Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage batteries, more particularly to a full-factor monitoring remote capacity checking system for storage batteries. BACKGROUND

[0002] Storage battery capacity checking can ensure the performance of storage batteries and prolong their service life. Through capacity checking, abnormal conditions of storage batteries, such as capacity reduction and internal resistance increase, can be found and handled in time, which may cause storage batteries to fail to work normally at critical moments. In addition, regular capacity checking can help users understand the actual capacity of storage batteries, so as to replace or maintain them when necessary. In general, storage battery capacity checking is an important measure to ensure the stable operation of power systems and improve energy utilization efficiency.

[0003] However, the existing storage battery capacity checking method is mostly to disconnect the storage battery and the power supply, and then let the storage battery discharge alone to a dummy load. The electric energy is mostly consumed in the form of heat energy during the capacity checking process of the dummy load, which cannot effectively utilize the electric energy of the storage battery and causes energy waste. Therefore, how to utilize the electric energy during storage battery capacity checking is the technical problem to be solved by the present application. SUMMARY

[0004] In view of the deficiencies in the prior art, the present application provides a full-factor monitoring remote capacity checking system for storage batteries, which can remotely control the voltage increase of storage batteries for capacity checking, so that the storage batteries directly discharge to a load during capacity checking.

[0005] The present application provides a full-factor monitoring remote capacity checking system for storage batteries, and the technical solution is as follows:

[0006] A full-factor monitoring remote capacity checking system for storage batteries comprises a capacity checking device, which is connected with a storage battery, a capacity checking circuit and a monitoring unit host. The capacity checking circuit and the monitoring unit host are connected with the storage battery. The capacity checking device is powered by an external power supply. The external power supply and the storage battery are connected with a load.

[0007] When the storage battery is checked for capacity, the capacity checking device controls the voltage increase of the storage battery to be greater than that of the external power supply through the capacity checking circuit, so that the storage battery supplies power to the load.

[0008] When the monitoring unit host determines that the capacity checking of the storage battery is completed, the load is supplied with power by the external power supply, and the storage battery is controlled to be charged evenly.

[0009] When the monitoring unit host determines that the charging of the storage battery is completed, the storage battery is controlled to be charged in a floating manner.

[0010] The monitoring unit host is used to collect the voltage, current and temperature information of the storage battery in real time, and display them on the capacity checking device.

[0011] In summary, the beneficial effects of the present application include: the battery capacity of the present application is through the DC / DC boost mode of the capacity system, so that the battery capacity can supply power to the load effectively, and the discharge process does not generate heat. During the discharge process, the battery voltage is greater than the external power supply voltage, and when the external power supply stops, the battery always outputs to the load, without the risk of offline. The capacity system of the present application is easy to install and maintain, and the cost is moderate. BRIEF DESCRIPTION OF DRAWINGS

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0021] As Figure 1As shown, a full-factor monitoring battery 20 remote capacity system includes a capacity device 10, the capacity device 10 is connected with the battery 20, a capacity circuit 30 and a monitoring unit host 40 respectively, the capacity circuit 30 and the monitoring unit host 40 are connected with the battery 20 respectively, the capacity device 10 is powered by an external power supply, the external power supply and the battery 20 are connected with a load respectively; when the battery 20 is capacity, the capacity device 10 controls the battery 20 to boost the voltage greater than the external power supply through the capacity circuit 30, so as to supply the load by the battery 20; when the battery 20 is judged to be capacity completed by the monitoring unit host 40, the load is supplied by the external power supply, and the battery 20 is controlled to be equal charged; when the battery 20 is judged to be equal charged completed by the monitoring unit host 40, the battery 20 is controlled to be float charged; the monitoring unit host 40 is used for collecting the voltage, current and temperature information of the battery 20 in real time, and displaying on the capacity device 10.

[0022] The battery 20 capacity of the application is through the capacity system to adopt DC / DC boost mode, so that the battery 20 capacity can supply the load effectively, and the discharging process does not heat. In the discharging process, the battery 20 voltage is greater than the external power supply voltage, and when the external power supply stops, the battery 20 always outputs to the load, without offline risk. The capacity system of the application is easy to install and maintain, and the cost is moderate.

[0023] As shown, Figures 2-4 The capacity circuit 30 includes a boost module 31, a pre-charging module 32, a contactor K1 and a contactor K2, the capacity device 10 is connected with the signal end of the boost module 31, the pre-charging module 32, the contactor K1 and the contactor K2 respectively; the positive end of the capacity device 10 is connected to the output end of the boost module 31 and the positive pole of the battery 20, one side of the input end of the boost module 31 is connected with the positive pole of the battery pack, and the other side of the input end is connected with the negative pole of the battery pack through the contactor K1, and the negative end of the capacity device 10 is connected with the negative pole of the battery 20; one side of the charging end of the pre-charging module 32 is connected with the positive pole of the battery 20, and the other side of the charging end is connected with the negative pole of the battery 20 through the contactor K2; as shown, Figure 2 When the battery 20 is capacity, the capacity device 10 controls the contactor K1 switch to close, so that the boost module 31 is connected, controls the contactor K2 switch to open, so that the pre-charging module 32 is disconnected, and the boost module 31 controls the battery 20 to boost the voltage greater than the external power supply, so as to supply the load by the battery 20; as shown, Figure 3 When the battery 20 is judged to be capacity completed by the monitoring unit host 40, the capacity device 10 controls the contactor K1 switch to open, so that the boost module 31 is disconnected, controls the contactor K2 switch to close, so that the pre-charging module 32 is connected, so as to equal charge the battery 20 by the charging module; as shown, Figure 4As shown, when the monitoring unit host 40 judges that the battery 20 is fully charged, the contactor K2 switch is controlled to be turned off by the capacity maintenance device 10, so that the pre-charging module 32 is turned off and the battery 20 is floated.

[0024] Specifically, when the battery 20 is fully charged, the contactor K1 switch is also turned off, so that the voltage boosting module 31 is turned off. Because the capacity maintenance time is shorter than the floating charging time, the contactor K1 and the contactor K2 are preferably normally open contactors. The remote capacity maintenance system uses an isolated voltage boosting technology to make the capacity maintenance control safer. Through the intelligent charging and discharging management function, the battery 20 can be remotely discharged and maintained. The capacity maintenance device 10 establishes remote communication with the voltage boosting module 31, the pre-charging module 32 and the monitoring unit host 40 through the RS485 network interface or other communication network interfaces. The capacity maintenance device 10 is used to collect the working state of the capacity maintenance circuit 30 and is indicated by indicator lights. The meanings of the running indicator lights are as follows: the host working light, the running light is on in any working state, indicating that the host is running. The meaning of the online floating charging indicator light is as follows: the indicator light is on, indicating that the host is in the "online floating charging state". The meaning of the capacity maintenance test indicator light is as follows: the capacity maintenance test state indication, the light is on, indicating that the host is in the capacity maintenance test state. The meaning of the KD test indicator light is as follows: the KD test state indication, the light is on, indicating that the host is in the KD test state. The meaning of the internal resistance test indicator light is as follows: the internal resistance test state indication, the light is on, indicating that the host is in the internal resistance test state. The meaning of the power failure discharge indicator light is as follows: the power failure discharge state indication, the light is on, indicating that the host room is powered off, and the battery 20 is supplying power to the outside through the equipment.

[0025] The capacity maintenance circuit 30 further comprises a voltage reducing module 33, a contactor K0 and a freewheeling diode. The capacity maintenance device 10 is connected to the signal end of the contactor K0. The positive end of the capacity maintenance device 10 is connected to one end of the contactor K0 and the negative end of the freewheeling diode. The other end of the contactor K0 is connected to the positive end of the battery 20. The positive end of the freewheeling diode is connected to the positive end of the battery 20 through the voltage reducing module 33. When the monitoring unit host 40 judges that the battery 20 is fully charged, the pre-charging module 32 fully charges the battery 20. The capacity maintenance device 10 controls the contactor K0 switch to be turned off, so that the voltage reducing module 33 is turned on. The voltage reducing module 33 controls the voltage between the battery 20 and the load to be less than the voltage of the external power supply, thereby avoiding the interference of the load on the full charging of the battery 20.

[0026] The positive end and the negative end of the capacity maintenance device 10 are connected to an external rectifier. The external rectifier is used to rectify the external alternating current into direct current to supply power to the load or to float charge the battery 20.

[0027] The battery 20 is under the action of the voltage reduction module 33 on the on-line capacity device 10: if there is no voltage reduction module 33, the battery 20 is discharged, the pre-charging module 32 starts to uniformly charge the battery 20, and as the charging process, the charging voltage curve is from low to high, and the highest uniform charging voltage reaches 56.3V, at this time, the voltage of the capacity circuit 30 is higher than the normal voltage of 54V of the external power supply (rectifier), and a voltage difference is generated between the capacity circuit 30 and the external power supply bus, the freewheeling diode on the capacity circuit 30 is turned on, and the load on the external power supply is transferred to the capacity circuit 30, so the pre-charging module 32 will bear the entire load on the external power supply in addition to the charging load of the battery 20, therefore, the voltage reduction module 33 is added in the design, the voltage reduction module 33 adjusts the voltage generated by the battery 20 to 52V, which is less than the voltage of the external power supply, so that the voltage of 54V of the external power supply is always higher than the voltage between the battery 20 and the load during the uniform charging of the battery 20, avoiding the discharge of the battery 20 during the uniform charging, and ensuring the normal uniform charging of the capacity circuit 30.

[0028] Preferably, when the battery 20 is uniformly charged, the capacity device 10 controls the contactor K0 switch to be opened, so that the external power supply and the voltage reduction module 33 are turned on; in this way, when the battery 20 is uniformly charged, the voltage rises and is greater than the external power supply, and after being reduced by the voltage reduction module 33, it is less than the voltage of the external power supply, so that the battery 20 is not affected by the external power supply and the load during the uniform charging. When the battery 20 is fully charged by the monitoring unit host 40, the capacity device 10 controls the contactor K0 switch to be closed, so that the voltage reduction module 33 is short-circuited, and the external power supply is turned on through the contactor K0 to float charge the battery 20.

[0029] The capacity circuit 30 also includes a dummy load, the dummy load is connected in parallel to both ends of the battery 20 through the contactor K3, and the capacity device 10 is connected with the signal end of the contactor K3; when the dummy load is needed for capacity, the contactor K3 is controlled to be closed, so that the battery 20 is discharged through the dummy load for capacity.

[0030] If the actual load of the load connected to the external power supply is small, the battery pack cannot be 0.1C10 (0.1A current discharge for 10 hours) for capacity through the DC / DC voltage reduction module 33, therefore, by increasing the dummy load, the DC / DC voltage reduction module 33 or the dummy load can be selected for capacity according to the capacity demand. The capacity circuit 30 also includes a fan, the fan is connected in parallel to both ends of the battery 20 through the contactor K4, and the capacity device 10 is connected with the signal end of the contactor K4; when the battery 20 is discharged for capacity through the dummy load, and the capacity device 10 judges that the temperature of the battery 20 exceeds the preset temperature through the monitoring unit host 40, the contactor K4 is controlled to be closed, so that the fan is turned on to dissipate heat.

[0031] When the capacity is performed through the dummy load, heat is generated, and the design of the fan can avoid the influence of the heat dissipation of the dummy load on the battery 20.

[0032] The core capacity device 10 stores the historical battery 20 core capacity information, so as to view the historical information change of the battery 20, when the battery 20 is floating charged, the core capacity device 10 can monitor the internal resistance of the battery 20 through the monitoring unit host 40, so as to judge the health condition of the battery 20 according to the internal resistance of the battery 20 and the voltage change of the battery 20 each time.

[0033] The main station of the core capacity device 10 adopts B / S architecture, has an alarm expert module, can multi-angle analyze the battery data, can support short message (optional), sound alarm prompt function; has powerful data recording function, can view historical data at any time, has friendly man-machine interface, can automatically form analysis chart and rich report according to the collected data, so as to more directly view the health condition of the battery 20.

[0034] As shown in Figure 5 The monitoring unit host 40 includes a main control module, a main switch ZY, a discharge switch FD and a charging switch CD, the main switch ZY, the discharge switch FD and the charging switch CD are respectively used for controlling the contactor K0, the contactor K1 and the relay K2.

[0035] The main control module is connected with the control end of the main switch, the discharge switch and the charging switch respectively; the first normally open output end of the main switch is connected to the first input end of the discharge switch, the second normally open output end is connected to the control end of the contactor K0, used for controlling the on-off of the contactor K0, the third normally open output end is connected to the first input end of the charging switch; the first normally closed output end of the discharge switch is connected to the control end of the charging switch, the second normally open output end is connected to the control end of the contactor K1, used for controlling the on-off of the contactor K1; the first normally closed output end of the charging switch is connected to the control end of the discharge switch, used for interlocking with the discharge switch, the second normally open output end is connected to the control end of the contactor K2, used for controlling the on-off of the contactor K2.

[0036] When the control end of the main switch is attracted, the normally closed contactor K0 is disconnected. The main control module controls the control end of one of the charging switch and the discharging switch to be powered, because one line of the control end of the charging switch and the discharging switch is controlled by the first normally closed output end of the other, so that the control end of the discharging switch and the control end of the charging switch are attracted and the other is not attracted, thereby realizing the interlocking relationship that one of the contactor K1 and the contactor K2 is powered and the other is not powered. When the control end of the main switch is disconnected, the charging switch and the discharging switch cannot be powered. In the figure, the main switch, the discharging switch, the charging switch and the standby switch are all four-blade double-throw intermediate relays, the ninth pin on the left side is the first input end, the tenth pin is the second input end, the eleventh pin is the third input end, the twelfth pin is the fourth input end, the first pin on the right side is the first normally closed output end, the fifth pin is the first normally open output end, the second pin is the second normally closed output end, the sixth pin is the second normally open output end, the third pin is the third normally closed output end, the seventh pin is the third normally open output end, the fourth pin is the fourth normally closed output end, and the eighth pin is the fourth normally open output end. The thirteenth pin and the fourteenth pin on the left side are used as control ends.

[0037] The contactor K0 is a normally closed contactor, and the contactors K1 and K2 are normally open contactors.

[0038] In this way, when the normally closed contactor K0 is not powered, the normally open contactors K1 and K2 cannot be powered and closed, and the nuclear capacity system is in a floating charging state. When the nuclear capacity is to be realized, the normally closed contactor K0 is powered and disconnected, and then the normally open contactor K1 can be controlled to be closed, so that the boost module 31 is powered to realize the nuclear capacity discharge. At this time, the normally open contactor K2 cannot be powered and closed due to the interlocking, and the pre-charging module 32 cannot be operated. When the nuclear capacity is completed, the normally open contactor K1 can be controlled to be powered and opened, so that the boost of the boost module 31 is ended. Then the normally open contactor K2 can be controlled to be powered and closed, so that the pre-charging module 32 is powered to operate, thereby realizing the equal charging of the storage battery 20. Thus, the device control is more intelligent and safe.

[0039] The monitoring unit host 40 further comprises a standby switch BY, and the control ends of the main control module and the standby switch are connected. The fourth normally open output end of the main switch is connected to the third input end of the discharging switch, the third normally closed output end of the discharging switch is connected to the third input end of the charging switch, the third normally closed output end of the charging switch is connected to the control end of the standby switch, and the second normally closed output end of the standby switch is connected to the control end of the contactor K3. When the coil of the main switch is closed and the coils of the discharging switch and the charging switch are not closed, the coil of the contactor K3 can be controlled to be closed.

[0040] The contactor K3 is a normally open contactor. Through the above-mentioned circuit design, when the normally closed contactor K0 is not powered, the normally open contactor K3 cannot be powered to be closed, and the nuclear storage system is in a floating charge state. When the false load needs to be used for nuclear storage, the normally closed contactor K0 is powered off, and then the normally open contactor K3 can be controlled to be closed, so that the false load and the battery 20 are turned on to perform nuclear storage. At this time, the normally open contactors K1 and K2 are in the off state, and the closure of any one will cause the normally open contactor K3 to be disconnected, thereby avoiding the battery 20 being in multiple states. When the true load is used for nuclear storage, the process is as described above, and when the true load is used for nuclear storage and the battery 20 is charged, the normally open contactor K3 cannot be closed. Thus, the device control is more intelligent and safe.

[0041] Specifically, the main control module is any chip module, single-chip microcomputer, etc. that plays a control role. The main control module controls the on-off of the triode module through the second optocoupler module. The triode module is connected to the control end of the main switch, the discharge switch, the charging switch, and the standby switch, respectively. The first optocoupler module, the second optocoupler module, and the other pins of the triode module are connected to the common end. The second normally open output end of the main switch is connected to the control end of the contactor K0 through the first optocoupler module. The second normally open output end of the discharge switch is connected to the control end of the contactor K1 through the first optocoupler module. The second normally open output end of the charging switch is connected to the control end of the contactor K2 through the first optocoupler module. The second normally open output end of the standby switch is connected to the control end of the contactor K3 through the first optocoupler module.

[0042] As shown in Figure 6 and Figure 7 , four switches need to be controlled. The four output ends of the second optocoupler module OC2 are connected to the bases of the four triodes of the triode module, respectively. The emitters of the four triodes are connected to the control ends of the main switch, the discharge switch, and the charging switch, respectively. The first optocoupler module refers to the second optocoupler module. Because the first optocoupler is also used to connect the light signals generated by the third output pin of the discharge switch and the charging switch and other light signals, it is not the focus of the present application and is not shown in the attached drawings. The first optocoupler module, the second optocoupler module, and the triode module play the role of isolating the switch.

[0043] The full-factor monitoring battery 20 remote nuclear storage system of the present application can remotely control the battery 20 to discharge for nuclear storage with a true load, saving energy. It can also be used for 0.1C10 nuclear storage, increasing the use scenarios of the system of the present application, meeting various nuclear storage needs, and connecting the multiple states of the battery 20 through interlocking and other methods, which can avoid the battery 20 being in multiple states, thereby better protecting the battery 20 and making it more safe and reliable.

[0044] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical scheme falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
