Toyota Prius Plug-in — First Drive



Toyota Plug-in Hybrid — Drive

I’ve just an unusual week with a Prius PHV (Plug-in Hybrid It may be the future of the Prius, but you can’t go out and buy Yet It’s one of 160 factory plug-in that have been in use by government agencies, car-sharing and corporate fleets for the past as a beta-test program for Prius

Inputs from driver will be used in design and of future Toyota hybrids. there have been plug-in Prius conversions, is the official factory PHV program. tell of my experience in a moment, but some background.

If you’re not with the term plug-in it means an internal combustion-electric that can be also recharged by to the power grid, so it can operate as an vehicle (EV) to a greater This may require an extra pack dedicated to electric If that sounds more a little counterintuitive since the for a hybrid its independence from an electrical supply, a plug-in has one major advantage over a electric vehicle — the electric-power battery runs the plug-in still runs as a hybrid.

As long as there’s fuel in the no problem. No fuel? Call a tow like anyone else in situation.

Compared to a regular the PHV can operate under electric for a greater range or at higher

The Prius’s nickel existing battery pack was not designed to be by a connection to the power grid. recharged by the traction motor-generator operation of the car. So a plug-in needs extra battery for plug-in electric-mode power, and of the car’s electronics to allow use of power. In this case, additional lithium-ion (Li-ion) packs are added, one primary and two with the primary and one of the secondaries power for EV mode.

When the secondary discharges, the second is online. When it and the primary it’s back to regular mode until recharging.

are advantages and disadvantages to the plug-in On the plus side, an EV or plug-in can be charged from the power Its charging circuitry can be designed and to allow charging from 110 or 220VAC house power, need for an expensive special station.

Electricity is less per mile traveled than fuel.

Negatives? The additional battery and circuitry, plus physical and system modifications add weight and Weight is the enemy of efficiency, so too extra weight and more will be needed, which require more power (battery) which will more weight and the greater the capacity, the longer the charging for any given voltage.

Meaning there will be a practical limit on battery size, and range. Note that the constraints also apply to fuel tanks.

The necessary are not fatal to the plug-in concept. For people, most driving is short trips. The worst you can do to an internal combustion engine is so short a distance that it reached optimum operating If you make a lot of short trips, an EV is a choice of vehicle — but range can vary wildly driving style, terrain, and

There is currently little infrastructure, and current batteries time to charge, even for distances. So if you miscalculate the range of EV, it’s tow truck time.

The obviates that, as long as also fuel in the tank. And it can as well as any regular internal-combustion car for transportation, as it reverts to regular mode when the EV battery is So think of it as two cars in one — an EV for around-town driving, and a standard for that and longer distances.

That takes up less in your garage, and takes from your budget.

How it work and how well does it

Fine and just like any Prius, if you want the short While it’s possible to charge the Li-ion batteries and use it as any other Prius, that be missing the point. The only way to Toyota’s plug-in from a Prius is an extra fuel flap on the left front (The regular fuel is on the left rear.) That’s the port.

The charging process is — plug the included and cable into a grounded socket, 110VAC for a three-hour time or 220 for 1.5 hours. I unplugged my ran the cable out the window into the connected it to the car, and in the advertised hours the charge light on the went out, indicating a charge.

Toyota says the EV-mode range is 13 miles. this doesn’t sound much, it’s enough for daily tasks, or even a commute — especially if the car can be during work. And in reality, EV range can be considerably longer 13 miles. This is because the may come on during EV mode, and some motive power. more than three-quarters acceleration, when climbing a hill, over 60 to 70 mph, the air is unusually hot or below freezing, or the air conditioner is in use on a hot day, expect the to come on at least occasionally.

As with a regular Prius, usually so subtle that have to look at the power to tell.

EV purists may complain, but also means the EV range can be than 13 miles. I found it to be to 25, on trips that included city and 70mph highway Yes, the engine came on at

But a look at the bar-graph fuel display, divided into intervals, showed plenty of 100 mpg the maximum displayed and meaning no gasoline consumption — the balance ranging from 75 mpg to a low of 25 full-throttle acceleration up a steep EV mode regularly returned 75mpg average, a good above the standard 50. Think of it as an electric vehicle than as a that operates electrically than, and at higher speeds previous hybrids.

On the road, the PHV and works like any other The suspension is soft, but well-damped, doesn’t have much feel but works well, and the is quiet. There are some sounds related to system but this is an experimental test — which from means that’s its made as as any standard production vehicle. The PHV feel heavy, but only it is. Official weight has not been but the Li-ion batteries add 330 pounds, and cooling system adds more.

It’s noticeable when but the suspension seems to have modified to deal with it There is no negative impact on economy. No negative at all, except that you can’t buy


You’ll have to until early 2012 for an Prius PHV, which be introduced first in the parts of the where the Prius has proven to be popular — California and the As availability increases, it will across the country.

Will the version be like the experimental I drove? I expect it to be similar in but somewhat different in detail. is not known for resting on its laurels. The implementation runs in EV mode as as the Li-ion battery is charged.

Perhaps it could be user-programmable to off on that — no point in up the battery on the highway when destination is city traffic, EV mode would be more

Also note that of the space needed for the Li-ion pack my test car was missing a chunk of luggage space and any of spare tire. The tires not run-flats; the tire repair kit was a PR person’s cell phone Gotta love experimental  You know the production will have those ironed out.

Is a plug-in for everyone? No. And if you don’t have access to power where you there is little point. But the PHV is one step in fuel efficiency.
