Sao Paulo Transit Completes Successful Trials of BYD Electric Bus; Orders Two For Now

BYD announced that Sao Paulo Transit (SPTrans) ordered two battery-electric buses, which will be delivered in March 2014.

These electric vehicles will join 20 ICE buses currently operating on Line 509M in Sao Paulo, Brazil, where SPTrans has a fleet of over 16,000 buses (a lot to electrify eventually).

According to BYD, the pilot program proved that the BYD electric bus was effective on over 80% of routes currently in operation and has an average range of 250 km (155 miles).

João Carlos Fagundes, SP Transit Engineering Division Manager stated:

“Our tests were designed to demonstrate the performance of the e-bus running on the streets of Sao Paulo, such as its braking performance and so on. The electric bus was filled with a weight equivalent to a full load of passengers and run on bus lanes and other designed lines in Sao Paulo,”

    Great. Love electric buses.
    – Emission reductions equal to those of many electric cars
    – No pollution right where it’s more important (cities)
    – Great advertising for EVs in general (lots of people come to experience how comfortable electric drive is).

    Same for electric taxis.
    I think BYD is focusing on the right areas.

    In some cities (Shenzen, Bogota, ?): both BYD e6 taxis and BYD e-buses.

    My view: Nissan should offer the taxi version of its e-NV200 with twice the pack of the standard version (so, some 48 kwh). Would it work, technically (space and weight-wise)?
    The vehicle in itself is ideal as a cab (adopted in NYC, as most of us know), but in my opinion you need a greater range (also in view of battery degradation). It should not cost much more, per mile driven, since it could be driven for at least twice the miles, in the life of the taxi.
    And the cost will be double only for the battery. The rest of the car would cost the same, and you’ll use it for twice the miles. Wouldn’t it be even cheaper, in cost per mile, while, at the same time, offering the great advantage of a bigger (almost double) range?
    In particular in expensive-gasoline Europe, savings will be so big that it will repay itself fairly soon: €18,000 extra for the 48 kwh batteries, savings of about €0.16 per km (it’s a fairly big vehicle). Payback after about 112,500 km! (It’s just one or two years for most taxis). That means only about 500 cycles (another advantage of having a bigger battery) and, probably, still 90% capacity.
    With the smaller battery it would have taken about 1,000 cycles.

    Will it make sense to place fast chargers along the main routes departing from the city, in all directions, at every 50 miles or so? Or charging times for these batteries are anyway too long for this to work for a taxi (so, you’ll need to do with a longer range and no on-the-go recharges)?
    A big difference would anyway be made by the possibility to have a fast charge in or outside the city at mid day or so, with no time losses (while the driver is having lunch).

    BYD battery has the big advantage of lasting much longer (thousands of cycles with minimal losses). That could make the difference. But with a bigger battery pack… Or maybe Nissan should try to get batteries from BYD? They’re heavy, but great for all other aspects. Should BYD sell them to other automakers?

    I like pure EVs, but, in some cases, a range extended version (but with 24 kwh, if not 48kwh battery, for taxis driving long distances per day regularly) might be the most practical and economic solution. One has to make specific calculation for the specific cases, of course.

    What do you (all) think?
    If someone from Nissan reads this… (or someone passes it on, if he think it makes sense).

    1. Alok says:

      Even a 72 kwh battery should be considered. Much longer range at no extra cost per mile (since it lasts much longer).

      Actually, even a Model S would make sense, here in Europe. Much better a Model X. Ideal.
      Here in Germany, many taxis are quite big Mercedes, maybe just €25,000 cheaper than a Model S (60 or 85). With savings of about €0.16 per km, you break even after about 160,000 km (100,000 miles).
      You can drive some 4-500,000 miles in a Model S without replacing batteries (of course, it can be much more if range will still be enough for you). So, if you would drive the same with the Mercedes, at the end you would have saved some €75,000 or more! (on top of having recovered the €25,000).

      Now, let’s compare a 85 Model S with a non plug-in Prius. Sorry for that…!!!
      “Cost” difference: 80,000-27,000= €53,000
      I think the cost of financing these extra €53,000 can be considered to be compensated by the increase of the cost of gasoline in a 8-10 year period (even at just the average inflation rate).
      “Cost per km” difference (incl. maintenance): 0.09-0.04= €0.05 (at current prices. Much more in future, just because of inflation).
      That’s €0.08 per mile.
      After 500,000 miles (around 10 years for an average taxi?) (less than 2,000 cycles for the 85 S) you would have saved some €40,000. So only €13,000 missing. But would have the Prius survived 500,000 miles without big expenses?

      Even in that case, with the S you could get a new battery (what’s the cost Tesla mentioned for the replacement? Anyway, not much some 8-10 years from now) and drive another 500,000 miles! (Or sell the car for a good price). Let’s take advantage of the great reliability of electric motors!

      So, we could say, you don’t spend anything more (maybe you would even save money), and you would have driven a Model S!
      Therefore, if a were a taxi driver, for me the 85 Model S would be a no-brainer (if I had the possibility to get the financing).
      I would not consider a 60 Model S: the €10,000 more for the 85 will be well repaid by the extra miles I’ll be able to drive, with the huge advantage of the longer range available every day.

      Does this make sense? I know, it seems too good to be true. But that’s the power of electric drive! (and more than right taxes on gasoline…).
      And we’re not considering any subsidies!
