Description
Technical Field
The invention relates to the field of automobile storage batteries, in particular to a storage battery monitoring method, a storage battery monitoring device and a storage medium.
Background
In the automobile design and development process, the longest parking time and the maximum static current value are taken as one of the important factors for the selection of the storage battery capacity. However, in some special cases, because a user installs additional electric equipment, such as a driving recorder, an entertainment system, a look-around system, and the like, the quiescent current of the whole vehicle may exceed the design size; on the other hand, the design strategy of the original parts may be incomplete, and under a special working condition, the original parts may not sleep or abnormally wake up, so that the electric quantity of the storage battery is continuously consumed, and the power shortage is caused. The electricity shortage phenomenon is accidental, the situation of use needs to be continuously simulated for testing when problems are checked, the checking time is long, the difficulty is high, and the efficiency is low.
The storage battery is insufficient in power, so that the vehicle cannot be started, and if effective early warning measures cannot be provided, unnecessary troubles are caused to the vehicle owner. At present, the voltage value of a storage battery is mainly collected through a vehicle-mounted terminal in the market, whether the voltage value of the storage battery is lower than a preset fixed voltage threshold value or not is judged, and when the voltage value of the storage battery is lower than the preset fixed voltage threshold value, pushing early warning is carried out through an application program or a short message.
In addition, as the service life of the vehicle increases, the driving mileage increases, the quality of the storage battery is also reduced, and the residual life is less and less, namely, the storage battery is aged. When the storage battery is seriously aged, the vehicle cannot be started, the entertainment system cannot be used, the anti-theft system fails to authenticate and the like, and the normal vehicle using experience of a user is influenced. Therefore, it is important to judge the deterioration of the battery.
The ordinary user judges the aging of the storage battery generally through the service life of the vehicle (for example, more than 5 years), the driving mileage (for example, more than 10 kilometers), and the power shortage time (for example, changing from 1 month to 1 week). For the 4s store, the parameters stored in the storage battery controller can be read by the diagnostic instrument for analysis. Furthermore, the storage battery SOH (State of Health ) is mainly collected through a vehicle-mounted terminal in the market, whether the storage battery SOH is lower than a preset fixed SOH threshold value or not is judged, and when the storage battery SOH is lower than the preset fixed SOH threshold value, pushing and early warning are carried out through an application program or a short message.
However, in the research process, the inventor of the present application finds that, for the insufficient power or the aging of the storage battery, if the preset fixed voltage threshold or the preset fixed SOH threshold is set too high, false alarm may be caused, and unnecessary disturbance may be caused to the user, whereas, if the preset fixed voltage threshold or the preset fixed SOH threshold is set too low, late alarm may be caused, and at this time, the vehicle storage battery is insufficient or aged, and the early warning to the user may be meaningless.
