Embodiment Construction

[0008] The high-power battery test equipment sampling load mutation peak voltage algorithm is characterized in that: when the high-power battery test equipment load mutation is sampled by the AD sampling chip, the load voltage rise and fall values ​​of the high-power battery test equipment within N time intervals t, and Generate a high-power battery test equipment load sudden change voltage curve, with time as the x-axis and voltage as the y-axis in the high-power battery test equipment load sudden change voltage curve; then establish a high-power battery test equipment load sudden change voltage curve when the voltage rises The slope equation of the voltage rising line in the figure is y=k1×x+b1, where k1 is the slope of the rising line, b1 is the value of the intersection of the rising line and the y-axis coordinates, and the voltage curve of the load mutation of the high-power battery test equipment when the voltage drops The slope equation of the voltage drop line in the fi...

Abstract

The invention discloses an algorithm for sampling a voltage peak in the sudden change of the load of high-power battery test equipment. An AD sampling chip is utilized to sample the rising value and dropping value of load voltage within a certain time interval during the sudden change of the load of the high-power battery test equipment, a voltage curve graph for the sudden change of the load of the high-power battery test equipment is generated, and a voltage-rising straight line slope equation and a voltage-dropping straight line slope equation are then established; and finally, according to the slope equations, an intersectional voltage value between the voltage-rising straight line and the voltage-dropping straight line is worked out, and approximates the voltage peak in the sudden change of the load of the high-power battery test equipment.

Description

technical field [0001] The invention relates to the field of battery detection methods, in particular to a high-power battery test equipment sampling load mutation peak voltage peak algorithm. Background technique [0002] During the load mutation process of high-power battery test equipment, the output voltage will have a rapid rising phase and a rapid falling phase. Since the AD sampling chip needs a certain sampling processing time, and the voltage rise and fall time is very short, it is very difficult to sample the peak value of the sudden load voltage rise of the high-power battery test equipment. If the maximum voltage obtained by AD sampling is used as The disadvantage of the rising peak value of the voltage is that the sampled voltage value may be in the rising area or in the falling area, and the sampled voltage peak value is not accurate enough. Contents of the invention [0003] The purpose of the present invention is to provide a high-power battery testing e...
