With the development of the internet of things technology and the computer technology and the popularization of new energy concepts, the electric automobile develops rapidly, kinetic energy is provided for the electric automobile through the power battery, the non-renewable loss can be reduced, and the call of the era on green energy can be met. At present, electric vehicles are generally used in daily life of people, when the remaining value of a power battery of the electric vehicle reaches a certain value, the electric vehicle needs to go to a battery replacement station to replace the battery, and how to improve the replacement efficiency of the power battery of the electric vehicle becomes a hotspot of current research.
In the prior art, a user needs to go to a power exchanging station to complete the replacement of a power battery of an electric vehicle, that is, a fully charged power battery is stored in the power exchanging station, so as to meet the requirement of the user on the replacement of the power battery. The power battery with insufficient electric quantity value is placed into the power station of the charging and replacing power station by the user, then the charging and replacing power station provides electric quantity through the power grid to complete charging of the power battery, and the cycle is repeated, so that the requirement of replacing the power battery by all users is met.
Obviously, the prior art realizes the requirement of a user for replacing the power battery by depending on the electric energy provided by the power grid, ignores the abnormal condition of power supply of the charging and replacing power station if the power grid cannot work normally, and enables the charging and replacing power station to be incapable of charging and storing energy for the power battery. It can also be understood that the charging and replacing station is charging all power batteries in the station, and the electric quantity values of all power batteries cannot meet the requirement of a user for replacing the power batteries, that is, the charging and replacing station does not have the power batteries with full electric quantity values.
For the technical problem, the situation that a power grid cannot work normally is considered, the electric quantity values of all power batteries in a charging and replacing power station are counted, then the sum of the electric quantity values of all the power batteries is counted, then the batteries to be charged and the batteries to be discharged are determined, based on a charger in the charging and replacing power, the batteries to be charged are discharged by the batteries to be discharged, the long-time waiting of a user is avoided, and the efficiency of replacing the power batteries is improved.
Specifically, the application provides a charging control method for a power battery of a charging and replacing power station. The method is applied to a charging control system of the power batteries of the charging and replacing station, and the charging control system comprises a plurality of power batteries, a charger corresponding to each power battery and a charging controller connected with each charger. The charging controller determines the sum of the residual battery electric quantity values of all the power batteries, determines at least one power battery in all the power batteries as a battery to be charged according to the sum of the residual battery electric quantity values, takes other power batteries except the battery to be charged as discharging batteries, and controls the charger of each power battery to work so that each discharging battery charges each battery to be charged. The method can improve the charging efficiency of the charging and replacing station to the power battery, and can solve the problem that the outside cannot provide electric energy to the charging and replacing station, so that the available power battery cannot be provided.
The following describes technical solutions of embodiments of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture on which the present application is based, and as shown in fig. 1, the network architecture includes a server 1 and a charging and swapping station 2.
The server 1 is specifically a server cluster capable of processing mass data, and a charging control device for a power battery of the charging and replacing station provided by the present application may be integrated or installed therein, where the charging control device may control a working state, i.e., a charging and discharging state, of the charging and replacing station 2 based on the charging control method for a power battery of the charging and replacing station provided by the present application, so as to complete charging of the power battery, so that a power battery capable of performing a battery replacing operation for a user is provided in the charging and replacing station.
The charging and replacing power station 2 specifically refers to an energy station for providing charging for power batteries of the electric automobile and rapidly replacing the power batteries, and consists of a power battery system and a charging system, wherein the power battery system refers to a plurality of power batteries in the charging and replacing power; the charging system refers to a plurality of chargers in the charging and replacing power station and a charging controller connected with the chargers. Based on the communication technology of the internet of things, the charging system can establish communication with the power battery, and the charging and replacing power station 2 and the server can also establish communication.
Example one
Fig. 2 is a schematic flowchart of a charging control method for a power battery of a charging and replacing station, as shown in fig. 2, the method includes:
step 201, the charge controller determines the sum of the residual battery electric quantity values of all the power batteries;
step 202, the charge controller determines at least one power battery as a battery to be charged in each power battery according to the sum of the residual battery electric quantity values, and takes other power batteries except the battery to be charged as discharging batteries;
and 203, controlling the charger of each power battery to work by the charging controller so as to charge each discharging battery for each battery to be charged.
Specifically, the main execution body of the charging control method for the power battery of the charging and replacing station provided by the present application is the charging control device, and as described above, the charging control device may be specifically installed or carried in the server 1.
Before step 201 is executed, it should be explained that the charging control method for power batteries of a charging and replacing power station provided by the present application is applied to a charging control system for power batteries of a charging and replacing power station, where the charging control system includes a plurality of power batteries, a charger corresponding to each power battery, and a charging controller connected to each charger.
As shown in fig. 3, fig. 3 is a schematic structural diagram of a charging and replacing power station, where 3 denotes a power battery system composed of a plurality of power batteries, 4 denotes a charging system composed of a plurality of chargers and a charging controller connected to the chargers, and 5 denotes an ac bus to which charging points need to be connected during operation; and 6, the grid line group to which the charger needs to be connected when in work. Wherein, 3 and 4 can realize communication connection based on internet of things, 4 can acquire the electric quantity value of 3 promptly.
The charger is a bidirectional charger, namely the charger can realize both charging operation and discharging operation, and correspondingly, the charger has a charging working state and a discharging working state, namely the charger converts alternating current into direct current and is in the charging working state, and the charger converts the direct current into alternating current and is in the discharging working state.
Specifically, in step 201, the charge controller controls the charge controller to determine the sum of the remaining battery charge values of the power batteries. Based on the internet of things technology, the charging control device issues the charging system to acquire the electric quantity value of the power battery system, that is, the charging controller acquires the remaining electric quantity value of each power battery, and then the charging controller sums the remaining electric quantity values to acquire the sum of the remaining electric quantity values.
If 5 power batteries are arranged in the charging and replacing power station, assuming that the electric quantity value of the power batteries at full charge is 100% in percentage, the residual electric quantity values are 10%, 20%, 35%, 15% and 25% in sequence, and the charging control device controls the charging controller to determine that the sum of the residual electric quantity values of the power batteries is 105%.
After the charge control device determines the sum of the remaining battery electric quantity values of each power battery, step 202 is executed to control the charge controller to determine at least one power battery as a battery to be charged in each power battery according to the sum of the remaining battery electric quantity values, and to take other power batteries except the battery to be charged as discharging batteries.
Specifically, the charge control device determines the number of the fully chargeable power batteries according to the sum of the residual battery electric quantity values and the full-rated electric quantity value of the power batteries; then, sequencing the power batteries according to the residual battery capacity values of the power batteries, namely sequencing the power batteries from small to large; and determining batteries to be charged and batteries to be discharged according to the sequencing result and the number of the fully chargeable power batteries, wherein the number of the batteries to be charged is the number of the fully chargeable power batteries.
Further, the charging control device performs quotient operation on the sum of the residual battery electric quantity values and the full-rated electric quantity value of the power battery to obtain an integer result, and the integer result is used as the number of the power batteries which can be fully charged; then, the charging controller acquires the residual battery electric quantity values of the power batteries and sorts the residual battery electric quantity values in a descending order; the nth power battery is used as a boundary line, namely the first N power batteries can be used as batteries to be charged, and the nth +1 power batteries are used as discharging batteries.
In the above example, the sum of the remaining battery power values of 5 power batteries in the charging and replacing station is 105%, the sum is subjected to quotient operation with the full power value 100% of the power battery, the obtained integer result is 1, that is, one power battery can be used as a battery to be charged, then the 5 power batteries are sorted according to the remaining battery power values, and the obtained result is: 35%, 25%, 20%, 15%, 10%, and determining the power battery with the remaining battery electric quantity value of 35% as the battery to be charged and the remaining 4 power batteries as the discharging batteries by integrating the quotient operation result and the sequencing result.
Obviously, when a problem occurs in a power grid line in a charging and replacing station, the control method can still charge a discharged battery to meet the battery replacing requirement of a user, and in the prior art, the power battery can be charged only when the power grid line is recovered to be normal, namely, the power supply of the charging and replacing station is normal.
After determining the batteries to be charged and discharged in the charging and replacing station, the charging control device charges the batteries to be charged, and in step 203, controls the charging controller to control the charger of each power battery to work so that each discharged battery charges each battery to be charged.
Specifically, the charging controller controls the contactors of chargers of the power batteries to be closed, wherein the charger corresponding to the battery to be charged works in a charging state, and the charger corresponding to the battery to be discharged works in a discharging state.
Further, the charging control device controls the charging controller to close the contactors of the chargers in the charging and replacing station so as to perform charging operation, or the contactors close the circuit of the chargers to be connected, and the chargers can enter the working state when the circuit is connected.
Correspondingly, the charger connected with the battery to be charged is in a charging working state, and the charger connected with the battery to be discharged is in a discharging working state.
Optionally, when the charger works in a discharging state, the charger is configured to convert the direct current provided by the discharging battery into an alternating current, and transmit the alternating current to the charger corresponding to the battery to be charged under the control of the charging controller.
Specifically, the charger is in a discharging state, that is, the charger with the discharging battery is in a discharging working state, and the discharging battery discharges to provide electric energy for the battery to be controlled, so that the charging battery is charged.
Further, the charging control device controls a contactor of a charging and discharging machine connected with the discharging battery to be closed, then controls a charging controller connected with the charger to convert direct current provided by the discharging battery into alternating current, and provides the alternating current to the charger corresponding to the charged battery.
Optionally, when the charger is in a charging state, the charger is configured to receive, under the control of the charging controller, the alternating current provided by the charger corresponding to the discharge battery, convert the alternating current into direct current, and charge the battery to be charged by using the direct current.
Specifically, in the actual scenario, 6 in fig. 3 is disconnected from the charger, and the charge reset device controls the charge controller connected to the charger associated with the discharged battery, which converts the dc power provided by the discharged battery into ac power. Then, the charging control device transmits the alternating current to a charger corresponding to the battery to be charged, and the charging controller connected with the charger corresponding to the battery to be charged converts the alternating current into direct current and charges the battery to be charged.
As shown in fig. 3, assuming that the power battery 3 is a discharge battery and the power battery 1 is a discharge battery, the charging controller 3 connected to the charger 3 converts the direct current provided by the power battery 3 into alternating current, and then the charging controller transmits the alternating current to the charger 1 via the alternating current bus, and the charging controller 1 connected to the charger 1 converts the transmitted alternating current into direct current and charges the power battery 1.
The charging control device detects whether the electric quantity value of the discharging battery is 0 in real time in the process of charging the battery to be charged, and if the electric quantity value of the discharging battery is 0, the charger corresponding to the discharging battery stops working; if the discharged battery has residual electric quantity, whether the electric quantity value of the battery to be charged is full or not is detected, and if so, the corresponding charger with the charged battery stops working.
It is understood that when the charged battery is fully charged and/or the discharged battery is fully discharged, the charger connected to the charged battery stops.
The application provides a charging control method for a power battery of a charging and replacing power station. The method is applied to a charging control system of the power batteries of the charging and replacing station, and the charging control system comprises a plurality of power batteries, a charger corresponding to each power battery and a charging controller connected with each charger. The charging controller determines the sum of the residual battery electric quantity values of all the power batteries, determines at least one power battery in all the power batteries as a battery to be charged according to the sum of the residual battery electric quantity values, takes other power batteries except the battery to be charged as discharging batteries, and controls a charger of each power battery to work so that each discharging battery charges each battery to be charged. The method can improve the charging efficiency of the charging and replacing station to the power battery, and can solve the problem that the outside cannot provide electric energy to the charging and replacing station, so that the available power battery cannot be provided.
