The BYD ebus (also: BYD electric bus ) is a line / city ​​bus in various expansion versions from the Chinese manufacturer BYD Auto . It is a pure battery bus and the world's first with a lithium iron phosphate battery . From the start of production in 2010 to April 2019, over 50,000 electric buses have been manufactured; this makes it the best-selling electric bus. It has also been used as a double-decker bus in London since 2016 .

history

A BYD double decker electric bus in London

The first BYD ebus (named K9 ) left the production facility on September 30, 2010 . The first effective media use of the model took place in 2011 on the occasion of the international Summer Universiade 2011 in Shenzhen . Since then, the 200 buses that have been deployed have been in regular service in the city. Today, electric buses of this type are used in a large number of other cities in China.

In January 2013, the EU issued a Whole Vehicle Type Approval for the BYD ebus , which, in addition to the declaration of conformity, enables it to be sold in all EU member states without having to obtain further approvals from any member state. The first line service in Europe operated exclusively with battery buses was set up in the Netherlands: since the beginning of 2013, six BYD buses have been operating on the otherwise largely car-free island of Schiermonnikoog . A larger fleet of electric buses in Europe is on the road at Amsterdam Airport Schiphol : 35 BYD battery buses operate as apron buses between the terminal and the aircraft. Since the mission does not require a long range, smaller batteries could be installed and the number of passengers increased. A charging station is available for each bus, which is fed by nearby solar panels . In the public tender in 2013 BYD was able to prevail against well-known European manufacturers.

In May 2014 BYD announced an order for 2,000 eBuses and 1,000 eTaxis for the Chinese city of Hangzhou . In October 2014, the BYD ebus was presented as an 18-meter-long articulated bus at an exhibition in the Texas city of Houston . The vehicle has space for 125 passengers and is considered the first battery articulated bus. In 2015 BYD was able to sell around 6000 ebus worldwide.

The first double-decker battery buses based on the BYD ebus have been in service with the London transport company Transport for London since March 16, 2016 . Until the model was presented, experts considered double-decker buses unsuitable for electric drives, partly because of their high weight. The city plans to procure around 300 of these vehicles by 2020, which in their typical red color are considered a symbol of London.

Also in London, the largest fleet of electric buses to date was inaugurated in September 2016. Since then, 51 battery buses have been operating on two lines. The vehicles are assembled in Scotland. BYD supplies the chassis as well as the drive (of the BYD ebus type ) and the Scottish bus manufacturer Alexander Dennis Ltd. the structure. Around seven million passengers are carried annually on the two lines. Like other major cities, London plans to ban diesel buses from inner city areas because of their noxious exposure to nitrogen oxides and noise .

In the middle of 2016 BYD Auto received a major order for the delivery of 2000 ebuses for the public transport of the city of Shenzhen . The order is valued at around ¼  billion US dollars . The city of 12 million plans to convert all regular services, which are still mainly carried out with environmentally harmful diesel buses, to electric buses.

BYD delivered a battery bus 18 meters in length and a 547 kWh battery to the USA in May 2017, with which the bus has a range of 440 km. The bus can transport up to 60 people. The bus battery can be recharged within two to three hours.

In April 2019 BYD presented the longest all-electric bus to date, the BYD K12A. The double articulated bus with a total of 4 axles, of which a second can be switched on as a drive axle, has a total length of 27 meters and can hold a maximum of 250 passengers. With an average range of 300 kilometers, this corresponds to 75,000 passenger kilometers . The engine output is 600 kW, with which the bus can reach a top speed of 70 km / h. In Germany the bus can only be operated with a special permit due to its length, as the total length of buses is currently limited to 18.75 meters in EC directives. The K12A is the first purely electrically powered bus with 4-wheel drive.

technology

The core of the vehicle is the lithium iron phosphate battery developed by BYD itself . According to the manufacturer, the stored energy is enough to cover 250 kilometers with the bus without charging. The energy is transferred to two wheel hub motors , brushless AC synchronous motors on the rear wheels.

Since electric heating significantly reduces the range, ebus' are also offered, which are specially designed for the climatic conditions of Nordic countries, with multi-pane insulating glass and additional heating; corresponding models are in service in Denmark and Finland.

costs

According to BYD, an ebus saves around 190,000 US dollars in energy costs, i.e. electricity consumption instead of diesel consumption, over a period of eight years. In 2012 the price for a BYD ebus was 380,000 euros, around 100,000 euros more than a comparable diesel bus.
