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. Key Features 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.
