As electrification accelerates, the demands on vehicle power electronics continue to grow. ZF’s co:SELECT converter platform is designed to meet these evolving requirements with a highly integrated, scalable architecture that supports both vehicle efficiency and broader energy grid interaction.
Managing power distribution in battery electric vehicles (BEVs) requires high voltage components well beyond the traction inverter. The co:SELECT platform consolidates key functionalities such as:

✅ Bi-directional charging
✅ High voltage auxiliary power supply
✅ Supplying low voltage on board power systems (HV to 12 or 48 Volt)

Engineers will appreciate the platform’s modular approach spanning all major voltage classes, enabling OEMs to configure functionality according to vehicle segment and performance targets. Its 98% efficient bi-directional charging supports both V2L (vehicle to load while charging) and V2G (vehicle to grid), enabling a BEV to supply external loads and feed energy back into the grid.

🔋 A key differentiator is the high level of functional integration within a single housing, combining galvanic isolation, power conversion, and multi voltage power supply. This reduces component count, wiring complexity, and packaging challenges - critical factors for improving system robustness and cost efficiency.

⚡ ZF is already moving toward a full X in 1 integration roadmap to further condense multiple power electronics functions into an even smaller footprint, supporting highest power density and simplified vehicle architectures.

🔧 For engineers shaping the future of e mobility, co:SELECT represents a forward looking solution for efficient energy management, scalable design, and grid interactive capabilities.
