AutoTech Video: A Week In A Toyota Prius Plug-in

The Chevy Volt and the Nissan are enjoying lots of free right now. Each of unique approaches to cleaner has drawn a lot of hype. What the car that started it all? the next step for the Toyota

Though battery technology not yet rival the energy density of that hasn’t stopped the Volt and Nissan Leaf trying. Toyota, with more than 14 years of experience, must have a solution, right?

Toyota has investing significantly in their “plug-in hybrid” Prototypes: offering a combination of an internal engine and a battery electric Has their worked paid We got one week with the Prius to find out if it’s energy meets our needs.

The car appears to be a Prius. Aside from lower body graphics and a out for the plug near the driver-side most of the changes involve the powertrain. The older Prius’ hydride battery gets with a bigger, more lithium-ion pack. Ancillary such as high-voltage lines, charger and thermal management also added, but aren’t visible.

The new battery can achieve a full in about three hours a 110-volt outlet or in about an and a half with a 220-volt. I a 220-volt outlet in my garage, so was never an issue. 220-volt aren’t uncommon in US homes — for most dryers and electric have them, though may not be easily accessible for vehicle

Because the Prius PHEV is in the stage, Toyota will be the data from the fleet of 150 to determine if the battery size is for most daily commutes. I wanted to do my own experiment to see whether or not the PHEV would fit my (mostly driving habits. For this I kept a driving journal miles driven, charge and fuel economy in both and hybrid-electric modes.

Driver’s Log

I many entries the week I with the Prius, but for the sake of I’m listing the three most scenarios.

Trip 1

My first commute driving to two stores on different of town for general errands. The leg to get a new lens for my camera was only 3.7 — this, of course, was done on all From a full charge the meter showed 13.6 of range, at the destination it showed 9.6 left. Not bad.

Afterwards, it was on to Joe’s for some groceries, 5.2 miles away. For this leg the meter underestimated range by 1.4 Still, not bad. 3 miles of range were left it was time to go back home. I less than 3 miles the Trader Joe’s, so I decided to the car a bit harder on the way back. Once the trip the engine briefly on to assist an apparent hard I made the 1.3-mile trip with 0.9 miles of battery 10.2 miles traveled 0.9 left means the full would last 11.1 under these particular conditions. I was impressed because it was 22 F that day and electric cars lower range in the cold. was all the driving I had for the day, but if I needed to go else it would only be a wait until the battery be fully charged.

Trip 2

This next involved about 100 miles of driving at 70 mph. The fully battery estimate was 11.8 This estimate always depending on many variables, but I it was less when cold The 11.8-mile estimate ended up 15.3 miles before the hybrid mode the Prius is for kicked in. I ended up getting miles in EV mode because two of those miles were in the the rest were on the expressway 70 mph.

Interestingly enough, the battery doesn’t have current to maintain speeds 65 mph without assistance from the Much of those expressway were assisted by the engine, the increased battery life of miles. After the hybrid took over the energy shifted from either the or battery, or a combination of both. all depended on a variety of constraints battery state and road

Nonetheless, the Prius PHEV was to get me to my destination and back (100 with a fully charged and less than 2 gallons of If I were in a Nissan Leaf the wouldn’t have been though, to be fair, the Leaf officially rated for a trip long, except in marketing

Trip 3

Trip 3 wasn’t different from Trip 2, that the route had many signs along a 2-lane This 28.7-mile trip to get raw from the local dairy started with 14.3 worth of gasoline-free driving. Eco which keeps pedal minimized during acceleration, is responsible for the better range. it activated the car was less motivated to saving the battery from my foot.

After the charge ran out the resorted back, once to the familiar hybrid mode. because the Prius PHEV’s system runs at a higher the average fuel economy was 62 mpg — better than the normal Drive routes with stops actually decrease consumption; the car has a chance to capture energy from regenerative A time out for the engine, if you will.

Is the Prius PHEV the next

From my experience behind the of the Prius PHEV, I’d say that the offered make it a very alternative to battery-only electrics. though two of the three trips driving further than 12 keep in mind I spent a lot of driving the car that week for review. If it were a normal my daily mileage would been less than 20

Not only are plug-in hybrids the step because of their but the more robust lithium-ion vastly improves fuel over the regular Prius operating in the hybrid-only mode.

the estimated price is $27,000, but not an accurate number for a number of The first few vehicles are prototypes; the size hasn’t been Toyota engineers are collecting from all the prototypes running the world in an attempt determine range would be appropriate for drivers. It’s not 12 miles, but not far off either. If the production Prius could hit 20-30 miles, Chevy and Nissan will have to worry about the
