10kA Short-Circuit Withstand Current Tester | IEC 62196-1 Compliant For EV Testing

Product Overview

Short-Circuit Withstand Current Tester is a dedicated device designed for performing short-circuit withstand current tests on electrical equipment such as EV charging guns, circuit breakers, distribution transformers, ring main units, cable distribution boxes, and connectors. It fully complies with the short-circuit current withstand capability verification test requirements specified in the relevant clauses of IEC 62196-1:2025.

The system features an industrial all-in-one computer for display and parameter setting, a PLC controller for process control, and a data acquisition card for waveform measurement. It delivers a test current of up to 10 kA.

The AC power supply adopts a high-power multi-magnetic-circuit AC power source with an adaptive current control loop. The voltage test mode uses isolated voltage superposition, supporting a maximum test voltage of 1000 V.

The equipment offers user-friendly operation, quick product installation, automatic testing, automatic judgment functions, and high intelligence and reliability.

Technical Features

Equipped with an industrial all-in-one computer for parameter display and real-time waveform visualization, offering a clear and intuitive interface.
High-speed data acquisition enables real-time monitoring of current waveforms with microsecond-level (μs) time resolution.
The current source adopts a multi-magnetic-circuit AC power supply with digital control, delivering high accuracy and excellent stability.
The voltage uses an isolated design, creating a 1000V potential difference with the equipment housing (ground terminal) while reducing power consumption.
Supports testing of overload currents at 2.0/2.5/3.0/3.5/4.0/5.0/8.0/10 times the rated current (i.e., 50~10000A).
Compatible with testing of various device specifications.
Capable of measuring and recording the relationship between current and time.
Features comprehensive protection functions including over-voltage and over-current protection, which automatically cut off output and trigger audible-visual alarms when triggered.
Records real-time test data for easy review and traceability.

Why do EV charging connectors need 10kA high current testing?

During normal EV charging operations, connectors are designed to handle steady-state currents. However, in the event of a short-circuit fault in the vehicle, charging station, or power grid, EV charging connectors may be exposed to extremely high transient currents, often reaching several kiloamperes. A 10kA short-time withstand current test is required to verify that the connector can withstand the thermal and mechanical stress of such a fault without damage, deformation, melting, or safety hazards such as fire or electrical shock.

This test is not only essential to meet the IEC 62196-1:2025 certification requirements for EV connectors, but also to ensure long-term product safety and reliability in real-world applications. Without passing this test, there is a significant risk of connector failure during a fault, which could lead to equipment damage, system shutdown, or even safety incidents. By simulating the worst-case short-circuit conditions, manufacturers can validate the design, materials, and manufacturing quality of their charging guns before they reach the market.
