Claim 10:
11. A linkage control method for the battery clusters, applied to the linkage control system for the battery clusters of claim 1, comprising:
receiving periodically the environmental data sent by the plurality of detector modules and corresponding to the battery clusters, wherein the plurality of detector modules respectively correspond to the battery clusters;
determining, by the control host, the first target battery cluster in which thermal runaway occurs according to the environmental data, and determining whether the inhibitor in the isolation-and-suppression device A in the first target battery cluster is in the normal state;
determining, by the control host, the second target battery cluster in which the inhibitor is in the normal state from the other battery clusters except the first target battery cluster, when the inhibitor in the isolation-and-suppression device A is in the abnormal state; and
switching on, by the control host, the solenoid valve of the isolation-and-suppression device B in the second target battery cluster, to let the inhibitor in the isolation-and-suppression device B be conveyed to the first target battery cluster through the pipeline to solve thermal runaway;
wherein the environmental data comprises the temperature data, and determining the second target battery cluster in which the inhibitor is in the normal state from the other battery clusters except the first target battery cluster comprises:
for each battery cluster among the other battery clusters except the first target battery cluster, 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;
obtaining the confidence score for the 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 the pipeline length between the isolation-and-suppression device in said each battery cluster and the spraying device for the inhibitor in the first target battery cluster; and
determining the battery cluster in which the inhibitor is in the normal state and which has the lowest confidence score among the other battery clusters except the first target battery cluster, as the second target battery cluster;
wherein 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 comprises:
predicting the 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
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 next period and the first preset temperature value, wherein the first preset temperature value is the battery self-heating temperature T1.
