The battery simulator BNB 8653 has the task of supplying power to the device under test while ensuring a defined source impedance. It has been developed for automotive tests e.g. to fulfill the requirements of the manufacturer standard “MBN 11123”.
The BNB 8653 is constructed symmetrically with two paths, HV+ and HV-, with variable power resistors in each path. A battery can be simulated by various internal resistors. Four possible values are available for Rint: 2 x 100 mΩ, 2 x 50 mΩ, 2 x 25 mΩ and 2 x 10 mΩ (one resistor in each path). The built in components have no specific polarity. Both paths are isolated from ground.
