High Voltage Hybrid Battery Chargers

(for professionals only - we cannot sell to individuals)

 

To order, please contact Claude Phipps (crphipps@aol.com). We have now shipped more than 75 units.

Our specialty is custom charger units. 60Hz - 50Hz - 200VAC - you name it! Contact us for details!

 

Our most popular is the QDHC-350A, which has 2A and 6A charge currents, selectable on the front panel.

For reconditioning batteries, you might want the model QDHC-350A combined with the QDD-100 discharger. Another popular charger is the QDPC-160-A, made especially for Japan's 100VAC and 50/60Hz.

We ship internationally, for about $175. Within the U.S., shipping costs are about $100. For most sales, we must insist on PayPal. We cannot sell to private individuals, only professionals.

 

Overview

We designed and developed an outstanding line of industrial quality high voltage hybrid battery chargers and dischargers. These share a unique design without transformers or other heavy, power consuming devices.
Typical weight for standard units is 7 pounds. The control board switches input power directly into your battery and stops the charge at a level which you set. We have an excellent reputation with our customers - and you should have one of our devices for your shop!

Five Levels of Safety in the Design

  • Rectifiers cannot conduct in the reverse direction operated within ratings
  • All components are rated to withstand 2 times their operating voltage
  • Ceramic fuses and a 50A thermal breaker or a solid-state relay in series with battery leads
  • Charge voltage with most units is set with a precise vernier knob on a 10-turn potentiometer
  • All units can operate indefinitely into a short circuit

Comments from Users:

"These are wonderful pieces of machinery. I can tell that you put great care into the design and build of each one! ....It has been working phenomenally. I couldn't have asked for a better charger."
- Max Pfeiffer, University of Washington Hyperloop Project

 

"I don't want to buy something from somewhere else now that I have been spoiled by your charger. I don't see any other chargers for sale that are quality pieces of equipment. I believe in your product."

- Charles Ware, Huntsville Hybrids

 

"Your charger did the trick! I charged the Tesla to 354 volts, the batteries balanced enough at that point that I was able to finish it off with the factory 220 charger and I drove it today for the first time since I bought it 8 months ago!! Thanks so much for all your help!"

- Dennis Horton, North Main Automotive Inc,. Hendersonville, NC

 

"I couldn't make this kind of success story of my business without your products."

- A. J. Kitagawa, Numazu Hybrid Lab, Numazu City, Japan

Note 1:  Price reflects amount of work involved in building the device. For chargers, charge time in table is from dead zero.
Proportionally less for topping up a battery!

Note 2: What you save with a hybrid automobile: 25 kWh from your wallplug costs $2.50. Let's say you drive your
SUV an hour a day. A typical SUV cruising at 60 mph uses 36 hp (25kW) in steady driving. In an hour, that's 25kWh.
Its mileage is 20 mpg. In an hour, it has gone 60 miles, and used 3 gallons of fuel. A gallon costs $2.10, so that hour
cost $6.30 in gas. If it were charging a hybrid instead, at 80% efficiency, you would have saved $3.80/day, $115 a month.
Is that convincing?
