Electric bus LIAZ 6274 with lithium-ion accumulators - joint development of "Russian Buses - GAZ Group" and "MOBEL" companies.
Application of innovative technologies and high technological level of used components allowed to create non-polluting and economic electric bus which meets the modern requirements shown to public city transport.
Components of electric bus
Three-phase, asynchronous, 180 kW
Power IGBT-converter with energy recuperation function
Liotech's lithium-ion accumulators
Three-phase, 380 V, 90 kW
The combined system of electrodynamics braking with the traction engine and pneumatic drive with division into contours on axes
Bipolar, remote, with additional entrance of control from external sensors in case of emergency
Isolation control device
Signals about normal state of isolation, norm decrease and an accident condition. In the last case, gives out a signal of the main switch shutdown. The mode of device's self-diagnostic is provided
Liquid, with a diesel heater. In addition, carries out thermostat function for energy storages.
