ST-HCDC-HPC
High-Power DC EV Charger Comprehensive Tester
Portable high-power DC charger test system for laboratory, production and field-service validation, with GB/T protocol analysis, BMS simulation, metering verification and external-load testing.
Product Overview
High-Power DC EV Charger Comprehensive Tester
ST-HCDC-HPC is a third-party field test system for non-vehicle conductive EV chargers. Built around GB/T 27930-2015, GB/T 34658-2017 and GB/T 34657.1-2017, it replaces test vehicles for repeatable charger validation, avoiding incomplete coverage, battery wear from repeated charging and potential vehicle damage caused by charger faults. The system supports R&D debugging, metering verification and end-of-line testing for charger manufacturers, laboratories and charging facilities.
Key Features
Designed for reliable EV charger validation.
- 01Built-in battery-voltage simulation from DC 0 to 1100 V continuously adjustable, with a 20 mA maximum output, R4 resistance simulation and U2 pull-up-voltage simulation at two test points.
- 02Built-in 0.1% high-precision Hall current transformer covering 10-1000 A, with both voltage-type and current-type test interfaces for multiple calibration methods.
- 03PC software exports and parses test messages, monitors charger data in real time, supports abnormal-state diagnosis and generates GB/T 34658-2017 protocol conformance reports.
- 04Simulates BMS-to-charger communication across handshake, parameter configuration, charging and charge-completion stages. Optional BMS communication and high-speed waveform acquisition modules support plug-in testing.
- 05Eight selectable resistance levels provide insulation-fault simulation for insulation-monitoring function tests.
- 06External high-power load terminals make it possible to connect a separate load for partial NBT 33008.1-2018 load-test items. The tester has no built-in load and supports an external load up to 250 A.
- 07Modular, easy to integrate and suitable for field use, with a protective design and total weight no greater than 25 kg.
