The BYD B series are a line of battery electric buses produced by Chinese vehicle manufacturer BYD. It is the first bus model powered by BYD's Lithium Iron Phosphate Blade electric-batteries. It is available as a 10-metre single-deck (B10), a 11-metre double-deck bus (BD11), a 12-metre single-deck (B12), a 12-metre tri-axles double-deck (B12D), a 15-metre tri-axles single-deck (B15) and a 18-metre articulated bus (B18). ^{[1] [2] [3]}

History

The BYD B series was launched on 29 July 2020, superseding the highly popular BYD K series. The bodywork was designed by Wolfgang Egger. ^[4] According to BYD, the new bus models feature LED water lamps, USB charging ports, newer-generation wheel hub motors which are 6% more energy-efficient, as well as a lightweight aluminum frame reducing the body weight by up to 10%. ^[1]

Asia Pacific

• Hong Kong:
  • 16 BYD B12A buses entered service with Kowloon Motor Bus in 2022. These electric buses are the first B series buses built to right hand drive specifications. ^{[13] [14] [15]}
  • 41 BYD B12D buses were also delivered to KMB in 2023. These buses were first deployed on route 213M in July that year. ^{[16] [17]}
• Japan: 2 B10 units entered service with Keihin Kyuko Bus in 2024. ^[18]
• Indonesia: 30 B12As were delivered to TransJakarta in 2022. ^{[19] [20]}
• Singapore:
  • In November 2022, ComfortDelGro took delivery of several BYD B12A03 buses with three doors, to be used on Internal Shuttle Bus services (ISB) within the National University of Singapore and Nanyang Technological University. These buses, along with Zhongtong N12 buses which entered service earlier, will gradually replace all diesel-powered buses on ISB routes. ^{[21] [22]}
  • A BYD B12A03 Single-deck Bus, also featuring three doors, was showcased at the Singapore International Transport Congress & Exhibition 2022. ^{[23] [24] [25]} After the exhibition ended, the bus was modified, repainted and entered service under SBS Transit on 14 January 2024. It was registered as SG4013A. The bus is deployed on services 70, 70M, 138^*, 162 and 265. ^[26]
  • On 25 November 2023, the Land Transport Authority (LTA) announced that it had awarded a contract to BYD to purchase 240 3-door BYD BC12A04 buses, with an option for 60 more exercised in October 2024. They had entered revenue service on 2 December 2024, ^[27] deployed on bus routes 80, 86, 107, 107M, 116 and 159.
  • A new BYD BC12A05 (marketed as the B12DS) electric double-deck 3-door 2-staircase bus made its debut in SITCE (Singapore International Transport Congress & Exhibition) 2024. This B12DS bus was specially designed for the Singapore market, with bodywork by Zhuhai Guangtong Vehicle Manufacture. It may be accepted as a trial bus by the Land Transport Authority, due to its vision of having half of the public bus fleet to be electric by 2030, and its recent preference for double-deck buses to have the 3D2S configuration. * The bus was not approved on 138 by LTA due to the third door not being able to fit in the bus stop.

Europe

• Finland: Nobina ordered 42 B15s for service in Turku. ^[28]
• United Kingdom: BYD BD11s entered service for Transport for London (TFL) in December 2024. ^{[29] [30]} Additionally, B12 single-deck electric buses have also been made to TfL specification and are due to enter service. ^[31]
