Electric buses @ BYD ebuses [VIDEO]

BYD Company Ltd. is one of China's largest companies and has successfully expanded globally. Specializing in battery technologies, their green mission to "solve the whole problem" has made them industry pioneers and leaders in several High-tech sectors including High-efficiency Automobiles , Electrified Public Transportation, Environmentally-Friendly Energy Storage, Affordable Solar Power and Information Technology and Original Design Manufacturing (ODM) services.
Long Beach Transit Board of Directors voted to recommend BYD Motors as the provider of 10 full-electric buses for Long Beach, CA, a city 30 miles south of Los Angeles, CA. On the last day of Governor Brown’s visit to China he announced that BYD buses will be assembled in Lancaster, CA. On May 1, 2013 there will be a grand celebration in Lancaster, CA.
The BYD electric bus or BYD ebus, called K9 in China, is an all-electric bus model manufactured by BYD powered with its self-developed Iron-phosphate battery, allegedly featuring the longest drive range of 250 km(155 miles) on one single charge under urban road conditions. BYD electric bus rolled off line on September 30, 2010 in Changsha city of Hunan province. This pure electric bus is another renewable energy vehicle by BYD following its models like F3DM, F6DM and e6. The K9 has a 12-meter body length and 18-ton weight with one-step low-floor interior for passengers' comfort, reportedly priced at 2–3 million yuan (S$395,000 - S$592,600). It has been running/tested in China and many other countries and regions such as Hong Kong, U.S., Colombia, Chile, Spain, Netherlands and Denmark. More than 200 BYD electric buses, in public transit service in Shenzhen China, have accumulated over 9,216,000 km (or 5,529,600 miles) by the end of August, 2012.

BYD claims no emission, no pollution from its electric buses and the chemical materials contained in the battery can be recycled without any toxins. As for the power system of this pure electric bus, BYD's self-innovated in-wheel motor drive system which realizes the function of in-wheel motor drive and hub reductor. The max power output is 90 kW*2 and the max torque is 550Nm*2. Solar panels fixed on the vehicle were once reported to provide more power to supplement the on-board batteries and they really were included on BYD's demo units but not those that have been running on the road commercially, such as in Shenzhen and Xi'an for instance.
