Abstract

The invention discloses an all-electric aerial work platform energy recovery control system and method. The system comprises a battery pack, an energy recovery control circuit, a control electricity module, a lifting electric transmission assembly motor controller, a man-machine interaction module, a whole machine control module, a lifting electric transmission assembly, a platform and a lifting mechanism. The energy recovery control circuit is additionally arranged in a system loop, the energy recovery control circuit is used for switching the working modes of the battery pack on the premise that the lifting performance of the whole machine working platform is not affected, the potential energy of the platform is effectively recovered by the battery pack at different temperatures and SoC, and therefore, coupling control over platform lifting and energy recovery is achieved. Compared with an existing energy recovery device provided for a hydraulic drive type AWP, the energy recovery efficiency of the full-electric AWP can be improved, and the electric energy utilization rate of the whole machine is increased; and the installed capacity of the whole battery pack of the AWP can be optimized, and the purpose of reducing the manufacturing cost of the whole battery pack is achieved.

Description

technical field [0001] The invention belongs to the technical field of aerial work platforms, and in particular relates to an energy recovery control system and method for an all-electric aerial work platform. Background technique [0002] Aerial Work Platform (AWP) is widely used in modern production and life because of its low working space requirements, flexible movement, and convenient transportation. It has become an essential working tool in hotels, electronics factories, warehouses and other areas. In recent years, with the development of electrified transmission assembly, people have put forward higher requirements for AWP in terms of zero emission and no hydraulic oil leakage, which makes the full electric development of AWP an inevitable trend. Thanks to the all-electric AWP, the whole machine system adopts an all-electric drive mechanism, which provides inherent conditions for the potential energy recovery of its lifting mechanism. Therefore, it is very important...
