for each battery cluster among the other battery clusters except the first target battery cluster, obtain a probability of thermal runaway of said each battery cluster in a next period based on temperature data of said each battery cluster in a current period and temperature data of said each battery cluster in a historical period;
obtain a confidence score for an isolation-and-suppression device in said each battery cluster supporting the first target battery cluster, according to the probability of thermal runaway of said each battery cluster in the next period, and a pipeline length between the isolation-and-suppression device in said each battery cluster and a spraying device for the inhibitor in the first target battery cluster; and
determine a battery cluster in which an inhibitor is in the normal state and which has a lowest confidence score among the other battery clusters except the first target battery cluster, as the second target battery cluster;
wherein in terms of obtaining the probability of thermal runaway of said each battery cluster in the next period based on the temperature data of said each battery cluster in the current period and the temperature data of said each battery cluster in the historical period, the control host is configured to:
predict temperature data of said each battery cluster in the next period by using the temperature data of said each battery cluster in the current period and the temperature data of said each battery cluster in the historical period; and
