ELECTRIC DRIVE SYSTEM FOR AQUATIC HARVESTER POWERED BY Li-ION BATTERIES

The aquatic harvester electric vehicle for vegetation is a technical challenge for researchers due to specific requirements: high-torque operation at low travel speeds, high maneuverability, high load capacity, low draught, and affordable price. The collective of authors proposed an electro-hydraulic architecture based on paddles driven by hydraulic motors for propulsion and auxiliary services also driven by motors and hydraulic actuators. The energy source requested is the electric batteries such as a system of Li-Ion batteries connected in parallel. An electronic converter is also used to supply an electric motorthat drives a hydraulic double-circuit pump. The vehicle can be controlled remotely. The work presents the prototype made and the results of laboratory tests with it. This article's main objective isto describe the electric drive of an electric-powered aquatic harvester, underlining key features, technical solutions, novelty, and benefits ofthe proposed architecture.
