The invention discloses a direct-current double-gun fast charging system of a new energy automobile. The direct-current double-gun fast charging system comprises a battery pack, a main direct-current fast charging structure and an auxiliary direct-current fast charging structure. The main direct-current fast charging structure is arranged on the vehicle body and electrically connected with the first charging gun, the positive electrode of the main direct-current fast charging structure is electrically connected with the positive electrode output bus of the battery pack, and the negative electrode of the main direct-current fast charging structure is electrically connected with the negative electrode output bus of the battery pack. The auxiliary direct-current fast charging structure is arranged on the vehicle body and electrically connected with the second charging gun, the positive electrode of the auxiliary direct-current fast charging structure is electrically connected with the positive electrode output bus of the battery pack, and the negative electrode of the auxiliary direct-current fast charging structure is electrically connected with the negative electrode output bus of the battery pack. The first charging gun and the second charging gun perform charging output control through the corresponding charging piles. According to the technical scheme, the vehicle charging time can be greatly shortened, and the long-distance travel requirement of people is met. Moreover, the direct-current double-gun fast charging system provided by the invention is good in stability, safe and reliable, and can certainly generate far-reaching influence in the future.
