Electrical
Development
Are you developing an electric machine and need to integrate high- and low-voltage systems safely and reliably? We support you in the design and implementation of the electrical architecture.

Electrifying a vehicle or machine requires a complete redesign of the low-voltage supply and the setup of a high-voltage onboard electrical system.
Future-ready machines consist of a wide range of components and sensors that must be interconnected and controlled. While the low-voltage supply ensures basic functions, the high-voltage system powers high-demand components such as the motor, inverter, chargers, and battery.
A clean electrical design is crucial for the performance, safety, and reliability of your machine.
What we do
Electrical development of vehicles or machines
For innovative electric drive systems
Electrical system architecture (HV/LV)
We develop high- and low-voltage onboard electrical systems and define the electrical architecture of the entire machine.
Wiring harness design
We create electrical schematics with EPLAN P8 and model wiring harnesses in 3D to enable full integration into the overall model.
Component sizing
We size components, cable cross-sections, and fuses for high-voltage systems and ensure performance capability.
Electrical integration of drive, battery, and chargers
We connect motor, inverter, chargers, and traction batteries into a coordinated system using our configurable products.
Software integration and connectivity
We integrate control units and displays and enable machine connectivity for later service and remote maintenance, as well as over-the-air updates (OTA) for control units (VCU), to enable remote software updates and reduce the need for manual on-site interventions.
The result
Your benefits
You receive a holistically designed electrical system architecture including all relevant components, interfaces, and supply structures.
The systems are designed to operate safely, powerfully, and reliably in real-world use.
