BATTERY OVERHEATING PROTECTION DEVICE AND ELECTRONIC DEVICE HAVING SAME
First Claim
1. A battery overheating protection device used in an electronic device, the electronic device comprising a main unit configured to implement basic functions of the electronic device and a battery unit configured to supply power to the main unit, the battery overheating protection device comprising:
- a temperature monitoring unit configured to store a predetermined temperature value, measure a temperature value of the battery unit, and output a signal when the detected temperature value is greater than the predetermined temperature value, the temperature monitoring unit comprising at least one thermistor thermally connected to the battery unit;
a switch unit connected between the main unit and the battery unit; and
a processing unit configured to receive the signal and open the switch unit when receiving the signal, thereby the battery unit is disconnected from the main unit.

Abstract
A battery overheating protection device used in an electronic device is provided. The electronic device includes a main unit configured to implement basic functions of the electronic device and a battery unit configured to supply power to the main unit. The battery overheating protection device includes a temperature monitoring unit, a switch unit and a processing unit. The temperature monitoring unit is configured to store a predetermined temperature value, measure a temperature value of the battery unit and output a signal when the detected temperature value is greater than the predetermined temperature value. The temperature monitoring unit includes at least one thermistor thermally connected to the battery unit. The switch unit is connected between the main unit and the battery unit. The processing unit is configured to receive the signal and open the switch unit when receiving the signal, thereby the battery unit is disconnected from the main unit.
