Prius Plug-in Versus Volt: Which Costs Less to Drive?

http://priuschat.com/forums/toyota-...92-2012-prius-plug-in-product-info-pdf-8.html

It's true that 27 kW is at the high end of city driving which spends most the time closer to 5-15 kW. On the other hand, discharge power near 27 kW is common at slow highway speeds such as PiP drivers attempting to stay under 62 to avoid engine startup. Constant slow highway driving may take less than 15 kW but urban commuting at highway speeds commonly involves accelerations near or above 27 kW.

 

As was said, in those senarios of accelerations the engine will kick-in.
You are guessing, and your 6C may well turn to be only 3C, and, as you put it, there are batteries designed more toward energy density and orthers toward power density.

Sorry for the double post. Don't know how to cancel one.

 

However, those batteries are run within a very narrow SoC range compared to what the PiP will need to support.

Just to add another detail to the mix, I just read a Toyota SAE paper published in 2010 which said the prototype PiP battery could output up to around 40 kW. Of course, they shrank the pack size 15% for the production car, the cells could be different, and they could be limiting output for battery life reasons after gathering prototype field data.

 

Even lithium batteries are happiest operating in a similar narrow range of charge for maximum cycle life.

The paper I mentioned earlier is Development of Exhaust and Evaporative Emissions Systems for Toyota THS II Plug-in Hybrid Electric Vehicle.

 

Is this specific to the PiP or true to all 1.8 l Hybrids?
If its an improvment made to the PiP, do they mention in what area?

LOS ANGELES (GM) – A Low Emissions Package that qualifies the 2012 Chevrolet Volt electric car to access California’s High Occupancy Vehicle traffic lanes will be standard on all models sold in the Golden State early next year.

"PiP kWh 3.6 kWh per charge

Volt kWh 12.9 kWh per charge"

Any source?

and what is the kWh per charge of Nissan Leaf?

Thank you.
