At present, new energy vehicles have been widely used, and the battery life of new energy vehicles has always been a technical problem in this field. In order to solve the problem of battery life of new energy vehicles, most of them currently use the method of setting charging piles to realize the battery power supply of new energy vehicles. The charging pile has the disadvantage of long charging time. Therefore, many manufacturers have changed their battery life thinking and designed a battery swap station. The battery swap station can take out the low-power battery of the vehicle and replace the high-power battery in the swap station with the vehicle. So as to solve the battery life problem of new energy vehicles.

The inventor noticed that all the battery swapping stations currently on the market directly charge all the batteries in the warehouse, so that the power of all the batteries in the swapping station reaches a relatively high level. Due to the influence of the surrounding car usage, all the batteries in the swap station cannot be swapped out. However, if all the batteries in the swap station are charged to a certain level, there are batteries that have been charged to a certain level and cannot be swapped out for use. In this case, there are problems of battery charging loss, resource loss to maintain a certain amount of power, and electricity price costs caused by charging the battery.

The applicant found that the charging control strategy of the battery in the swap station can be changed according to the actual operation of the swap station, so that the swap station can only charge the battery when the available battery is less than the preset value, thereby maintaining a certain availability. The number of batteries does not need to be fully charged to solve the problem of battery charging loss, resource consumption for maintaining a certain amount of power, and electricity price costs caused by battery charging.

According to some embodiments of the present application, an embodiment of the present application provides a battery charging control method, the battery charging control method can be applied in the control equipment of the power exchange station, wherein, the control equipment of the power exchange station (hereinafter referred to as station control for short) ) can specifically be computing devices such as servers and computers, as shown in Figure 1, the battery charging control method includes:

Step S100: Obtain the current available battery quantity of the battery swapping station.

Step S110: Detect whether the current available battery quantity is less than the first preset available battery quantity, and if so, go to step S120.

Step S120: Calculate the quantity difference between the current available battery quantity and the first preset available battery quantity.

Step S130: Select N target unusable batteries for charging, so that the current number of available batteries reaches the first preset number of available batteries.

In step S100, the currently available batteries in the swap station represent batteries with a remaining power higher than the first preset power in the swap station, wherein the remaining power can be represented by the state of charge (SOC) of the battery. The first preset power can be set according to the actual application scenario. For example, the first preset power is 90% of the total battery power, so the currently available battery in this solution means a battery with a remaining power higher than 90% of the total battery power.

As a possible implementation, the station control can obtain the battery status reported by each battery in the swap station, which includes the current remaining power of the corresponding battery. On this basis, the station control can use the current remaining power reported by each The power determines whether the corresponding battery belongs to the currently available battery, so that the number of batteries that belong to the currently available battery can be counted to know the number of currently available batteries in the swap station. Wherein, the station controller can communicate with the battery management system of each battery, so as to receive the battery status reported by the battery management system of the corresponding battery.

As another possible implementation, this solution can use a separate device to count the number of currently available batteries. For example, this solution can design a controller that can communicate with the battery management system of each battery in the swap station , so as to receive the battery status reported by the battery management system of each battery, the controller can count the number of batteries belonging to the currently available battery according to the current remaining power in the battery status of each battery. After the controller obtains the number of currently available batteries , the counted number of available batteries can be transmitted to the station control, so that the station control can know the current number of available batteries in the swap station.

In step S110, the current available battery quantity available to the station controller is compared with the first preset available battery quantity, so as to detect whether the current available battery quantity is lower than the first preset available battery quantity, wherein the first preset available battery quantity The quantity can be configured in the station control in advance, and the specific value of the first preset available battery quantity can be determined according to the historical battery usage of the swap station. For example, only half of the batteries in the swap station are replaced every day, then the first preset is available The number of batteries can be designed to be half of the number of all batteries in the swap station. Specifically, for example, the replacement station has a total of 48 batteries, and only 24 batteries can be replaced every day. In this case, the first preset number of available batteries can be designed as 24, that is, the station control detects whether the current number of available batteries is low Based on the number of batteries 24.

On the basis of step S110, if the station controller detects that the current available battery is lower than the first preset number of available batteries, in order to maintain a certain number of available batteries in the swap station, and prevent the replacement demand from being unsatisfied due to the lack of available batteries in the future, the station The controller may first perform step S120 to calculate the difference between the current available battery quantity and the first preset available battery quantity, and then perform step S130 to select N target unavailable batteries for charging, where N is the current available battery quantity and the first preset battery quantity. The quantity difference between the quantity of available batteries is set, and the current remaining quantity indicated by the non-available batteries is not higher than the first preset quantity of battery.

For example, the first preset number of available batteries is the aforementioned 24, and the current number of available batteries acquired by the station controller is 20. On this basis, the station controller can perform step S120 to calculate the quantity difference as 4, and then perform step S130 to select 4 target non-available batteries are charged, so that the current number of available batteries in the swap station reaches the first preset number of available batteries, so that when the swap station does not charge all the batteries, a certain number of available batteries can be maintained to meet the battery swap need.

In the battery charging control method designed above, this solution first obtains the current number of available batteries in the battery exchange station, and then compares the current number of available batteries with the first preset number of available batteries. When the current number of available batteries is lower than the first preset number of available batteries In the case of the quantity, this solution calculates the quantity difference N between the current available battery quantity and the first preset available battery quantity, and then selects N target unavailable batteries for charging. It can be concluded from the content of this scheme that only when the current number of available batteries is lower than the first preset number of available batteries, this scheme will select a certain number of target batteries for charging, so that the exchange station can maintain a certain number of available batteries. On this basis, this solution does not need to charge all batteries in the swap station indiscriminately, thereby reducing the situation that the batteries in the swap station are fully charged and cannot be swapped out for use, thereby reducing the loss of battery charging itself, the loss of power resources, and battery charging. bring about the cost.

According to some embodiments of the present application, the previous step S130 describes selecting N target unavailable batteries for charging. As a possible implementation, as shown in FIG. 2 , the specific target unavailable battery selection method may include the following steps:

Step S200: Obtain the remaining power of each unusable battery in the battery swapping station.

Step S210: Determine N target unavailable batteries according to the current remaining power of each unavailable battery.

Step S220: Charge N target unavailable batteries.

In the above-mentioned embodiment, the station controller first obtains the SOC of the remaining power of each unavailable battery in the switching station, and then determines N target unavailable batteries among all unavailable batteries according to the current remaining power of each unavailable battery, and finally The determined N target non-available batteries are charged.

As a possible implementation manner, for step S210, this solution can be specifically implemented through the following steps, as shown in Figure 3, including:

Step S300: Sort all unavailable batteries according to the current remaining power of each unavailable battery.

Step S310: Determining N unavailable batteries with lower remaining power in the ranking as target unavailable batteries.

In step S300, the station controller can sort all the unavailable batteries according to the current remaining power of each unavailable battery. Sort all non-available batteries from small or small to large, so as to form a sequence of non-available batteries sorted based on remaining power.

On the basis of the above, the station control can determine the N non-available batteries with lower remaining power in the sorting as the target non-available batteries. Select N non-available batteries in the direction of large, so as to obtain N target non-available batteries.

In the embodiment of the present application, the unavailable batteries are sorted based on the remaining power of the unavailable batteries, and then the N unavailable batteries with lower remaining power in the sorting are determined as the target unavailable batteries, so that the N unavailable batteries with lower remaining power Charging is performed so that the non-available battery with low remaining power becomes a usable battery after being charged, so that the non-available battery with low remaining power can be utilized, and the battery quality problem caused by the non-available battery with low remaining power not being used for a long time is avoided.

As another possible implementation, in addition to selecting the target non-available battery according to the remaining power of the battery, this solution can also select the target non-available battery based on the time when the non-available battery enters the power station, as shown in Figure 4 , may include the following steps:

Step S400: Obtain the time when each unusable battery currently enters the swap station in the swap station.

Step S410: Determine N target unavailable batteries according to the time when each unavailable battery enters the swap station.

Step S420: Charge N target unavailable batteries.

In the above embodiment, the station control can record the time when each battery enters the exchange station. On this basis, the station control can determine N target unavailable batteries according to the time when each unavailable battery enters the exchange station. The target is not available for charging the battery.

Specifically, for step S410, the station control can sort according to the length of time for each unavailable battery to enter the swap station from long to short or from short to long, and then the station control can start with the longest time to enter the swap station, and then Select N target non-available batteries based on the duration from long to short, so that the batteries that have been placed in the swap station for a long time can become available batteries for use, avoiding battery quality problems caused by batteries that have not been used for a long time.

According to some embodiments of the present application, optionally, this solution may also include the following solutions, as shown in Figure 5:

Step S500: Detect whether the battery swapping station has received an inbound battery, if so, go to step S510.

Step S510: Obtain the remaining power of the inbound battery.

Step S520: Determine whether to charge the inbound battery according to the remaining power of the inbound battery.

In step S500, the station controller can detect whether the swap station has received an inbound battery, wherein the inbound battery refers to a battery replaced by the swap station from the vehicle and entered into the swap station for charging.

As a possible implementation, the station controller can determine whether the station has received the inbound battery by detecting whether the Bluetooth connection with the inbound battery is completed. If the station controller completes the Bluetooth connection with the Bluetooth address of the inbound battery, it means The swap station receives the inbound battery. As another possible implementation, the station control can determine that the battery swapping station has received the incoming battery after the inbound battery contacts the plug in the corresponding position of the swapping station and is powered on.

On the basis of determining that the station control has received the inbound battery, the station control executes step S510 to obtain the remaining power of the inbound battery. Specifically, after the station control establishes a Bluetooth connection with the inbound battery, the battery management system in the inbound battery can report The remaining power of the inbound battery enables the station controller to obtain the remaining power of the inbound battery.

On the basis of the above, the station control can determine whether to charge the incoming battery according to the remaining power of the incoming battery, so as to realize the charging control of the incoming battery.

According to some embodiments of the present application, for step S520, as shown in FIG. 6 , it may be specifically implemented in the following manner:

Step S600: Detect whether the remaining power of the inbound battery is lower than the second preset power, if the remaining power of the inbound battery is lower than the second preset power, go to step S610; if the remaining power of the inbound battery is not less than For the second preset electric quantity, go to step S620.

Step S610: Charging the inbound battery until the remaining power of the inbound battery reaches the first preset power.

Step S620: Detect whether the current available battery quantity is less than the first preset available battery quantity, if the current available battery quantity is less than the first preset available battery quantity, go to step S610; if the current available battery quantity is not less than the first preset available battery quantity battery quantity, go to step S630.

Step S630: Do not charge the inbound battery.

In step S600, the second preset power is less than the first preset power, for example, the first preset power is 90% of the total battery power, then the second preset circuit can be designed to be 20% of the total battery power, that is, step S600 represents The station control detects whether the remaining power of the inbound battery is lower than 20% of the total battery power.

If the remaining power of the inbound battery is lower than the second preset power, it means that the power of the inbound battery is relatively low. On this basis, this solution does not care about the comparison between the current number of available batteries and the first preset number of available batteries. The inbound battery is directly charged until the remaining power of the inbound battery reaches the first preset power.

If the remaining power of the inbound battery is not lower than the second preset power, the station control will detect whether the current available battery quantity is less than the first preset available battery quantity, if the current available battery quantity is less than the first preset available battery quantity, then If the number of batteries currently available at the swap station is insufficient, then the inbound batteries can be charged until the remaining power of the inbound batteries reaches the first preset power level; If the number of currently available batteries is sufficient, the inbound battery will not be charged.

In this embodiment, the inbound battery is directly charged on the basis that the remaining power of the inbound battery is lower than the second preset power, and the currently available battery is charged on the basis that the remaining power of the inbound battery is not lower than the second preset power.

Step S700: Detect whether the current available battery quantity is greater than the second preset available battery quantity, and if the current available battery quantity is greater than the second available battery quantity, go to step S710.

Step S710: Do not charge the inbound battery.

In this embodiment, the second preset number of available batteries is greater than the first preset number of available batteries. For example, according to the aforementioned example, the first preset number of available batteries is designed to be 24, then the second preset number of available batteries can be designed as 40, that is, when the number of currently available batteries is greater than 40, the number of currently available batteries in the replacement station is relatively sufficient, and in this case, the inbound batteries can not be charged directly.

In the embodiment of the present application, when the number of currently available batteries is greater than the second preset number of available batteries, that is, when the number of currently available batteries in the swap station is relatively sufficient, the inbound batteries are not charged, so as not to affect the operation of the swap station. Realize resource and cost savings in the case of operational needs.

As another possible implementation, when the battery swapping station receives the inbound battery, before the station controller executes step S510 to obtain the remaining power of the inbound battery, as shown in Figure 8, this solution may also include the following solutions:

Step S800: Obtain the current price of electricity consumption.

Step S810: Detect whether the current electricity price is greater than the first preset electricity price, if so, go to step S820.

Step S820: Do not charge the inbound battery.

In this embodiment, the station controller can obtain the current electricity price, and then compare the current electricity price with the first preset electricity price. If it is greater than the first preset electricity price, it means that it is currently in peak electricity consumption, and The price of electricity is too high, and the price of electricity that is too high will increase the cost. On this basis, the station control will not charge the inbound battery. Wherein, the method for the station controller to obtain the current electricity price may include calling the grid data by the station controller, so as to obtain the electricity price of the grid.

According to some embodiments of the present application, optionally, as shown in FIG. 9, the solution may further include the following steps:

Step S900: Obtain the current electricity price.

Step S910: Detect whether the current electricity price is lower than the second preset electricity price, if so, go to step S920.

Step S920: Charge all the batteries in the swap station until the remaining power of all the batteries in the swap station reaches the first preset power.

In the above embodiment, when the current electricity price is lower than the second preset electricity price, this solution charges all the batteries in the swapping station until the remaining power of all the batteries in the swapping station reaches the first preset electricity price. Set power. Specifically, this solution can charge all the batteries in the swap station when the current electricity price is low during the off-peak period of the day, so as to achieve the purpose of saving costs.

As another possible implementation, the electricity price during the low power consumption period of the day is the lowest, and the time period of the low power consumption period of the day generally does not change. On this basis, the station control can obtain the current time. When the set low power consumption time period is reached, all batteries in the swap station are charged until the remaining power of all batteries in the swap station reaches the first preset power, thereby achieving the purpose of saving electricity cost.
