Abstract

Disclosed is a wireless charging apparatus for a cable-type secondary battery. The wireless charging apparatus for the cable-type secondary battery according to the present disclosure includes a socket having a space formed inside for mounting the cable-type secondary battery, a first terminal that is electrically connected to an outer current collector of the cable-type secondary battery mounted in the socket, a second terminal that is electrically connected to an inner current collector of the cable-type secondary battery mounted in the socket, and a secondary coil for wireless charging having one end connected with the first terminal and the other end connected with the second terminal, and wound along an outer circumferential surface of the socket. According to the present disclosure, even if a secondary coil for wireless power reception is absent from a cable-type secondary battery, charging may be performed by a method for wireless power transmission and reception.

Claims

1. A wireless charging apparatus for cable-type secondary batteries, comprising:

a plate having a plurality of slits formed for mounting at least two respective ones of the cable-type secondary batteries therein, the slits each having a first end and a second end, and each of the slits having a shape corresponding to a respective one of the cable-type secondary batteries such that each cable-type secondary battery can be received within the respective slit when mounted therein;

a first terminal at a first end of the slits, the first terminal electrically connectable to an outer current collector of a first one of the cable-type secondary batteries when mounted in the first slit of the plate;

a second terminal at a second end of the slits, the second terminal electrically connectable to an inner current collector of the first cable-type secondary battery when mounted in the first slit of the plate; and

a secondary coil for wireless charging having one end connected with the first terminal and the other end connected with the second terminal.

2. The wireless charging apparatus for the cable-type secondary batteries according to claim 1, wherein the first terminal and the second terminal electrically connectable to cable-type secondary batteries mounted in the at least two slits have an electrically parallel relationship with the secondary coil for wireless charging.

3. The wireless charging apparatus for the cable-type secondary batteries according to claim 1, wherein the first terminal has a shape such that the first terminal is couplable with a first plug electrically connected to the outer current collector of the first cable-type secondary battery and formed at one end of the first cable-type secondary battery, and

the second terminal has a shape such that the second terminal is couplable with a second plug electrically connected to the inner current collector of the first cable-type secondary battery and formed at the other end of the first cable-type secondary battery.

4. A wireless charging set for cable-type secondary batteries, comprising:

a wireless charging apparatus for cable-type secondary batteries as defined in claim 1; and

a wireless charging power supply apparatus for cable-type secondary batteries including a primary coil for wireless charging.
