 With this flexibility comes increased complexity.  A separate energy management circuit is usually required to measure and distribute energy to the individual capacitors, which leads to increased overhead and circuit size.  The device itself must also be able to account for the current energy state of each individual peripheral or task: using the previous example, if a device wishes to transmit data it must be able to recognize whether or not the radio has sufficient power for operation and adjust its behavior accordingly. With this flexibility comes increased complexity.  A separate energy management circuit is usually required to measure and distribute energy to the individual capacitors, which leads to increased overhead and circuit size.  The device itself must also be able to account for the current energy state of each individual peripheral or task: using the previous example, if a device wishes to transmit data it must be able to recognize whether or not the radio has sufficient power for operation and adjust its behavior accordingly.

 Like federated energy, there is a price in both circuit size and complexity, requiring multiple capacitors (even when some may be rarely active) and some control circuitry and logic to switch configurations as needed: there is also some energy loss when the configuration changes, due to equalization of charges across the capacitors.  While capable of a wider range of capacitances than single or federated storage methods, the range of capacitances is ultimately limited by the number of possible combinations, so the energy profile of the device should still be well understood to ensure proper capacitor sizing. Like federated energy, there is a price in both circuit size and complexity, requiring multiple capacitors (even when some may be rarely active) and some control circuitry and logic to switch configurations as needed: there is also some energy loss when the configuration changes, due to equalization of charges across the capacitors.  While capable of a wider range of capacitances than single or federated storage methods, the range of capacitances is ultimately limited by the number of possible combinations, so the energy profile of the device should still be well understood to ensure proper capacitor sizing.
