Specifically, the data of the preset emptying correction condition can be stored in a cloud end, the battery replacement equipment can periodically acquire the data of the preset emptying correction condition from the cloud end, or the preset emptying correction condition data is acquired from the cloud end again after a new battery is received each time, so that a supplier of the battery replacement equipment can update each battery replacement equipment only by updating the cloud end data; and secondly, the data of the preset emptying correction condition can be stored in the battery replacement equipment.
And if the historical emptying correction record can meet the preset emptying correction condition, discharging the battery until the residual electric quantity of the battery reaches the preset electric quantity, executing a preset emptying correction strategy to perform emptying correction on the battery, and releasing the battery subjected to emptying correction for a client to take.
It is understood that the preset amount of electricity may refer to an amount of electricity, or may refer to a percentage of remaining electricity to a battery capacity. And secondly, emptying the corrected battery for users to use. The battery replacement equipment is internally provided with a structure or a device which can accommodate and open the battery.

It will be appreciated that the historical purge correction records include, but are not limited to, the last purge correction time, and may be adjusted according to the design requirements of the product, for example, data such as the total usage time or the number of charges of the battery may be recorded and monitored based on the average service life of the battery. The last emptying correction time refers to the time point of the last emptying correction of the battery.
Specifically, after a user places a battery in the battery replacement equipment, the controller calculates the interval time between the last emptying correction time of the battery and the current time, then compares the interval time with preset time, if the interval time is greater than or equal to the preset time, judges that the historical emptying correction record of the battery meets the preset emptying correction condition, discharges the battery to preset electric quantity and executes a preset emptying correction strategy to perform emptying correction on the battery. The predetermined time may be flexibly set according to the type of the battery, an application scenario, an attenuation rate, or the like, for example, the predetermined time may be set to 30 days, and if the battery is not subjected to the vent correction for at least 30 consecutive days, it is determined that the battery satisfies the vent correction condition.

As can be understood, the preset time period may be set as the peak use period of the battery replacement device, so as to facilitate the use of the user; for example, the meal delivery time and the commute time at noon or evening are set as the preset time periods, so that the situation that the battery replacement equipment cannot be used due to emptying correction of too many batteries in a peak period can be avoided, a user can complete battery replacement as soon as possible in the peak period, and the use convenience is improved.
It can be further understood that if the battery is put into the battery after the preset time period, whether the historical emptying correction record of the battery meets the preset emptying correction condition is judged, so that the battery replacement device is guaranteed to be supplied to a user for use at a higher priority level in a use peak period.
As shown in fig. 1, if the preset electric quantity may be zero electric quantity in some embodiments, the performing the preset emptying correction strategy to empty the battery includes: and charging the battery from zero electric quantity to full charge capacity, and taking the full charge capacity as a emptying correction value.
It can be understood that the step of presetting the blowdown correction strategy specifically includes: discharging the battery until the residual electric quantity in the battery is reduced to zero; charging a battery with zero electric quantity, recording the electric quantity value consumed by fully charging the battery, and taking the electric quantity value consumed by fully charging the battery as the emptying correction value of the battery; the purpose of updating the capacity of the battery is achieved, and the SOC precision of the battery is improved.
Specifically, a charging circuit or other devices or mechanisms capable of charging the battery, such as a charging circuit, are arranged in the battery replacement equipment; next, the battery replacement device is provided with a structure, a device, or a mechanism capable of recording the consumption amount of the battery charging amount.
As shown in fig. 1, in the active empty correction method for a battery in some embodiments, if the historical empty correction record meets the preset empty correction condition, the method further includes, before discharging the battery, the steps of:
and acquiring the remaining capacity ratio of the battery.
It can be understood that, the electric quantity detection module detects the current battery, obtains the remaining electric quantity value of the current battery, and calculates the remaining electric quantity ratio of the current battery by combining the capacity value of the current battery. Specifically, the capacity value of the current battery can be acquired through the cloud, and the capacity value of the current battery can be acquired through a storage unit arranged in the battery or the battery replacement equipment.
Judging whether the residual electric quantity ratio is less than or equal to a preset electric quantity ratio or not; and if so, discharging the battery until the residual electric quantity of the battery reaches the preset electric quantity.
As can be appreciated, the controller compares the remaining capacity ratio of the current battery with a preset capacity ratio. And if the residual electric quantity ratio of the battery is smaller than or equal to the preset electric quantity ratio, discharging the battery until the residual electric quantity reaches the preset electric quantity, and then executing a preset emptying correction strategy to perform emptying correction on the battery. If the residual electric quantity ratio of the battery is larger than the preset electric quantity ratio, fully charging the electric quantity of the battery for a user needing to change the battery to replace the battery; therefore, the battery replacing device can be prevented from replacing the battery with higher residual power, and unnecessary power consumption is reduced.
As shown in fig. 1, in the active battery drain correction method in some embodiments, the remaining capacity ratio is the percentage of the remaining capacity to the battery capacity.
As can be appreciated, the remaining capacity ratio is the remaining capacity value of the current battery/the capacity value of the current battery; the current capacity value of the battery may be obtained from a cloud or other storage unit.
As shown in fig. 1, in the active empty correction method of the battery in some embodiments, the preset charge ratio is 30%.
It can be understood that if the remaining power ratio exceeds 30%, the battery is directly fully charged for the user to replace the power, so that the battery is prevented from discharging when the power is large, the time from recycling to waiting for use of a single battery is prevented from being prolonged due to overlong discharging time, the working efficiency of the battery replacement equipment is effectively improved, and the power consumption of the battery replacement equipment is also reduced.
Specifically, a recovery unit can be arranged in the battery replacement device to recover electric quantity released by the battery during discharging, and the recovered electric energy can be used for energy consumption of the battery replacement device or charging the battery, so that the energy consumption of the battery replacement device is effectively reduced.
