BYD unveils electric over-the-road coach bus


While several companies are building electric city transit buses, China-based BYD has unveiled what it calls the world’s first electric over-the-road coach bus. The BYD C9 is a two-axle, 40-foot two-axle coach with a seating capacity of 47, top speed of 62.5 mph and range of over 190 miles.

“The transportation industry is still just warming up to the idea of battery electric transit buses,” said BYD VP Macy Neshati. “It was exciting to walk around last year’s APTA Expo in Houston and see so many reputable names displaying an electrified transit bus. However, I don’t think anybody thought they would see a viable electric coach solution for a few more years.”

The C9 uses BYD’s in-wheel drive axle with two 180 kW brushless AC synchronous motors, each of which develops 1,500 N·m (1,106 lb-ft) of torque. The 365 kWh Li-ion iron phosphate battery pack can accept 200 kW charging, for a charging time of less than two hours. BYD projects that battery capacity will remain above 80% after 12 years of use.

The C9 is the first of three battery-electric coaches the company plans to launch globally this year. The other two, a 45-foot three-axle coach named the C10 and a 23-foot coach with executive and transport configurations named the C6, will arrive by the end of 2015, and BYD says it is now taking orders for all three models.

“Last year, BYD pulled away from the competition in the transit space when they launched a 30-foot low-floor bus and a 60-foot articulated bus in addition to their 40-foot bus, making them the only electric bus builder with multiple offerings. This year the launch of three coach buses puts BYD on a level with no other bus or coach OEM,” said Neshati.

    This is just simply not true. Adomani had the first over-the road bus and it had a top speed of 82mph and could go 45 miles on a very small battery pack.
    The Adomani 40 foot all electric 50 passenger bus could also go up steep hills with no problems. Brand new bus for under $500K. The press was contacted about this information from Adomani LAST YEAR! Blue bird engineers are also very aware of this Adomani bus and rode in the Adomani all electric buses several times.

      Thanks Ed.
      I will look this up. Adomani deserve credit if they got there first.

      I hope this doesn’t come off as quibbling, but when I think “over the road”, I think driving at least a couple of hours at highway speed. I don’t mean to take anything away from Adomani’s achievement, but 45 miles isn’t a touring coach.
      With the right EVSE available, this could easily run a Greyhound schedule for hundreds of miles a day.

    I want one converted to RV.

    Yes, I apologize…it does say “touring” and the comment should be pulled from that technicality. Adomani has really only proven a concept that it can do the same thing for possibly a lot less money.
