Embodiment Construction

[0040] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0041] Such as figure 1 As shown, an embodiment of the present invention provides a charging current overcurrent control method, including:

[0042] Step 11, obtaining the charging current value output from the on-board charger to the battery in the detection circuit;

[0043] Step 12, adjusting the charging current value according to the charging current value, a preset current protection value and a preset overcurrent count value;

[0044] Step 13, according to the adjusted charging current value, control whether the on-board charger stops working.

[0045] In the above embodiments of the present invention, the preset overcurrent count value is a ratio of the allowable overcurrent time of the charging current value to the detection period.

Abstract

The invention provides an overcurrent control method for charging current, an onboard charger and an automobile, and belongs to the technical field of vehicle control. The overcurrent control method for the charging current comprises the following steps: acquiring a charging current value output to a battery by the onboard charger in a detection loop; adjusting the charging current value according to the charging current value, a preset current protection value and a preset overcurrent count value; and controlling whether the onboard charger stops working or not according to the adjusted charging current value. Through adoption of the method, the onboard charger works in a state most close to an ideal charging current value; an overcurrent protection error operation caused by an overcurrent phenomenon of the onboard charger due to sampling interference is avoided; and the interference resistance and the reliability of the onboard charger are enhanced.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle control, and in particular relates to a charging current overcurrent control method, a vehicle charger and a vehicle. Background technique [0002] The overcurrent protection method of the charging current of the on-board charger in the prior art is: when the controller detects that the charging current is overcurrent, it immediately takes a protective action and shuts down the drive, thereby preventing the charger from continuing to output current. However, since the on-board charger operates in a high-power environment, the current value detected by the controller will be disturbed, and the existing protection control method will cause malfunction and affect the performance of the charger. Contents of the invention [0003] The purpose of the present invention is to provide a charging current overcurrent control method, a vehicle charger and an automobile, so as to solve the problem o...
