Product Description

TK4850E DC EV Charging Station Testing Device

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.

Key Features

Built-in 8 kW DC Load: A single device can test the off-board charger independently.
Load Expansion: Supports connection to an external high-power resistive load for extensive testing.
Vehicle-as-Load: Supports using new energy vehicles as loads to measure accumulated energy.
Wide Dynamic Range: Technology avoids measurement risks caused by charger output fluctuations.
MS-Level Refresh Speed: Improves measurement accuracy of accumulated electric energy.
High Integration: Combines power measurement module, control guidance circuit, and 8 kW load.
Ripple & Clock Verification: Measures voltage/current ripple and provides real-time clock error testing.
Portable Design: Equipped with retractable pull rods and rollers for easy one-person operation.
Safety Protection: Overvoltage, overcurrent, and emergency stop protection built-in.

Frequently Asked Questions

Q1: What is the maximum testing voltage and current for the TK4850E? The device supports DC voltage measurement from 200V to 1000V and DC current measurement from 1A to 250A.

Q2: Does the device require an external power source for on-site testing? No, it supports three modes: power supply from the charging gun head, built-in lithium battery, or standard 220V mains power, making it highly flexible for field use.

Q3: Can the 8kW built-in load be expanded? Yes, the TK4850E supports load expansion and can be connected to an external high-power resistive load if higher power testing is required.

Q4: How is the device operated during testing? The device is operated via a wireless tablet, allowing for automatic testing, data recording, and even taking photos of the on-site setup.

Q5: Is the TK4850E suitable for ripple measurement? Yes, it includes built-in functions for measuring both voltage and current ripple with high accuracy.

Q6: Is the device portable enough for a single technician? Absolutely. Despite its integrated 8kW load, it weighs approximately 22kg and is equipped with retractable pull rods and rollers for easy transport.
