With the development of new energy technology, the application fields of batteries are becoming more and more extensive. For example, they can be used as a power source to power vehicles and reduce the use of non-renewable resources. When the power of the battery in the vehicle is not enough to support the continued driving of the vehicle, charging equipment such as charging piles can be used to charge the vehicle, that is, to charge the battery in the vehicle to realize the cycle of charging and discharging the battery. Alternatively, battery replacement services can also be provided for vehicles through battery swapping stations, that is, the batteries can be quickly removed or installed from the vehicle. The battery removed from the vehicle can be placed in the battery storage mechanism of the battery swap station for charging in preparation for battery swapping for subsequent vehicles entering the battery swap station.

After the battery has been used for a period of time or a certain number of cycles, the performance of the battery may change. For example, the state of health (SOH) of the battery may decay with the use of the battery. If the cost of a new battery is still calculated based on its SOH, it will cause inaccurate billing and cause losses to users or operators. In addition, as the battery is used, the battery's state of charge (SOC) may also lead to inaccurate measurement results due to the accumulation of errors. If billing is still based on the SOC directly measured by the battery, the same problem will occur. This results in inaccurate billing and losses to users or operators.

In view of this, embodiments of the present application provide a method for battery replacement. The correction model in the server is used to correct the battery parameters of the battery. The actual battery parameters of the first battery can be used for billing, and the battery can be avoided.

This application provides a method for battery replacement, as shown in Figure 2. The method 200 shown in FIG. 2 may be executed by a server, such as the cloud server 152 in FIG. 1 . Optionally, method 200 can also be applied to battery management systems, battery replacement equipment, and other devices that can process battery-related parameters. It should be understood that this application does not limit the device for executing method 200, that is, any device that can process relevant parameters of the battery is applicable to the embodiment of this application. Method 200 may include at least some of the following.

S220: Obtain the first battery parameters of the first battery. The first battery is a battery replaced by the electrical equipment;

S230: Obtain the second battery parameters according to the first battery parameters and the correction model. The correction model is used to determine the second battery parameters according to the usage of the first battery. The second battery parameters are used to charge the first battery.

The first battery is an old battery that has been used in the electrical equipment. When the electrical equipment needs to replace the battery, the power replacement equipment can replace the first battery and then replace the electrical equipment with a new battery. In the process of charging for this power exchange, the BMS of the first battery may send the relevant parameters of the first battery to the server, so as to facilitate the charging of this power exchange process. Among them, the parameter related to charging is the first battery parameter. For example, the first battery parameter may be the SOC, SOH, etc. of the first battery.

Considering that when the BMS determines the first battery parameter of the first battery, the measurement of the first battery parameter is usually inaccurate due to the error of the ampere-hour integration method, the server can correct the received first battery parameter and Use corrected battery parameters for billing. The corrected battery parameters are the second battery parameters.

The specific billing method may be that after the server corrects the first battery parameters, billing is based on the second battery parameters; or it may be that after the server corrects the first battery parameters, the obtained second battery parameters are sent to the battery replacement device. Billing is done by the power exchange equipment.

In the process of correcting the first battery parameters according to the correction model, the server can obtain the first battery parameters measured by the BMS, and input the first battery parameters into the correction model to obtain the second battery parameters. The first battery parameter may be the current battery parameter obtained by the BMS using the ampere-hour integration method, for example, the current SOC of the first battery; or it may be the latest battery parameter recorded in the BMS, for example, the SOH after the last correction.

The correction model can correct the first battery parameter according to the usage degree of the first battery, and the usage degree of the first battery is the usage status of the first battery. Specifically, if the first battery is used for a longer time or is used more frequently, it means that the usage of the first battery is higher, and various performance parameters of the battery may change greatly; if the first battery is used for a shorter time or is used more frequently, If it is low, it means that the usage of the first battery is low, and the changes in various performance parameters of the battery may be small. The correction model can fully consider the impact of the usage status of the first battery on the first battery parameters, and implement the correction of the first battery parameters through calculation.

The correction model may be a neural network, for example. In the process of training the correction model, the first battery parameters and actual battery parameters of the same type or model of the first battery under different usage conditions can be obtained, and the calculation parameters in the correction model can be adjusted so that the The second battery parameters obtained after the first battery parameters are input into the calibration model match the actual battery parameters of the first battery, that is, within a certain error range, the battery parameters output by the calibration model can be considered accurate. Among them, the first battery parameters refer to the battery parameters immediately measured by the BMS when the first battery is used to a certain extent, and the actual battery parameters refer to the parameters measured by the BMS after a certain correction process has been performed on the first battery. Battery parameters.

By correcting the first battery parameters through the correction model, the actual battery parameters of the first battery can be used for billing, thereby avoiding errors caused by the BMS when measuring the first battery parameters, resulting in inaccurate billing. At the same time, the correction model corrects the first battery parameter, and the corrected battery parameters can be obtained quickly, so that the billing results can be pushed to the user in a timely and accurate manner, improving the user experience.

According to some embodiments of the present application, optionally, the method 200 may further include the following steps.

S210: Receive a first power exchange instruction from the power exchange device. The first power exchange instruction is used to instruct the server to correct the first battery parameter.

When the power replacement device confirms that the power-consuming device needs to replace the battery, it can send a first power replacement instruction to the server to trigger the server to correct the first battery parameters of the first battery. This can ensure that the battery parameters used for billing are accurate. of. After receiving the first battery replacement instruction, the server may correct the latest first battery parameter recorded in the server.

According to some embodiments of the present application, optionally, method 200 further includes: sending a second power replacement instruction to the battery management system, where the second power replacement instruction is used to instruct the electrical equipment to replace the first battery.

The first power replacement instruction may only be used to instruct the server to correct the first battery parameter, while the second power replacement instruction may be used to instruct the BMS to perform a power replacement operation. In a possible implementation, as shown in step S211 in FIG. 3 , the server sends a second power replacement instruction to the BMS. In this case, the second battery replacement command can also be used to request the BMS to provide the first battery parameters to the server, so that the server can make corrections based on the first battery parameters provided by the BMS.

Or, in another possible implementation, as shown in step S212 in Figure 3, the power exchange device sends a second power exchange instruction to the BMS, and the BMS can execute what the BMS needs to perform according to the instructions of the second power exchange instruction. battery replacement operation.

In a possible implementation, the server can correct the SOC required for billing based on multiple SOCs of the first battery during use. For example, every first time interval or first number of cycles, the BMS sends the first SOC of the first battery to the server. The server can calculate the trend of SOC changes with time or with the number of cycles based on the received first SOC, and when billing is required, the first battery parameter can be corrected based on the trend of changes.

In another possible implementation, the server can also correct each received SOC and feed it back to the BMS, so that the BMS can obtain the corrected SOC in real time during the use of the first battery, thereby being able to provide Users provide more accurate SOC.

According to some embodiments of the present application, optionally, the first battery parameter is the health state SOH of the first battery, the correction model is the SOH correction model, and the second battery parameter is the second SOH.

The SOH of a battery can usually be defined from the perspective of battery capacity or battery charge. For example, SOH can be the percentage of the battery's current capacity to the battery's rated capacity, or it can be the percentage of the current battery's maximum discharge capacity to the new battery's maximum discharge capacity. The SOH of the first battery will attenuate with the usage time or number of uses of the first battery, and the actual power used by the first battery will also be affected by the SOH. Specifically, the server can use the SOH correction model to correct the SOH of the first battery according to the usage of the first battery, such as the cumulative usage time or the cumulative number of cycles.

According to some embodiments of the present application, optionally, step S220 may include: receiving a first SOH from the BMS, where the first SOH is the SOH of the first battery recorded at the last charging time.

Each time the first battery is billed, the server will correct the first battery parameters and use the corrected battery parameters, that is, the second battery parameters, for billing.

During the power replacement process, the power replacement equipment needs to replace the old battery that has been used in the electrical equipment, and then replace the old battery with a new battery for the electrical equipment. The old battery that is replaced is the first battery, and the new battery that is replaced is the first battery. for the second battery. When charging the battery replacement process of the first battery, the battery replacement equipment needs to obtain relevant battery parameters of the second battery in addition to the relevant battery parameters of the first battery. The second battery can be stored at a battery swap station before being replaced, and the battery parameters related to the second battery can be directly measured by the BMS of the second battery. Therefore, when the BMS of the first battery determines that the first battery parameter of the first battery needs to be corrected, the battery replacement device performs billing based on the second battery parameter of the first battery and the third battery parameter of the second battery; When the BMS of the first battery determines that the first battery parameter of the first battery does not need to be corrected, the power exchange device performs billing based on the first battery parameter of the first battery and the third battery parameter of the second battery.

In a possible implementation, before replacing the second battery with the electrical device, an instruction may also be issued to the second battery to instruct the BMS of the second battery to determine whether battery parameters related to the second battery need to be corrected. When the battery parameters of the second battery need to be corrected, the BMS of the second battery sends the corrected battery parameters to the battery replacement device, then the third battery parameters are the corrected battery parameters; when there is no need to correct the battery parameters of the second battery. When the battery parameters of the second battery are corrected, the BMS of the second battery directly sends the obtained battery parameters to the battery replacement device, then the third battery parameters are the battery parameters that have not been corrected.

According to some embodiments of the present application, optionally, the power exchange equipment can be charged according to the following formula (1).

F＝(SOC ₂ ×E ₂ ×SOH ₂ -SOC ₁ ×E ₁ ×SOH ₁ )×f ₁ (1)

Battery parameters, E ₂ is the total power of the second battery, and f ₁ is the unit price of the power.

When charging the first battery, the battery swapping device may specifically charge according to the above formula (1). Formula (1) is to subtract the actual power of the first battery from the actual power of the second battery, and then multiply the difference by the unit price of the power, which is the fee that the user needs to pay. In formula (1), the SOC and SOH of the first battery are the actual battery parameters of the first battery, that is, when correction is required, SOC ₁ and/or SOH ₁ are the corrected battery parameters; when correction is not required, In the case of correction, it can be considered that the SOC ₁ and/or SOH ₁ directly obtained by the BMS are accurate.

According to some embodiments of the present application, optionally, method 201 further includes: the power replacement device determines the number of batteries to be replaced; and performs billing based on the first battery parameter or the second battery parameter and the number of batteries to be replaced.

In a possible implementation, multiple batteries can be installed on the same power-consuming device. During the power replacement process, the power-exchange device can also determine the number of batteries to be replaced, and charge based on the number of batteries to be replaced. For example, when replacing an old battery, the electrical equipment only replaces one first battery; when replacing a new battery for the electrical equipment, the electrical equipment requires multiple second batteries to be replaced. Similarly, when replacing old batteries, the electrical equipment replaces multiple first batteries; when replacing new batteries for the electrical equipment, the electrical equipment only needs to replace one second battery. Then, when charging the battery replacement process, the battery replacement equipment needs to consider the difference in the quantity of the first battery and the second battery. Specifically, the battery replacement equipment may be charged based on the difference in quantity between the first battery and the second battery, or may be charged based on the number of batteries replaced or batteries replaced.

According to some embodiments of the present application, optionally, the power exchange equipment can be billed according to the following formula (2).

F＝(SOC ₂ ×E ₂ ×SOH ₂ -SOC ₁ ×E ₁ ×SOH ₁ )×f ₁ +f ₂ ×n (2)

When the number of batteries replaced by the electrical equipment is different from the number of batteries replaced, the billing can be carried out specifically according to the above formula (2). Formula (2) is based on formula (1) and adds the calculation of the basic cost of the battery. Among them, f ₂ is the basic cost of a battery, and n can be the number of batteries replaced or the number of batteries replaced, or it can be the difference between the two.
