How far could a fully charged Hybrid ( say Pyrus ) go when out of fuel?

Question

How far could a fully charged Hybrid ( say Pyrus ) go when out of fuel?

Answer 1

Not all hybrids are able to drive on the electric motor alone.  Most models only use the hybrid system to aid in auto-stop and to act as a turbo.

The next issue is how did you get a fully charged battery in your hybrid?  The hybrids have advanced computer controls that do not fully charge or discharge the battery, to prolong its life.  Also, there are no commercially-available plug-in hybrids, so there is no charging off the mains to bring the hybrid battery charge up.

There is not a lot of capacity in the hybrid battery on a Toyota Prius for much electric-only propulsion.  The longest distance I've heard of for a Prius coasting after the out of gasoline warning lights, was on a UK Prius, that went about 7 miles after running out of gas while doing high speeds going downhill...  Typically you could expect less than 2 miles, depending on terrain and state of charge when you ran out of gasoline.  But the Prius is not an electric vehicle - it is intended to be driven with gasoline, and one should not run out of gasoline (both for the safety/lifespan of the engine and the hybrid battery, and for that of the occupants that may be stranded somewhere unpleasant...)

(To note, there is no "Pryus" - perhaps you are mispronouncing the Toyota Prius (pronounced PREE-us or PREE-oos).)

Answer 2

The one EV car I currently have (have 2 vehicles that run on hydrogen also) I converted from a vw bug and is free to charge. As I live completely off the grid all my electricity comes from solar panels and 2 wind generators, which I also built.

However I did charge up at Costco in Carlsbad California (I actually only drove up there to fill up) if I remember right it was around $2.00

Not sure if you’re interesting in doing it yourself, but I’d be willing to walk you step by step threw the conversion. I've converted 3 of my own cars (a datsun truck, ford ban, and a vw bug) and a few for neighbors. I've also converted cars to run on hydrogen, ethanol and biodiesel, by far EV is the easiest.

If you’re interested here’s what it would entitle…

- The engine compartment is first cleaned out of any gasoline components.

- Electric components are then installed in exchange.

- A battery bank is built and incorporated.

- Existing starter and driving systems are connected.

- Turn the key, step on the gas pedal sending more energy to the electric motor, & thus more power to the drive system, which in return creates more speed, more acceleration.

- The system has normal automotive top speeds and acceleration, typical to the vehicle your modifying. If your top speed was 85 mph and your acceleration was 1 mile per min, then this will be what your left with after the conversion.

The methods are extremely simple, making the process possible for anyone, everyone, ANYWHERE.

Typical tools, hardware & supplies are used, making access to parts available for all.

Electric Conversions can be easily accomplished in ANY model vehicle, even tractors, Generators, types of machinery, etc.

Project lengths range from 1 day to 1 month.

If you’re interested I wrote a guide on it which is available at www agua-luna com

My last EV conversion ran me about $1400. Everything is available online. I have a how to do it yourself guide available at www agua-luna com that will walk you step by step through the process. If you have ANY questions feel free to contact me through the site. Here’s a list of what you'd need...

Advanced DC Motor

The motor is an 8" Advanced DC series-wound motor. It weighs 107 pounds and is rated at 68 peak horsepower. These motors are available in several sizes.



Adaptor plate

The adaptor plate mates the motor to the transmission. It is constructed of 1/2 inch aluminum and is pre-drilled with bolt hole patterns for both the motor and transmission. An aluminum spacer is also used for proper spacing between the shafts of the transmission and motor. Adaptor plates are available for many cars.

DC Motor Controller

The controller regulates current going to the motor. It is a solid-state device that uses a pulse width modulator (PWM) that sends short bursts of current to the motor at a rate of 15 kHz. Controllers are available from both Curtis and DCP.

Potbox (Potentiometer)

The potbox is a 5K ohm throttle between the controller and the accelerator, similar to the way a sewing machine pedal works. The potbox's lever arm is attached to the existing accelerator cable.

Main Contactor

An electric relay that serves the same purpose as the ignition switch in a gas car. When the key is turned to the start position, the contactor closes the circuit to allow current to flow to the controller.

Circuit Breaker

A safety device that shuts down power for servicing or during an emergency. The circuit breaker is installed under the hood and can be switched both off and on from the drivers seat with an extension or cable.



Main Fuse

The main fuse protect the system from high voltage spikes. A fuse should be installed at each battery box or group of batteries.



Shunt

A shunt is placed in series within the wiring as a means to connect meters. Shunts are available in different sizes for both high and low power configurations.

  

Charger interlock

A relay that keeps the circuit open so nobody will inadvertantly drive off with the charge cord plugged into the car.



DC/DC Converter

The DC/DC converter is similar in function to a gas car's alternator. It charges the 12 volt accessory battery by chopping voltage from the main battery pack down to 13.5 volts.

If you interested I offer several DIY alternative guides to walk you step by step threw EV conversion process at agua-luna com or

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at  www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Answer 3

Prius is the exception. They can travel over 20 km.

My friend says that in city driving his batteries are rarely fully charged. They would not be providing much benefit if they were fully charged, because they need to have a place for stopping energy to go.

Most other hybrids will not do much driving on battery alone.
