Hello All,
I posted a little note a while back about our use of the HB on the two
bikes that our local high school is using in solar bike races in Topeka and
Akita, Japan. Well the races are over and I thought that some of you may
be interested in the results.
The bikes are stock bike frames with motor power, a minimum of 1.2 sq.
meters of solar panels and batteries. The electrical system is
supplemental to the rider supplied power. The races are 100 km. The idea
is to make the best use of what power you have to help the rider. The HBs
were used to monitor battery voltage and current, bike speed, and control
settings. The HBs were also able to directly control the solid state motor
speed controllers. The displays gave the riders information like battery
voltage, current, accumulated amp-hours, speed, and control settings. All
in all it worked great.
So for the results;
In the SunRaye in Topeka ;

Our Boys team took a second place in the “A” category under 18 group.
The girls team took a first place in the “A” category under 18 group.
In the World Solar Bike Race in Akita ;
http://www.ogata.or.jp/english/wsr/98wsbr/98wsbr.htm
The boys team took first place in the “A” category overall (that included
the under 18 and mens groups).
The girls team took a second place in the “A” category under 18 group.
Both teams took first place in the spring portion of the race. That’s
where they sprint a short track before the race for starting position.
The link to the Akita race has a few pics of the bikes and riders. Its a
little hard to see but the HBs are hanging from a set of Aero Bars located
on the front of the handlebars.
A few months ago when I first posted a message about this I got a few
requests about the details. That is coming (I hope). I’m trying to get
the kids to do that. We are starting up a web page with pics and details
of the bike. BUT.... These a re HS kids and it is summer and... and...
and..
Anyway I thought I would pass this info along since we did use the HB on
the bikes with what I consider great success. Being able to know exactly
how much power is being used from the batteries and having the ability to
accurately control the power consumption is a valuable tool. (Plus I’ve
got more bragging rights than most on this project since my son was one of
the boy’s team riders)
Special thanks to Fred for the design and the advice he was able to give us
when we had some charging problems in Japan. (If your taking one of these
thing to Japan don’t forget to factor in the 100V AC they have)
