Abstract

The invention discloses a charging stack self-adaptive power distribution method, comprising the following steps: obtaining the maximum charging demand P of the automobile charge ; Calculate the total output power P of the idle charging module in the charging stack total ; Judgment P total Is it greater than P charge , if so, use an adaptive charging optimization algorithm to control the output power of each idle charging module. The embodiment of the present invention introduces an adaptive dynamic power allocation method, which can combine the real-time charging requirements of multiple vehicles, and flexibly and adaptively allocate the power of the charging pile, breaking through the limitations of the original traditional charger topology, and can reliably Automatic switching within the full power range solves the problem of poor adaptability of traditional chargers, and has guiding significance in practical applications.

Description

technical field [0001] The present invention relates to the technical field of power distribution of charging power sources, in particular to a charging stack adaptive power distribution method, system and equipment. Background technique [0002] With the popularization and application of electric vehicles, the specific energy and fast charging capacity of vehicle power batteries continue to improve. The capacities and charging ratios of various types of electric vehicle on-board batteries are different, and the demand for output power of chargers is also significantly different. The existing chargers are built according to fixed models, which cannot meet the diversified needs of charging, resulting in problems such as large investment, low utilization rate and poor applicability. If it is considered to configure a charger with a higher power, when charging the battery of an electric vehicle with a lower charging rate, the utilization rate of the charger module and the utili...
