What are HHVs?

The Environmental Protection Agency has paired up with engineers to create an innovative and extremely efficient method to powering automobiles. After a lot of time and money, they have come up with and released the Hydraulic Hybrid Vehicle. The Hydraulic Hybrid Vehicle, better known as an HHV, is an enormous advancement in automotive technology that is creeping its way into everyday life. These vehicles are driven by two different powers sources, a regular internal combustion engine and a hydraulic motor. The hydraulic hybrid system is made up of hydraulic fluid vessels called accumulators and hydraulic drive pumps. The hydraulic drive acts as a motor to power the wheels. The hydraulic drive also acts like a pump to re-pressurize the accumulators using the momentum of the vehicle. Braking in the vehicle converts kinetic energy into potential energy and it is called regenerative braking.   This system is available in 2 types: series and parallel.
