The present invention provides a cooling system for a battery pack. The cooling system for a battery pack according to the present invention comprises: a housing (1+2), an air passage, a fan (3) and at least two air holes; the housing (1+2) comprises an upper cover (1) and a box (2), the upper cover (1) is connected with the box (2); the air passage is arranged on the box and comprises an airflow cavity, an air channel and an air hole; the airflow cavity is arranged at a bottom of the box; the air channel is arranged on a side wall of the box, and the bottom of the air channel is communicated with the airflow cavity; all the air holes are arranged on the housing and communicated with the air passage, wherein at least one air hole (212) is arranged on the upper cover (1) and corresponds to a top end of the air channel; and the fan (3) is arranged inside the air passage. According to the present invention, heat dissipation in the battery pack in an environment where flowability of natural airflow is poor can be improved, such that the components in the battery pack are capable of working in a stable temperate range, and the service life of the battery pack is prolonged.
