Abstract

The invention discloses a testing method of an energy storage battery for a charging pile. The method comprises the steps of determining an electric discharging parameter for performing electric discharging testing on the energy storage battery; performing electric discharging testing on the energy storage battery according to the electric discharging parameter; acquiring an electric discharge curve of the energy storage battery in the electric discharging testing process; searching a template curve which matches an electric discharging curve of the energy storage battery in the electric discharging testing process, and determining the operation state of the energy storage battery according to the matched template curve. The testing method settles a technical problem of relatively long time consumption for performing electric discharging testing on the energy storage battery in prior art. According to the method of the invention, a resistance factor beta is used as a determining standard for attenuation degree; because the resistance factor beta is a parameter which is unrelated with temperature, the testing method of the invention can effectively reduce measurement errors of voltage, current and temperature.

Description

[0001] Technical field [0002] The invention relates to the field of charging piles, in particular to a method for testing energy storage batteries used in charging piles. Background technique [0003] With the deepening of the global energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, energy saving and emission reduction are the main directions of future automotive technology development. As a new generation of transportation, electric vehicles have incomparable advantages over traditional vehicles in terms of energy saving, emission reduction and reducing human dependence on traditional fossil energy. [0004] Due to the limitation of the capacity of the existing grid framework, the construction of an electric vehicle charging station involves a series of major issues such as the increase of the grid capacity and the adjustment of urban planning. Forming a network cannot be achieved overnight. At present, it ...
