[0035] With the rapid development of social economy, energy consumption is increasing. With the development and utilization of renewable energy, solar photovoltaic power generation has become one of the hot technologies in the world. In the field of solar photovoltaic power generation, tracking brackets can greatly improve the power generation efficiency of solar panels. Usually, the tracking bracket system includes two control parts: network controller and motor controller. Among them, the motor controller contains a large-capacity battery, which is used to power the motor controller from the inside when there is no external power input at night, so as to maintain communication and motor drive operation.

[0036] Since the construction cycle of the photovoltaic industry is generally long, it takes a long time for the motor controller to be delivered and put into operation from the completion of factory production to the project site. The batteries required inside the motor controller will be damaged if they are stored for a long time after production. In order to avoid this damage, a battery maintenance method is needed to perform regular maintenance on the battery to maintain the battery life.

[0037] See attached Figure 1 , Figure 1 FIG. 1 is a flow chart of the main steps of a battery maintenance method according to an embodiment of the present application. Figure 1 As shown, the battery maintenance method in the embodiment of the present application mainly includes the following steps S101 to S103:

[0038] Step S101, collecting the remaining power of multiple batteries from any batch of batteries.

[0039] In this embodiment, any batch of batteries refers to batteries produced in the same batch with the same model and parameters. The remaining power of multiple batteries is collected, for example, multiple batteries are sampled from the batteries produced in the same batch at a sampling rate of x%, and the remaining power of the multiple batteries is calculated.

[0040] In one implementation, assuming that a batch of batteries produced by a factory has a total of 600 batteries, 6 batteries are sampled from the 600 batteries at a sampling rate of 1%, and the remaining power of the 6 batteries is calculated.

[0041] In one implementation, the remaining capacity of the battery may be calculated by a discharge test, ampere-hour integration, or the like.

[0042] Step S102, calculating an average remaining power according to the remaining power of the multiple batteries.

[0043] In this embodiment, in order to ensure the accuracy of the remaining power calculation, the remaining power of multiple sampled batteries is averaged, and the average remaining power is calculated to represent the remaining power of this batch of batteries.

[0044] Step S103: when the ratio of the average remaining power to the nominal capacity of the batch of batteries is less than or equal to a first threshold, the batch of batteries is charged.

[0045] In this embodiment, the ratio of the average remaining power in step S102 to the nominal capacity of the batch of batteries is compared with the first threshold value to determine whether the batch of batteries needs charging maintenance.

[0046] In one implementation, the first threshold may be set according to actual conditions. As an example, the first threshold is 85%. When the average remaining power / nominal capacity is ≤ 85%, all batteries in the batch are charged.

[0047] Based on the method described in steps S101 to S103 above, by collecting the remaining power of multiple batteries in any batch and calculating the average remaining power, when the ratio of the average remaining power to the nominal capacity is less than or equal to the first threshold, the batch of batteries is charged. The purpose of automatically charging the batteries according to the remaining power during storage is achieved, and the effect of maintaining the battery capacity and extending the battery life is achieved, which is conducive to eliminating the uncomplicated sulfation phenomenon of the battery after discharge, restoring the active substances in the battery, and solving the problem of performance degradation caused by long-term storage of the battery.

[0048] In an optional embodiment, the method further includes:

[0049] Step S104, calculating the next battery maintenance cycle according to the average remaining power, the nominal capacity and the preset battery maintenance cycle.

[0050] Usually, the battery does not need to be maintained immediately after production, and can be maintained 150-210 days (preset maintenance period) after production at the factory. As an example, the countdown is 180 days after the battery is produced, and after the countdown ends, the battery is maintained according to the above steps S101 to S103.

[0051] In this embodiment, after the preset maintenance is completed, the following formula can be used to calculate the next battery maintenance cycle:

[0052] Among them, the average remaining power is the average remaining power of multiple sampled batteries calculated for this maintenance, and details can be referred to step S102; the nominal capacity is the capacity marked on the battery, generally expressed in units of Ah (ampere-hour) or mAh (milliampere-hour), which can be regarded as the theoretical maximum capacity of the battery, indicating the capacity of the battery under specified conditions; the preset battery maintenance cycle is a pre-determined maintenance cycle, such as 180 days.

[0053] Step S105, at the end of the next battery maintenance cycle, re-execute the steps of collecting the remaining power of multiple batteries from any batch of batteries, calculating the average remaining power, charging the batch of batteries when the ratio of the average remaining power to the nominal capacity is less than or equal to the first threshold, and calculating the next battery maintenance cycle.

[0054] In this embodiment, when the next battery maintenance cycle calculated in step S104 ends, steps S103 to S104 are re-executed, thereby achieving the purpose of regularly maintaining the battery according to the battery status and achieving the effect of improving the reliability of battery maintenance.

[0055] In an optional implementation, when the next battery maintenance cycle is less than a preset battery maintenance cycle, a first warning message is sent.

[0056] In this embodiment, the battery status is monitored with the help of the battery maintenance cycle, and the first warning information is sent when the battery status is less than the preset battery maintenance cycle, thereby achieving the purpose of timely monitoring the performance of the battery during storage.

[0057] In one implementation, when the next battery maintenance cycle is less than 180 days, a first warning message is sent to indicate that the battery power of this batch is decaying too quickly, there may be a quality risk, and further analysis is required by staff.

[0058] In an optional implementation, the above step S102 may further include:

[0059] Step S1021 , discharging any sampled battery with a preset discharge current to obtain an actual discharge time.

[0060] In this embodiment, the actual discharge time corresponding to the sampling battery is obtained by discharging the sampling battery, wherein the size of the preset discharge current can be set according to specific needs, and this embodiment does not impose any specific limitation on this.

[0061] Step S1022, calculating the remaining power of any sampled battery according to the product of the preset discharge current and the actual discharge time.

[0062] In this embodiment, the remaining capacity of any sampled battery is calculated according to the product of the preset discharge current and the actual discharge time in step S1021.

[0063] Step S1023, calculating an average remaining power according to an average value of the remaining power of the plurality of sampled batteries.

[0064] In this embodiment, the remaining power of all sampled batteries is averaged, and the obtained average remaining power represents the remaining power of the batch of batteries.

[0065] In an optional embodiment, the method further includes:

[0066] Step S105, obtaining the theoretical discharge time of the battery.

[0067] In this embodiment, the theoretical discharge time is similar to the nominal capacity, which is the time the battery takes to discharge theoretically and can be obtained from the information of the battery produced by the factory. Due to factors such as the internal resistance of the battery and the ambient temperature, there is a certain deviation from the actual discharge time.

[0068] Step S106, calculating the life of any sampled battery according to the theoretical discharge time and the actual discharge time.

[0069] In this embodiment, the life of any sampled battery is calculated using the following formula:

[0070] Step S107 , calculating an average life of the sampled battery according to an average value of the lifespans of the plurality of sampled batteries.

[0071] In this embodiment, an average value of a plurality of sampled battery lifespans is calculated as the average battery lifespan.

[0072] Step S108: When the average life of the sampled battery is less than a second threshold, a second warning message is sent.

[0073] In this embodiment, the average life of the battery is monitored, and when the average life is less than a second threshold, a second warning message is sent.

[0074] In one implementation, the second threshold may be set according to specific requirements. As an example, the second threshold may be set to 80%.

[0075] This embodiment achieves the purpose of regular maintenance of the battery, achieves the effect of maintaining the battery capacity and extending the battery life, and solves the problem of performance degradation caused by long-term storage of the battery.

[0076] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders. These adjusted schemes are equivalent to the technical schemes described in this application, and therefore will also fall within the scope of protection of this application.

[0077] Existing active battery balancing technology is usually unable to measure the current battery power, and it is difficult to perform accurate charging operations. In response to the above problem, another aspect of the present application further provides a battery maintenance device, including: a remaining power acquisition module 201, used to collect the remaining power of multiple batteries from any batch of batteries; an average remaining power calculation module 202, used to calculate the average remaining power based on the remaining power of the multiple batteries; a charging maintenance module 203, used to charge the batch of batteries when the ratio of the average remaining power to the nominal capacity of the batch of batteries is less than or equal to a first threshold.

[0079] In one technical solution of the above battery maintenance device, the following formula is used to calculate the next battery maintenance cycle:

[0080] In a technical solution of the above-mentioned battery maintenance device, it also includes: a first warning module, which is used to send a first warning message when the next battery maintenance cycle is less than a preset battery maintenance cycle.

[0081] In a technical solution of the above-mentioned battery maintenance device, the average remaining power calculation module includes: a discharge unit, which is used to discharge any sampled battery with a preset discharge current to obtain an actual discharge time; a remaining power calculation unit, which is used to calculate the remaining power of any sampled battery based on the product of the preset discharge current and the actual discharge time; and an average remaining power calculation unit, which is used to calculate the average remaining power based on the average value of the remaining power of multiple sampled batteries.

[0082] In a technical solution of the above-mentioned battery maintenance device, it also includes: an acquisition module, used to obtain the theoretical discharge time of the battery; a life calculation module, used to calculate the life of any sampled battery based on the theoretical discharge time and the actual discharge time; an average life calculation module, used to calculate the average life of the sampled battery based on the average value of the lifespans of multiple sampled batteries; a second warning module, used to send a second warning message when the average lifespan of the sampled battery is less than a second threshold.

[0083] In one technical solution of the above battery maintenance device, the following formula is used to calculate the life of any sampled battery:

[0084] In an optional embodiment, a battery maintenance device (equipment) can be used in a production plant and has networking capabilities. It can communicate with the factory server to obtain production battery information; automatically measure battery life; and automatically record the storage time of the battery after production, so that the battery can be maintained when the specified time arrives.

[0085] Figure 3 is a schematic diagram of a battery maintenance device according to an embodiment of the present application, such as Figure 3 As shown, the battery maintenance device includes multiple discharge ports, multiple charging ports, a switch and a power supply. Among them, the multiple discharge ports are used to perform discharge tests on sampled batteries and calculate the remaining power and life of the batteries; the multiple charging ports are used to perform charging maintenance on the batteries; the switch is used to control the battery maintenance device to be turned on and off; and the power supply is used to power the battery maintenance device.

[0086] In an example of an application scenario of this application, suppose a factory produces a batch of batteries, which need to be stored for a period of time before being transported to the project site. At this time, the above-mentioned battery maintenance device can be used to perform regular maintenance on the batch of batteries. The specific steps are as follows:

[0087] Step S1, after the factory completes the battery assembly, the factory server sends the battery assembly completion time and battery information (such as the battery's nominal capacity, battery cell type, maximum monthly battery power loss value, etc.) to the battery maintenance device, and the battery maintenance device starts timing according to the battery assembly completion time, such as a countdown of 180 days.

[0088] Step S2, after the timing ends, the sampling battery is connected to a plurality of discharge ports of the battery maintenance device, and the battery maintenance device starts discharging the sampling battery.

[0089] Step S3: After the discharge is completed, the battery maintenance device calculates the average remaining power and average life of the sampled battery. The detailed calculation steps can be found in other embodiments of the present application and will not be repeated here.

[0090] In step S4, the battery maintenance device calculates the next maintenance time, that is, the next battery maintenance cycle, based on the average remaining power and average life in step S3, and analyzes the battery risks. If the next maintenance time is less than 180 days, a first warning message is issued, indicating that the battery power of this batch is decaying too quickly, there is a quality risk, and further analysis is required by staff.

[0091] Step S5: if the average remaining power / nominal capacity is ≤ the first threshold value (eg, 85%), all batteries in the batch are charged, that is, the batteries are connected to the charging port of the battery maintenance device to start charging.

[0092] In an optional implementation, a battery maintenance device may also be arranged at the project site, and communicate with the factory server to obtain battery information (including battery production information, historical maintenance information, etc.). After the above step S5, the method further includes:

[0093] Step S6, after the factory ships the batteries to the project site, the factory server sends the battery information, such as battery number, arrival date, average life of the batch of batteries, historical maintenance date, etc., to the battery maintenance device at the project site.

[0094] Step S7, after receiving the above information, the battery maintenance equipment at the project site synchronizes the last maintenance time of the batch of batteries and restarts the timing. The subsequent steps are the same as S2 to S5.

[0095] This embodiment achieves the purpose of performing regular maintenance on the battery to maintain the battery life when the battery is stored for a long time. By deploying battery maintenance equipment in multiple locations and synchronizing information with the factory server, the battery can still be maintained after it is shipped from the factory.
