The embodiment of the invention provides a battery cooling liquid leakage detection method and device and related devices, and belongs to a battery management technology. The invention just aims to solve the technical problem that the leakage of cooling liquid cannot be detected timely and comprehensively in the prior art is solved. The battery cooling liquid leakage detection method comprises the following steps that: performance parameters of a battery in real time is detected through a monitoring unit arranged in a battery pack; the liquid level of cooling liquid in an external cooling kettle is detected in real time through a liquid level sensor, wherein the cooling kettle is arranged in an external cooling liquid system for cooling the battery; according to the liquid level, detected in real time, of the cooling liquid, the variable quantity of the liquid level of the cooling liquid in the cooling kettle is calculated; whether the cooling liquid of the battery leaks or not is judged according to the perf
