Go-Ahead Singapore BYD Electric Bus Trial

Go-Ahead Singapore trialed Singapore’s first fully-electric bus, a BYD K9, to assess the suitability of e-buses for public transport, in a pilot which could see more of such green vehicles being used for mass transport. Initiated by the Land Transport Authority, the electric bus trial operated on 3 bus routes, 15, 17 and 119, from November 2016 to May 2017.

The e-bus trial was part of the EV test bed led by LTA and the Economic Development Board to trial fleet-based EV operations, a follow-up to the earlier phase which ended three years ago and involved individual corporate users. The LTA also added that the bus will operate trips on top of those scheduled, and hence will not cause an adverse impact on service levels.

Charging equipment and infrastructure were installed at Go-Ahead‘s depot in Loyang. to support operations of the e-bus. The K9 bus requires between 5 and 10 hours to be charged fully, allowing it to run for 250km, but its range could be lower due to the warm climate in Singapore, with additional battery power used up for cooling.

Registered as SG4001J with the chassis number LC06S24S7D0000004, the trial unit was earlier spotted parked in NTU for inspection in 2015. The bus was then shipped to Jakarta for a short period of time before returning to Singapore.

      LTA should have kept this bus. And deploy it as perm with Go Ahead Service 84.
