BYD eBUS-12 – Click above to watch video after the jump

BYD has big plans to bring its vehicles to America, and while we will likely have to wait until 2012 to see the F3DM hybrid or all-electric e6 in showrooms, the company's 12-meter (39.37 feet) electric bus should arrive later this year. Yes, we said bus and later this year.

Apparently, BYD bought the Hunan Midea bus company not long ago and has since developed the electric eBUS-12, which includes some interesting tech and performance specs. Launched last September, it is already in operation in three Chinese cities and the company has orders from Hunan province for 1,000 units.

American plans for the BYD behemoth have it making a grand entrance at an upcoming Berkshire Hathaway shareholders meetings in Omaha. The company is reviewing a dozen potential cities and says it expects to have buses testing on the road before the end of the year.

The bus itself is said to be good for 300 kilometers (186.4 miles) optimally – 250 km (155.3 miles) with more typical urban usage – and has a 60 mile per hour top speed. Propulsion is provided by in-wheel motors and solar panels populate the roof. A full charge of the 324-kWh lithium iron phosphate battery takes a little more than three hours with 100-kW charging equipment, though with the optional monster 600-kW proprietary rapid-chargers, it can be done in 30 minutes. Hit the jump to check out some BYD eBUS-12 action for yourself (starts at 1:30 mark).

      For those in the rapid charge battery article assuming 100kW charging is too much, this already has it. It has up to 600kW charging!

      324-kWh is a huge battery pack.

      I'll pass. No offense, but the production quality of Chinese goods, specifically cars and their already cracking high speed rail network, is downright pathetic.
      • 7 Months Ago
      BYD's modus operandi seems to be cram a ton (literally) of batteries in an EV and claim amazing specs (that lower as it nears production) yet a reasonable price. They can do this by taking batteries from themselves and foregoing enormous profits on the open market, but as we've seen with the e6, the resulting money pit gets made in tiny quantities mainly for PR purposes. I wonder if BYD owns the bus lines in those Chinese cities as it does the taxi company that runs all the e6s.

      A 324 kWh battery pack "50 percent charged with BYD’s rapid-chargers in 30 minutes" means over 324 kW from a DC fast charger, 5 times CHAdeMO maximum power. I smell more exaggeration from BYD.

        "A 324 kWh battery pack "50 percent charged with BYD’s rapid-chargers in 30 minutes" means over 324 kW from a DC fast charge"

        That 50% in 30 minutes claim is from the source article. As per my post, it actually does better than that with their 600 kW charger, filling the battery in 30 minutes. 600kW X .5hr = 300kWh.

      If I calculate correctly, these 250 km are enough for a full working day - well, if the value is realistic.

      So instead of 75l diesel you will then need 100 kWh electricity for a day. With German prices this makes about 75€ saving per day (maybe differs a bit, as taxes for commercial use are a bit different).

      Let's be very optimistic and give this 25 days per month and 10 years to life. Makes quite massive 225.000€ saving, BUT such a 100 kWh battery is *damn* expensive...
        • 7 Months Ago
        On many bus routes, the bus sits idle for 15 to 30 minutes at the end of the route before turnaround. That would allow time for a partial recharge, thus increasing the useful daily range.
        • 7 Months Ago
        ..this also makes the whole cost calculation useless: You only save 25€ per day or 75.000€ over the whole 10 years.

        This now with the $40.000 per 100 kW battery makes ~85.000€ for the battery.

        So this one will be a loss, if all these numbers are correct.

        Average speed in cities are 15 km/h; so these are nearly 17 hours. No need to worry so ;)
        • 7 Months Ago
        Eh, correction.. 300 kWh (3h at 100 kW...)
      • 7 Months Ago
      First product from China that sounds interesting.
      Yes, battery placement needs to be rethought.
        • 7 Months Ago
        I am sure you are concerned about the high center of gravity with the batteries mounted high. But this is not a race car. Their concerns are a low floor for easy entry and exit. In buses it is difficult to arrange seating over the wheels, so putting the batteries here in a location where there are no seats anyway is smart. Also the battery load is directly over the wheels so the weight does not have to be supported over a long span. I am sure this arrangement still has a lower center of gravity than most big loaded trucks.
        • 7 Months Ago
        You are mixing center of gravity with weight balance.

        All (boxy) buses have center gravity around the middle of the bus. The only way to lower it is to lower the height of the bus.

        But roll is (also) defined by the top heaviness of the bus. Heavy weights placed above the suspension level adds to the roll of the vehicle.

        Its quite amazing that they placed the batteries near the wheels to reduce engineering complexities. But placing the batteries on the floor would not added too much of weight to the bus either. The bus is already designed to carry about 12 tonnes of weight(loaded). Designing the bus from ground up to hold the batteries in the floor(under seating row) might have actually saved some weight. But would make the bus quite expensive. Though I dont think a bus with 300 KWh LiPo batteries will be cheap either.

      The commentator in the ad is awesome... It's not BYD... It's BEE-WYE-DEE!

      check out the layout for the batts. Not the location I would have guessed.
      • 7 Months Ago
      I measured some bus routes here in Vancouver, at being around 20 km, and I know these buses stop in locations where it would be easy to install a CHAdeMO charger (for a partial recharge if needed), but then again, we already have trolly buses here that run off of electricity. I can see this bus though for other routes that don't have the overhead wires set up. Those trolly wires are an eyesore, so I would be nice if over time they could get rid of them with a bus like this.

      That video had nice visuals, but having to hear BYD over and over again, was hilarious.
      • 7 Months Ago
      A 100kWh battery shouldn't be more than $40,000 for BYD.
      • 7 Months Ago
      Hope you liked your Photoshop Video.. it wasn't real the products won't be here until 2012 hasn't done its cold testing in Denmark yet.


      oh well another pre-release press announcement..
      • 7 Months Ago
      Im interrested to buy because it have a solar panel on the roof. But not that size, im talking more for a 4 of 5 passengers cars but also with solar panels on roof. I don't care if it's made in china and it cut jobs in n-america, anyway america have long time ago say no to anything not gasoline for cars and motorcycles and light trucks and diesel for trucks and tractors. No efficient and attractive and convenient and cheap priced cars for north-america done by bush, obama, clinton, wall-street traders, world trade center demolition crew, gm, ford, chrsler, tucker, jeep, amc, harley-davidson, polaris, bombardier, artic cat, massey-furguson, brigg and stratton, etc.

        You have been nominated for the DF, Grampus fanciers cracker barrel basket weaving and whittlin' club. (bring own lunch) .

        Your attendant can drop you off and Anoraks mum will pick you up.

        What colour bus would you like to buy? Matchbox or Mattel?
      • 7 Months Ago
      kl, thanks for the try. I'm thinking though that your bus mileage is off. Please indulge me while I go through this in numbers I understand. :)
      You used 75 liters (19.8 gals US) example to cover 250 km(155 miles) which translates to 8 miles per gallon of diesel. A quick google search indicates more likely 4.3 mpg average or so in urban use.
      155/4.3 = 36 gallons/day x $4 = $144.
      324 kwh x $.13 (assumes my high residential rate) = $42/day.

      So, that looks like a savings of $102/day x 6 days x 52 weeks x 10 years = $318,240 in fuel savings. Hopefully, maintenance would be considerably less as well.

      Feel free to correct any bonehead errors here...

        And of course, nobody talks about heating and cooling.
