Abstract

Abstract:

In order to improve the efficiency of electric engineering vehicles,a non power point energy storage power supply is proposed.The various working modes,charging and recharging processes of non power supply energy storage power supply is analyzed in detail.The testing analysis and verification are conducted.The results show that the proposed device can achieve continuous operation of electric engineering vehicles in construction sites without power sources,and can also serve as an emergency power source to provide emergency electrical energy support for production and daily life on the construction site.

Key words: electric engineering vehicle, non power point, energy storage power supply, emergency power supply
