Potential energy regeneration device for electric forklift

Abstract

The invention discloses a potential energy regeneration device for an electric forklift. The potential energy regeneration device comprises a motor load system, a voltage reduction type conversion circuit, a master control module, a constant current control module and a power module. The constant current control module and the power module are electrically connected. The motor load system, the voltage reduction type conversion circuit and the power module are electrically connected with the master control module and controlled by the master control module. The potential energy regeneration device for the electric forklift is provided, accordingly, load falling heating is greatly reduced, and energy regeneration and utilization are achieved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an energy-saving device for electric forklifts based on storage batteries and supercapacitors. Background technique [0002] In recent years, the scale of my country's logistics industry has continued to grow rapidly. In 2015, the total amount of social logistics in the country reached 219.2 trillion yuan, an increase of 3.68 times compared with 2006, with an average annual growth rate of 15.58%. The total cost of social logistics accounted for 16% of the national GDP. Among them, forklifts are the core handling equipment in the logistics industry. China's forklift industry has grown at an average annual rate of 30% for more than ten consecutive years, and has become the world's largest forklift production base. However, global warming and energy issues are becoming increasingly prominent, and high fuel prices have prompted the forklift industry to solve the current problem of la...
