Disclosed is a hybrid electrochemical cell having two (or more) sub-cells each with different cell chemistry. For example, a second electrochemical sub-cell has a metal fuel electrode with the same type of metal fuel in a first electrochemical sub-cell, but has a different battery chemistry than the first sub-cell. A controller is configured to selectively generate an electrical current from at least one sub-cell in a discharge mode and selectively apply an electrical current to at least one sub cell in a charge mode, e.g., by controlling an open or closed state of switches. The operating modes may be controlled based on input parameters.

Hybrid electrochemical cell systems and methods of operation

A system includes a boost converter configured to amplify input voltage received from one or more power sources into output voltage. The system also includes a current sensor configured to sense a current of the input voltage for example, by induction. The system further includes a controller configured to adjust an amplification of the boost converter in response to the current sensed by the current sensor. When utilized in each of a plurality of power source modules coupled to a common load, the power source modules adjust the amplifications of their boost converters towards equalization of their output voltages and their currents in response to sensed currents of the input voltages changing through demand of the common load. Associated systems and methods are also disclosed.
