Power Supply Function
This test simulates the slow decrease of the vehicle system
voltage to the energy storage protection voltage followed by
shutdown to 0V and the sudden reconnect the system volt-
age by a charged or new energy storage battery.

E-08 Reset behavior
The reset behavior of a component in its environment is si-
mulated and tested. Test boundary conditions (e.g., assem-
bly, terminal, system) must be described in detail. During
operation, an arbitrary sequence of repeated switching-on/
off procedures occurs; this must not lead to an undefined be-
havior of the component. The reset behavior is represented
by a voltage variance and a time variance. Two different test
sequences are required to simulate different switch-off
times. A component must always undergo both sequences.
E-10 Start impulses
During a cold start (motor start), the energy storage battery
voltage decreases for a short, then increases again. The
warm start is not considered, because the operating range is
maintained.
Normal Standard experimental pulse
Severe Enhanced experimental pulse
E-15 Operation in the range without function restriction
The operating behavior at the range limits is checked.
E-16 Operation in the upper range with function limitation
The operating behavior with change and at the range limits
is checked.
E-18 Overvoltage range
The test is to show the load cut-off during storage charging
and check the changes of the operating behavior into the
overvoltage range.
