1. An accumulator for storing fluid, comprising:
a shell that defines an interior volume;
an accumulator shaft extending at least partially across the interior volume from a first interior surface of the shell;
a piston-plate disposed in the interior volume such that the piston-plate and a second interior surface of the shell define a chamber in the interior volume, the chamber configured to be in fluid communication with a fluid system during operation of the piston-plate; and
a motor coupled to the piston-plate,
wherein an interface between the shell and at least one of the motor or piston-plate is a threaded interface and allows the piston-plate to linearly travel along the shell.
