method or the accumulated electric energy method.
Test Method 1: Test with new energy vehicles as load
Test Method 2: Test with programmable resistive load as load
Test Method 2: Test with programmable resistive load as load2. Clock verification: It has time synchronization function, real-time clock display, and clock time error test of the charger.
