| titleOfInvention | Battery pack with temperature activated boost circuit |
| abstract | A battery pack (100) having at least one electrochemical cell (103) and a temperature dependent boost circuit (104) is provided. Since the cell voltage is diminished at low temperatures, and as portable electronic devices typically have a minimum operational voltage limit, the boost circuit (104) is actuated at low temperatures to step up the voltage from the cell (103) to the electronic device. In one embodiment, the boost circuit (104) is coupled serially between the cell (103) and the output terminals of the battery pack (100). In parallel with the boost circuit (104) is a boost bypass circuit (105). A controller (106) senses the temperature of the battery pack (100) from a temperature sensor (110), like a thermistor. When the temperature falls below a predetermined minimum temperature threshold, the controller (106) actuates the boost circuit (104), thereby increasing the output voltage of the pack (100). Concurrently with the actuation of the boost circuit (104), the controller (106) causes the boost bypass circuit (105) to enter a high impedance state. |
