随着新能源技术的发展,电池的应用领域越来越广泛,如可作为动力源为车辆提供动力,减少不可再生资源的使用。在车辆中电池的电量不足以支持车辆继续行驶的情况下,可利用充电桩等充电设备对车辆进行充电,即对车辆中的电池进行充电,以实现电池的充、放电循环使用。或者,也可以通过换电站为车辆提供电池更换服务,即电池可以从车辆上快速取下或者安装。从车辆上取下的电池可以放入换电站的电池存放机构中进行充电,以备为后续进入换电站的车辆进行换电。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.
电池在使用了一段时间或一定循环圈数后,电池的性能可能会发生改变,例如电池的健康状态(state of health,SOH),可能会随着电池的使用而产生衰减。如果仍然按照新电池的SOH来计算该电池的费用,则会造成计费不准确,给用户或运营商带来损失。另外,随着电池的使用,电池的荷电状态(state of charge,SOC)也有可能因为误差的积累而导致测量结果的不准确,如果仍然按照该电池直接测量得到的SOC进行计费,同样会造成计费不准确,给用户或运营商带来损失。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.
鉴于此,本申请实施例提供了一种用于电池换电的方法,利用服务器中的校正模型对电池的电池参数进行校正,能够以第一电池的实际电池参数进行计费,能够避免对电池参数进行测量时产生误差,而导致的计费不准确,从而提高计费的准确性。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. Errors occur when parameters are measured, resulting in inaccurate billing, thereby improving billing accuracy.

第一电池为用电设备中已使用的旧电池,在用电设备需要更换电池时,换电设备可以将第一电池换下,再为用电设备换上新电池。在对该次换电进行计费的过程中,第一电池的BMS可以将第一电池的相关参数发送给服务器,以便于对该次换电过程计费。其中,与计费有关的参数即为第一电池参数。例如,第一电池参数可以是第一电池的SOC、SOH等。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.
考虑到BMS在确定第一电池的第一电池参数时,通常会由于安时积分法的误差而导致第一电池参数的测量不准确,因此服务器可以对接收到的第一电池参数进行校正,并将校正后的电池参数用于计费。其中,校正后的电池参数即为第二电池参数。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.
具体计费方式可以是服务器对第一电池参数校正后,根据第二电池参数进行计费;也可以是服务器对第一电池参数进行校正后,将得到的第二电池参数发送给换电设备,由换电设备进行计费。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.

在根据校正模型对第一电池参数进行校正的过程中,服务器可以获取到BMS测量得到的第一电池参数,并将第一电池参数输入校正模型,得到第二电池参数。其中,第一电池参数可以是BMS以安时积分法获取到当前的电池参数,例如,当前第一电池的SOC;也可以是BMS中最新记录的电池参数,例如,上一次校正后的SOH。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.
校正模型可以根据第一电池的使用度来对第一电池参数进行校正,第一电池的使用度即为第一电池的使用状况。具体地,第一电池使用时间较长或者使用得较为频繁,则说明第一电池的使用度较高,电池的各项性能参数的变化可能较大;第一电池使用时间较短或使用频率较低,则说明第一电池的使用度较低,电池的各项性能参数的变化可能较小。校正模型可以充分考虑到第一电池的使用状况对第一电池参数的影响,并通过计算来实现对第一电池参数的校正。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.
校正模型可以例如是神经网络。在对校正模型进行训练的过程中,可以获取同一类型或同一型号的第一电池在不同使用度的情况下的第一电池参数和实际电池参数,并调整校正模型中的计算参数,使得在将第一电池参数输入校正模型后得到的第二电池参数,与第一电池的实际电池参数相匹配,即在一定误差范围内,可以认为校正模型输出的电池参数是准确的。其中,第一电池参数指的是第一电池在使用到一定程度时由BMS立即测量得到的电池参数,实际电池参数指的是对第一电池进行了一定的校正处理后再由BMS测量得到的电池参数。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.

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.

第一换电指令可以仅用于指示服务器对第一电池参数进行校正,而利用第二换电指令指示BMS执行换电操作。在一种可能的实施方式中,如图3中的步骤S211所示,由服务器向BMS发送第二换电指令。在这种情况下,第二换电指令也可以用于请求BMS向服务器提供第一电池参数,以便于服务器能够基于BMS提供的第一电池参数进行校正。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.
或者,在另一种可能的实施方式中,如图3中的步骤S212所示,由换电设备向BMS发送第二换电指令,则BMS可以根据第二换电指令的指示执行BMS需要执行的换电操作。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.
通过向BMS发送第二换电指令,可以在换电设备与BMS之间不进行通信的情况下,完成换电操作。同时,BMS在接收到第二换电指令的情况下,可以向服务器提供计费所需的相关电池参数,有利于服务器对第一电池参数进行校正,从而提高计费的准确性。By sending the second power swap command to the BMS, the power swap operation can be completed without communication between the power swap device and the BMS. At the same time, when the BMS receives the second battery replacement instruction, it can provide the server with relevant battery parameters required for billing, which helps the server correct the first battery parameters, thereby improving the accuracy of billing.
根据本申请的一些实施例,可选地,第一电池参数为第一电池的荷电状态SOC,校正模型为SOC校正模型,第二电池参数为第二SOC。According to some embodiments of the present application, optionally, the first battery parameter is the state of charge SOC of the first battery, the correction model is the SOC correction model, and the second battery parameter is the second SOC.
具体地,服务器可以利用SOC校正模型,根据第一电池的使用度,例如累计使用时长或累计循环圈数,来对第一电池的SOC进行校正。Specifically, the server can use the SOC correction model to correct the SOC of the first battery according to the usage of the first battery, such as the cumulative usage time or the cumulative number of cycles.
利用SOC校正模型对第一电池的SOC进行校正,可以避免BMS在测量SOC时存在的误差导致计费不准确,保证用于计费的SOC是准确的,提高计费的准确性。Using the SOC correction model to correct the SOC of the first battery can avoid errors in BMS measurement of SOC that lead to inaccurate billing, ensure that the SOC used for billing is accurate, and improve billing accuracy.
根据本申请的一些实施例,可选地,步骤S220可以包括:以第一时间间隔或第一循环圈数间隔从BMS接收第一SOC。According to some embodiments of the present application, optionally, step S220 may include: receiving the first SOC from the BMS at a first time interval or a first cycle interval.
在一种可能的实施方式中,服务器可以根据第一电池在使用过程中的多个SOC,对计费时需要用到的SOC进行校正。例如,每隔第一时间间隔或第一循环圈数,BMS向服务器发送第一电池的第一SOC。服务器则可以根据接收到的第一SOC, 计算SOC随时间或随循环圈数变化的趋势,在需要计费时,结合该变化趋势,对第一电池参数进行校正。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.
在另一种可能的实施方式中,服务器也可以对接收到的每一个SOC进行校正,并反馈给BMS,使得BMS在第一电池的使用过程中也能够实时获得校正后的SOC,从而能够为用户提供更加准确的SOC。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.
这样可以为第一SOC的校正提供更多参数,有利于服务器在对第一SOC校正的过程中能够输出更加准确的第二SOC,从而提高计费的准确性。This can provide more parameters for the correction of the first SOC, which helps the server to output a more accurate second SOC during the process of correcting the first SOC, thereby improving the accuracy of billing.
根据本申请的一些实施例,可选地,第一电池参数为第一电池的健康状态SOH,校正模型为SOH校正模型,第二电池参数为第二SOH。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.
电池的SOH通常可以从电池容量或电池电量的角度来定义。例如,SOH可以是电池当前容量占电池额定容量的百分比,或者,可以是当前电池最大放电电量占新电池最大放电电量的百分比。第一电池的SOH会随着第一电池的使用时间或使用次数而衰减,第一电池实际使用的电量也会受到SOH的影响。具体地,服务器可以利用SOH校正模型,根据第一电池的使用度,例如累计使用时长或累计循环圈数,来对第一电池的SOH进行校正。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.
利用SOH校正模型对第一电池的SOH进行校正,可以在计费时利用准确的SOH进行计费,从而避免第一电池的SOH对第一电池的实际SOC造成影响而导致计费不准确,提高计费的准确性。By using the SOH correction model to correct the SOH of the first battery, the accurate SOH can be used for billing, thereby avoiding the impact of the SOH of the first battery on the actual SOC of the first battery, resulting in inaccurate billing, and improving Accuracy of billing.
根据本申请的一些实施例,可选地,步骤S220可以包括:从BMS接收第一SOH,第一SOH为第一电池的在上一次计费时记录的SOH。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.
在每一次对第一电池进行计费时,服务器都会对第一电池参数进行校正,并将校正后的电池参数,即第二电池参数,用于计费。服务器也可以在每次校正后储存第一电池的第二电池参数,例如第二SOH,在下一次对第一电池的SOH进行校正时,以上一次校正后的第二SOH作为本次校正的第一SOH,再次进行校正。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. The server can also store the second battery parameter of the first battery after each calibration, such as the second SOH. When the SOH of the first battery is calibrated next time, the second SOH after the last calibration will be used as the first parameter of this calibration. SOH, calibrate again.
可选地,服务器得到第二电池参数后,可以将第二电池参数发送给BMS,在下一次计费时,由BMS再将上一次计费时记录的电池参数提供给服务器。Optionally, after the server obtains the second battery parameters, it can send the second battery parameters to the BMS. During the next billing, the BMS will provide the battery parameters recorded during the last billing to the server.
这样能够节省服务器中数据存储的空间,同时在对第一电池的相关电池参数进行校正时不易出错,同时以上一次计费时记录的SOH为基准对第一SOH进行校正,可以减少数据运算量,有利于快速获得第二SOH。This can save data storage space in the server, and at the same time, it is less likely to make errors when correcting the relevant battery parameters of the first battery. At the same time, correcting the first SOH based on the SOH recorded during the last billing time can reduce the amount of data calculation. Conducive to quickly obtaining the second SOH.

In a possible implementation, the server can correct the first battery parameters and then send the obtained second battery parameters to the power swapping device, and the power swapping device performs billing based on the second battery parameters. In this case, the server only makes corrections and does not need to be billed.
仍然由换电设备进行计费可以避免对换电设备的大规模改动,同时又能够利用服务器中的校正模型对第一电池参数进行校正,使得换电设备能够以准确的电池参数进行计费,保证计费的准确性。Still charging by the power exchange equipment can avoid large-scale changes to the power exchange equipment. At the same time, the correction model in the server can be used to correct the first battery parameters, so that the power exchange equipment can be billed with accurate battery parameters. Ensure billing accuracy.

这样可以保证用于计费的电池参数均为已校正的电池参数,由服务器直接进行计费也有利于快速得到计费结果,降低计费时间,用户能够及时地获取到该次换电的费用,能够提高用户体验。This ensures that the battery parameters used for billing are corrected battery parameters. Direct billing by the server is also conducive to quickly obtaining billing results, reducing billing time, and users can obtain the cost of the battery replacement in a timely manner. , can improve user experience.

服务器得到计费结果后可以将计费结果直接推送给用户,或者,也可以将计费结果发送给换电设备,由换电设备推送给用户。After obtaining the billing result, the server can directly push the billing result to the user, or it can also send the billing result to the power replacement device, and the power replacement device pushes it to the user.
这样可以便于用户及时对换电过程进行付费,降低计费时间,能够提高用户体验。This can facilitate users to pay for the battery replacement process in a timely manner, reduce billing time, and improve user experience.
根据本申请的一些实施例,可选地,方法200还包括:换电设备获取第二电池的第三电池参数,第二电池为用电设备换上的电池;换电设备根据第一电池参数和第三电池参数进行计费;或者,根据第二电池参数和第三电池参数进行计费。According to some embodiments of the present application, optionally, the method 200 also includes: the power replacement device obtains the third battery parameter of the second battery, and the second battery is the battery replaced by the electrical device; the power replacement device obtains the third battery parameter of the second battery according to the first battery parameter. and third battery parameters; or, charging is performed based on the second battery parameters and the third battery parameters.
在换电过程中,换电设备需要将用电设备中已使用的旧电池换下,再为用电设备换上新电池,换下的旧电池即为第一电池,换上的新电池即为第二电池。换电设备在对第一电池的换电过程进行计费时,除了需要获取第一电池的相关电池参数,还需要获取第二电池的相关电池参数。第二电池在换上之前可以存放于换电站,与第二电池相关的电池参数可以由第二电池的BMS直接测量得到。因此,在第一电池的BMS确定需要对第一电池的第一电池参数进行校正的情况下,换电设备根据第一电池的第二电池参数与第二电池的第三电池参数进行计费;在第一电池的BMS确定不需要对第一电池的第一电池参数进行校正的情况下,换电设备根据第一电池的第一电池参数与第二电池的第三电池参数进行计费。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.
在一种可能的实施方式中,在为用电设备换上第二电池之前,也可以向第二电池发出指令,指示第二电池的BMS确定是否需要对第二电池相关的电池参数进行校正。在需要对第二电池的电池参数进行校正的情况下,第二电池的BMS向换电设备发送校正后的电池参数,则第三电池参数为校正后的电池参数;在不需要对第二电池的电池参数进行校正的情况下,第二电池的BMS直接向换电设备发送获取到的电池参数,则第三电池参数为没有经过校正的电池参数。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.
根据第一电池和第二电池的相关电池参数进行计费,可以使得计费方式更为合理,同时能够提高计费的准确性。Performing billing based on the relevant battery parameters of the first battery and the second battery can make the billing method more reasonable and improve the accuracy of billing.
根据本申请的一些实施例,可选地,换电设备可以根据以下公式(1)进行计费。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)
F=(SOC 2 ×E 2 ×SOH 2 -SOC 1 ×E 1 ×SOH 1 )×f 1 (1)
其中,F为换电费用,SOC
1和SOH
1为第一电池的第一电池参数或第二电池参数,E
1为第一电池的总电量,SOC
2和SOH
2为第二电池的第三电池参数,E
2为第 二电池的总电量,f
1为电量的单价。
Among them, F is the battery replacement cost, SOC 1 and SOH 1 are the first battery parameters or the second battery parameters of the first battery, E 1 is the total power of the first battery, SOC 2 and SOH 2 are the third battery parameters of the second battery. Battery parameters, E 2 is the total power of the second battery, and f 1 is the unit price of the power.
换电设备在对第一电池进行计费时,可以具体按照上述公式(1)进行计费。公式(1)是将第二电池的实际电量减去第一电池的实际电量,再将两者的差与电量的单价相乘,即为用户需要支付的费用。在公式(1)中,第一电池的SOC和SOH均为第一电池实际的电池参数,即在需要进行校正的情况下,SOC
1和/或SOH
1为校正后的电池参数;在不需要进行校正的情况下,可以认为BMS直接获取到的SOC
1和/或SOH
1是准确的。
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.
根据换下和换上电池的电池参数进行计费,可以充分考虑到第一电池和第二电池的电池状况,有利于准确计费。同时,在利用计费公式进行计费时,采用相应电池的实际数据进行计算,能够使得计费方式更为合理,提高计费的准确性。Charging is based on the battery parameters of the replaced and replaced batteries, which can fully take into account the battery conditions of the first battery and the second battery, which is conducive to accurate billing. At the same time, when using the billing formula for billing, the actual data of the corresponding battery is used for calculation, which can make the billing method more reasonable and improve the accuracy of billing.

在一种可能的实施方式中,同一用电设备上可以安装多个电池,则在换电过程中,换电设备还可以确定更换电池的数量,并结合更换电池的数量进行计费。举例来说,在将旧电池换下时,用电设备仅换下了一块第一电池;在为用电设备换上新电池时,用电设备要求换上多块第二电池。类似地,在将旧电池换下时,用电设备换下了多块第一电池;在为用电设备换上新电池时,用电设备仅需要换上一块第二电池。则换电设备在对换电过程进行计费时,需要考虑第一电池和第二电池数量上的差异。具体地,换电设备可以根据第一电池和第二电池的数量差来进行计费,也可以按照换上电池或换下电池的数量进行计费。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.
用电设备换上电池和换下电池的数量不同,可以根据不同需求灵活选择更换电池的数量,能够在更大范围内满足用户的需求。同时,将更换电池的数量作为换电设备计费的一个方面,也可以避免换上电池与换下电池数量不一样的情况下导致的基础费用的差异,从而可以实现合理计费,提高计费的准确性。The number of batteries to be replaced and replaced in electrical equipment is different. The number of batteries to be replaced can be flexibly selected according to different needs, which can meet the needs of users in a wider range. At the same time, considering the number of batteries replaced as an aspect of billing for battery replacement equipment can also avoid the difference in basic costs caused by replacing batteries with different numbers, thereby achieving reasonable billing and improving billing. accuracy.

在用电设备换上电池的数量和换下电池的数量不同的情况下,可以具体按照上述公式(2)进行计费。公式(2)是在公式(1)的基础上,增加了对电池的基础费用的计算。其中,f
2为一块电池的基础费用,n可以为换上电池的个数或换下电池的个数,也可以为两者之差。
