The power of battery cells is not disengageable and therefore requires reliable safety elements. In order to ensure reliable operation, component related as well as system related load tests are required. This way the components reaction to a short circuit or over load can be assessed. A specially designed test bed allows tests with continuous load of up to 12 kA at 1 kV (12MW), while performing synchronous measuring of all desired voltage and current values at 1 MHz. In addition, the temperature of system components can be monitored. In order to fit the trajectory of the current to real testing conditions, it can be pre-defined. The configurable test bed allows scalable load conditions and automated analyses of the reaction of the safety components. Despite the anaylses of whole battery systems, the analyses of components only, such as, cell stacks, cable, BJB, fuses, relays, pyrofuses or others can be performed.
