TK4850E DC EV Charging Station Testing Device

TK4850E DC EV Charging Station Testing Device

1. Summary

TK4850 series is a series of high-efficiency testing instruments specially developed to address the problems of complex wiring, difficult handling, low testing efficiency, and high cost during the on-site testing of existing off-board chargers.

TK4850E is one of the all-in-one portable instruments specially designed for on-site testing of off-board chargers of electric vehicles. The instrument integrates a small DC load, supports load expansion, and supports using new energy vehicles as loads. The instrument is operated through a wireless tablet. A single device can complete the working error and clock time error test of the off-board chargers. It is easy to carry and a single person can easily complete the on-site verification of the off-board chargers.

2. 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.
