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 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.

During the development of electric and hybrid vehicles, high-voltage capacity decades (HV-C decades) are used to replace the DC link capacity in the vehicle. Thus, they simulate one of the most important energy storage devices of the power electronic vehicle system.

How Customers Benefit from International Standards – The use of standards in the Automotive sector generates significant efficiency gains. Tests can start earlier due to the unambiguousness of data descriptions, ECUs become less expensive due to standardized buses and protocols and the use of uniform runtime environments saves rework and maintenance costs.

We are pleased to invite you to the next virtual "Softing Automotive Convention" on October 20 and 21, 2021. In our virtual showroom, you will have the opportunity to experience our software solutions and exhibits easily in your office or from home. In addition you can expect various live demos and presentations.

Nowadays, the development of vehicle components and their integration into the vehicle are hardly conceivable without high-voltage technology. The demands made on the electronic testing and verification systems used for this purpose are extremely high and diverse – particularly in the case of electric and hybrid vehicles. Here, safe measurement, testing, verification and application in the high-voltage range are just as important as knowing how to handle complex ECUs or use transparent and reproducible test procedures. Ideally, the tests and checks run automatically with processes and test results recorded accordingly for the necessary proof and certification. This also requires suitable simulations and HV-compatible accessories.

In daily operation, ECUs in the vehicle are exposed to a wide range of environmental influences, such as vibrations, strongly fluctuating ambient temperatures and high humidity. The components must therefore be able to handle all conceivable faults. For the test, these faults are simulated on the ECU pin and the respective behavior and diagnostic entry documented. Typically, such fault simulations are used for function tests during development, for testing, release and validation of ECUs and components, as well as for integration validation during HiL testing or at the Functional Mock-Up (FMU).

It is a long journey from the start of engineering to the installation of all vehicle components and ECUs in the production vehicle. Comprehensive testing of the electronic components during the entire engineering process is essential. This is the only way to thoroughly safeguard and optimize hardware and software functions. Errors can be detected and remedied quickly – the earlier the better.

Invitation to the Virtual Softing Automotive Convention on May 5-6, 2021 | Due to the severe restriction of personal contact options since last year, we had to completely rethink events and customer appointments. With a creative digitalization concept based on current technology, we have created a virtual space that offers us the ideal event location. It allows our customers and partners to experience software solutions and exhibits in the office or at home.

A large number of different cables, adapters and peripheral simulations are used in the engineering of vehicle electronics, the testing of electronic and electrical components and in component integration into the complete vehicle. The use of standard products is rarely possible here. Test equipment specially adapted to the control unit, vehicle series or test environment is nearly always required.
