Volvo Electric Buses in Sweden
On 13th December, 145 Volvo 7900 Electric Articulated buses began operating on the streets of Sweden’s second biggest city. The new buses will be a big change to Transdev’s operations in the region, overnight, nearly half of its fleet will become electric. The buses, which operate on 34 different routes, will be charged at charging stations at end stops and via cable in the depots during the nights. To ensure an optimal charging infrastructure, Transdev has built 19 new charging stations around the city.
Transdev will train a total of 750 drivers over five weeks. As part of the training, theory is mixed with practical elements such as charging on route and in the depot, as well as driving technique. The driver training is held at the Volvo Buses Experience Center in Gothenburg. In addition to providing facilities, Volvo Buses is also responsible for training traffic instructors at Transdev.
How a driver brakes and accelerates are two things that are important for energy consumption. By braking gently, the energy generated can be returned to the battery instead of disappearing as heat. Accelerating slowly requires less energy than accelerating fast. As a driver, it is therefore extra important to plan your driving carefully and adjust your speed before traffic lights and intersections.
VOLVO 7900 ELECTRIC ARTICULATED
The Volvo 7900 Electric Articulated is 18,75 meters and can carry 150 passengers.
The buses will be charged at fast-charging stations along the route, using the industry common charging interface OppChargeTM.
At night, the buses will be charged via a CCS cable in the depot.
The bus holds six lithium-ion batteries with a capacity of 396 kWh.
The dual electric motor with two-speed transmission has a maximum power output of 2×200 kW, and maximum wheel torque at the driven axle of 31 kNm.
