[0032] Figure 1 The present invention provides a schematic diagram of an application scenario of a battery charging method provided in an embodiment of the present invention. The battery charging method can be used to charge multiple batteries using one charging pile. After the charging pile 10 is connected to multiple batteries 20, the charging pile 10 counts the access time of each battery 20 and obtains the charging information sent by each battery 20. The charging pile 10 uses the access time and charging information of each battery 20 to charge each battery 20 in turn until each battery 20 is fully charged.

[0033] The following combination Figure 1 The battery charging method of the embodiment of the present application is described in detail.

[0034] Figure 2 A schematic flow chart of a battery charging method provided by the present application is shown, referring to Figure 2 , the method is described in detail as follows:

[0035] S101: If the charging pile is connected to multiple batteries, obtain the connection time of the multiple batteries.

[0036] In this embodiment, a plurality of charging guns may be provided on a charging pile, and each charging gun may be connected to a battery, that is, the charging pile may charge a battery through each charging gun.

[0037] In this embodiment, the multiple batteries may be batteries connected at the same time, or may be batteries connected at different times.

[0038] In this embodiment, the battery may be a battery installed in a car, a tram, a bus, or the like.

[0039] In this embodiment, when the charging pile detects that a battery is connected, it records the time when the battery is connected. The battery connection time can be associated with the number of the charging gun connected to the battery, so as to quickly find the connection time corresponding to each battery.

[0040] S102, receiving charging information sent by the multiple batteries in real time, wherein the charging information includes a charging current and / or a charging voltage required for the batteries to be charged at a current time.

[0041] In this embodiment, after the battery is connected to the charging pile, the battery sends the required charging current and / or charging voltage to the charging pile in real time. In this application, the real-time charging current and / or charging voltage sent by the battery is recorded as charging information, wherein the real-time sending can be sent at a preset time interval, for example, the preset time interval can be 1 second, 2 seconds or 3 seconds, etc., which can be set as needed.

[0042] As an example, the charging information may be 20V and 20A.

[0043] The charging current and / or charging voltage sent by the battery may be calculated by the battery based on its own material and temperature, etc.

[0044] In this embodiment, after the battery is connected to the charging pile, the charging mode of the battery can also be sent to the charging pile. The battery charging mode includes a continuous charging mode of constant current and constant voltage, and a pulse charging mode.

[0045] For example, lithium batteries are mostly charged in a continuous charging mode with constant current and constant voltage, while lead-acid batteries are mostly charged in a pulse charging mode.

[0046] S103: Charge the multiple batteries in turn based on the access time and the charging information.

[0047] In this embodiment, after receiving the charging information sent by each battery in real time, the charging pile can determine the charging order of the batteries according to the charging information and the access time of the batteries, and charge each battery according to the charging order.

[0048] Specifically, if all batteries are in a constant current and constant voltage continuous charging mode, one battery can be fully charged before charging another battery according to the order in which the batteries are connected.

[0049] For example, if the batteries connected to the charging pile at the current time include battery A, battery B and battery C, and they are sorted in order of connection time: battery A, battery B and battery C, battery A, battery B and battery C are all in constant current and constant voltage continuous charging mode, the charging information of battery A at the current time includes a charging voltage of 20V and a charging current of 20A; the charging information of battery B at the current time includes a charging voltage of 30V and a charging current of 30A; the charging information of battery C at the current time includes a charging voltage of 25V and a charging current of 25A.

[0050] The charging pile first charges battery A with a charging voltage of 20V and a charging current of 20A. After battery A is fully charged, battery A sends a stop charging request to the charging pile, and the charging pile stops charging battery A.

[0051] The charging pile charges battery B at a charging voltage of 30V and a charging current of 30A. After battery B is fully charged, battery B sends a stop charging request to the charging pile, and the charging pile stops charging battery B.

[0052] Finally, the charging pile charges battery C with a charging voltage of 25V and a charging current of 25A. After battery C is fully charged, battery C sends a stop charging request to the charging pile, and the charging pile stops charging battery C.

[0053] Specifically, if all batteries are in pulse charging mode, the charging pile can first charge the battery that was connected earlier and whose charging current or charging voltage in the charging information at the current time is greater than 0. When the charging current or charging voltage of the battery is equal to 0, the next battery will be charged. In this way, multiple batteries will be charged in turn until all batteries are fully charged.

[0054] For example, if the batteries connected to the charging pile at the current time include battery D and battery E, and they are sorted in order of connection time: battery D and battery E, battery D and battery E are both in pulse charging mode, and the charging information of battery D at the current time includes a current of 20A; the charging information of battery E at the current time includes a current of 30A.

[0055] Since the charging currents of battery D and battery E are both greater than 0, and battery D was connected earlier, the charging pile first charges battery D with a charging current of 20A until the charging current sent by battery D to the charging pile is equal to 0, and then stops charging battery D. Since the charging current of battery E is always greater than 0, the charging pile starts charging battery E with a charging current of 30A until the charging current sent by battery E to the charging pile is equal to 0, and then stops charging battery E.

[0056] After stopping charging of battery E, if the charging current sent by battery D to the charging pile is greater than 0, battery D continues to be charged, and battery D and battery E are charged in turn in a cycle according to the above method until battery D and battery E are fully charged.

[0057] In an embodiment of the present application, if there are multiple batteries connected to the charging pile, the charging pile obtains the access time of the multiple batteries; and receives charging information sent by the multiple batteries, wherein the charging information includes the charging current and / or charging voltage required for the battery to be charged at the current time; finally, based on the access time and the charging information, the multiple batteries are charged in turn; in the present application, the charging pile can charge multiple batteries in turn, thereby improving the utilization rate of the charging pile.

[0058] like Figure 3 As shown, in a possible implementation manner, the implementation process of step S103 may include:

[0059] S1031, sorting the multiple batteries according to the order of the access time to obtain sorted batteries.

[0060] S1032: Determine a target battery that needs to be charged at the current time based on the charging information and the sorted batteries.

[0061] In this embodiment, after the charging pile stops charging a battery, it is necessary to re-determine the battery that needs to be charged at the current time, which is recorded as the target battery in this application.

[0062] Since only batteries with charging information greater than 0 are the batteries that need to be charged at the current time, it is necessary to determine the target battery based on the charging information. In addition, following the principle of first come first charge, the determination of the target battery also needs to refer to the access time of each battery.

[0063] like Figure 4 Specifically, the implementation process of step S1032 may include:

[0064] S10321. Determine a first candidate battery based on the charging information, wherein the first candidate battery is a battery whose charging information is greater than a first preset value.

[0065] In this embodiment, the first preset value may be 0. A battery having charging information greater than 0 is selected from the plurality of batteries as a first candidate battery.

[0066] S10322: Use the battery with the earliest connection time among the first candidate batteries as the target battery.

[0067] In this embodiment, the battery ranked at the front is selected from the first candidate batteries as the target battery.

[0068] It should be noted that when a battery is just connected to a charging pile, the charging current and / or charging voltage in the charging information sent by the battery to the charging pile are both greater than 0.

[0069] S1033: Charge the target battery based on the charging information of the target battery.

[0070] In this embodiment, after the target battery is determined, the charging pile can output a corresponding charging current and / or charging voltage to charge the target battery according to the charging current and / or charging voltage required by the target battery in the charging information.

[0071] In this embodiment, when the charging pile is charging the target battery, the target battery will send the charging information required at the current time to the charging pile in real time. If the charging voltage and / or charging current in the charging information required at the current time sent by the target battery is different from the voltage and / or current being output by the charging pile, the output current or voltage of the charging pile changes with the change of the charging information required at the current time.

[0072] Optionally, when the charging pile is charging the target battery, if the charging pile receives a stop charging instruction sent by the target battery, the charging pile stops charging the target battery.

[0073] Optionally, when the charging pile is charging the target battery, if the charging pile detects that the target battery is disconnected, the charging pile stops charging the target battery.

[0074] Optionally, when the charging pile is charging the target battery, if the current charging information sent by the target battery and received by the charging pile is equal to a third preset value, the charging pile stops charging the target battery.

[0075] In this embodiment, the third preset value may be 0.

[0076] S1034, after stopping charging the target battery, re-determine the target battery that needs to be charged at the current time based on the charging information and the sorted batteries, and charge the target battery based on the charging information until the charging of the multiple batteries is completed.

[0077] In this embodiment, after stopping charging of a battery, a target battery may be newly determined and the charging of the determined target battery may continue.

[0078] For example, the batteries currently connected to the charging pile include battery A, battery B, battery C, battery D, and battery E. Sorted by access time, they are battery A, battery B, battery C, battery D, and battery E. At the current time, the charging information of battery A, battery B, battery D, and battery E is greater than 0, so battery A, battery B, battery D, and battery E are the first candidate batteries. Since battery A is connected first, the charging pile charges battery A first. After a period of time, the charging pile receives a stop charging request sent by battery A, indicating that battery A is fully charged, and the charging pile stops charging battery A.

[0079] After the charging pile stops charging battery A, only battery B, battery D, and battery E are the first candidate batteries at the current time, and battery B is connected the earliest, so the charging pile charges battery B. After a period of time, the charging pile receives the charging information sent by battery B equal to 0, and the charging pile stops charging battery B.

[0080] After the charging pile stops charging battery B, only battery D and battery E are the first candidate batteries at the current time, and battery D is connected earlier, so the charging pile charges battery D. After a period of time, the charging pile receives the charging information sent by battery D equal to 0, and the charging pile stops charging battery D.

[0081] After the charging pile stops charging battery D, the charging information of battery B and battery E is greater than 0 at the current time, that is, battery B and battery E are the first candidate batteries, and the access time of battery B is earlier, so the charging pile charges battery B. After a period of time, the charging pile receives the stop charging instruction sent by battery B, and the charging pile stops charging battery B.

[0082] After the charging pile stops charging battery B, the charging information of battery E is greater than 0 at the current time, that is, battery E is the first candidate battery, and the charging pile charges battery E. After a period of time, the charging pile receives a stop charging instruction sent by battery E, and the charging pile stops charging battery E.

[0083] After the charging pile stops charging battery E, the charging information of battery D is greater than 0 at the current time, that is, battery D is the first candidate battery, and the charging pile charges battery D until battery D is fully charged.

[0084] In the embodiment of the present application, the charging pile can automatically determine the target battery according to the charging information of the battery connection time and the current time of the battery, and charge the target battery. It can ensure that the battery connected earlier is fully charged as early as possible, and at the same time, it can ensure that the next battery is automatically charged when the charging pile is idle, so as to achieve the purpose of automatic cycle charging of multiple batteries, so that the charging pile has no idle time until all batteries are fully charged, thereby improving the utilization rate of the charging pile.

[0085] like Figure 5 As shown, in a possible implementation manner, the implementation process of step S1033 may include:

[0086] S10331, determining whether there is charging information less than a second preset value at the current time.

[0087] In this embodiment, the second preset value may be 0.

[0088] Determining whether there is charging information less than the second preset value in the charging information is to determine whether there is a battery that needs to be discharged at the current time. When the battery is in pulse charging mode, some pulse charging has negative pulse charging, and negative pulse charging is the process of battery discharge.

[0089] S10332: If the charging information less than the second preset value does not exist, based on the current charging information of the target battery, the target battery is charged using the current or voltage of the charging pile itself.

[0090] In this embodiment, if there is no charging information less than the second preset value, the charging pile can only use the voltage or current of the charging pile itself to charge the target battery when charging the target battery. The voltage or current of the charging pile itself is obtained from the external power supply through the connection of the charging pile with the external power supply, and is obtained after voltage or current conversion. The external power supply does not include the battery connected to the charging pile at the current time.

[0091] S10333: If the charging information whose value is smaller than the second preset value exists, record the battery corresponding to the charging information whose value is smaller than the second preset value as a second candidate battery.

[0092] In this embodiment, if there is charging information less than 0 at the current time, it means that there is a battery that needs to be discharged at the current time. In this application, the battery that needs to be discharged at the current time is recorded as the second candidate battery.

[0093] S10334: Receive a discharge current of the second candidate battery.

[0094] In this embodiment, if there is a battery that needs to be discharged among the batteries at the current time, and there are multiple batteries that need to be discharged, the second candidate battery ranked at the front can be controlled to be discharged, and the discharge current discharged by the battery is collected.

[0095] Optionally, multiple second candidate batteries may be discharged simultaneously, and discharge currents of the multiple second candidate batteries may be collected.

[0096] Optionally, any second candidate battery may be discharged to collect the discharge current of the second candidate battery.

[0097] S10335: Charge the target battery based on the discharge current and the charging information of the target battery.

[0098] In this embodiment, in order to prevent the electricity discharged by the second candidate battery from being wasted, the discharge current discharged by the second candidate battery can be recovered by the charging pile, and the recovered discharge current can be used to charge the target battery.

[0099] Specifically, the implementation process of step S10335 may include:

[0100] S103351: Based on the charging information of the target battery, determine whether the discharge current meets the charging requirement of the target battery.

[0101] In this embodiment, whether the discharge current meets the charging requirement of the target battery mainly determines whether the discharge current is sufficient for charging the target battery.

[0102] Specifically, when judging whether the discharge current meets the charging requirement of the target battery, the charging pile may be used to perform voltage change or current conversion on the discharge current to obtain the converted voltage or current.

[0103] The converted voltage is compared with the charging voltage in the charging information of the target battery at the current time. If the converted voltage is less than the charging voltage in the charging information of the target battery at the current time, the discharge current does not meet the charging demand of the target battery. Otherwise, the discharge current meets the charging demand of the target battery.

[0104] The judgment of the converted current is the same as that of the converted voltage, and the above judgment can be referred to.

[0105] S103352: If the discharge current does not meet the charging requirement of the target battery, the target battery is charged by using the discharge current and the current or voltage of the charging pile itself.

[0106] In this embodiment, if the discharge current does not meet the charging requirements of the target battery, the charging pile needs to use the current or voltage of the charging pile itself to supplement the discharge current when charging the target battery, that is, use the discharge current and the current or voltage of the charging pile itself to charge the target battery.

[0107] S103353: If the discharge current meets the charging requirement of the target battery, use the discharge current to charge the target battery.

[0108] In this embodiment, if the discharge current meets the charging requirement of the target battery, the discharge current can be used to charge the target battery without using the power of the charging pile itself to charge the target battery.

[0109] In the embodiment of the present application, the charging pile recovers the discharge current released by the battery and uses the discharge current to charge a battery, which can reduce energy waste.

[0110] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0111] Corresponding to the battery charging method described in the above embodiment, Figure 6 A structural block diagram of a charging pile provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.
