With the shortage of oil resources and the development of battery technology, electric vehicles have approached or even surpassed traditional fuel vehicles in terms of performance and economy, and have begun to be gradually promoted and applied worldwide. The new generation of energy-saving and environmentally friendly vehicles represented by electric vehicles is an inevitable trend in the development of the automobile industry and has become a general consensus.

[0006] By adopting the above technical solution, the battery in the discharged state charges the battery in the charged state. If the voltage is insufficient, the voltage is supplemented by an external power supply (State Grid). This not only ensures the stability of the voltage at the power supply end, but also makes it less likely to waste the electric energy of the discharged battery, thus saving electricity costs.

[0011] Optionally, a further method of controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the charge battery number includes: Determine the idle battery number based on the discharged battery number, the charged battery number and the battery number when no matching solution exists; Get the estimated plan of idle battery numbers; When the estimated plan is a discharge state, the estimated discharge planning time is obtained; When the estimated discharge planning time is less than the preset waiting critical time, the idle battery number is defined as the discharge battery number and a preferred matching scheme is generated, and a preset idle mark is attached to the discharge battery number; Based on the expected discharge planning time, the preferred matching scheme is adjusted to obtain a first adjusted matching scheme and the battery corresponding to the discharge battery number and the external power supply are controlled to charge the battery corresponding to the corresponding charging battery number in the first adjusted matching scheme, but the discharge battery number and the external power supply with an idle mark supply power to the battery corresponding to the corresponding charging battery number after the expected discharge planning time.

[0012] By adopting the above technical solution, if there is no matching solution, the corresponding battery that is about to be discharged will be used as the discharge battery for solution design, but the corresponding discharge battery must be charged at the corresponding discharge time, which improves the flexibility of matching solution design.

[0014] By adopting the above technical solution, batteries that are not discharged now but may be discharged later are also included in the discharge batteries, so as to rationally plan the matching scheme and improve the flexibility of matching scheme design.

[0015] Optionally, a further optimization method of the first adjustment matching scheme is also included, the method comprising: Determine the direct discharge battery number based on the first adjustment and matching scheme and the discharge battery number; Before the expected discharge planning time, the battery number and the external power supply supply power to the battery corresponding to the charging battery number corresponding to the discharge battery number with the idle mark until the expected discharge planning time.

[0016] By adopting the above technical solution, charging is performed in advance. Under the condition of ensuring the same amount of waste, the rechargeable battery does not need to wait and waste charging time, thereby improving the charging efficiency of the rechargeable battery.

[0017] Optionally, the method further includes controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the charge battery number when the matching solution does not exist, the method comprising: Regenerate the matching scheme after defining any number of rechargeable battery numbers as idle battery numbers; If no matching solution exists after all the rechargeable battery numbers are defined, the external power supply directly supplies power to the battery corresponding to the rechargeable battery number; If a matching solution exists, obtain the charging quantity corresponding to the rechargeable battery number in the matching solution; An optimal matching solution is determined based on the charging quantity and output as a matching solution.

[0035] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-Figure 8 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] The present application embodiment discloses a battery intelligent charging method. Figure 1 , a battery intelligent charging method comprising: Step 100: Get the battery number and battery status.

[0037] The battery number is the number of each battery. Since the batteries are in the same area during charging and discharging, the batteries can be numbered to identify the corresponding batteries. Since the base is generally immobile, the corresponding base number can be set, that is, the battery number is the base number. The battery status is the status of the battery, which is generally the charging state, discharging state and idle state.

[0038] Step 101: Classify the battery numbers based on the battery status to obtain the charging battery numbers in a preset charging status and the discharging battery numbers in a preset discharging status.

[0039] The charging state is the state in which the battery is performing a charging action. The discharging state is the state in which the battery is performing a discharging action. The classification method here is to determine the corresponding state.

[0040] Step 102: Obtain the discharge voltage of the discharge battery number.

[0041] The discharge voltage is the voltage of the discharge battery number when discharging. The device obtained here can be a voltmeter.

[0042] Step 103: Determine the supplementary voltage based on the preset rated charging voltage and discharging voltage.

[0043] The rated charge voltage is the voltage that can achieve the best charge state. The supplementary voltage is the additional voltage required in addition to the discharge voltage. It is determined by subtracting the discharge voltage from the rated charge voltage.

[0044] Step 104: Control the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the charge battery number.

[0045] The voltage provided by the external power supply is the supplementary voltage.

[0046] Reference Figure 2 , the method of controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the rechargeable battery number includes: Step 200: Obtain the required power of the charging battery number and the remaining power of the discharging battery number.

[0047] The required power is the power required by the battery corresponding to the charging battery number. This can be obtained by calculation, that is, measuring the current power, and then manually inputting the required power. If no input is made, the default is full power, and then subtracting the two to get the required power. The remaining power is the power of the battery corresponding to the discharge battery number. The method of obtaining it is measurement.

[0048] Step 201: searching for corresponding excess power from a preset power supply database based on the remaining power.

[0049] The surplus power is the power that can actually be used on the battery corresponding to the rechargeable battery number. The database here stores the mapping relationship between the surplus power and the surplus power. Since it is inevitable that there will be some loss during the battery discharge process, and when connected to an external power supply, the external power supply will also replenish some power, so it is necessary to conduct an experiment at this time. That is, the battery with the remaining power is matched with the external power supply, and when all the power of the battery is consumed, observe the replenishment of the charged battery. When the system receives the corresponding surplus power, it automatically finds the corresponding surplus power from the database for output.

[0050] Step 202: Matching the power based on the surplus power and the required power to obtain the discharge battery numbers and the charge battery numbers that are successfully matched, and form a matching battery group.

[0051] The matching battery group is a group formed by the matched discharge battery number and the charged battery number. The matching condition is that the excess power and the required power are the same or similar. The specific matching process will be described in the subsequent steps and will not be repeated here.

[0052] Step 203: Control the battery corresponding to the discharge battery number in the matching battery pack and the external power supply to charge the battery corresponding to the charge battery number.

[0053] The power levels of the charged battery and the discharged battery are as close as possible and the power level of the discharged battery exceeds that of the charged battery, to ensure that the required power level of the charged battery can be fully charged before the discharge is completed without having to replace the charging source in the subsequent process.

[0054] Reference Figure 3 The method for matching the excess power and the required power to obtain the successfully matched discharge battery number and charge battery number includes: Step 300: Combining the excess power in any number to form a sum of excess power.

[0055] The excess power sum is the sum of the excess power.

[0056] Step 301: arbitrarily select the excess power and the required power to subtract them to obtain the power difference, and define the power difference greater than 0 as a positive power difference.

[0057] The power difference is the difference in power. A positive power difference means that the excess power and the corresponding power can meet the power demand requirement.

[0058] Step 302: Determine a matching solution based on the positive power difference.

[0059] The matching scheme is that the charging battery numbers corresponding to the required power are matched with the surplus power and the corresponding discharging battery numbers according to the pre-matching conditions.

[0060] The matching condition is that the power difference between the charging battery number corresponding to the required power and the corresponding excess power and the corresponding discharge battery number is a positive power difference and the discharge battery numbers corresponding to any two charging battery numbers corresponding to the required power are not repeated.

[0061] The final matching solution is the supply and demand relationship formed by the charging battery numbers and discharging battery numbers that meet the matching requirements.

[0062] Step 303: Screen the matching solutions based on the preset screening conditions to obtain the preferred matching solution.

[0063] The screening condition is that the sum of the positive power differences in the matching scheme is the smallest. The preferred matching scheme is the matching scheme that has been screened by the screening condition.

[0064] Step 304: Determine the successfully matched discharge battery numbers and charge battery numbers based on the priority matching scheme.

[0065] Reference Figure 4, a further method of controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the rechargeable battery number includes: Step 400: Determine the idle battery number based on the discharged battery number, the charged battery number and the battery number when no matching solution exists.

[0066] The idle battery number is the number of the battery except the discharged battery number and the charged battery number in the battery number. The determination method is elimination method.

[0067] Step 401: Obtain an estimated plan of idle battery numbers.

[0068] The estimated plan is the content that is expected to be carried out, such as charging or discharging. Here, the estimated plan is input manually, that is, the battery plan is drawn up manually according to today's work plan.

[0069] Step 402: Obtain the estimated discharge planning time when the estimated planning is the discharge state.

[0070] The estimated discharge planning time is the estimated execution time of the plan when the estimated planning is in the discharge state. When the estimated planning is discharge, it means that the idle battery number will be converted into the discharge battery number.

[0071] Step 403: When the estimated discharge planning time is less than the preset waiting critical time, define the idle battery number as the discharge battery number and generate a preferred matching solution, and attach a preset idle mark to the discharge battery number.

[0072] The critical waiting time is the maximum waiting time that can be performed in a short period of time, that is, the time that is generally allowed to not charge in a short period of time except for emergencies. It is set manually. The idle mark is a mark that this discharge battery number is idle at present but will become a discharge battery number after the estimated discharge planning time.

[0073] Step 404: Based on the expected discharge planning time, the preferred matching scheme is adjusted to obtain a first adjusted matching scheme and the battery corresponding to the discharge battery number and the external power supply are controlled to charge the battery corresponding to the corresponding charging battery number in the first adjusted matching scheme, but the discharge battery number and the external power supply with an idle mark supply power to the battery corresponding to the corresponding charging battery number after the expected discharge planning time.

[0074] The first adjustment matching scheme is a scheme for adjusting certain parts of the preferred matching scheme. Specifically, it is "controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the corresponding charging battery number in the first adjustment matching scheme, but the discharge battery number and the external power supply with the idle mark supply power to the battery corresponding to the corresponding charging battery number after the expected discharge planning time."

[0075] Reference Figure 5 , and further comprising a method for generating a preferred matching solution when the expected plan is a preset charging state, the method comprising: Step 500: Obtain the estimated charging planning time when the estimated planning is the charging state.

[0076] The estimated charging planning time is the estimated execution time of the plan when the estimated planning is in the charging state. When the estimated planning is in the charging state, it means that the idle battery number will be converted into the charging battery number.

[0077] Step 501: When the expected charging planning time is earlier than the expected discharging planning time, define the idle battery number that is expected to be in the charging state as the charging battery number and generate a preferred matching solution, and attach an idle mark to the charging battery number.

[0078] The expected charging planning time is earlier than the expected discharging planning time, which means that the number of charging battery numbers will change before the corresponding idle battery numbers become discharging battery numbers. At this time, there may be a better solution than the first adjustment solution, so the idle battery numbers that are expected to be planned as charging state need to be added to it.

[0079] Step 502: adjusting the preferred matching solution based on the estimated discharge planning time to obtain a second adjusted matching solution.

[0080] The second adjustment matching scheme is a scheme for adjusting certain parts of the preferred matching scheme.

[0081] Step 503: Control the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the corresponding charging battery number in the second adjustment and matching scheme, but the discharge battery number and the external power supply corresponding to the charging battery number with an idle mark charge the battery corresponding to the charging battery number with an idle mark after the expected charging planning time, and the discharge battery number and the external power supply with an idle mark supply power to the battery corresponding to the corresponding charging battery number after the expected discharge planning time.

[0082] Reference Figure 6 , further comprising a method for further optimizing the first adjustment matching scheme, the method comprising: Step 600: Determine the number of the directly discharged battery based on the first adjustment and matching scheme and the number of the discharged battery.

[0083] The direct discharge battery number is the discharge battery number that does not belong to the first adjustment matching solution, that is, the battery number that is directly discharged back to the national grid. Since the matching solution does not exist in the previous process, the excess power corresponding to these direct discharge battery numbers will definitely not be greater than the required power.

[0084] Step 601: Before the expected discharge planning time, the battery number and the external power supply are used to supply power to the battery corresponding to the charging battery number corresponding to the discharge battery number with an idle mark until the expected discharge planning time.

[0085] By charging in advance, the rechargeable battery does not need to wait and waste charging time while ensuring the same amount of waste, which improves the charging efficiency of the rechargeable battery.

[0086] Reference Figure 7 , and also includes a method for controlling the battery corresponding to the discharge battery number and the external power supply to charge the battery corresponding to the charge battery number when the matching scheme does not exist, the method comprising: Step 700: Define any number of rechargeable battery numbers as idle battery numbers and then regenerate a matching solution.

[0087] The matching scheme regenerated here does not include the charged battery number defined as the free battery number.

[0088] Step 701: If no matching solution exists after all the rechargeable battery numbers are defined, the external power supply directly supplies power to the battery corresponding to the rechargeable battery number.

[0089] Here, when no matching solution exists after all the rechargeable battery numbers are defined, it means that they cannot be matched normally. Even if there is only one rechargeable battery number, there is no way to generate a matching solution. In this case, they can only be powered by an external power supply.

[0090] Step 702: If a matching solution exists, obtain the charging quantity corresponding to the rechargeable battery number in the matching solution.

[0091] The charging quantity is the number of rechargeable battery numbers. The acquisition method is the counter counting method. If it exists, it means that if the rechargeable battery numbers outside this matching scheme are removed, normal matching can be achieved.

[0092] Step 703: Determine the optimal matching solution based on the charging quantity and output it as the matching solution.

[0093] The best matching solution is the solution with the largest number of charges and is the optimized matching solution. The matching solution is determined by starting with the solution with the largest number of charges, and then outputting the matching solution immediately when there is a matching solution.

[0094] Based on the same inventive concept, an embodiment of the present invention provides a battery intelligent charging system.
