BNB 8651-40 – Battery Simulator
The purpose of this battery impedance network (BNB) is to provide electric power to the device under test, providing a standard impedance. It has been developed for automotive tests. A resistor that emulates the internal battery resistance is implemented in the BNB.
A battery could be simulated by different internal resistors. There are four possible values implemented: 2 x 100 mΩ, 2 x 50 mΩ, 2 x 25 mΩ and 2 x 10 mΩ (with one resistance per path).
