Specifically, the first contact terminal 131 and the second contact terminal 132 may be fixed to the upper side of the fixing portion 150. Accordingly, there is a space between the first contact terminal 131 and the second contact terminal 132 and the electric conductor 120 by a distance corresponding to the distance. The fixing unit 150 can fix the resistance measuring unit 140 on the side surface of the battery cell 110, for example. The resistance measuring unit 140 is fixed on the upper portion of the fixing unit 150 and electrically connected to the first contact terminal 131 and the second contact terminal 141 via the first conductive line 141 and the second conductive line 142. [ 132, respectively.

Specifically, the first charging terminal 152 and the second charging terminal 153 of the battery 100 are connected to the first battery connection terminal 312 of the battery accommodating portion 310 implemented in the electronic device 300, 2 battery connection terminal 313, so that it is mounted in the battery receiving portion 310. The MPU connecting terminal 311 of the battery receiving part 310 and the MPU connecting terminal 151 of the battery 100 are brought into contact with each other and the MPU 320 and the resistance measuring part 140 are connected.

At this time, the MPU 320 may be connected to the resistance measuring unit 330. Specifically, the MPU 320 is connected to the resistance measuring unit 330 through the resistance measuring unit connecting terminal 321 and the resistance measuring unit terminal connecting line 322 arranged on the side surface.

Also, the resistance measuring unit 330 may be mounted in the electronic device 300, not inside the battery 100, and may be connected to the battery 100. Specifically, the resistance measuring unit 330 is connected to the resistance measuring unit connecting terminal 314 of the battery receiving unit 310 through the first battery connecting line 331 and the second battery connecting line 332. Therefore, when the resistance measurement portion connection terminal 314 and the resistance measurement portion connection terminal 154 of the battery 100 are in contact with each other, the first resistance measurement portion connection terminal connection line 331 and the second resistance measurement portion connection terminal connection The line 332 is connected to the resistance measuring unit 330 by being conducted through the first conductive line 141 and the second conductive line 142.

When the first contact terminal 131 and the second contact terminal 132 come into contact with the electric conductor 120 as the battery cell 110 is swollen and a current flows through the electric conductor 120, 330 measures a resistance value between a predetermined threshold value, for example, 20? To 40 ?.

The MPU 320 determines whether or not the battery is defective based on the received resistance value. Specifically, when the received resistance value is, for example, between 20? And 40 ?, the MPU 320 determines the state of the battery to be defective. Further, when the received resistance value is, for example, 100? Or more, the MPU 320 determines the state of the battery as normal. The state of the battery determined by the MPU 320 may be provided through the display unit 340 of the electronic device 300. [

6 is a flowchart illustrating a procedure for determining the presence or absence of a battery through a battery having a structure capable of determining whether there is a failure according to another embodiment of the present invention. For convenience of explanation, the components will be described with reference to FIG. 1 and reference numerals.

The battery 100 includes a battery cell 110, an electric conductor 120, a contact terminal 130, and a resistance measuring unit 140 as described with reference to FIG.

First, current is supplied to the two contact terminals 130 included in the battery 100, that is, the first contact terminal 131 and the second contact terminal 132 through the resistance measuring unit 140 (S610).

Specifically, the resistance measuring unit 140 supplies the generated current to the first contact terminal 131 and the second contact terminal 132 through the first conductive line 141 and the second conductive line 142.

Next, the resistance value of the electric conductor 120 configured to be attached to one surface of the battery cell 110 included in the battery 100 is measured through the resistance measuring unit 140 (S620).

At this time, the resistance value measured at the electric conductor 120 may vary depending on the contact state of the electric conductor 120 with the first contact terminal 131 and the second contact terminal 132. [ For example, when the battery cell 110 is swollen and the electric conductor 120 contacts the first contact terminal 131 and the second contact terminal 132, the current supplied from the resistance measurement unit 140 is Through the first conductive line 141 and the second conductive line 142 to the first contact terminal 131, the second contact terminal 132 and the electric conductor 120. Accordingly, the resistance measuring unit 140 measures the resistance value of the electric conductor 120 of 40 or less as the electric current is conducted.

Further, for example, when the battery cell 110 does not swell, the electric conductor 120 and the first contact terminal 131 and the second contact terminal 132 do not contact each other. Therefore, the current supplied from the resistance measuring unit 140 stays only at the contact terminal 130, and the resistance measuring unit 140 measures the resistance value of the electric conductor 120 of 100? Or more.

Then, it is determined whether the battery 100 is defective based on the resistance value through the MPU 320 included in the electronic device 300 (S630).

Specifically, the MPU 320 receives the resistance value measured by the resistance measuring unit 140, and determines whether the battery 100 is defective based on the received resistance value. For example, when the resistance value is 40 Ω or less, the MPU 320 determines that the battery cell 110 is swollen and determines that the state of the battery 100 is defective. When the resistance value is equal to or greater than 100?, The MPU 320 determines that the swelling degree of the battery cell 110 is normal, and determines that the state of the battery 100 is normal. At this time, whether or not the determined battery 100 is defective can be provided through the display unit 340 of the electronic device 300. The specific embodiment of providing the presence or absence of defects of the battery 100 will be described later with reference to FIGS. 7A and 7B.

Although the battery 100 is shown as including the resistance measuring unit 140 for convenience of explanation, the resistance measuring unit may be included in the electronic device 300 and may be included in the battery 100, The resistance value of the conductor 120 can be measured in the electronic device 300.

Accordingly, the battery 100 has a structure capable of measuring the resistance value of the electric conductor 120 through the resistance measuring unit 140, so that the user can operate the MPU 320 as a control unit of the electronic device 300 The presence or absence of a faulty battery can be provided based on the resistance value.

FIGS. 7A and 7B illustrate a failure status notification screen of a battery having a structure capable of determining whether there is a failure according to another embodiment of the present invention.

Referring to FIG. 7A, the display unit 340 of the electronic device 300 equipped with the battery 100 provides a screen of an application that guides the status of a normal battery. Specifically, the display unit 340 provides information on the status of the mounted battery, the current battery remaining amount, the battery manufacturing date, and the number of times the battery is charged. For example, the display unit 340 displays 'the state of the battery is normal.' , A normal determined battery state, a 67% current battery remaining amount, a battery manufacture date of August 05, 2016, and a battery charge count of 150 times. At this time, the number of battery charging times can be measured and provided by a PCM (Protection Circuit Module) included in the electronic device 300.

Referring to FIG. 7B, the display unit 340 of the electronic device 300 equipped with the battery 100 provides a screen of an application for guiding the status of a defective battery. For example, the display unit 340 displays 'Replace battery.' , The battery status determined to be defective, the current remaining battery level of 50%, the date of manufacture of the battery on August 05, 2016, and the number of times the battery is charged, which is 150 times.

Accordingly, the electronic device 300 provides an indication of whether the battery is defective through an application, thereby allowing the user to more easily recognize the state of the battery which is difficult for the user to directly judge.
