Y love affair with electric vehicles began when my dad let me steer a golf cart. I was six. I was fascinated with the hums, whines, and squeaks that came from a vehicle powered by black boxes.Something magical happened inside the golf cart's batteries, but I soon lost that early curiosity. Years later, I rode in the CommutaCar in Sebring, in dozens of near-production models at EVS-12, and at numerous car rallies. Still, I never gave the batteries much thought until I began compiling the first...

Automagic Battery Watering

WE MAKE WATER FROM YOUR GAS Hydrogen and oxygen battery gas catalytically recombined into pure water and returned to each battery cell. Keeps battery topped off for extended periods of time and reduces maintenance costs. Explosive hydrogen gas is virtually eliminated from the battery area. Corrosive spray and fumes are contained and washed back into each battery cell. Electrolyte kept strong longer, extending the useful power and life of the battery. HYDROCAP Vents simply replace the battery's...

Read Your Mailing Label

We don't send out renewal notices for your Home Power Sub. The last issue of your Home Power Sub is printed on your mailing label. Check it out and don't miss an issue Dear HP Crew, an excellent publication. Much attention is paid to the electrical aspects of solar electric panels. I wonder if you could Ask NREL to elaborate on the physical and structural aspects of solar electric panels i.e. Please describe the hail impact test and wind loading test. Obviously solar panels are designed to be...

Steering Wheel

Note A vehicle that switches this much battery power mechanically must have a power cut-off and fuse. A simple, hefty knife-switch does just fine. Be sure the base is a non-conductive bakelite or phenolic plastic. You can mount the 500-amp fuse separately or combine it with the knife-switch as done here. If you use the fuse as the knife-switch lever, put a reinforcing bracket on it so that it doesn't break. Fuses aren't designed to take this type of mechanical stress. I've wrapped a large cable...

Pwm Charge Controllers Are Becoming More Popular

Twelve years ago Heliotrope General pioneered this concept with the introduction of the CC-10 PV charge regulator. Prior to this time all PV chargers were simple on off regulators. The problem with an on off regulator is when the desired regulated voltage is approached. At this point charging is turned off and thereafter you get a lower battery voltage reading. PWM (Pulse Width Modulation) strategy takes over when the battery has reached the point of voltage where other chargers turn off. PWM...

Above The Solar Energy International class and Jane Sharp in front of Jane's new photovoltaic array. On the day before Earth Day '95, thirty students arrived at the home of Jane Sharp in a residential area of downtown Chapel Hill, North Carolina. By afternoon of the next day, with the help of savvy friends and technicians, she was plugged into the sun. A solar-powered system had been installed that would run her lights, a ceiling fan, a television and radio, an answering machine, and her...
