1. Introduction. The vehicle steering system is a bridge and link connecting the human-vehicle-road closed-loop system. Its performance not only affects the handling feeling [1], [2] but also is an important part of the vehicle energy flow [3].With the increasing requirements for energy conservation, environmental protection and safety, the energy …
Pumped Storage Hydropower
In this paper, a novel series hybrid hydraulic excavator based on electro-hydraulic composite energy storage, which provides the average power of the system through the diesel engine, and the battery
Hydraulic accumulators must be pre-charged with an inert gas, typically nitrogen (Class 4.0, filtration < 3μm). Compressed air or oxygen should never be used due to risk of explosion. For energy storage applications, the pre-charge pressure must be less than or equal to 90 per cent of the minimum operating pressure of the hydraulic system.
2. Considering the optimization strategy for charging and discharging of energy storage charging piles in a residential community. In the charging and discharging process of the charging piles in the community, due to the inability to precisely control the charging time periods for users and charging piles, this paper divides a day into 48 time …
