Thermal sensor for a battery
Thermal sensor for a battery. In an exemplary embodiment of a battery docking connector of the present disclosure, the connector comprises exposed battery contacts, and a circuit sensor electrically coupled to the exposed battery contacts for sensing the temperature at the exposed battery contacts, wherein the circuit sensor is configured to switch off an electrical load coupled thereto once a threshold temperature has been reached, to prevent overheating of a battery providing power to the electrical load.
1. A battery dock for accepting a battery and switching off an electrical load to the battery to prevent overheating, comprising:
battery contacts in alignment with battery contacts of the battery wherein the battery contacts of the battery dock and the battery contacts of the battery can be mechanically and electrically coupled in a releasable manner; and
a circuit sensor electrically coupled to the battery contacts of the battery dock, for sensing the temperature at the battery contacts of the battery dock; and
wherein the circuit sensor is configured to switch off the electrical load coupled thereto once a threshold temperature has been reached, to prevent overheating of the battery providing power to the electrical load, and wherein a charging current provided to the battery through the battery contacts of the battery dock is reduced when the temperature sensed exceeds a predetermined second threshold temperature.
2. The battery dock of claim 1 , wherein the circuit sensor comprises a thermal sensor.
3. The battery dock of claim 1 , wherein the circuit sensor comprises a thermistor.
4. The battery dock of claim 1 , wherein the circuit sensor comprises a thermocouple.
5. The battery dock of claim 1 , wherein the circuit sensor and battery contacts of the battery dock are positioned on a printed circuit board within the battery dock.
6. A method for switching off an electrical load to a battery to prevent overheating, comprising:
inserting a battery into proper alignment with a battery dock;
releasably electrically coupling battery contacts of the battery with battery contacts of the battery dock;
sensing the temperature at the battery contacts on the battery dock; and
switching off an electrical load at the battery contacts on the battery dock if the temperature sensed exceeds a predetermined threshold temperature, and further comprising the step of reducing a charging current being provided to the battery through the battery contacts of the battery dock when the temperature sensed exceeds a predetermined second threshold temperature.
7. The method of claim 6 , wherein sensing the temperature further comprises operating a circuit sensor.
8. The method of claim 7 , wherein the circuit sensor and battery contacts of the battery dock are positioned on a printed circuit board positioned within the battery dock.
9. The method of claim 6 , further comprising sending an error or alert message to a user regarding the temperature.
