Customer specific and standardized vehicle electric centers are electronic units for intelligent control and supervision of the distribution and switching of electrical energy. Vehicle electric centers reduce the cabling effort and allow flexibility in machine variants and accessory options, combined with diagnostic capabilities.
To solve the power management tasks STW offers three approaches:
Intelligent Vehicle Electric Centers
STW offers modular power management systems together with our partner ERNI. Standardized building blocks for switching and distributing electrical energy - the so-called «cubes» - are complemented with intelligent, standardized STW control modules. Here, the automation module is available as an off-the-shelf product.
Modular Power Management
A modular approach adds a degree of freedom for the design. The structural shape of the unit as well as the dimensioning of the circuit components for switching the electrical energy, such as the plug-in relays, can be defined together with the customer. To complete the solution STW offers intelligent modules with a defined performance.
Integrated Power Management
In this open approach STW works closely with the customer to jointly specify and develop the perfect solution. The final product will be a vehicle electric center combined with intelligent modules for control and connectivity within a single unit.
The performance characteristics of the intelligent modules, type, number and characteristics of the inputs and outputs are adapted to the requirements. Even special components such as motor bridges or stepper motor drivers can be implemented.
The structural shape of the unit and the circuitry components for switching relays, such as plug-in relays, are defined according to the desired type, number and required characteristics.
