I am a seagull,,,
My name is JonaSun,,,

I will introduce how to runs this time.

It is a method to call energy management to say commonly.

We fill up gasoline before a tank empties while taking a meter of gasoline be a general car.

However, We have to always control a residual quantity of battery because Solar-car generates electricity while running.

Control of this residual quantity is the most interesting part of Solar-car race.

So that a quantity of generation changes by a change of mule weather why.

The left photograph is basics data of generation multiplication that I used with WSC of 1999.

A lot of universities and high rank teams are using a computer for the energy management.

This graph paper and an electronic calculator and a pencil are main tools of our team.

At first I explain a viewpoint of a graph.

Side course is progress time.
I enter in from 8:00 a.m. to 17:00.

A vertical course is multiplication value of quantity of generation.
If weather is good, a graph will spread aloft.

The generation situation of past test is filled in this graph paper with.
I will write in data of the day on this graph on the race day.
Expectation of generation value of the evening is made at around the daytime.

A lot of data are necessary for this method.
A lot of I whom I test have a lot of data than anyone in the world.

I decide quantity of next usable energy.

What we must pay attention to here.

How many energy left only with which in battery in anticipation?

And we must grasp whether we leave energy in it.

I understand it if I take specifications of battery be a race only a day.

It is a multiplication meter of Namikoshi that is beneficial at this time.

We decide a quantity of energy that we can to eat by a motor on the basis of numerical value of a meter.

The team that making a traveling plan with a computer do not need this graph.

A graph of JonaSun type is a method of recommendation to people of a team enjoying a race by a hand calculation.

The reason is because it can collect only data of generation in a corner of school grounds.

Without test running.

It was demonstrated that we cannot ignore a hand measurement by an American presidential election.
