The invention discloses a power battery pack and an electric automobile with the same. The disclosed power battery pack comprises at least two parallel battery modules (1), a case (2) and a forced air-cooling device (3), wherein the case (2) is used for accommodating the battery modules (1), the forced air-cooling device (3) acts on the case (2) and the battery modules (1), the case (2) is provided with a ventilation hole (4), and cooling air flows between the forced air-cooling device (3) and the ventilation hole (4). The forced air-cooling device (3) can quicken the flow of the cooling air in the power battery pack, disperses heat generated in batteries from a channel as soon as possible, effectively increases the heat dispersion performance of the battery modules, ensures the temperature of the batteries not to be over high, improves the work environment of the batteries and prolongs the service life of the power battery pack.
