A hydraulic system may include an electric motor and a power source electrically coupled to the electric motor. During operation of the hydraulic system in an energy recovery mode, a net negative torque may be applied to the electric motor causing the electric motor to convert a mechanical power output to an electrical input and provide the electrical input to the power source. The hydraulic system may include a controller configured to determine a time that the hydraulic system operates in the energy recovery mode and cause, during the time that the hydraulic system operates in the energy recovery mode, application of an energy recovery prevention torque to the hydraulic system. The energy recovery prevention torque may prevent the electric motor from converting the mechanical power output to the electrical input and providing the electrical input to the power source.
