The invention relates to the technical field of heat dissipation systems, in particular to a battery heat dissipation system of a new energy automobile and a control method of the battery heat dissipation system. The invention aims to solve the problem of poor heat dissipation effect of the battery of the new energy automobile. In order to achieve the purpose, the battery cooling system comprises a compressor, an outdoor heat exchanger, a throttling element, an indoor heat exchanger and a cooling heat exchanger, an exhaust port of the compressor communicates with an inlet of the outdoor heat exchanger, and an outlet of the outdoor heat exchanger communicates with an inlet of the throttling element; an outlet of the throttling element communicates with an inlet of the indoor heat exchanger and an inlet of the cooling heat exchanger simultaneously, an outlet of the indoor heat exchanger and an outlet of the cooling heat exchanger communicate with an air suction port of the compressor simultaneously, and the cooling heat exchanger is arranged at a battery of the new energy automobile so as to conduct heat exchange with the battery. The cooling heat exchanger and the battery can be used for heat exchange so as to dissipate heat of the battery.
