Abstract: A fire control device comprises a box, a power wire, a pressure relieving check valve, a fire extinguishing check valve and a fire extinguisher. The box is configured to accommodate a battery system, and the power wire is configured to couple to the battery system. The pressure relieving check valve and the fire extinguishing check valve extend through the box, and a state of the pressure relieving check valve is switched between open and closed states according to a pressure difference between an inside and an outside of the box. A state of the fire extinguishing check valve is switched between open and close states according to a pressure difference between the inside and the outside of the box. The fire extinguisher is connected to the pressure relieving check valve. The fire extinguisher is switched between starting and stopping modes according to the state of the pressure relieving check valve.

Abstract: A method and a system for detecting resistance of an internal short circuit of a battery are provided. The method includes the following steps. Measuring charging/discharging information of the battery. Calculating a charging/discharging characteristic of the battery according to the charging/discharging information. Aligning the charging/discharging characteristic of the battery according to a comparison characteristic point of a comparison characteristic to obtain an aligned charging/discharging characteristic. Determining whether the battery is normal according to the aligned charging/discharging characteristic or a coulombic efficiency of the battery; and when the battery is determined as abnormal, calculating aligned charging/discharging information according to the aligned charging/discharging characteristic, and calculating the resistance of the internal short circuit of the battery according to the aligned charging/discharging information.
