Description

Technical Field
The application relates to the technical field of vehicle monitoring, in particular to a vehicle-mounted storage battery failure judging method and device.
Background
The storage battery is used as an uninterruptible power supply and has important significance in automobile parts. The storage battery is mainly responsible for starting an automobile engine and supplying power to an in-car electric control system so as to ensure the normal operation of the automobile. Whether the storage battery runs normally or not directly influences whether the automobile can be started by ignition or not. At present, most of automobiles still adopt lead-acid storage batteries, along with the increase of the driving time of vehicles, the polar surface of the lead-acid storage batteries can be vulcanized and corroded, so that the corrosion deformation of positive electrode grids, the falling and softening of positive electrode active substances, irreversible sulfation, thermal runaway and the like are caused, the performance of the lead-acid storage batteries is invalid, and when the battery capacity of the lead-acid storage batteries is reduced to 80% of the rated capacity, the capacity of the lead-acid storage batteries is possibly reduced sharply, the problems of serious swelling, acid leakage, air leakage and the like are caused, and the lead-acid storage batteries are possibly scrapped at any time. Meanwhile, the storage battery can also cause fire after being damaged, public safety is jeopardized, even explosion can be caused, personnel casualties are caused, and no equipment can detect the condition of the storage battery in real time at present.
For personal user vehicles, in the regular maintenance, the performance parameters of the vehicle-mounted lead-acid storage battery are detected, so that the fault and failure possibility of the storage battery can be effectively reduced, and the existing storage battery detection method mainly comprises the following steps: (1) Detecting an actual capacity of the vehicle-mounted storage battery by discharging; (2) Measuring the electric conductivity of the storage battery through an electric conductivity meter, and judging whether the storage battery fails; and (3) measuring battery parameters based on the vehicle-mounted sensor. In a usual vehicle environment, users can rarely adopt a professional testing method and a testing tool to carry out random inspection on the performance of the storage battery. Therefore, when the vehicle is not used for a long time or the vehicle-mounted electricity utilization instrument is forgotten to be closed, the problem of storage battery failure frequently occurs, and if the problem cannot be timely treated, the storage battery can be thoroughly damaged, and the economic losses such as the replacement of a new battery and the like can be avoided. Meanwhile, when the storage battery fails, the traditional field manual detection method can be generally carried out only on the site where the failure occurs, and the operation data and detailed failure information of the storage battery are difficult to obtain, so that the maintenance and the maintenance work of the storage battery become difficult and low-efficiency. Meanwhile, in the parking process of a large number of automobiles stored in an automobile warehouse, in order to master the electric quantity condition of a storage battery of a new automobile, workers are required to detect the automobile regularly, the workload is huge and low-efficiency, and therefore the existing storage battery management technology needs to be improved.
Aiming at the technical problem in the management of the vehicle-mounted storage battery, a novel vehicle-mounted storage battery failure judging technology is provided, and the vehicle-mounted storage battery failure judging technology aims at providing assistance for daily maintenance work of the vehicle-mounted storage battery.
