Systems, methods, and apparatus for providing power to storage devices

An apparatus comprising:

• a power device comprising:
• an interface to connect the power device to a storage system;
• a power source;
• and
• a power control circuit configured to:
• control, at least partially, a power transfer from the power source to a storage device;
• and
• send information about a charge state of the power device to the storage system;
• wherein at least a portion of the power device has a storage device form.

A method comprising:

• performing, at a storage structure, a power transfer with a storage device and a power device;
• and
• controlling, at least partially, by a power control circuit, the power transfer wherein the power control circuit is configured to send information about a charge state of the power device to the storage device;
• wherein the storage structure comprises:
• a power connection fabric;
• a first device interface configured to:
• receive the storage device, wherein the storage device has a form that is compatible with a device form;
• and
• connect the storage device to the power connection fabric;
• and
• a second device interface configured to receive the power device, wherein the power device has a form that is compatible with the device form;
• wherein the power control circuit is located, at least partially, at the storage device or the power device.
