BYD and New York Metropolitan Transportation Authority (MTA) Complete a Successful Pilot of BYD All-Electric Bus
NEW YORK--Jan. 9, 2014: BYD and the New York Metropolitan Transportation Authority (MTA) have concluded a pilot test on a BYD 40-foot, zero-emissions, battery-electric bus. The test period was from Aug 25th to Oct 25th totaling two months in service and the final report data has been summarized for distribution. “The general purpose of the program was to evaluate how an electric bus could perform in New York City’s heavy traffic, whether the electric bus can meet the twin challenges of operating in the stop-and-go traffic of Manhattan while maintaining high levels of passenger comfort and operational performance,” said MTA’s spokesman Kevin Ortiz. The bus tested at MTA was supplied by BYD Motors, based out of Southern California, and offers a range of 140-155 miles average between charges. Charging is intended to only be completed at night during off peak hours to reduce unwanted demand on the grid, and takes only 3 to 4 hours to return to full capacity. BYD Motor’s President, Ms Stella Li stated that she was, “delighted to see the vision and leadership of the New York MTA” and believes “that electrified transport solutions will bring about not only an economic recovery for the region but also an environmental recovery – we are committed to supporting these great leaders.”

The testing was carried out on different routes throughout Manhattan, including M20, M42, M104, M98, M60 and Bx27. The total distance covered during the trial was 1,481 miles. The BYD all-electric bus “performed excellent” with an average battery consumption of 1.4 miles per % SOC, translating to over 140 miles per full charge in heavy traffic. The average speed of electric bus was ~4 miles per hour under Manhattan’s heavy traffic. After two months of running, the electric bus’s average battery duration was 0.3 hours per % SOC, translating to 30 hours of operation per full charge, as opposed to other competitors that require en route recharging every 2-3 hours during peak-rate times. These uninterrupted operational hours are more meaningful in a busy city like New York, as routes and speeds travelled tend to be short in distance but long in duration. When contrasted to Diesel bus technology, BYD’s electric buses are far more efficient in energy consumption because Diesel engines are still idling when in heavy or stopped traffic. “This test continues the MTA’s commitment to examine newer, cleaner and more efficient bus propulsion technologies,” said Darryl Irick, President of MTA Bus and SVP, MTA NYC Transit’s Department of Buses.
BYD Electric buses provide several advantages over conventionally powered buses;
Improved air quality and reduced green-house-gas (GHG) emissions. BYD buses that are connected to power-interfaces can dispatch power back to the grid (bi-directionally) in case of an emergency or for optimized grid utility. BYD buses do not have an internal combustion engine or transmission and many other conventional components, therefore much less has to be replaced or refurbished every year reducing maintenance costs (and labor) significantly. Regenerative braking recovers braking energy, recharges batteries and reduces normal brake-pad wear and maintenance. Expected operating-cost-per mile of an electric bus is ~$0.20 to $0.30, compared to $1.30 per mile on an equivalent diesel or natural-gas powered bus in New York.
In April of 2013, BYD was awarded a $12.1 million contract with California's Long Beach Transit Authority to produce 10 zero-emissions, all-electric buses. Then in June, the Los Angeles County Metropolitan Transportation Authority (LA Metro) announced a contract with BYD for the manufacture and delivery of up to 25 of the same battery-electric buses. The contract is part of the county's $30-million clean air bus technology pilot project.
