[0041] The following is based on Figures 1 to 3 An electronic load control method, device, system, electronic device, and storage medium provided in embodiments of the present application are described.

[0042] The embodiment of the present application provides an electronic load control method, which is applied to an electronic load system. The electronic load system includes multiple electronic loads connected in parallel. The slopes of the output currents of the multiple electronic loads are adjustable, and the maximum slopes of the output currents of the multiple electronic loads are different. Figure 1 As shown, the method includes:

[0043] Step S100: obtaining a target current slope;

[0044] Step S200: obtaining the maximum slope of multiple electronic loads to obtain a slope set;

[0045] Step S300: traverse the elements in the slope set and sum the visited elements to obtain a slope sum result;

[0046] Step S400: If the slope summation result is greater than the target current slope, stop traversing;

[0047] Step S500: Based on the slope summation result and the target current slope, control the output current of multiple target electronic loads, and the sum of the slopes of the output currents of the multiple electronic loads is the target current slope. The target electronic load is the electronic load corresponding to the accessed element.

[0048] In an embodiment of the present application, a target current slope is obtained, and a slope set is obtained by obtaining the maximum slope of multiple electronic loads. Then, the elements in the slope set are traversed, and the accessed elements are summed to obtain a slope summation result. If the slope summation result is greater than the target current slope, the traversal is stopped. Based on the slope summation result and the target current slope, the output currents of multiple target electronic loads are controlled, and the sum of the slopes of the output currents of the multiple electronic loads is the target current slope, so that the slope of the output current of the electronic load system is the target current slope, thereby achieving precise control.

[0049] In step S100 , the target current slope is the slope of the output current required by the electronic load system.

[0050] In step S200 , the maximum slope of the electronic load is the maximum value of the controllable current slope that the electronic load can output;

[0051] In some embodiments of the present application, the step S300 of "traversing the elements in the slope set and summing the visited elements to obtain a slope summation result" is further described. The step S300 includes:

[0052] Step S310: sorting the elements in the slope set from large to small to obtain a slope sequence;

[0053] Step S320 sequentially accesses the elements of the slope sequence and sums the accessed elements to obtain a slope summation result.

[0054] In this embodiment, a slope sequence is obtained by sorting the elements in the slope set from large to small. When traversing the slope sequence, the elements of the slope sequence are accessed from large to small. This facilitates determining the minimum number of target electronic loads when comparing the slope summation result with the target current slope in subsequent steps, so that the slope summation result is greater than the target current slope, thereby improving the operating efficiency of the electronic system.

[0055] In some embodiments of the present application, the step S500 of “controlling the output currents of multiple target electronic loads based on the slope summation result and the target current slope” is further described. Step S500 includes:

[0056] Step S510: Divide the target current slope by the slope summation result to obtain a target weight;

[0057] Step S520: multiplying the maximum slopes of the multiple target electronic loads by the target weights respectively to obtain multiple target slopes, where the multiple target slopes correspond to the multiple target electronic loads;

[0058] Step S530 : controlling a plurality of target electronic loads to output currents at corresponding target slopes.

[0059] In this embodiment, the target weight is obtained by dividing the target current slope by the slope summation result, and the maximum slope of each target electronic load is multiplied by the target weight to obtain the corresponding target slope. Each target electronic load is controlled to output current with the corresponding target slope, so that the electronic load system outputs the target slope and realizes precise control of the output current.

[0060] For example, when two target electronic loads are determined, the target weight is calculated using the following formula:

[0061] k = A / (A1+A2);

[0062] Wherein, k is the target weight, A is the target current slope, A1 and A2 are the maximum slopes of the two target electronic loads respectively.

[0063] In addition, an embodiment of the present application provides a control device 100, which is applied to an electronic load system. The electronic load system includes multiple electronic loads connected in parallel. The slopes of the output currents of the multiple electronic loads are adjustable, and the maximum slopes of the output currents of the multiple electronic loads are different, such as Figure 2 As shown, the control device 100 includes:

[0064] A first acquisition module 110 is configured to acquire a target current slope;

[0065] A second acquisition module 120 is configured to acquire the maximum slope of a plurality of electronic loads to obtain a slope set;

[0066] A traversal summation module 130 is used to traverse the elements in the slope set and sum the visited elements to obtain a slope summation result;

[0067] A traversal stopping module 140 is configured to stop traversal if the slope summation result is greater than the target current slope;

[0068] The control module 150 is used to control the output currents of multiple target electronic loads based on the slope summation result and the target current slope, where the sum of the slopes of the output currents of the multiple electronic loads is the target current slope, and the target electronic load is the electronic load corresponding to the accessed element.
