High Voltage Hybrid Battery Chargers

                           (for professionals only - we cannot sell to individuals)


**Please Note: 

We are again producing chargers and accepting orders! Please contact Claude Phipps at crphipps@aol.com
indicating which unit you would like to buy. Our most exciting new unit is the model 330, which will charge
all batteries faster at a more constant rate. Check it out!



We designed and developed an outstanding line of industrial quality high voltage hybrid battery chargers. 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 to use in your shop!

Five Levels of Safety in the Design

We build when you order. For the model 450, you attach your own power cables to terminals at rear of unit.

Two model 450's mounted in one rack will charge a 405V 85kWh battery in 2.5 hours. Total cost with rack about 22k$.

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?
