Features
• With a built-in 8 kW DC load, a single device can test the off-board charger. • Supports load expansion and can be connected to an external high-power resistive load for testing. • It supports using new energy vehicles as loads to measure accumulated electric energy during the entire actual charging process, and supports the verification of Tesla chargers. • Wide dynamic range measurement technology avoids measurement risks caused by charger output fluctuations. • The ms-level electric energy refresh speed reduces the error caused by the asynchronous accumulation of electric energy between chargers and standard instruments, and improves the measurement accuracy of accumulated electric energy. • Integration: A single device integrates the power measurement module, charging control guidance circuit, 8 kW DC load, etc., and a single device can complete the working error verification of off-board chargers, effectively improving efficiency. • Fixed power: The system can preset the charging power and automatically control the start and stop of the charger. • Ripple measurement: It has the function of measuring voltage and current ripple. • Clock verification function: real-time clock display, which can complete the clock time error test of the charging pile. • Temperature probe: A wired temperature probe is standard, which can complete on-site temperature measurement. • Bluetooth temperature and humidity meter (optional accessory): An optional Bluetooth temperature and humidity meter can be connected to a tablet via Bluetooth to complete on-site temperature and humidity measurements and automatically record data. • Traceable calibration: with dedicated calibration terminals to facilitate instrument calibration. • Wireless tablet operation allows you to save on-site information by taking photos and complete automatic testing. • With its own display screen, the working error test can be completed directly on the lower computer display screen. • High reliability: The load uses high-reliability alloy resistors, which support 8 hours of continuous full-load operation. The equipment will not experience abnormalities such as overheating, and at the same time ensure accurate measurement. • Safety protection: equipped with overvoltage protection, overcurrent protection, abnormal wind speed protection, and emergency stop switch; • Portable: With the built-in load, the weight and volume of the equipment are minimized, and it is equipped with special retractable pull rods and rollers, so a single person can easily complete on-site inspections. • Power supply mode: supports three modes: mains input, gun head power supply and built-in lithium battery power supply. |
Testing Items
• Working error: A single device can complete the working error test of charger. • Clock verification: It has time synchronization function, real-time clock display, and clock time error test of the charger. |
