Abstract

The invention relates to an energy supply control method and system. The method comprises the steps that energy supply working condition data is acquired, divided and processed to obtain battery statechange data; state transfer path data is acquired, and battery state change data and state transfer path data are processed to obtain a path control variable; the path control variable is processed to obtain stage energy consumption data; according to the stage energy consumption data, the lowest total energy consumption is acquired to obtain optimized control data. According to the energy supplycontrol method and system, the technical problem is solved that the energy saving effect in the prior art is poor.

Description

technical field [0001] The invention relates to a hybrid power control technology, in particular to an energy supply control method and system. Background technique [0002] A hybrid vehicle has at least two power sources, generally one of which is an internal combustion engine, and the other is a battery. To improve the economics of HEVs, various energy management strategies have emerged. The energy management strategy and online optimization method in the prior art cannot obtain the global optimal solution, and cannot fully utilize the energy-saving potential of hybrid electric vehicles, so that the best vehicle economy cannot be obtained, and the influence of motor power loss is not considered, so The selected engine operating point cannot guarantee the lowest comprehensive energy consumption of the power system. [0003] To sum up, there is a technical problem of poor energy saving effect in the prior art. Contents of the invention [0004] In view of the technical ...
