Mitsubishi's Concept CA-MiEV 300 Kilometer range ..

    Taken from Autoblog

    The Concept CA-MiEV – where the CA stands for Compact and Advanced – is supposed to be able to go 300 kilometers (186 miles) from a 28-kWh lithium-ion battery and lightweight 80-kW motor/inverter/charger unit. This is kind of astonishing, given the range estimates of other compact and midsize EVs on the market today – most are in the 80-100-mile range. Of course, the specific test used to get the 186-mile result matters, too, since the regular i received 98 miles on the LA4 driving cycle range. The US-i has a 16-kWh pack.

    The increased distance means that Mitsubishi is talking about the Concept CA-MiEV as the "suburban EV," with enough range for "about one week of driving for an average European driver." If you need more, Mitsubishi hints that the flat battery pack leaves room for a range-extender. Add in convenience features like WiTricity wireless charging and the ability for the car to send an emergency email if it's stolen, and you've got the commuting vehicle of the future. With a coefficient of drag of just 0.26 and boomerang lights, of course.

    Ill hold my praise till its a production car independently tested! Lots of fanciful concepts over the years.

    It would suggest being 60% more efficient than LEAF if it is supposed to get such range from quite a small battery.

    28kw/h battery, hmmmm the Nissan Leaf has a 24 kw/h battery 21 usable.

    would have to be a "lot" more efficient than the Leaf, which is already fairly efficient, especially the update due in a few months.

    Rumour has it that it will feature hub motors, meaning no gear reducer, no drive shafts just straight power to the wheel.

    There would have to be a good reduction in weight and that will mainly come from a higher energy density battery and currently the next generation chemistry called NMC will offer higher density than that of the battery in the Leaf or Volt, I-mev etc.

    Leaf II is rumoured to have NMC and will most likely have a real range of 150 miles at 60-65 mph, however it could be more or less and that depends on a few things.

    Currently the only thing stopping us having a 300 mile range car is cost, think Tesla model S 85 kw/h battery. But that is a massively powerful car.

    So depending on cost, that will no doubt dictate the range of future electric cars. Tesla currently offer U.S buyers (not sure outside U.S) an option to buy a brand new battery in 8 years for 8,000 US Dollars for the 60 kw/hr battery, not that's a substantual reduction in cost, or maybe it's the projected future cost.

    I'll say it time and time again, we don't need a 300 mile range E.V because what's the point in carrying around a big, heavy expensive battery you will rarely use ? what we need is a real 100 mile range at 60-70 mph and can recharge that 100 miles in 5 mins or 10 max, that will be the greatest change in electric cars, that and longer lasting batteries.

    We also need a program so that when electric cars batteries reach 75% renaming capacity you can trade it in for a brand new pack unlike what nissan offer which is to replace modules. in other words if your Leaf battery is only getting less than 75% range they will only ever replace modules so that you will be at 75% or greater. Still if it's cheap enough it might not be so bad but they are keeping very quiet about the cost of replacements. But that could be because the price has come down a lot in the last 5 years or so that they just can't say.

    What do you mean ? small battery ?

    I mean 28kWh is equivalent of roughly 9 liters of petrol (ICE inefficiency included) which would make it rather hard to easily reach 300km in real world. If Mitsubishi could make 3l/100km decent five seater, it would already happen.

    I still believe a real 100-150 miles @60-70 mph is more than enough and would help greatly to reduce the cost of batteries.

    It's not a problem if there are as much fast chargers as petrol stations and that's exactly what we need. Along with ultra fast charging.

    I got to think how many times I've driven 300 miles in one day and I can't think of when because I never have, so why would I want to buy a car that has a battery costing 3 times as much as I need, or ever likely to need ?

    If I know I can fast charge in 5-10 mins and put back a real 100 miles range then that's good enough for me and most of the planet.

    But we're talking 40 kw/hrs that's the barrier, that's the breakthrough we're waiting for. It's just a matter of cost. And one of the reasons Tesla went with cheap readily available already mass produced laptop cells.

    I think the Model S can fast charge at 110 kw compared to the Leaf at 50 kw, so if the Leaf could charge in 5 mins to 80%, then I could very easily live with that, provided the battery had twice the life span.

    If Nissan offered a battery recycling program where they will give you a new battery for a reduced cost and give them the old one, that would put many minds at ease because currently, if your battery reaches 75% Nissan will not give you a new one and will not repair the old one until it drops below 75% and they can if they want only bring it back to 75%. Nissan say a battery is good up until 75% remaining capacity, I say up yours Nissan if you think I'll accept a car that has 75 mile real range with 50 miles real range after 80,000-100k miles.
