Abstract:
1. A battery pack comprising: a plurality of cells, wherein the plurality of cells includes a first cell and a second cell connected in series; a discharge circuit electrically connected to the plurality of cells, wherein the discharge circuit comprises: an input device that: when activated, produces a battery discharge signal; a computer processor electrically connected to the discharge circuit and to the input device, the computer processor operates the first switch and the second switch in response to the battery discharge signal to simultaneously connect the first and second discharge loads in parallel to the respective first and second cells, the computer processor further receives a first voltage across the first cell and a second voltage across the second cell and compares the first and second voltages to a minimum recharge voltage, and when the first voltage and the second voltage fall below the minimum recharge voltage, the computer processor operates the first switch and the second switch to selectively disconnect the first and second discharge loads from the respective first and second cells.
