The DC Portable Charging Testing System is a field-focused charging pile detection device under the intelligent equipment product portfolio, built for on-site testing and functional verification of DC charging piles. Featuring a compact structure and lightweight build, the system supports operation without AC auxiliary power supply under national standard charging scenarios, addressing the common challenge of limited power access in outdoor and field work environments. It serves commercial users and industrial clients including charging pile installation teams, operation and maintenance service providers, and new energy vehicle testing institutions, covering use cases in on-site installation and debugging, functional verification, after-sales operation and maintenance, as well as online debugging and offline testing. The device integrates parameter detection, communication simulation, and fault testing capabilities, delivering a complete on-site testing solution for the full lifecycle of DC charging piles.
During the on-site deployment of DC charging piles, construction sites often lack stable AC power access, which slows down commissioning progress. This test system supports self-power supply directly through the charging pile under national standard protocols, allowing technicians to complete parameter calibration, communication matching, and basic function verification immediately after the charging pile is installed, without relying on external power grids. This shortens the on-site commissioning cycle and reduces pre-construction preparation work for deployment teams.
For charging pile operation platforms and maintenance service providers, on-site fault diagnosis is a core part of daily business operations. This portable test system can be transported to various charging station locations to conduct real-time detection of charging voltage, current, and communication status, simulate fault scenarios to verify the protection function of charging piles, and locate fault points efficiently. It also supports test data recording, which facilitates subsequent problem tracing and work report generation for maintenance teams, reducing the frequency of component disassembly and return-to-factory maintenance and lowering station operation costs.
In laboratory and production scenarios, the test system can be used for offline function testing of charging pile products before delivery, verifying whether the charging logic, BMS communication, and protection mechanisms meet corresponding standard requirements. It also supports message control and VIN code charging testing, helping manufacturers complete pre-delivery quality inspection and compliance verification, and reducing the risk of non-conforming products entering the market for commercial procurement.
Under the national standard DC charging protocol, the system can realize self-power supply directly through the charging pile, with no need for external AC power supply. It also supports access to 220VAC ± 20% power supply, adapting to both field environments without grid power and indoor laboratory scenarios, providing flexible power supply options for different testing demands.
The system is equipped with charging voltage and current detection functions, covering a DC voltage range of 0-1000V and a DC current range of 0-250A, with an auxiliary power supply range of 0-30V DC. It supports BMS communication simulation and automatic charging test processes, which can complete the full charging flow test automatically without manual step-by-step operation, improving overall testing efficiency.
In addition to basic parameter detection, the system supports VIN code charging testing, fault protection testing, and message control functions. It can simulate various fault scenarios to verify the protection response of charging piles, and realize customized testing processes through message control. These functions cover most testing items required in daily operation and quality inspection, reducing the need for additional testing tools.
The device adopts mainstream communication protocols for charging piles, compatible with CAN2.0B and PLC communication modes, and supports insulation simulation of 300K/33K. It can match the communication logic of charging piles from different manufacturers, ensuring stable data interaction during testing and reducing adaptation costs for users.
