Artemis Intelligent Power demostrates hydraulic hybrid BMW 530i w/Video
Like an electric hybrid, under braking, the drive motors are used to pressurize the accumulator. The company claims this is a more cost-effective solution than batteries. While the system can capture kinetic energy quickly - like an ultracapacitor - the energy storage capacity of the accumulators is unfortunately limited, making this configuration less useful for cars, particularly in highway driving. The series hydraulic hybrid is best suited to urban-use trucks like delivery vans or buses where there is more room for the accumulators. Artemis claims a 50 percent reduction in urban fuel consumption on its demonstrator vehicle. The key difference that Artemis is claiming for its version is the design of the hydraulic pump motor which is claimed to provide greater efficiency and more precise control.
