The application discloses an
energy management method for a
new energy three-
electricity system of an
engineering vehicle, and relates to the technical field of
new energy three-
electricity systems.The method comprises the following steps: S100, analyzing the driving requirements of the
engineering vehicle; S200, intelligently deciding the power; and S300, executing in real
time based on feedforward.The application constructs a three-layer closed-
loop control architecture of accurate requirement
perception, intelligent power decision and safe feedforward execution, and constructs an
energy management method with
intelligent decision capability and strong execution force.The method not only eliminates the risk of engine stalling due to the superposition of electric-
hydraulic load from the root by feedforward constraint based on real-time hydraulic power, but also realizes intelligent scheduling and fine management of battery and fuel energy by means of fixed electric quantity following and regenerative braking
recovery strategy.Meanwhile, the safety execution is ensured by battery power boundary protection and anti-integration fan mechanism, so as to comprehensively guarantee the stability and service life of the three-
electricity system.
