Abstract

Various embodiments of a battery pack, a mobile terminal having such a battery pack, and related methods are disclosed. In one exemplary embodiment, a battery pack for a mobile terminal may include a battery cell, a temperature sensor configured to measure a temperature of the battery cell, a charge detector configured to detect whether the battery cell is charged above a predetermined level, and a first connector terminal configured to electrically connect to the mobile terminal.

Claims

1. A mobile terminal comprising:

a battery pack where an L-shaped first connecter terminal is formed;

a cover including an electrical power coil receiving an electrical power signal, where a fourth connector terminal is formed; and

a terminal body including a second connecter terminal, a third connector terminal, and a rectification module configured to rectify an alternative power generated from the electrical power coil,

wherein one side of the L-shaped first connecter terminal is connected to the second connecter terminal and the third connector terminal, and the other side of the L-shaped first connecter terminal is connected to the fourth connector terminal of the cover.

2. The mobile terminal of claim 1,

wherein the cover substantially encloses at least the battery pack;

and

the second connector terminal configured to transmit the wireless electrical power signal from the electrical power coil to the battery pack.

3. The mobile terminal of claim 1, wherein the fourth connector terminal comprises a plate spring.

4. The mobile terminal of claim 1, wherein a reception power control block and a charge control block are disposed between the second connector terminal and a third connector terminal.

5. The mobile terminal of claim 2, wherein the second connector terminal is electrically connected to the first connector terminal.
