E/E in the Vehicle Manufacturing of the Future

The automotive industry has realized that software is assuming an increasingly important role in vehicle technology. In the process, the number of lines of code in vehicles has risen many times over. To meet these requirements, the industry is cooperating more and more with technology companies. In this partnership, cloud technologies and mobile platforms are being explored to optimize software processes and digitize vehicle production. In the future, autonomous vehicle systems are conceivable that perform their own tests, updates and coding.

High-Voltage Test Adapters – The Solution for Safe Testing of HV Components

Special test adapters for safe testing of high-voltage components on the HiL tester

If high-voltage components or subsystems of electric and hybrid vehicles are to be tested, HV components must be constructed so that they are safe to touch and all queries to be measured or influenced must be fed to the test system galvanically isolated from the high voltage. Softing realizes special test adapters for HV control units, in other words for Battery Management Controllers (BMC) as well as for Cell Supervision Electronics (CSE).

Passive Cell Simulation for ECU Tests without Real Cells

Passive Cell Simulation by Softing

Passive cell simulations are used to avoid being permanently dependent on real batteries or very complex and expensive active cell simulations during the development of Cell Supervision Electronics (CSE). These simulate the complete cell stack in a balanced state of charge, the individual cell controllers detect suitably charged cells and thus a fully functional battery system.

HV Insulation Fault Simulations for Testing Safety-Relevant Functions

High-Voltage Insulation Fault Simulations

HV insulation fault simulations are used to test and validate safety-relevant system functions, either during the engineering process or also after repairs carried out by after-sales service or the repair shop, or directly on the vehicle.

HV Measuring Adapters and HV Breakout Boxes (BOB) for Safe Working on High-Voltage Systems

High-Voltage Equipment by Softing

Alongside interfaces for tapping individual I/O signals, HV measuring adapters also provide possible access to the HV power supply. In the case of HV breakout boxes, I/O signals and supply lines can be specifically manipulated by using suitable jumpers. Equipped with the original vehicle plug connections, this means that signals at the control unit plug can be measured without any contact or can be specifically influenced by interruption, short-circuit or connection of a bleeder and transfer resistor.
