Solaris Urbino electric LE 8.9 is a low-entry city bus manufactured by Solaris Bus & Coach from Bolechowo near Poznań in Poland. It was presented for the first time in the autumn of 2011. Series production began in 2013.[1]

History[edit]

On 20 September 2011, during the Transexpo Trade Fair in 2011, the company presented the first prototype of the Solaris Urbino electric LE 8.9.[2] The new model is equipped with an electric drive engine power system, whose main component is produced by the German company Vossloh Kiepe, a four pole asynchronous motor with a maximum power of 120 kW (163 HP) and maximum torque of 1400 Nm. The energy to power the motor is stored in two liquid-cooled lithium batteries with a total capacity of 120.9 kWh and a rated voltage of 600V, which is made by Wamtechnik in Poland.[3] The maximum charging time for two batteries with a total weight of 1400 kg at a 63A 3x400V loading terminal is 4 hours and can be accessed via a plug-in connector by Walter company. Regenerative braking is used to extend battery life by recovering energy from momentum back into the battery when slowing[4] The maximum range of 100 km, and the bus is able to reach a top speed which is limited to 50 km/h. The brake coil reduces the rate of acceleration of the bus. Electric batteries have been used to replace compressors driven by an internal combustion engine, so in addition to the drive system there is an energy source for all other systems on the bus, including power steering, heating, ventilation and the electrically control doors. Electrical system is based on CAN bus.[5]
