Evmixer Help

The application allows  to set or modify some statistical properties, in a fleet of electric vehicles, and to simulate its behaviour regarding the total load power profile.

Interface layout

The application interface presents a left hand side control area  and a right hand side resulting graphs area.

Control area

Control   is organized as a column of subwindows. Each sub-window  is devoted to a  particular attribute or property of the vehicles, such as type, allowed load current, ...

A sub-window has  a label, a group of sliders, and a half-pie.
The label is the name of the particular property. It has a question mark button which gives a short information.

The property may have two or three values. The  relative statistical percentages of these values in the population are controlled by a group of two or three sliders and displayed in a half-pie.

Each slider in a group allows to increase or lower its associated value, but as a side effect, it modifies also the other values in such a way that the sum remains  always 100%.
So, when you drag a slider all the percentages are modified, and many sliders positions  lead to the same pie repartion, as in the two following figures.

Resulting graphs

The top graph represents a one day reloading power profile for a virtual  mean vehicle.

The bottom graph represents the impact of the reload on the load curve of Ile de France. This impact is obtained  for a particular total number of vehicles. This number of vehicles is  controlled by a slider on top of the graph.
