Embodiment Construction

[0059] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0060] figure 1 It is a flow chart of a method for detecting static current of a vehicle provided by an exemplary embodiment. Such as figure 1 As shown, the method may include the following steps:

[0061] Step S101, collect the discharge amount of the storage battery of the vehicle.

[0062] Step S102, if the vehicle wakes up again after sleeping, determine the duration of the sleeping.

[0063]Step S103, determining the amount of change of the discharge amount during the sleep period according to the collected discharge amount.

[0064] Step S104, determining the quiescent current value of the vehicle according to the variation of the discharge amount ...

Abstract

The invention relates to a vehicle quiescent current detection method and device, a medium, equipment and a vehicle. The method comprises the steps of collecting the discharge capacity of a storage battery of a vehicle; if the vehicle is awakened after dormancy, determining the dormancy duration; determining the variation of the discharge capacity in the dormancy period according to the collecteddischarge capacity; and determining a quiescent current value of the vehicle according to the variation of the discharge capacity and the dormancy duration. Compared with the mode of directly detecting the quiescent current in the prior art, the scheme has the advantages that the detection precision of the quiescent current of the vehicle is improved, and the quiescent current of the vehicle is more truly reflected, so that the potential safety hazard of the vehicle is favorably monitored, and the safety of the vehicle is improved.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle detection, and in particular, to a detection method and device, a medium, a device, and a vehicle for static current of a vehicle. Background technique [0002] Static current refers to the current supplied by the battery when the vehicle is at rest (ignition switch OFF). That is, the battery of the vehicle will also "discharge" when it is not working, generating a discharge current, which is affected by the insulation strength of the battery. The discharge current of newer batteries is small, about microampere to milliampere level, but some batteries have a large discharge current, and some parts will heat up severely (such as at the joints), which may cause the battery to catch fire. [0003] A vehicle equipped with a battery sensor (Electric Battery Sensor, EBS) can detect the quiescent current value of the vehicle, but what it detects is only the minimum value of the quiescent curren...
