7+4 – BYD Helps Transform E-mobility

Context of Transport Climate Action

BYD (Build Your Dreams) founded in 1995, is a listed company on Hong Kong and Shenzhen Stock Exchange. It started in IT industry and rechargeable battery business, (including handset, computer components and assembly services) and has expanded into the automobile business since 2003.

In BYD’s mid to long-term strategy, the company plans to provide a wide variety of electric vehicles, including buses, taxis, passenger cars and forklift trucks as the transition to electric mobility (Emobilty) can only take place if there are affordable and reliable vehicles in the marketplace.


Transport is the source of significant GHG emissions, especially CO2, and is one of the sectors where emissions are increasing rather than decreasing. It is also clear that demand for transport will grow, primarily in the developing world as they build their economies. Therefore in order for this growth to happen in a sustainable fashion, respectful of the climate and of societal needs, electric mobility will need to be scaled up. E-mobilty is almost emission free, if the indirect emissions from the production of electricity are not taken into account (Scope 3 emissions), so it can provide the high levels of mobility that is required for both passenger and freight.

BYD has developed a ‘7+4’ strategy, to produce electric vehicles for almost all the conventional and specialized vehicle markets.

The 7 stands for the 7 conventional vehicle areas that BYD will focus on: Transit Buses, Coaches, Taxis, Logistics Vehicles, Construction Vehicles, Waste Management Vehicles and, Consumer Vehicles.

The 4 stands for the 4 specialized vehicle fields that BYD will focus on: Warehouse Logistics Vehicles, Mining Utility Vehicles, Airport Utility Vehicles and Sea-port Utility Vehicles.

A key challenge for many cities to shift to using new vehicles and especially new fuels are both technical and financial. To address this BYD have developed an innovative business model that is being tested in more than 40 cities in Europe and the world. The capital investment of a bus, for example, is agreed between the city authorities, the operator and BYD and the vehicle is tested in the actual environment, running in service. The capital investments are offset by the gains in energy savings and the lower cost of using electricity as a fuel and solutions to any the technical aspects can be jointly solved. This helps speed up market uptake, allows the city to trial suitable vehicle in a low risk environment and also helps to build trust between parties that are new to working together.

BYD is supporting several of the Climate Change transport initiatives as part of this strategy to build the e-vehicle market. These include the UEMI, Urban Electric Mobility Initiative led by UNHABITAT and the Wuppertal Institute and the C40 led Clean Bus declaration.


To date (2015) BYD has supplied more than 3,000 buses, 5,000 taxis globally.

Examples include:

In Shenzhen, China, 780 ebuses have been delivered to Shenzhen Bus Group Company. By the end of August 2015, the accumulated mileage since 2010 was about 83 million km. Looking, therefore, more than 0.27 million km, 18.7 million kg CO2, per single bus has been eliminated or avoided.

One of the first examples of converting the whole bus fleet to electric propulsion in Europe can be found on the Dutch island of Schiemonnikoog. The entire bus fleet of 6 units switched to pure electric ebuses in Apr 2013.

Using ebuses in airport environments also makes a lot of sense, as there are usually significant local air quality issues at airports that need to be addressed as more pollutants are emitted during the take-off and landing of aircraft than while in-flight. A fleet of 35 units has entered service at Schiphol Airport, Amsterdam, one of the first in Europe.


As E-mobilty is almost zero emission free there are significant benefits to shifting to electricity for vehicle propulsion. Benefits include lower GHG emissions, zero local emissions (especially NOx) and reduced noise , as electric motors are much quitter than conventional Internal Combustion Engines. .

In addition to helping to preserve the environment and reduce air pollution, lowering operating costs is another innovative benefit. For example, in normal urban conditions the energy consumption of the BYD electric bus is around 130kWh/100km. The pure-electric bus saves up to 75% of fuel costs compared with a diesel bus.

In Shenzhen, each BYD pure-electric bus saves more than €19,000 and 42,000 liters of oil per year. The longer distance driven, the more cost saved.

This helps to provide greater national energy security for countries that do not have their own sources of fossil fuel. Addition operational benefits include reduced maintenance costs and the longer operational life cycle of electric motors, reducing the need for importing spare parts.

One of the major challenges for E-mobilty is still range anxiety (i.e. worrying about the distance able to be driven on a single charge). The range of BYD’s electric bus is presently at least 250km on a single charge, giving adequate service mileage for many urban routes.

Using ebuses is now feasible in most urban areas and provides a good solution to the majority of transport needs in current urban settings, especially where local pollution is a key concern.

Potential for scaling up

The potential for scaling up is already being seen. The sales of new energy vehicles in 2014 increased 9 times compared with 2013 according to CAMM (China Association of Automobile Manufacturers).

BYD ebus has been tested worldwide in more than 160 major global cities. 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 ambition of BYD is not only to provide buses. It’s about transforming the whole of Emobility in society and moving it towards more greener, electrified vehicles. E-Refuse vehicles, E-tipper trucks, E-Street Cleaners, is where we are going, but before that we already have our E-taxis and E-Forklifts. Without having the vehicles on the streets and having the hundreds of millions of kilometres logged, how do you know how good your product is? We have learned our lessons, for example we have two buses being tested in London on the 507 and 521 routes.’
