Abstract

Discussed is a battery property measurement apparatus including a main body made of an insulative material, the main body being configured to be put on a hand of a user; and a measurement unit installed at a portion of the main body at which a finger of the user is located, the measurement unit being configured to contact at least a portion of respective opposite ends of a battery, the measurement unit being electrically connected to the battery when the user push on the battery using the finger in a state in which the battery is coupled to the measurement unit.

First claim

The invention claimed is:

1. A battery property measurement apparatus comprising:
a main body made of an insulative material, the main body being configured to be put on a hand of a user; and
a measurement unit installed at a portion of the main body at which a finger of the user is located, the measurement unit being configured to contact at least a portion of respective opposite ends of a battery, the measurement unit being electrically connected to the battery when the user push on the battery using the finger in a state in which the battery is coupled to the measurement unit,
wherein the measurement unit comprises:
a positioning member comprising a base portion coupled to the main body, a gripping portion, and an installation space forming a through hole extending from the base portion to the gripping portion, wherein the base portion is formed so as to have a shape capable of wrapping a portion of the finger, and the gripping portion is configured to contact a portion of one end of the battery;
a conductive member installed in the installation space defined in the positioning member, the conductive member being made of a conductive material, the conductive member being configured to be moved in the installation space in a direction away or toward the finger by an external force, and the conductive member having a first end located at the base portion and a second end located at the gripping portion; and
an elastic member installed in the installation space, the elastic member being configured to elastically support the conductive member, the elastic member applying an elastic force such that the conductive member is maintained in a state of being located adjacent to the finger when the external force applied to the conductive member is removed,
wherein the first end of the conductive member sticks out of the installation space at the base portion when the external force applied to the conductive member is removed.

2. The battery property measurement apparatus according to claim 1 , wherein the gripping portion of the positioning member comprises:
a fixing portion fixed and coupled to the base portion; and
a detachment portion detachably coupled to the fixing portion, the detachment portion being configured to contact the portion of one end of the battery.

3. The battery property measurement apparatus according to claim 2 , wherein the detachment portion has a ring shape.

4. The battery property measurement apparatus according to claim 2 , wherein an inner diameter of an inner surface of the gripping portion gradually decreases from a tip end thereof to the conductive member.

5. The battery property measurement apparatus according to claim 1 , wherein the elastic member is a compression spring.

6. The battery property measurement apparatus according to claim 1 , wherein an inner diameter of an inner surface of the gripping portion gradually decreases from a tip end thereof to the conductive member.

7. The battery property measurement apparatus according to claim 1 , further comprising an insulative member made of a material that is insulative and elastically deformable, the insulative member being installed in the main body, and the insulative member being installed so as to wrap a portion of the conductive member that contacts the finger.

8. The battery property measurement apparatus according to claim 1 , comprising:
a coupling member coupled to the main body, an external device being detachably coupled to the coupling member; and
a connection member made of a conductive material, the connection member being installed at the main body, and the connection member being configured to electrically connect the measurement unit and the coupling member to each other.

9. The battery property measurement apparatus according to claim 8 , wherein the connection member is made of a conductive fiber.

10. The battery property measurement apparatus according to claim 8 , wherein the external device is configured to measure one or more of voltage, current, and internal resistance of the battery.

11. The battery property measurement apparatus according to claim 1 , wherein the measurement unit includes a first measurement unit to contact a first end of the opposite ends of the battery, and a second measurement unit to contact a second end of the opposite ends of the battery.

12. The battery property measurement apparatus according to claim 11 , wherein the first measurement unit is installed on one of an index finger or a middle finger of the user, and the second measurement unit is installed on a thumb of the user.

13. The battery property measurement apparatus according to claim 1 , wherein the second end of the conductive member sticks out of the installation space at the gripping portion when the external force is applied to the conductive member.
