Its needs to the system could be provided with a hunk of wire untill time came where protection was needed. Then the control unit could suffer.
The point to remember is that the device plays no part in decisions. It only powers up the system. Think of it as a UPS for the cars computers. As far as running the PC a wall outlet would be just as good, but we use UPSs to protect the thing from lightning/etc. Our software is totally not concerned with whether the power came from the wall socket or the UPS. Same holds for the OVP.
