Frequently asked questions

Which Hongyi resistors are used in EV charging stations?
EV charging applications typically combine: high-power aluminum-housed resistors for pre-charge / discharge circuits (5–500 W), wirewound current-sensing resistors with low TCR (≤±50 ppm/°C), and high-voltage resistors for HV battery testing. We've shipped resistors into all 7 of the top-10 Chinese EV charger OEMs.
Are Hongyi resistors qualified for automotive use?
Our facility is IATF 16949 certified, and our automotive-grade product lines are tested per AEC-Q200 (passive component stress test). The HRA-AT series (high-power aluminum housed) and select wirewound and cement product lines have full automotive qualification documentation available on request.
Can Hongyi supply resistor cabinets for industrial braking?
Yes. We design and build resistor boxes / cabinets from 5 kW to 500 kW for VFD braking, motor regen, dynamic braking and energy dissipation. Standard configurations include natural-cooling, forced-air and water-cooled enclosures with IP00 to IP65 rating. Custom dimensions, terminal positions and over-temperature protection circuits are standard options.
Are Hongyi resistors used in renewable-energy systems?
Yes — extensively. Our resistors ship into solar inverters (DC-link discharge, MPPT current sensing), wind power converters (crowbar resistors, DC-link braking), energy storage PCS (insulation monitoring, pre-charge), and EV charging infrastructure. The high-power, high-pulse and high-voltage product families are most relevant to renewable applications.
Can you recommend a resistor for my specific application?
Absolutely. Send us your application context (load type, peak/continuous power, voltage, ambient temperature, mounting constraints) via the inquiry form, and an application engineer will recommend a model — including links to datasheets and free samples — within 4 business hours. We don't charge for selection consultations.
