Ride height adjustment of air suspension can be achieved by pumping air into or releasing air out of the air spring. However, energy loss would inevitably occur during the two processes, and test system of closed loop air suspension was established. Working process of the system was divided into three procedures as charging, discharging and boosting. Energy loss calculation method-compressed gas available energy was put forward, quantitative analysis of energy consumption during charging and discharging was carried out. Experiment results showed that energy consumption during charging process rises as initial air pressure of high pressure chamber increases, and during discharging and boosting processes, energy consumption decreases when initial air pressure of low pressure chamber increases. Under the same conditions, compared with open-loop air suspension, closed loop air suspension system with high & low pressure chambers can save plenty of energy.
