4 FAQs about New Energy Pure Electric Energy Storage Excavator

What is a new energy regeneration system for hydraulic excavators?

Based on these insights, a novel energy regeneration system for the swing drive of the hydraulic excavators is proposed. This system integrates an automatic switch control system, designed to optimize energy savings and enhance regeneration efficiency, along with an intelligent brake control system for precise tracking of the swivel angle.

How to improve excavator energy eficiency?

In order to improve excavator energy eficiency, an electric excavator scheme using a hydraulic-electric dual-power drive boom system is proposed. A linear actuator, including electro-mechanical unit and hydraulic unit, was adopted in the boom system.

Can hydraulic accumulator and supercapacitor recover gravitational potential energy?

Chen et al. studied a variable speed pump control boom system in which hydraulic accumulator and supercapacitor are used to recover gravitational potential energy. The energy consumption of the system is reduced by 33.1% . Yoon et al. proposed an electric excavator system that each hydraulic actuator is driven by a closed pump control system.

What is the energy eficiency of excavator multi-way valve control system?

According to related literatures, the energy eficiency of the excavator multi-way valve control system is only 30%. The shortage of low energy eficiency leads to high installed power, high cost and short endurance of excavator batteries, which seriously restricts the promotion and application of electric technology in excavators.
