QMA

Complementing its standard HV 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 those for 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 Modules, 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 the various fuses, relays and other passive and active components required. Power Distribution Units (PDU) 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. Y-Splitters 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 and without shielding for cable cross sections from 4 mm² to 95 mm² in collaboration with the customer. Cell Module Connectors The Rosenberger HV portfolio also includes cell module connectors. 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 pressure contact system, Rosenberger offers cell module connectors without flexing parts in the contact area. 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.

The Rosenberger HPK system can achieve 275 A at 85 °C up to 1000 V. With their excellent vibration and current capacity performance the HPK connectors are well-suited to typical high-voltage electric vehicle applications such as the connection between battery, inverter and PDU. The range includes 1-, 2-, or 3-pole connectors which for maximum flexibility can be used with copper or aluminum cables in four different cable cross sections. Straight and angled cable couplers as well as corresponding headers are available, either with or without HVIL (high-voltage interlock).
