3. The accumulator system of claim 1 , wherein the balance chamber is configured to receive a second fluid as the piston moves in a first direction and to discharge the second fluid as the piston moves in a second direction opposite the first direction.

4. The accumulator system of claim 1 , wherein, the electric actuator includes an electric motor including a rotor and a stator, each of the rotor and the stator being disposed in the balance chamber.

5. An accumulator system, comprising:

an accumulator system housing, the accumulator system housing defining a function chamber and a balance chamber;

a piston configured to move axially within the accumulator system housing, the piston configured to separate the function chamber from the balance chamber;

a plurality of roller screws configured to couple directly to the shaft and to the screw adapter, wherein the roller screws are configured to transfer rotation of the screw adapter to axially move the shaft;

an anti-rotation housing defining a cavity and at least one slit; and

at least one anti-rotation guide,

wherein the shaft is received in the cavity of the anti-rotation housing, and

wherein the at least one anti-rotation guide extends into the at least one slit to block rotation of the shaft by contacting the anti-rotation housing.

6. The accumulator system of claim 5 , wherein the electric actuator is within the balance chamber.

7. The accumulator system of claim 5 , wherein the balance chamber is configured to receive a second fluid as the piston moves in a first direction and to discharge the second fluid as the piston moves in a second direction opposite the first direction.
