PURPOSE: An apparatus and method for charging a battery having a positive terminal, a negative terminal, and a third terminal is provided to permit simultaneous monitoring of battery temperature by a charger. CONSTITUTION: An apparatus for charging a battery includes a positive contact positioned soas to engage the positive terminal of the battery, a negative contact positioned so as to engage the negative terminal of the battery, a third contact positioned so as to engage the third terminal of the battery, and a logic circuit connected to the positive, negative and third terminals. In addition, a switching device is provided which receives an input from the logic circuit that dictates whether the switching device is positioned closed so as to connect the third contact to a biasing source. The position of the switching device is determined by comparing the voltage at the third contact to a predetermined threshold voltage. |
