Abstract
A battery pack including a first subset of battery cells and a second subset of battery cells, set of switches, a DC output port and an AC output port. The battery pack may provide both a DC output signal at the DC output port and an AC output signal at the AC output port by selectively activating the switches of the set of switches. The battery pack may couple the first subset of battery cells and the second subset of battery cells in a parallel configuration or a series configuration.
Claims17
A battery pack, comprising:
- a set of battery cells including a first subset of battery cells and a second subset of battery cells;
- a DC output port, the first subset of battery cells and the second subset of battery cells are coupled in series and to the DC output port to provide a DC output signal;
- an AC output port;
- and
- a set of switches, the set of switches may be controlled and configured such that the first subset of battery cells and the second subset of battery cells may be alternatively coupled to the AC output port to provide an AC output signal.

A battery pack, comprising:
- a set of battery cells including a first subset of battery cells and a second subset of battery cells;
- a DC output port;
- an AC output port;
- and
- a converter switch, the converter switch may be controlled and configured such that in a first configuration the first subset of battery cells and the second subset of battery cells are coupled in parallel and to the DC output port to provide a DC output signal and in a second configuration the first subset of battery cells and the second subset of battery cells are coupled in series and to the AC output port to provide an AC output signal.
