For example, a leading NEV factory used it to test battery packs, identifying ripple-induced BMS errors and optimizing filter designs, reducing power loss risks by 40%. Ngoài ra, it supports FFT frequency domain analysis to locate resonant points that harm battery durability.
OBC & DC-DC Converter Testing: Ensuring Power Conversion Stability
On-board chargers (OBC) and DC-DC converters need ripple immunity testing to maintain conversion efficiency. The High-voltage ripple power supply for new energy vehicle testing delivers up to 1000App ripple current, simulating dynamic load conditions during driving.
Furthermore, it integrates with water cooling system to mimic real operating temperatures (-40℃~85℃) during testing. Besides, it complies with ISO 21498-2 and VW 80300 standards, ensuring test results meet global norms. This solution helped an OEM cut OBC field failure rates by 35% and shorten validation cycles by 30%.
Motor Inverter Testing: Validating Ripple Generation & Immunity
Secondly, motor inverters are both sources and recipients of ripple disturbances. The High-voltage ripple power supply for new energy vehicle testing tests inverter ripple emission and immunity simultaneously, covering 10Hz~200kHz frequency bands.
Ngoài ra, it supports power levels up to 15kW, matching the load demands of NEV inverters. For instance, a OEM used it to optimize inverter switching strategies, reducing ripple-induced current fluctuations from 325App to 80App. Consequently, it enhances motor control precision and extends component service life.
HV Distribution System Testing: Ensuring Circuit Safety
HV distribution systems (PDUs) need to withstand ripple disturbances without insulation breakdown. The High-voltage ripple power supply for new energy vehicle testing applies combined ripple and DC voltages up to 1500VDC, testing PDU stability.
Hơn thế nữa, it features built-in pre-charging and high-voltage discharge systems, preventing sudden voltage spikes. Furthermore, it syncs with oscilloscopes via Ethernet to capture real-time ripple data. A NEV factory used it to validate PDUs, ensuring compliance with LV123 standards and reducing insulation failure risks by 50%.
Integrated Vehicle-Level Testing: Streamlining Mass Production
Cuối cùng, NEV OEMs require efficient, standardized testing for mass production. The High-voltage ripple power supply for new energy vehicle testing integrates with ATECLOUD-like platforms, enabling automated multi-device coordination.
Besides, it stores preset test templates for different models, cutting new employee training time from weeks to days. Ngoài ra, it supports parallel testing of multiple components, boosting daily throughput by 35%. For example, a large NEV factory used it to build a unified test line, reducing per-vehicle testing costs by 28% while ensuring full traceability.
Core Value: Standardized Ripple Testing for NEV Excellence
The High-voltage ripple power supply for new energy vehicle testing combines wide frequency coverage, high power output, and standard compliance. It adapts to battery, OBC, inverter, and PDU testing, aligning with ISO and OEM-specific norms.
Compared to basic ripple generators, it delivers realistic simulation and automated integration. Ultimately, it is not just a test tool but a solution that accelerates NEV production and ensures reliable performance on the road.
