Test Solution for NEV Body & Chassis Structure, On-board Electronics and Auxiliary Systems

Test Solution for NEV Body & Chassis Structure, On-board Electronics and Auxiliary Systems

Changzhou Hopetech Electronic Technology Co., Ltd., founded in 2009, is a national-level high-tech manufacturer with full in-house capabilities for hardware-and-software R&D and complete-machine manufacturing. The company participates in the formulation of national metrology standards. Our product portfolio includes vibration test fixtures, air-tightness testers, battery internal-resistance testers and integrated safety testers. We have deep expertise in reliability and electrical-safety testing for new-energy-vehicle (NEV) components.

For NEV body and chassis structural parts, vehicle lamps, air-conditioning pipelines, 12 V / 48 V on-board auxiliary batteries, infotainment hosts, central control units and on-board sensors, Hopetech delivers a one-stop test solution covering laboratory reliability validation, mass-production line screening and pre-delivery safety sampling inspection.

✅ Vibration Table Fixture｜Reliability–Test Fixture Manager

Role: Special fixture for vibration and shock testing of body-chassis components, motors, traction batteries and on-board electronic assemblies.

Customer Pain Points Solved: NEVs are subject to continuous vibration during driving, which may lead to loose structures, cracked welding joints and desoldered internal components. The vibration table fixture securely holds test samples and simulates real-vehicle bump and shock conditions in the laboratory. It verifies the structural endurance of components in advance, screens out structurally weak parts and prevents structural failures on finished vehicles.

✅ DT3115B / DT3185B Differential–Pressure Air–Tightness Tester｜Seal–Leakage Investigator

Role: Mass-production leak-inspection specialist for sealed assemblies such as vehicle lamps, air-conditioning pipelines and vehicle-body welding seams.

Customer Pain Points Solved: Water ingress into vehicle lamps, air leakage in air-conditioning pipelines and seepage at body welding seams can directly cause lamp damage, air-conditioning malfunctions and vehicle-body corrosion. The DT3115B / DT3185B series rapidly screens micro-leaks on production lines without damaging test samples. It efficiently rejects poorly-sealed products and guarantees the sealing-protection performance of complete vehicles.

✅ HT3561A Battery Internal–Resistance Tester｜Low–Voltage Battery Health Examiner

Role: Performance-testing specialist for 12 V / 48 V on-board auxiliary batteries and low-voltage energy-storage modules.

Customer Pain Points Solved: Ageing of 12 V / 48 V on-board auxiliary batteries causes rising internal resistance and unstable power supply, resulting in vehicle power-on failures and central-control blackouts. The HT3561A quickly measures internal resistance and open-circuit voltage to identify aged cells and modules at an early stage, ensuring stable operation of the vehicle low-voltage power-supply system.

✅ HT9985A/B Integrated Safety Tester｜On–board–Electronics Safety Guardian Role: Safety-sampling inspector for low-voltage components including infotainment hosts, central-control units and on-board sensors.

Customer Pain Points Solved: Infotainment hosts, central-control units and on-board sensors operate under repeated high-/ low-temperature cycling. Insulation materials may degrade over time and create electric-leakage hazards. The HT9985A/B performs combined hipot and insulation sampling tests to validate the electrical safety of low-voltage on-board electronics, mitigate leakage risks and satisfy automotive-electronic safety specifications.

This complete solution covers the full workflow: laboratory reliability validation, component mass-production testing and finished-product sampling inspection. It helps vehicle OEMs and component suppliers identify hidden risks concerning structure, sealing, batteries and electrical safety. It reduces failure rates of on-board auxiliary systems and supports long-term stable operation of NEV body, chassis and on-board electronic systems.
