| This
has been another exciting weekend. We had an incredible successful
test day and through the weekend managed to put over 110 track miles
on the car. The different challenges of a new track continue to uncover
new places for improvement. |
| Mechanically,
a water leak and a poor battery support design cost us a qualifying
session and a race. |
| Electronically,
our attempts to keep the Max. Regen Voltage as high as possible seems
to be shutting down at least one motor. This cost us two laps in qualifying
and a lap in the Sunday race. |
| We
also need to improve the reliability of our DAQ equipment. |
| On
the plus side, in addition to a fourth place finish, we are taking
home a great deal of information about racing an electric car. |
| |
| |
| We
have learned: |
| ...
that we can draw 90% of the pack's rated capacity while racing the
car at 400 amps. |
| ...
that Regenerative braking is ineffective the first 6 racing miles.
|
| ...
how the inverters affect the car so it drives differently at the end
of the race than it did at the beginning of the race. |
|
... what a racing full discharge looks like and how the power fades
at the end. |
