The municipal transport company MZA in Warsaw has ordered 130 electric buses from Solaris. The Solaris Urbino 18 electric articulated buses are to be delivered to the Polish capital over the course of 2020.
According to the manufacturer, the order for 130 buses is the largest of its kind in Europe to date – it is worth around 400 million zloty, or 94 million euros. “According to our plans, we will have a fleet of almost 400 zero-emission and low-emission buses in two years’ time,” said MZA boss Jan Kuźmiński according to a press release. “MZA’s ecological buses mean hope for clean air in the capital.”
The vehicles have a 150 kWh battery, which Solaris guarantees for seven years. The vehicles are charged on the way via a pantograph or overnight in a depot. In order to be more flexible in this regard, the buses each have two charging sockets – above the right front wheel arch and behind the last door. The 400 kW fast-charging stations will be allocated in a separate procedure.

MZA has thus opted for a smaller version of the traction battery. So far, a maximum of 300 kWh is possible. The battery update, which Solaris will present in October, will increase the capacity of the storage battery to up to 550 kWh.
The vehicles ordered by the Warsaw public transport operator will be driven by two electric motors integrated into the axle. Each machine has a maximum output of 110 kW. In addition, MZA has installed a SiC voltage converter for the traction motor, which will further reduce energy consumption.
The interior of the Urbino 18 Electric is similar to that of the Solaris buses with internal combustion engines already in service in Warsaw. The cab will be closed and the bus will be equipped with air conditioning and a passenger information system. In addition, there are several USB charging sockets at which passengers can charge their smartphones, for example.
