ABSTRACT:
An apparatus for measuring the internal pressure of a battery, including a charge/discharge unit for charging or discharging the battery, an internal pressure measuring sensor unit for measuring the internal pressure of the battery while charging or discharging the battery through the charge/discharge unit, an analog/digital converting unit for converting a sensing signal output from the internal pressure measuring sensor unit into a digital signal, a digital signal control unit for controlling the digital signal output from the A/D converting unit so that the digital signal can be applied to a computer, and the computer for recording an output signal from the digital signal control unit using a database. The apparatus can manage the data about battery's internal pressure using a data base. The apparatus also includes a gas collecting unit connected between the battery and the internal pressure measuring sensor unit and charged with argon or nitrogen gas. The gas collecting unit senses an overcharged condition of the battery as well as the internal pressure of the battery, thereby easily checking the portion of the battery (anode, cathode and electrolyte) where the gas is being generated in the overcharged condition of the battery.
