An emblematic action in the mySMARTLife project is the replacement of the current Busway line (BHLS) fleet with 22 fully electric buses by the end of 2019. This action will take place on a heavily frequented bus rapid transit line which has reached its limits (43 000 passengers/day) with high frequency (one bus every 2,5 minutes at peak hours).
Analysis will be done on the impact of a large capacity electric bus (24 m, 150 passengers, up to 55 000 passengers/day) on the grid and on the reduction of energy use, noise and pollutants.
Twelve charging stations will be installed for the e-buses, as strong impact is expected on the grid. To alleviate it, charging stations located at certain stops along the line and at the bus terminus will allow energy transfer from the electrical network to the batteries of the vehicles. The energy transfer between the vehicle and the charging stations is carried out by an articulated arm located on the roof of the bus with a smart energy management system of "opportunity charging" (called TOSA). The bus equipped with the system recharges quickly on the passenger exchange time at a bus station (2 seconds for connection, about 20 seconds for charging) and at the terminus (a few minutes) with a power of 600 Kva.
In addition for e-cars, 90 smart charging stations will be installed until the end of 2020 and connected to Nantes’ engagement portal to provide information such as availability and location to users. For e-bikes, their overall number will be dramatically increased. By 2020, around 1,500 e-bikes will be available for long-term rental and 200 electric plugs will be installed in bike lockers and bike parking.
