[0002] With the popularization of new energy vehicles, the platformization of electric drive systems has become a future trend. The diversity of vehicle layout and performance requirements also brings corresponding difficulties to the reliability of vehicle interfaces.

[0003] To achieve platform-based electric drive systems and accommodate diverse vehicle layouts, existing high-voltage busbar connectors are mostly 0-degree or 90-degree adapters. This wiring method conveniently accommodates the location of the battery interface and the electric drive system interface. To achieve platform-based electric drive systems and adapt to different vehicle models, the location of the high-voltage busbar outlet is crucial. Sometimes, due to limited space, if 0-degree or 90-degree outlets are not sufficient, the powertrain outlets may interfere with other components, hindering the proper platformization of the powertrain. In this case, the controller busbar outlet becomes a bottleneck, and the cost of developing a new electric drive assembly is high. Utility Model Content
