Abstract

The invention discloses a method for detecting the electrolyte leakage of a battery tank and a monitoring device using the same. The method comprises the steps of: (a) respectively receiving a plurality of pairs of temperature data and pressure data from a plurality of temperature-pressure acquisition devices which are arranged at different positions in the battery tank, wherein each temperature-pressure acquisition device comprises a temperature sensor and a pressure sensor; (b) respectively fusing the received temperature data and the pressure data; (c) determining whether the fused pressure is greater than a pressure threshold under the fused temperature; and (d) determining that the battery tank has electrolyte leakage if the fused pressure is greater than the pressure threshold. According to the method for detecting the electrolyte leakage of the battery tank and a monitoring device using the same, the real-time changes of the temperature and the pressure in the battery tank can be effectively detected, so that alarm can be given in time when the battery tank has electrolyte leakage and the leakage position can be correctly obtained.

Description

technical field [0001] The present invention relates to a method and a device for detecting electrolyte leakage in a battery compartment, more specifically, to a method for detecting electrolyte leakage in a battery compartment by using a temperature sensor and a pressure sensor and a monitoring device using the method. Background technique [0002] Metal lithium-thionyl chloride battery (Li / SOCl 2 Battery) is currently the battery with the highest discharge voltage in lithium batteries, reaching 3.6V. Li / SOCl 2 When the battery is discharged at a constant current density at room temperature, the discharge curve is extremely flat. In the case of -40°C, the capacity of this battery can also be maintained at about 50% of the capacity at room temperature, so it has extremely good low-temperature operation performance. In addition, the annual self-discharge rate of this battery is about 2%, so the storage life can be as long as more than 10 years. Due to the characteristics ...
