Introduction to Hopetech
Hopetech is a professional manufacturer of electrical safety test instruments, with decades of experience in R&D and production for the new energy, electronics and power industries. We provide integrated, reliable test solutions for manufacturers of new energy vehicle motor and electronic control systems. Our full lineup of test equipment covers the complete production and verification process, helping customers meet international safety standards, improve product reliability and reduce testing failure rates.
The manufacturing of new energy vehicle motors and electronic control systems requires multi-dimensional safety and performance verification. Our test instruments do not work in isolation; they form a coordinated testing ecosystem.
✅ CHT9922 / HP9985A/B Integrated Hipot Tester
It acts as the “first line inspector” for small high-voltage parts like DC-DC converters. It completes 3-in-1 tests of withstand voltage, insulation and grounding quickly. With arc detection and 4-wire low resistance measurement, and built-in PLC interface, it can seamlessly connect to your automatic production line to catch hidden dangers of components at the early stage.
✅ CHT9951A/B High Voltage Hipot Tester
It is the “extreme condition lab inspector”. It supports up to DC15kV high voltage output, insulation resistance up to 999GΩ and 9-level arc detection. It simulates the harshest operating environment to do withstand voltage breakdown test and insulation aging verification, checking whether your motor and electronic control products can remain safe under extreme high voltage.
✅ CHT9931A High Current Ground Continuity Tester
It serves as the “safety guardian of the housing”. It outputs adjustable DC current from 10A to 100A, and measures grounding resistance from 0.1μΩ to 600mΩ. It verifies the reliability of the motor and ECU shell grounding, to guarantee the high-voltage leakage protection function meets the mandatory standards of new energy vehicles.
For new energy vehicle motor and electronic control system manufacturers, Hopetech provides a complete set of coordinated safety test solutions. From component batch inspection, high voltage reliability aging test to finished product grounding compliance test, our instruments work together to discover insulation defects, high voltage breakdown risks and grounding failures in advance. This helps you pass standard audits, improve product yield and build reliable high-voltage electrical systems.
