Your Normal FAQS
Q1: How long is the timeline for developing a HV PDU?
The development timeline depends on the different requirements, project scope, and customer specifications, and we will share with you the first draft PDU 3D drawing within 3-5 days.
Q2: What components are included in the HV PDU?
Power distribution units (PDUs) in vehicle electrical HV systems are typically custom-developed to suit the specific vehicle architecture. As a result, the components vary based on the application and customer requirements. Key components and functions that contribute to efficient power distribution and control include:
Fuses and protective devices
Contactors and connectors
Noise Filters and cooling system
Pre-charging circuits
Current and voltage measurement systems
Insulation monitoring
Integrated control and monitoring units
HVIL (High Voltage Interlock Loop) and shielding
Cables and busbar connections
Except for standard internal components, we also design customized, function-specific modules. Some aspects of BMS can also be integrated into our HV PDU, enhancing system reliability while reducing its overall size.
Q3: Can the components of the HV PDU be specified?
Of Course, Yes! We can communicate with relevant component manufacturers based on your specified brand or model, to production selection and HV PDU design accordingly.
If you don't have specific requirements for the components, we can help you to select suitable and reliable components based on your HV PDU requirements.
Q4: What can you obtain once the final HV PDU proposal is frozen?
We can supply 2D/3D drawing, final BOM list, PDU schematic, and other documents you may need.
Q5: Which applications are HV PDUs suitable?
Any electrical vehicle on land, water, and in the air that needs to distribute high-voltage within the respective HV wiring system. They enable efficient and reliable power distribution in the voltage range from 48 VDC to 1500 VDC and ensure optimum performance and safety in these demanding areas.
