The invention discloses an intake silencer system for an air compressor pump and an extended-range electric vehicle adopting the intake silencer system. The intake silencer system comprises an air filter, a turbocharger, an intercooler, an engine, the air compressor pump and an air storage tank. The air filter, the turbocharger, the intercooler and the engine are connected in sequence to form a first airflow channel. Air sequentially passes through the air filter, the turbocharger and the intercooler and reaches the engine. The air filter, the turbocharger, the intercooler, the air compressor pump and the air storage tank are connected in sequence to form a second airflow channel. The air sequentially passes through the air filter, the turbocharger, the intercooler and the air compressor pump and reaches the air storage tank. The intake silencer system and the extended-range electric vehicle have the beneficial effects as follows: an excellent silencing effect on the air compressor pump is achieved, the number of system components is reduced, the structure is simple, and the manufacturing cost and the maintaining cost are reduced; waste gas energy of the engine is sufficiently used, the efficiency of the air compressor pump is improved, and the energy consumption of a finished automobile is reduced; and the working intensity of the air compressor pump is reduced, the service life is prolonged, and the maintenance interval is prolonged.
