ST-9980A DC Charging Pile Comprehensive Tester, developed by Saiter, is a professional instrument designed to perform interoperability testing and communication protocol conformance verification in accordance with Chinese national standards. It is specifically used for third-party on-site testing and product acceptance inspection of off-board conductive chargers for electric vehicles. The tester is suitable for R&D activities by charger manufacturers and acceptance checks by third-party testing organizations. It is also widely used by charging facility producers for preliminary development, debugging, factory testing, and on-site acceptance of off-board conductive chargers.
Supports interoperability testing, communication protocol conformance validation, BMS simulation, and optional metrological verification.
Offers multiple communication interfaces including LAN, RS232, and WIFI. Equipped with a built-in WIFI hotspot for remote wireless operation, facilitating convenient on-site usage.
Integrates a high-precision Hall sensor (standard accuracy of 0.1%; optional 0.05%) with a current range of 10–300A. Supports multiple verification methods through voltage/current test interfaces. Features a high-power output load gun holder for quick and efficient connection to external load equipment.
Accurately simulates the charging process and various fault conditions. Includes an auxiliary power supply system to ensure comprehensive testing, eliminating issues such as incomplete test coverage, operational inconvenience, time-consuming battery charging-discharging cycles, and reduced battery lifespan.
