Therefore, there is a need for an efficient and stable reorganization and discharge method for reorganizing, identifying and controlling the battery packs.

Example 1:
referring to fig. 1, a flow chart of a method for reorganizing and discharging a plurality of mobile energy storage batteries according to an embodiment of the invention is shown. In this embodiment, the method for recombining and discharging the plurality of mobile energy storage batteries includes:
s1, receiving a reorganization discharge instruction, and starting a reorganization discharge control device while acquiring a plurality of mobile energy storage batteries according to the discharge instruction, wherein the reorganization discharge control device comprises a voltage test unit, a reorganization discharge unit, a circuit adjusting unit, a standby battery unit set, a communication unit, a reorganization unit and a voltage sequencing unit; the circuit adjusting unit can adjust the circuit layout of the recombination discharge unit.
Further, reorganizing a mobile energy storage battery is generally a process of generating a new battery with integrity and coordination by using a plurality of mobile energy storage batteries according to a specific circuit layout. It is emphasized that the reorganization of the mobile energy storage battery needs to consider the discharge requirement during the discharge process, and reorganizes the mobile energy storage battery according to the discharge requirement; however, in general, a user cannot well judge how to reorganize, if the reorganization is simply performed in series, a plurality of mobile energy storage batteries cannot be coordinated well, discharge is uneven, and the adoption rate is low, so that the battery performance and the service life of each mobile energy storage battery are affected.
Therefore, the core problem to be solved by the embodiment of the invention is to reasonably realize the recombination of the discharging problem of each mobile energy storage battery.
The embodiment of the invention realizes that the discharging process of the recombination battery depends on a recombination discharging control device, wherein the recombination discharging control device is integrated by a plurality of units, and the core unit comprises a voltage testing unit, a recombination discharging unit, a circuit adjusting unit, a standby battery unit and a voltage sequencing unit.
It should be emphasized that the main function of the voltage testing unit is to measure the terminal voltage of each mobile energy storage battery before discharging, then the voltage sequencing unit performs sequencing on each mobile energy storage battery according to the terminal voltage of each mobile energy storage battery, and further, the circuit adjusting unit and the standby battery unit adjust the circuit layout of the reorganization discharging unit according to the sequencing result until the circuit layout is completed and then external discharging is started. More particularly, after the discharge, the embodiment of the invention also continuously monitors the current of the selected series discharge circuit, and if the current is not in the preset interval, the discharge selection switch is controlled to switch to the next series discharge circuit.
In addition, the spare battery unit set is generally an energy storage battery with stable voltage and current, which is prepared in advance in the recombination discharge control device, and the energy storage battery can be one or a plurality of energy storage batteries; and can have different terminal voltages, its main aim at cooperation a plurality of removal energy storage battery discharges, prevents when combining the removal energy storage battery, and last several battery terminal voltages is less, even all establish ties still can not reach the condition of demand discharge voltage. Of course, part of the spare battery units in the spare battery unit set can also be part of power supplies with stable voltage and good performance, which are directly selected from the mobile energy storage batteries, so that on one hand, excessive battery consumption is saved, and the structure of the recombination discharge control device can be simplified.
S2, testing the terminal voltage of each movable energy storage battery by adopting a voltage testing unit to obtain a plurality of battery terminal voltages corresponding to the plurality of clamping grooves.
Specifically, the clamping groove comprises: a wireless communication module and an access unit. When a plurality of mobile energy storage batteries needing to be recombined are connected into a plurality of clamping grooves, the connection unit is connected with the battery pack, the battery pack is used as a power supply of the clamping grooves to start the wireless communication module, and the clamping grooves also comprise a voltage limiting module which is used for controlling the output voltage of the battery pack so that the output voltage of the battery pack meets the requirements of the wireless communication module. The voltage testing unit receives a plurality of battery terminal voltages sent by the clamping grooves through the wireless communication module. It can be understood that each clamping groove is provided with a wireless communication module, when a plurality of mobile energy storage batteries needing to be recombined are placed in the clamping groove, the batteries can be placed in the clamping groove to supply power, the wireless communication modules of the clamping grooves are started, and terminal voltages of the batteries corresponding to the clamping grooves are sent to the voltage testing unit. Specifically, after the battery is placed in the clamping groove, the wireless communication module of the clamping groove is started, and the mac address, the clamping groove number and the battery terminal voltage of the wireless communication module can be sent to the voltage testing unit through the wireless communication module. After receiving the information sent by the wireless communication module, the voltage testing unit can obtain the battery terminal voltage corresponding to each clamping groove, so that when the battery terminal voltage needs to be sequenced later, the corresponding clamping groove can be corresponding to the port to be reached.
Optionally, the wireless communication module is bound with the card slot, so that the card slot number can be obtained simultaneously only by sending the mac address of the wireless communication module during sending.
For example, the mobile energy storage batteries are 20, the 20 mobile energy storage batteries are placed in the 20 clamping grooves, the voltage test unit is used for testing 20 battery terminal voltages corresponding to the 20 clamping grooves, and the 20 terminal voltages and the 20 clamping grooves are bound to form a corresponding relation.
S3, sequencing the voltages of the battery terminals from large to small by adopting a voltage sequencing unit to obtain a terminal voltage sequencing set, and determining ports corresponding to the battery pack clamping grooves; the communication unit communicates with the card slot and sends a port corresponding instruction to the card slot.
Specifically, according to the received multiple clamping grooves and the corresponding multiple battery terminal voltages, a voltage sequencing unit is adopted to sequence the multiple battery terminal voltages from large to small to obtain a terminal voltage sequencing set, and the terminal voltage corresponds to the clamping grooves, so that the clamping groove sequencing set can be obtained at the same time; and obtaining ports corresponding to the plurality of clamping grooves according to the clamping groove ordered set, and sending port corresponding instructions to the clamping grooves. It can be understood that, since a plurality of batteries are finally required to be placed at the corresponding ports according to the order of the terminal voltages from large to small so as to be combined in series-parallel, the ports which the card slots corresponding to each terminal voltage finally need to reach are required to be obtained. Because the terminal voltage corresponds to the clamping grooves, when the terminal voltage is sequenced, the sequencing of the clamping grooves can be simultaneously obtained, and then the ports corresponding to each clamping groove can be obtained, and the communication unit sends the port corresponding instruction to the clamping grooves, so that the battery is finally connected to the ports according to the sequence from the high terminal voltage to the low terminal voltage.
Optionally, the card slot may communicate with the transmitting device through the wireless communication module, and when the card slot reaches its corresponding port, an arrival instruction is sent to the transmitting device, so that the transmitting device may transmit the card slot to the corresponding port. The conveying device can be integrated with a push rod or a baffle plate and is used for enabling the corresponding clamping groove to reach the corresponding port when receiving the reaching instruction. The detection of the card slot reaching its corresponding port may be accomplished by a sensor or detection device, which will not be further described herein.
Further, after the battery pack is connected to the corresponding port, the battery pack is bound with the port, and the connection between the battery pack and the access unit is disconnected. At this time, the recombination discharge control device performs communication control with the battery pack through the port.
For example, since the sequence of placing the batteries is random, 20 terminal voltages V1-V20 corresponding to 1# -20# slots are measured, and the terminal voltage values are different, it is necessary to compare the terminal voltages, arrange them from large to small, and finally V20, V19, V18 … … V2, V1, where V20> V19> V18> … > V2> V1, and move the slots corresponding to the terminal voltages to the corresponding port positions. It will be understood that the terminal voltage of V20 corresponds to the No. 2 mobile energy storage battery and the No. 20 slot, then it corresponds to the No. 20 slot where it is located being moved to the first port position, the terminal voltage of V19 corresponds to the No. 8 mobile energy storage battery and the No. 19 slot, then it corresponds to the No. 19 slot where it is located being moved to the second port position …, and the remaining batteries also respectively move accordingly, and finally the terminal voltages of the mobile energy storage batteries are finally arranged from large to small, and it should be noted that in this example, the batteries do not correspond to the number of the obtained terminal voltages. This example is only for the card slot corresponding to the terminal voltage, and moving the card slot can move the battery of the corresponding terminal voltage to the corresponding port, so that the terminal voltages of the batteries at the final ports are arranged in order from large to small.
It should be noted that the order of the voltage ordering units is arranged from large to small as required in the present embodiment, but the function of the voltage ordering unit is not limited to this, and it is possible to order the terminal voltages as needed, and the final purpose of the ordering is to group the access batteries. It will be appreciated that the present embodiment is arranged from large to small in order to group the cells that are connected, and that the pressure differential per group is minimal, so that each group that is ultimately obtained can be used. In other situations, for example, when the plurality of groups are used in parallel after the connected batteries are connected in series, the voltage sequencing unit may sequence the voltages of the battery terminals according to the voltage maximum value, the voltage minimum value, the voltage sub-maximum value and the voltage sub-minimum value ….
S4, the combination unit calculates the combination of the movable energy storage batteries which meet the discharge voltage required in the terminal voltage ordered set, and combines the movable energy storage batteries to obtain a recombined battery set.
Specifically, according to the sorting order of the plurality of mobile energy storage batteries, judging whether the uncombined mobile energy storage batteries are larger than the required discharge voltage preset threshold value or not; if the current is larger than the current, the movable energy storage battery singly forms a serial discharge circuit; if the voltage is smaller than the required discharge voltage, the voltage is combined with the next adjacent movable energy storage batteries in series until the sum of the terminal voltages of the movable energy storage batteries is larger than the required discharge voltage; and after judging all the uncombined mobile energy storage batteries according to the arrangement sequence, combining a plurality of recombined mobile energy storage batteries to obtain a recombined discharge set.
Exemplary, the terminal voltages corresponding to the 20 mobile energy storage cells are finally ordered as V20, V19, V18 … … V2, V1, wherein V20>V19>V18>…>V2>V1, in which case 20 mobile energy storage batteries need to be combined. Starting from an uncombined mobile energy storage cell, i.e. from V20, if V20>V0+V x Wherein V0 is the required discharge voltage, V x And if the threshold value is preset, the mobile energy storage battery corresponding to V20 independently forms a series discharge circuit, and then V19 is judged. If V19<V0+V x Then, V19 and V18 are combined in series to judge whether V19+V18 is larger than V0+V x The method comprises the steps of carrying out a first treatment on the surface of the Combining 20 mobile energy storage batteries according to this manner results in a recombined discharge set, e.g. V20, V19+ V18, V17+ V16, V15+
V14、V13+V12、V11+V10+V9、V8+V7+V6、V5+V4+V3、V2+V1]。
Further, if the sum of voltages of the last several non-combined mobile energy storage batteries forming the series discharge circuit is smaller than the required discharge voltage, a standby battery unit is selected from the standby battery unit set, and the standby battery unit and the rest non-combined mobile energy storage batteries are combined into the series discharge circuit. And judging the difference value between the sum of the terminal voltages of the remaining and uncombined mobile energy storage batteries and the required discharge voltage, and selecting a standby battery unit with the terminal voltage larger than and closest to the difference value from the standby battery unit set, so that the voltage of the formed branch circuit is minimum under the condition of meeting the required voltage, and the branch circuit can work stably.
Exemplary, when the mobile energy storage battery corresponding to V20-V1 is assembled, the battery is assembled by V5++ V4+V3>V0+V x Combining them into a series discharge circuit, and continuing to judge V2, and V2+V1<V0+V x And no other mobile energy storage battery can be combined with the mobile energy storage battery after that, at the moment, a candidate battery cell set needs to be called, a standby battery cell is selected, if two standby battery cells 1# and 2# exist, and the corresponding terminal voltages of the 1# and 2# standby battery cells are V21 and V22, at the moment, a specific V0- (V2 + V1) -V is selected x Large and closest to the battery backup of V0- (v2+v1). It will be appreciated that V21 is assumed>V0-(V2+V1)-V x And V22>V0-(V2+V1)-V x And V21<V22, selecting 1# standby battery corresponding to V21 at this time to form a series discharge circuit together with V2+V1, wherein the final recombination discharge set is [ V20, V19+V18, V17+V16, V15+V14, V13+V12, V11+V10+V9, V8+V7+V6, V5+V4+V3, V2+V1+V21 ]]。
S5, according to the recombination battery set, a circuit adjusting unit is adopted to adjust the circuit layout of the recombination discharge unit, so that a plurality of series discharge circuits which are mutually connected in parallel are generated in the recombination discharge unit, and each series discharge circuit is provided with a discharge selection switch.
Specifically, the combination condition of the recombined battery set is obtained, a plurality of regulating switches in the circuit regulating unit are controlled, and the circuit layout of the recombined discharging unit is regulated to be the same as the combination condition of the recombined battery set.
It can be understood that the circuit layout comprises terminals connected with each clamping groove, connecting wires for realizing circuit connection and switches for controlling the connection of each connecting wire, and the positions of the clamping grooves can be moved, so that the movable energy storage batteries can be sequenced according to terminal voltages; the segments connected with the clamping grooves and the connecting wires for realizing circuit connection are connected in a fixed mode, and the change of circuit layout can be realized by controlling the switches connected with the connecting wires. According to the final recombination discharge set, the opening and closing of the switches connected with the connecting wires are controlled, the circuit layout can be adjusted to be that m branches are connected in parallel, and different battery clamping grooves are connected in series in each branch, wherein m is the number of series discharge circuits in the recombination discharge set.
Further, the m paths of branches are connected in parallel through discharge selection switches respectively, and the connected mobile energy storage battery is controlled by controlling the discharge selection switches.
For example, since the final recombination discharge set is [ V20, v19+v18, v17+v16, v15+v14, v13+v12, v11+v10+v9, v8+v7+v6, v5+v4+v3, v2+v1+v21], the circuit layout of the recombination discharge unit is adjusted by the circuit adjusting unit so that 9 branches are connected in parallel, and the first branch includes a battery clamping slot in which a mobile energy storage battery corresponding to V20 is installed; the second branch comprises two battery clamping grooves, the clamping grooves are respectively provided with movable energy storage batteries corresponding to V19 and V18, and the other branches are similar. When discharging is needed, the first branch is conducted through the discharging selection switch, and power is supplied by the first branch.
S6, judging whether the current of the selected series discharge circuit is in a preset interval, and if not, controlling the discharge selection switch to the next series discharge circuit.
For example, after the first branch is discharged, the battery power of the first branch is continuously consumed, and the terminal voltage of the battery of the first branch is continuously reduced; monitoring the voltage of the branch by adopting a preset time interval, comparing the voltage with a preset interval, and controlling a discharge selection switch to a next series discharge circuit when the voltage of the battery of the branch is lower than the preset interval and the electric quantity of the battery of the branch cannot meet the requirement; if the load exceeds the bearing range or the problem occurs in the branch circuit when the load exceeds the preset interval by a certain threshold value, the discharge selection switch is controlled to be switched to the next series discharge circuit so as to realize the protection of the circuit.
Further, a voltage regulating unit and/or a current monitoring unit are arranged on the output trunk, and the voltage regulating unit can control the output voltage of each branch to be the required discharge voltage according to the needs of a user; the current detection unit can detect the main current.
Further, when receiving the reorganization charging instruction, the circuit adjusting unit is controlled to adjust the circuit layout of the reorganization discharging unit to be in a full parallel mode, and a plurality of mobile energy storage batteries connected in parallel are connected in parallel at the moment, so that the plurality of mobile energy storage batteries are charged simultaneously.
And S7, judging whether a series discharge circuit with a current change value larger than a preset current threshold exists, and if so, eliminating the series discharge circuit from the battery discharge circuit by adopting a circuit adjusting unit to obtain an eliminating discharge circuit.
Wherein, judge whether there is the current change value greater than the serial discharge circuit of the preset current threshold value, still include:
according to the equivalent capacitance of the movable energy storage battery and the standby battery unit of each branch, the calculation formula of the equivalent capacitance is as follows:
wherein C is p Representing the equivalent capacitance of the current branch, C i Representing the equivalent capacitance of the ith battery of the current branch, and l represents the number of the mobile energy storage batteries accessed by the current branch;
and calculating to obtain the current change value of the current branch according to the following formula:
wherein i (t) represents a current variation value, deltau represents a voltage function obtained by calculating the current branch end voltage, and t represents discharge time.
It should be explained that, because the capacity, the discharge efficiency and the like of the mobile energy storage battery of each branch circuit change at the moment along with the discharge process, the current change of the branch circuit is directly affected, so that in order to prevent the dangerous phenomena of heating or overload and the like of the serial discharge circuit caused by overlarge current change of the serial discharge circuit where the branch circuit is located, the embodiment of the invention continuously monitors the current change value of each serial discharge circuit and further determines the discharge safety through the current change value.
It can be understood that when the current change value in the series discharge circuit is greater than the current threshold value, which indicates that the terminal voltage of the mobile energy storage battery corresponding to the series discharge circuit is too fast or the output voltage is unstable in the discharging process, and the phenomenon that the circuit of the series discharge circuit is overheated or overloaded is extremely caused, in order to improve the safety, in the embodiment of the invention, the circuit adjusting unit is adopted to reject the series discharge circuit from the battery discharge circuit, so as to obtain a reject discharge circuit, which comprises:
generating a direct-connection discharging circuit by adopting a circuit adjusting unit, wherein the direct-connection discharging circuit only consists of a circuit wire and does not comprise a movable energy storage battery;
a circuit adjusting unit is adopted to open a switch of the series discharging circuit, wherein when the switch is opened, the series discharging circuit is disconnected with the battery discharging circuit;
and after the series discharge circuit is disconnected from the battery discharge circuit, connecting the direct-connection discharge circuit to the battery discharge circuit, wherein the disconnected series discharge circuit is the rejection discharge circuit.
S8, selecting the battery voltage stabilizing units from the battery voltage stabilizing unit set, adding the battery voltage stabilizing units into the rejection discharging circuit to obtain a recombination circuit, and connecting the recombination circuit to the battery discharging circuit again in parallel.
Specifically, the battery voltage stabilizing unit includes one or more battery voltage stabilizing units. The battery voltage stabilizing unit is added in the eliminating discharging circuit because of the instability of the movable energy storage battery in the eliminating discharging circuit in the discharging process. It should be explained that, in the embodiment of the present invention, a battery voltage stabilizing unit is not added to each series discharge circuit before discharging, and the main reason is that the battery voltage stabilizing unit is a device that consumes extremely electric energy resources to ensure circuit stability, and if the battery voltage stabilizing unit is added to each series discharge circuit, serious electric energy resource waste is caused. In addition, as each branch circuit consists of one or more movable energy storage batteries, and the voltage of the batteries is unstable when the batteries are combined, the output voltage of the batteries can be stabilized by arranging the battery voltage stabilizing unit, and when the current change of the batteries is abnormal, the battery voltage stabilizing unit is connected into a circuit, so that the output current of the batteries is stable, and resources are saved.
