The invention discloses a central liquid cooling fast charging station system. The system comprises at least one charging pile unit which is provided with a cooling liquid inlet end and a cooling liquid outlet end, a cooling liquid circulation subsystem and a cooling water circulation subsystem. The cooling liquid circulation subsystem is used for providing closed circulation of cooling liquid andcomprises a heat exchanger and a liquid feeding pump which are connected in sequence, the cooling liquid outlet ends of all the charging pile units are connected in parallel and then connected with an inlet of the heat exchanger in a butt joint manner, the cooling liquid inlet ends of all the charging pile units are connected in parallel and then connected with an outlet of the liquid feeding pump in a butt joint manner, cooling liquid is provided for each charging pile unit through the liquid feeding pump for heat dissipation and cooling, and then high-temperature cooling liquid flows back to the heat exchanger; and the cooling water circulation subsystem is used for cooling the high-temperature cooling liquid in the heat exchanger. According to the invention, one set of central liquid cooling fast charging station system is used, the liquid cooling requirements of more charging piles are met, the internal structures of the liquid cooling charging piles are simplified, the cost is reduced, the charging efficiency of the charging piles is greatly improved, and the operation stability and reliability of the charging piles are ensured.
