The invention discloses a battery protection system and method and a vehicle. The system comprises a battery cooling device which is arranged outside a containing cavity where a battery cell is located; the liquid leakage detection device is arranged in the accommodating cavity and is in contact with the wall surface of the accommodating cavity, and an insulating material and a conductive material are arranged on the liquid leakage detection device; and the controller is connected with the battery cooling device and the liquid leakage detection device, and is used for determining the liquid leakage of the accommodating cavity based on the signal of the conductive material, and controlling the flow of the cooling liquid of the battery cooling device to be reduced to a preset flow in response to the liquid leakage of the accommodating cavity. According to the invention, the technical problem of poor protection effect on the battery cell in the accommodating cavity in the prior art is solved.
