| Schematic Design. The Schematic design phase is the
general mapping of components, the circuits that power them, control
them, and deliver the 'used' power back to the negative terminal of
the battery. In this phase I restrict myself to the general
concepts of the components and how they are fed and controlled.
I do not think about the details of wire gauges, connectors, splicing
methods, etc. I absolutely do not think about where the wires
will be routed or attached. It is important to restrict one's
thinking to the power and control concepts, not the small details.
That comes later.
Here is the first diagram that I
produced during the schematic design of some of the main
components necessary for the operation of the car. These are
items such as the ignition, starter, cooling fans.
On this sheet are the components that I want to map at this time.
The same drawing with the power delivery
layer active. On this drawing, I am figuring out the
organization of the wires delivering power to the components.
The same drawing with the switching circuit
layer active. On this drawing, I am figuring out the
organization of the circuits that activate the relays that control the
components.
The same drawing with both switching and
power delivery active.
After preparing this design, which is not completed, I moved on to
the design development stage of my diagrams.
