Electric bus LIAZ-6274

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

Engine 

Three-phase, asynchronous, 180 kW

Traction inverter 

Power IGBT-converter with energy recuperation function

Energy stores 

Liotech's lithium-ion accumulators

Charger

Three-phase, 380 V, 90 kW

Braking system

The combined system of electrodynamics braking with the traction engine and pneumatic drive with division into contours on axes

Main switch 

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

Heating system 

Liquid, with a diesel heater. In addition, carries out thermostat function for energy storages.
