HV Components
Complementing its standard connector portfolio, Rosenberger develops and manufactures customer-specific high-voltage components for electric and hybrid vehicles. These enable the lowest possible transition resistances, ensuring long-term low-loss performance and reliability in critical electrical systems such as battery charging, cell management, heating, and air conditioning.
From concept to final delivery, Rosenberger high-voltage custom components are the perfect fit every time. Using its component toolkit, including PDUs, Y-splitters, busbars and cell module connectors, Rosenberger can develop and manufacture a wide array of tailor-made solutions. These are designed and configured precisely to the relevant vehicle architecture, allowing ideal combinations of various fuses, relays and other passive and active components required.
Product Portfolio
- Cell module connectors and busbars
- Power distribution units
- Y-splitters (aluminum housing)
- Contact systems
- Insulation material
The Rosenberger HV portfolio also includes busbars or cell module connectors according to customer-specific requirements. These connectors are required to link battery modules within a battery pack. For typical battery applications, multiple custom-designed battery connection points are required.
Based on the robust butted contact system, Rosenberger offers cell module connectors with integrated flexible tolerance compensation. Systems from 100 to 350 A are available.
Different assembly directions, coding variants as well as cross sections can be implemented according to customer-specific requirements.
Features
- Current capacity (95 mm²) 270 A at 85 °C
- Working voltage 1000 V DC
- Cross sections 70 mm² to 95 mm²
- Engine vibration 2 according to LV 215 (GS95031), M-04 profile D according to LV124 (GS95024)
- IPXXB protected center screw
- For unshielded copper cables (round, flat)
Y-splitters are used to distribute the power from one cable harness to two or more units, e.g. between a DC/DC converter and an electric air-conditioning unit.
Rosenberger can design Y-splitters for applications with or without shielding for cable cross sections from 4 mm² to 95 mm² in collaboration with the customer.
Benefits
- High-flex cables (round)
- Robust pressure contact system
- Ensures proper electrical connectivity
- Lower size and weight
- Rigid or flexible variants
- Safe and quick replacement
- Reduces electrical loss at connection points
- Different assembly directions, coding variants as well as cross sections
- Customized designs
Power distribution units (PDU) for vehicles have multiple power input and outputs and use all kinds of connectors, fuses, and relays. In these cases, the PDU generally forms the central link between the vehicle power electronics and batteries, electric motors, and other ancillary units.
Applications
- E-mobility
- Charging
- Electrical heater
- Electrical air condition
- Battery charger
- DC/DC converters
