Problems solved by technology
However, the fitting formula does not consider the influence of the internal electrochemical mechanism of the battery on the service life of the battery, making it difficult to quantify the relationship between the DOD (depth of charge and discharge) and service life of the battery
Therefore, the DOD of the battery cannot be accurately controlled by the third method, so that the service life of the battery reaches the target service life

The invention discloses a battery charging and discharging depth control method and system, an automobile and a storage medium. The control method comprises the following steps: acquiring the service life of the battery, determining that the service life is less than a first preset threshold value, and updating the charge-discharge depth of the battery according to a preset first charge-discharge depth parameter; determining that the used life is greater than or equal to a first preset threshold; obtaining operation parameters, obtaining a second charge-discharge depth parameter according to the operation parameters and a preset relation, and updating the charge-discharge depth according to the second charge-discharge depth parameter; determining that the used life is less than the target service life; and determining that the variation of the used life after the charge-discharge depth is updated is greater than or equal to a second preset threshold value, and executing the step of acquiring the operation parameters again. According to the invention, the relationship between the charge-discharge depth and the service life of the battery can be quantified, so that the service life reaches the target service life by controlling the charge-discharge depth.
Description
technical field [0001] The present application relates to the field of battery technology, and in particular to a method for controlling battery charge and discharge depth, a control system, a vehicle, and a storage medium. Background technique [0002] In related technologies, the following three methods are used to prolong the service life of the battery to control the service life of the battery to reach the target service life: the first one is to use an active or passive thermal management system to make the battery run in a suitable temperature range; The first is to reduce the current used by the battery to avoid overheating, overpotential lithium analysis, etc.; the third is to avoid deep charging and deep discharging of the battery. [0003] In practical applications, the first and second methods achieve the above effects by setting the battery temperature threshold, current threshold, etc., and the third method achieves the above effects by adopting semi-empirical ...
