    While we can't rely on electric vehicles alone to break the dangerous, expensive oil monopoly, EVs are an integral part to opening up the fuel market. As technology improves, more EV and hybrid car options will become available to consumers, helping to save money and break away from the pump.

    Also, Nissan is launching this after April where Heat requirement is NO longer a big need, it will help range as well.

    Why doesn't he try the Leaf as a Taxi in the winter between Nov and Feb?

    According to the article, the trial is for 2013 Leafs. The 2013 model's heat pump is 2x more efficient than the old resistive heater, and heat is stronger and faster. Not sure if the heat pump can operate in reverse to cool the cockpit as well (to assist the A/C)

  • fb_1559222512 avatar Xiaolong Posted: 8/5/2013 4:25pm PDT

    Resistive heater is always nearly 100% efficient at all temperature. However, the Heat pump efficiency can vary a lot vs. temperature. When it is extremely cold, the efficiency will be lucky to be about 1.1 to 1.2 I seriously doubt the "2x" number.

    Technically speaking, heat pump can be reversed to work as A/C if designed correctly. Carrying two seperate system would be silly. But the tradeoff is the optimal point. If it works as a good A/C, then the heat pump doesn't do much below 45 degrees...

    "Compare that to his previous gas costs--around $50"

    So, at $4/gallon, he uses 12 gallon per day. @25mpg, he drives about 300 miles per day.

    "he pays around $11 a day in electricity"

    $11 @ $0.15/KWh is 73 KWh or 256 miles.

    So, he drives about 250-300 miles per day. For a Leaf with 80 miles range (city), that is at least 3 full additional charges or at least 4-5 quick DC charging per day or 2.5 to 3 hrs of wait time...

  • olden avatar olden Posted: 8/2/2013 2:00am PDT

    The guy is surely smart enough to start his day with a full charge. Only 3 refills to 80% are then needed to get to a total of 73 usable kW*h.

    That'd be 1.5h of DC quick-charging. Also, it's not like the driver has to attend the vehicle at all those times; he could go eat, etc...

    Far from being perfect yet, agreed, but nowhere near as bad as your initial assessment.

  • fb_1559222512 avatar Xiaolong Posted: 8/2/2013 1:34pm PDT

    But the worst is that a fare that come and needs to go farther than what is left in the range, what does he do? Refuse the fair and go charge?

    It is NOT an ideal situation. A larger battery would be much better.

    Plus, we haven't even included the winter mode yet...

    Although I like the idea of electric cabs and myself own two electric cars (Leaf and Focus), I am surprised that Leaf is being used as taxi. I am not a taxi driver but I imagine they (want to) put many hundred miles on the car per day, which is impractical for Leaf. What I fear is that people will try it and dislike it, due to limited range, which makes it a "failure" in public opinion. The main negative argument for EVs is the limited range and it doesn't help if passengers are denied the ride or are caught with a dead battery first hand.

    Tesla would certainly be a better choice, admittedly at a much higher cost. Why doesn't the company strike a deal with NYC and produce somewhat cheaper versions of the Model S at high volume for them?

  • fb_1775577382 avatar Doug Posted: 8/1/2013 7:26am PDT

    This is where induction charging would work really well. Pads placed under taxi rank lines and common pick up locations, would mean short top up charges could be had regularly without driver intervention. (think waiting at train, airports etc).

  • MorinMoss avatar MorinMoss Posted: 7/31/2013 7:47pm PDT

    It's a pity that Better Place didn't try or succeed in launching a large-scale EV taxi trial in NYC - what a showcase for electric vehicles and battery swap that would have been.
    It probably would have cost no more than $10-15 million for 100 cars and the chargers, swap stations, and spare batteries to support them.

  • fb_777648896 avatar Robert Posted: 7/31/2013 3:02pm PDT

    I would have liked to know a bit more info on range/charging. How many times a working day does he have to charge on a quick charging station? Say worse case he is getting in 3 to 4 hours per charge on a 10 hour shift. He would have to charge minimum 3 times. Two of those times would be during lunch break and dinner break. the third would eat up 30 minutes of fares. So how much does it cost him to charge up every time. I ask this cause the new cab Nissan Vans will have the same platform (but heavier I would guess) so fewer miles per charge? or will Nissan be squeezing a few more mile with new software?

  • leptoquark avatar leptoquark Posted: 7/31/2013 1:53pm PDT

    I just wonder how many times he has to (or would like to) DC fast charge per day. I like the idea of electric taxis, but in Hong Kong, drivers were not unexpectedly complaining that they took too long to charge on L2. I would expect two or three L3 charges per day would be about average.

    He ought to advertise on the outside of the cab that it has a super smooth, quiet and relaxing ride.

  • Nissanhater avatar Nissanhater Posted: 7/31/2013 11:48am PDT

    He's lucky he doesn't live in Southern Arizona. He'd be one of those "TINY" few whose battery would go South on him.

    Just sent an email to SEVERAL people connected to a NYC Mayors race warning them about NISSAN

    The range is bad... to taxi riders NOT want to get to their destination? Some might be stranded.

  • fb_1674635723 avatar Ralph Posted: 7/31/2013 12:23pm PDT

    @Sharyn: Why are you bashing Nissan Leafs? Are you an owner of a Model S or do you have any EV?

  • fb_100006040320683 avatar fb_100006040320683 Posted: 7/31/2013 9:20am PDT

    I don't know why New York didn't go with a Model S. Yes, it is much more expensive, but with the gas savings, it is worth it. The range and battery life is so much better it would be charged at convenience, not when necessary. Think: saving 40 a day is 15000 a year. In a year or two you will need a new Leaf battery, not with the Tesla! The saves make it worth the Tesla in this case.

  • fb_545537738 avatar Ramon Posted: 8/1/2013 4:42pm PDT

    Something about availability and production schedules and other factors I am sure factored in besides prices.
