FIELD: machine building.
SUBSTANCE: invention relates to self-propelled machine with electric transmission. Proposed machine comprises wheeled or caterpillar chassis, cabin, at least one traction motor, traction accumulator battery (ACB), electrical equipment system, power plant and / or additional ACB. Traction motor is adapted to drive at least one of its driving wheel or at least one caterpillar track. Electrical equipment system is configured to transmit electric power from traction ACB to at least one traction motor and electric heater. Power plant and / or additional ACB are capable of delivering electric energy at minimum operating temperature of self-propelled machine. System of electrical equipment is configured to control power transmission from power plant and / or additional ACB to electric heater and / or at least to one traction electric motor.
EFFECT: autonomous thermal preparation for operation of self-propelled vehicle with electric transmission is achieved with simultaneous increase of its maximum traction power.
