Battery module capable of suppressing spread of battery fire and control method of suppressing spread of battery fire the same

A control method of suppressing spread of battery fire, applied to a battery module comprising a case, and the battery module further comprises a plurality of battery packs connected in series or in parallel, a plurality of temperature sensors dispersedly configured to an accommodation space of the case, an energy consumption module, and the control method comprising:

• determining whether an ambient temperature detected by one of the temperature sensors is greater than or equal to a first specific temperature range, and
• activating the energy consumption module to enter an energy consumption mode when the ambient temperature detected by the one of the temperature sensors is greater than or equal to the first specific temperature range, and the energy consumption mode comprises steps of:
• (a) controlling the energy consumption module to consume the battery capacity of at least one battery pack around one of the temperature sensors,
• (b) determining whether a parameter corresponding to the at least one battery pack satisfy a specific condition, and
• (c) controlling the energy consumption module to stop consuming the battery capacity of the at least one battery pack to exit the energy consumption mode when the parameter satisfies the specific condition,
• wherein the parameter is set to be the ambient temperature, the specific condition is set to be a second specific temperature range, and the energy consumption mode further comprises:
• (b1-1) determining whether the temperature difference of the ambient temperature detected by the one of the temperature sensors and an ambient temperature detected by one of remaining of the temperature sensors is less than or equal to a second temperature difference threshold when the second specific temperature range is the second temperature difference threshold, and
• (b1-2) determining the parameter satisfy the specific condition when the temperature difference is less than or equal to the second temperature difference threshold, or
• (b2-1) determining whether the ambient temperature detected by the one of the temperature sensors is less than or equal to a second temperature threshold when the second specific temperature range is the second temperature threshold, and
• (b2-2) determining the parameter satisfy the specific condition when the ambient temperature is less than or equal to the second temperature threshold, or
• (b3-1) determining whether the ambient temperature detected by the one of the temperature sensors is greater than or equal to a third temperature threshold when the second specific temperature range is the third temperature threshold, and
• (b3-2) determining the parameter satisfy the specific condition when the ambient temperature is greater than or equal to the third temperature threshold.
