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

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.
