With the rapid development of the new energy vehicle industry, AC charging piles, as core infrastructure of the new energy energy supplement system, have attracted widespread industry attention in terms of product safety, stability and compatibility. Professional and accurate testing equipment is indispensable for the R&D iteration, factory quality inspection, type certification and laboratory calibration of charging piles.
Developed by Ningbo Zhimao, the EVA AC Charging Pile Laboratory Comprehensive Test System adopts a mature integrated load bank solution. It solves the drawbacks of single function and limited working condition simulation of traditional testing equipment, and serves as a core solution for full-item laboratory testing of charging piles.
Most traditional charging pile testing equipment adopts split design, with independent load devices, testing instruments and control systems. It features complicated wiring, poor data synchronization and single test working conditions, which not only reduces laboratory testing efficiency, but also causes deviations in test data and fails to meet the high-precision requirements of national standard testing.
In contrast, the EVA AC charging pile test system adopts an integrated load bank structure. It highly integrates programmable AC load, power quality analysis module, working condition simulation unit, data acquisition and control system. Featuring compact structure and neat layout, it effectively simplifies laboratory testing procedures and adapts to various standardized laboratory testing scenarios.
In terms of core performance, this integrated test system is capable of full working condition simulation and testing. It can accurately simulate various extreme operating conditions of charging piles including no-load, full-load, overload, under-voltage and over-voltage, and support steady-state and dynamic load switching tests, fully covering national standard testing items such as electrical performance, safety performance and stability of AC charging piles.
Equipped with high-precision sampling chips, the system realizes high-accuracy measurement of power parameters. It accurately collects core data including voltage, current, power, power factor and harmonic waves, and generates visual test reports in real time, ensuring the authenticity, accuracy and traceability of test data, which fully complies with strict standards for charging pile type tests, R&D verification and factory sampling inspection.
Meanwhile, the equipment boasts strong compatibility and practicality, which is applicable to mainstream national-standard AC charging piles and meets the testing demands of charging piles with different power ratings and models. The intelligent control system supports automatic test process setting. It enables one-click start of batch test items and automatically completes data recording, analysis and judgment, greatly reducing manual operation and improving laboratory testing efficiency.
Built-in protection mechanisms realize automatic protection against over-current, over-voltage and overheating, avoiding equipment damage and potential safety hazards during tests and ensuring long-term stable operation.
Compared with traditional split-type testing equipment, the EVA integrated load bank test system has outstanding advantages of integration, high precision, intelligence and strong compatibility, perfectly meeting the full-scenario testing demands of R&D laboratories of charging pile manufacturers, third-party testing institutions and quality inspection institutes.
This solution not only makes up for many deficiencies of traditional testing equipment, but also boosts the standardized and high-quality development of the charging pile industry, providing reliable technical and equipment support for quality control and technical upgrading of AC charging piles.
