What to expect from the BYD electric bus?
Iron-Phosphate battery technology
The power battery for an electric bus needs to meet exacting requirements for safety, energy density and low cost.
BYD’s safe, reliable and environmentally friendly long life Iron-Phosphate battery is the best choice to meet all of these demanding criteria. Under normal conditions, BYD’s Iron-Phosphate battery can retainover 75% of its capacityafter 10 years’ use.
The Iron-Phosphate battery contains no heavy metals or toxic electrolytes and with no pollution or emissions during the production process. Furthermore, the spent batteries can be recycled with minimal environmental impact.
The 12m BYD ebus is able to run 260km on a single charge in typical urban conditions. Two battery packs with a capacity of 270kWh can be mounted in various positions to enable flexible interior layouts and requirements. A further pack to provide enhanced range can also be installed. With the benefit of BYD’s research and development capability, the density and capacity of the BYD Iron-Phosphate battery is growing steadily every year.
Technical advantages
BYD’s in-house developed motor controller has integrated on-board charger controls which monitor the functions of the motor, allowing the driving motor to reverse the direction of current when required. The distributed Battery Management System consists of the signal collector and controller, which has the capability of constantly inspecting every single cell’s working status.
The BYD ebus also features a Regenerative Braking System. This system converts part of the kinetic energy during deceleration or downhill driving into electricity and stores this “bonus energy” in the battery providing additional driving range.
The BYD in-house-developed rear drive axle installed on the ebus is the core technology in the BYD electric buses. The rear drive axle system integrates the wheel-hub drive and regenerative braking technologies, and at the same time, provides exceptional passenger comfort.
In the ebus range, different body types, interiors and loading capacity can be tailor-designed according to customers’ requirements, and thus providing operational flexibility.
Designed to be corrosion-resistant for a service life of more than 20 years, the integral aluminum body not only delivers the lowest possible curb weight, but also ensures optimum performance while reducing energy consumption.
The 12m BYD ebus has received the EU’s Whole Vehicle Type Approval, WVTA for short, allowing it to be sold in all EU member states without the need for individual national approval. The energy consumption of BYD ebus is around 130kWh/100km in urban conditions.It saves up to 80% of the fuel cost when compared to a traditional diesel bus. The longer you drive, the more you will save.
With a distinctive appearance, the BYD ebus is in tune with the modern design style demanded by forward looking operators in the public transport sector. Many details, such as the clear and sleek lines on the front, the blue and silver oval logo and the alloy wheels, all accentuate the strong design identity. The ebus is available in a range of colours to meet regional operator requirements and livery styles.
On-board charging system
The BYD AC on-board charging system is a newly developed technology for an electric bus. The cost and space occupation are much less than that of an off-board DC system and the AC on-board charging system is also easier to operate.
Fully proven
BYD is now by far the world’s largest manufacturer of full size electric buses. The BYD ebus has been proven by millions of kilometres of passenger-carrying service in China and elsewhere.
BYD ebus has been tested worldwide inmore than160major global cities, including–in Europe – Madrid, Salzburg, Warsaw, Amsterdam, Barcelona, Brussels, Tel Aviv, Budapest and London; and–in the Americas–New York, San Francisco,Los Angeles,Toronto,Bogota,São Paulo and so on.
Each city received BYD electric buses to conduct their own programme of tests on operational cost-effectiveness and return on investment of the new technology. The encouraging test data and financial figures demonstrate the outstanding reliability and efficiency of BYD’s unique electric system.
The Dutch island of Schiemonnikoog has converted its entire bus fleet to pure electric BYD ebuses and a fleet of 35 units has entered service at Schiphol Airport, Amsterdam.
In Shenzhen, China, 780 ebuses have been delivered to Shenzhen Bus Group Company. By the end of August2015, the accumulated mileage was about83 million km, with that for a single bus being more than 0.27million km.
In July, 2015, BYDand Alexander Dennis Limited (ADL), Europe’s fastest growing bus and coach builder, formed a powerful new alliance and confirmed a £19 million deal that will see the introduction of London’s first large-scale, zero-emission, single deck bus fleet– 51 units of 12m single deck ebuses. This will also be the single largest fleet of full size electric buses in Europe.
In August, 2015, Denver’ Regional Transportation Districtin the USA announced to purchase 36 new BYD electric buses for mall service.
In September, 2015, BYD is awarded a “dominant” win in the Washington State Department of Transportation (WSDOT) Heavy Duty Bus RFP which allows for the purchase up to 800 pure electric heavy duty buses.
And many other purchases since then ….
BYD’s green dreams and strategy
BYD’s three green dreams
BYD has three green dreams: electric vehicles, battery energy storage stations and solar farms. The first dream of replacing conventional fossil fuel vehicles by electric vehicles to reduce emission and pollution is coming true gradually. BYD believes that replacing the use of fossil fuels – which will run out one day – is essential. Renewable and emissions free energy sources, particularly solar energy, will be key to the long term solution to the global energy crisis.
Green City Solution
BYD has created its Green City Solution aiming to electrify urban public transportation systems by transitioning from gasoline and diesel powered buses and taxis to pure electric ones. Besides electric vehicles, BYD also provides related services such as charging facilities, charging station monitoring systems and after-sale service, all-in-all a one-stop-shop solution.
