Description

Technical Field

[0001] The present invention relates to the technical field of energy storage systems, and particularly relates to a strong charging control system and a method for using the same. Background Art

[0002] Most of the household energy storage systems are operated in parallel connection to the grid. Therefore, the scenario of undervoltage rarely occurs during the application of household energy storage systems. However, in the case of power system interruption and long-term lack of sunlight, the household energy storage system may still have the situation of undervoltage. For portable energy storage systems, the application scenarios determine that the system is mostly in a situation of being disconnected from the grid. Due to people's negligence in managing the battery, the battery system may have the situation of being unable to charge due to undervoltage.

[0003] For lithium batteries in energy storage systems, the situation of long-term non-charging under undervoltage causes great damage to the battery cells. From the perspective of manufacturers, in order to extend the product life, the energy storage battery system in the case of long-term non-charging under undervoltage is designed to be unable to continue to be used. However, from the perspective of customers, customers hope to still be able to charge and continue to use under undervoltage conditions. Therefore, how to meet the customer's usage requirements while extending the service life of the energy storage battery system has become an urgent problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a strong charging control system and a method for using the same, which can meet the customer's usage requirements while extending the service life of the energy storage battery system.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0014] S3. Provide the input count of the strong charge wake-up signal to the manufacturer to facilitate the manufacturer's restriction on the user's use of the strong charge wake-up of the energy storage battery.

[0015] The beneficial effects of the present invention are as follows: A strong charge control system and its usage method are provided. A manual wake-up device is introduced between the battery management system and the power supply. A strong charge wake-up signal is generated through manual operation, thereby allowing the energy storage battery to be strongly charged under undervoltage conditions.

[0021] To describe in detail the technical content, achieved objectives, and effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0022] Please refer to Figure 1 , a strong charge control system includes a battery management system 1, a power supply 2, and a manual wake-up device 3;

[0023] The power supply output terminal of the power supply 2 is respectively connected to the power supply input terminal of the battery management system 1 and the power supply terminal of the manual wake-up device 3;

[0024] The signal output end of the manual wake-up device 3 is connected to the strong charge wake-up signal input end of the battery management system 1;

[0025] The battery management system 1 is used to record the input times of the strong charge wake-up signal.

[0026] As can be seen from the above description, the beneficial effect of the present invention is that a manual wake-up device 3 is introduced between the battery management system 1 and the power supply 2, and a strong charge wake-up signal is generated through manual operation, so as to allow the energy storage battery 7 to be used for strong charging under the under-voltage condition. By recording and feeding back the input times of the strong charge wake-up signal to the manufacturer, the use of the strong charge wake-up by users is restricted, effectively preventing the premature termination of the service life of the energy storage battery 7, and at the same time avoiding the trouble that the customer cannot continue to use due to his own negligence, meeting the actual use needs of the customer.

[0027] Further, the manual wake-up device 3 is a key switch.

[0028] As can be seen from the above description, the manual wake-up device 3 is a key switch, and the user needs to insert or pull out the key to achieve manual wake-up or stop using, which can effectively prevent others from misusing the strong charge wake-up function, with high safety and simple and convenient operation.

[0029] Further, a strong charge indication device 4 is also included;

[0030] The strong charge indication device 4 is electrically connected to the battery management system 1.

[0031] As can be seen from the above description, a strong charge indication device 4 is set in the system, so as to be able to remind the user that the current is in the state of using strong charge wake-up, which has a warning effect on the user.

[0032] Further, the strong charge indication device 4 is a signal indicator light.

[0033] As can be seen from the above description, using the signal indicator light as the strong charge wake-up indication has a striking and significant indication effect, and can also improve the effect by using different lamp colors or flashing displays, etc., and is flexible and convenient to use.

[0034] Further, a remote communication module 5 is also included;

[0035] The remote communication module 5 is connected to the battery management system 1 and is used for wireless communication with the manufacturer platform 8.

[0036] As can be seen from the above description, a remote communication module 5 is set on the system, so that the battery management system 1 can communicate with the manufacturer platform 8 remotely, helping the manufacturer platform 8 to understand the use situation of the energy storage battery 7 in real time and facilitating its maintenance.

[0037] Please refer toFigure 2 and Figure 3 A method of using a strong charging control system, which is applied to the above-mentioned strong charging control system, includes the following steps:

[0038] S1. When the energy storage battery 7 is in an under-voltage state, determine whether a strong charging wake-up signal sent by the manual wake-up device 3 is received. If so, execute step S2;

[0039] S2. Charge the energy storage battery 7 using a preset charging strategy and record that the input count of the strong charging wake-up signal is incremented by 1;

[0040] S3. Provide the manufacturer with the input count of the strong charging wake-up signal, so that the manufacturer can restrict the user's use of the strong charging wake-up of the energy storage battery 7.

[0041] As can be seen from the above description, the beneficial effects of the present invention are as follows: A manual wake-up device 3 is introduced between the battery management system 1 and the power supply 2, and a strong charging wake-up signal is generated through manual operation, thereby allowing the energy storage battery 7 to be strongly charged under under-voltage conditions. By recording and feeding back the input count of the strong charging wake-up signal to the manufacturer to restrict the user's strong charging wake-up use, it effectively prevents the premature termination of the service life of the energy storage battery 7, and at the same time avoids the trouble that the customer cannot continue to use due to his own negligence, meeting the actual use needs of the customer.

[0042] Further, the preset charging strategy is:

[0043] Charge the energy storage battery 7 using a preset safe current;

[0044] Judge whether the real-time SOC value of the energy storage battery 7 reaches a preset SOC value. If so, switch to charging the energy storage battery 7 using a normal charging current.

[0045] As can be seen from the above description, when starting to charge under under-voltage, a preset safe current is used for charging, and when the SOC value of the battery reaches the preset SOC value, it is switched to charging with a normal charging current, thereby ensuring that the battery is in a safe use state and reducing damage to the battery cells.

[0046] Further, when charging the energy storage battery 7 using the preset safe current, it also includes:

[0047] Control the signal indicator to display red;

[0048] When charging the energy storage battery 7 using the normal charging current, it also includes:

[0049] Control the signal indicator to display green.

[0050] As can be seen from the above description, different lamp colors are used for prompting according to different charging currents, so as to enable users to understand the charging status of the energy storage battery 7 in real time, and then use it reasonably to improve the safety of use.

[0051] Further, the specific number of times of inputting the strong charge wake-up signal to the manufacturer is as follows:

[0052] Judge whether the number of times of inputting the strong charge wake-up signal reaches the preset number of times. If so, report the number of times of inputting the strong charge wake-up signal to the manufacturer platform 8 through the remote communication module 5.

[0053] As can be seen from the above description, the battery management system 1 can communicate remotely with the manufacturer platform 8 to help the manufacturer platform 8 understand the usage situation of the energy storage battery 7 in real time, which is convenient for its maintenance.

[0054] Further, the preset SOC value is 4%-6%.

[0055] As can be seen from the above description, the preset SOC value is reasonably set to ensure that the energy storage battery 7 can be charged with a normal charging current under safe conditions.

[0056] A strong charge control system and its usage method of the present invention can be applied to the scenario of using the energy storage battery 7, which will be described below through specific embodiments:

[0057] Please refer to Figure 1 , the first embodiment of the present invention is:

[0058] A strong charge control system, as Figure 1 shown, includes a battery management system 1, a power supply 2, a remote communication module 5 and a manual wake-up device 3. The power supply output end of the power supply 2 is respectively connected to the power supply input end of the battery management system 1 and the power supply end of the manual wake-up device 3. The signal output end of the manual wake-up device 3 is connected to the strong charge wake-up signal input end of the battery management system 1. The battery management system 1 is used to record the number of times of inputting the strong charge wake-up signal. The remote communication module 5 is connected to the battery management system 1 and is used for wireless communication with the manufacturer platform 8.

[0059] In this embodiment, the battery management system 1 (BMS) is commonly known as a battery nanny or battery butler, mainly for intelligently managing and maintaining each battery unit, preventing the battery from overcharging and over-discharging, extending the service life of the battery, and monitoring the battery status. The system is powered by an external energy storage PCS 6. As Figure 1 shown, under normal circumstances, the battery management system 1 is woken up and started by a key wake-up to wake itself up and start high-voltage connection for charge and discharge control.

[0060] In this embodiment, the manual wake-up device 3 can be selected as a key switch, and a strong charge wake-up signal is sent to the battery management system 1 by inserting a key; when the key is pulled out, the strong charge wake-up signal becomes invalid accordingly. In other equivalent embodiments, other forms of manual switches such as gesture recognition switches can also be used.

[0061] In this embodiment, as Figure 1 shown, the battery management system 1 is also connected to a strong charge indication device 4. The strong charge indication device 4 is preferably a signal indicator light. In other equivalent embodiments, the strong charge indication device 4 can also use other physical indication devices such as a buzzer.

[0062] Please refer to Figure 2 and Figure 3 , the second embodiment of the present invention is:

[0063] A usage method of a strong charge control system, applied to a strong charge control system in the first embodiment, includes the following steps:

[0064] S1. When the energy storage battery 7 is in an undervoltage state, determine whether a strong charge wake-up signal sent by the manual wake-up device 3 is received. If so, execute step S2;

[0065] S2. Charge the energy storage battery 7 using a preset charging strategy and record that the input times of the strong charge wake-up signal are incremented by 1;

[0066] In this embodiment, as Figure 3 shown, the preset charging strategy is:

[0067] Charge the energy storage battery 7 using a preset safe current;

[0068] Judge whether the real-time SOC value of the energy storage battery 7 reaches the preset SOC value. If so, switch to charging the energy storage battery 7 using a normal charging current. Among them, the value range of the preset SOC value is 4% - 6%, preferably 5%. The preset safe current is a very small charging current limited, and its maximum value is 0.1c.

[0069] Moreover, when charging the energy storage battery 7 using the preset safe current, it also includes: controlling the signal indicator light to display red to remind the user that the current is in the forced charging mode; when charging the energy storage battery 7 using the normal charging current, it also includes: controlling the signal indicator light to display green to remind the user that the current is in the normal charging mode.

[0070] In this embodiment, the user sends a strong charge wake-up signal to the battery management system 1 by inserting a key at the key switch, and when the charging stage of charging the energy storage battery 7 using the preset safe current is completed, the user needs to pull out the key to be able to switch to charging with the normal charging current.

[0071] S3. Provide the input times of the strong charge wake-up signal to the manufacturer, so as to facilitate the manufacturer to restrict the user's use of strong charge wake-up for the energy storage battery 7.

[0072] In this embodiment, the specific method of providing the input times of the strong charge wake-up signal to the manufacturer is as follows:

[0073] Judge whether the input times of the strong charge wake-up signal reach the preset times. If so, report the input times of the strong charge wake-up signal to the manufacturer platform 8 through the remote communication module 5.

[0074] In this embodiment, the manufacturer can discover the user's strong charge usage behavior through the manufacturer platform 8; if the times are too many, the user's usage method can be trained to prevent the energy storage battery 7 from reaching the end of its life prematurely. Among them, the preset times can be selected from 9 to 11 times, preferably 10 times.

[0075] In summary, a strong charge control system and its usage method provided by the present invention introduce a manual wake-up device between the battery management system and the power supply. A strong charge wake-up signal is generated through manual operation, so as to allow the energy storage battery to be strongly charged under the under-voltage condition. The signal indicator lamp is used to indicate the charging state of the energy storage battery. By recording and remotely feeding back the input times of the strong charge wake-up signal to the manufacturer, the user's strong charge wake-up usage is restricted, effectively preventing the premature termination of the service life of the energy storage battery. At the same time, it also avoids the trouble that the customer cannot continue to use due to his own negligence, meeting the actual usage needs of the customer.

[0076] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent transformation made by using the specification and drawings of the present invention, or directly or indirectly applied in the related technical fields, shall be equally included in the patent protection scope of the present invention.
