Abstract
The invention is directed to battery power management. In one embodiment, the invention provides a battery control unit for managing battery power supplied to a product, the battery control unit including: a first battery and a second battery coupled to each other in a parallel configuration, each of the first and second batteries having a negative terminal coupled to an electrical ground of the product; a first switch having a first terminal coupled to a positive terminal of the first battery and a second terminal coupled to a power terminal of the product; a second switch having a third terminal coupled to a positive terminal of the second battery and a fourth terminal coupled to the power terminal; a first voltage sense unit coupled to the positive terminal of the first battery for sensing a voltage at the positive terminal of the first battery; a second voltage sense unit coupled to the positive terminal of the second battery for sensing a voltage at the positive terminal of the second battery; a first control unit coupled to the first switch for controlling the first switch in response to the voltage sensed by the first voltage sense unit; and a second control unit coupled to the second switch for controlling the second switch in response to the voltage sensed by the second voltage sense unit.
