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.

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.

Caution: High Voltage!

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.
