Referring to fig. 1, fig. 1 is a block diagram illustrating a charging device according to a preferred embodiment of the invention.
The charging device 100 is arranged on a parking space corresponding to a community and used for charging a vehicle parked on the parking space. The charging device 100 may be a charging pile, such as a floor type charging pile, a wall-mounted charging pile, and the like. In this embodiment, the charging device 100 includes a first metering element 10, a second metering element 20, a control module 30, an inquiry module 40 and a reminder module 50, where the first metering element 10, the second metering element 20, the inquiry module 40 and the reminder module 50 are all electrically connected to the control module 30, so as to send information to the control module 30 and receive a control instruction sent by the control module 30.
In the present embodiment, the first metering element 10 is used for metering the charging current of the charging device 100 after a vehicle is inserted into the charging device 100; the second metering element 20 is used for metering the amount of electricity charged to the vehicle by the charging device 100 when the charging device 100 is inserted into the vehicle. It is understood that the first metering element 10 may be an ammeter and the second metering element 20 may be an electric energy meter. In the present embodiment, when the vehicle is connected to the charging device 100, the first gauge 10 and the second gauge 20 start to operate, and the charging current and the charged amount at the same time are recorded in synchronization with each other. In the present embodiment, the first metering element 10 and the second metering element 20 transmit charging information including a charging current and a charged amount to the control module 30 at regular intervals to feed back the charging state of the charging device 100. For example: if the vehicle 10 is connected to the charging device 100 for charging, and the fixed period is 2 minutes, charging information is reported at 10 points 2: the charging current was 16A, and the charged amount was 0.53 AH; reporting charging information at 10 points and 4 points, wherein the charging current is 16A, and the charged amount is 1.06 AH; 10 o' clock and 6 min, the charging current was 16A, and the charged amount was 1.69 AH.
Furthermore, the conventional electric vehicle is generally a ternary lithium battery or a lithium iron phosphate battery, and due to the influence of the material of the battery, the charging current of the battery has a certain rule in the charging process. Referring to fig. 2, fig. 2 is a waveform diagram of a charging current during a charging process of a battery, and it can be seen from fig. 2 that the charging current of the battery is low and constant at an initial stage of charging; the charging current is maximum and constant in the middle charging period; and in the later charging period, the charging current is gradually reduced until the charging is finished. It can be understood that the charging efficiency of the battery is high when the charging current is large, and the charging efficiency is low when the charging current is small, so that the charging efficiency starts to decrease when the charging current decreases. Correspondingly, in the later stage of battery charging, the battery is in a deep charging state, and certain damage can be brought to the battery by continuous charging. In the present embodiment, a node at which the battery charging current starts to decrease from the maximum charging current is defined as a charging inflection point, and if the charging current continues to decrease from the maximum current during charging, the charging inflection point is experienced during charging, and overcharging may occur. It can be understood that if the charging inflection point of the battery can be monitored, damage of the battery due to overcharge can be prevented. Correspondingly, the charged quantity of the battery from the minimum electric quantity to the charging inflection point is defined as the early warning electric quantity, and if the charged quantity exceeds the early warning electric quantity in the charging process, the condition of overcharging exists.
Further, in this embodiment, before the user charges the vehicle with the charging device 100 each time, the charging device 100 may be activated by scanning a code or in other ways by a charging application, and then the control module 30 controls the charging device 100 to charge the vehicle. In a charging period from the start of charging to the end of charging, the first metering element 10 and the second metering element 20 synchronously record the charging current and the charged amount in real time and transmit the charging current and the charged amount to the control module 30 at regular intervals. After the charging is finished, the control module 30 analyzes the charging current recorded by the first metering element 10, and analyzes whether the charging current continuously decreases during the charging process, and if the charging current continuously decreases, it indicates that the overcharging occurs during the charging process, and as shown in fig. 2, the control module 30 records the charged amount from the beginning of charging to the time point when the overcharging occurs, as the reference value of the early warning electric quantity. For example: the time recorded by the first metering element 10 for starting charging is 10 points and 2 minutes, and the charging current is 16A; 10 points, 4 points, 16A; 11 points 2 points, 8A; 11, 4, 6A; and 4A at 11: 6, the time when overcharge occurs is 11: 2, and the control module 30 obtains the charged amount recorded by the second metering element 20 at 11: 2 as the reference value of the early warning electric quantity.
Further, since the charging of the user has a certain regularity, the charging is generally performed when the electric quantity is 5% -20%, and since the remaining electric quantity of the battery is unknown and may be different when the user starts charging each time, the more the charging data of the user recorded by the charging device is, the more the early warning electric quantity of the battery can be calculated through the multiple early warning electric quantity reference values. It can be understood that the early warning electric quantity is the maximum value in the multiple early warning electric quantity reference values.
For example: assuming that the remaining power of the user is 50% during the first charging, the reference value of the early warning power required by the charging to the charging inflection point is 6AH, the remaining power of the user is 40% during the second charging, the reference value of the early warning power required by the charging to the charging inflection point is 8AH, the initial charging power for the nth charging is 5%, the reference value of the early warning power required by the charging to the charging inflection point is 16AH, and if the reference value of the early warning power for the nth charging is 16AH, the early warning power of the battery is 16 AH. After the control module 30 calculates the early warning electric quantity, a matching relationship between the early warning electric quantity and the charging application program account of the user is established and stored, so that charging monitoring is performed according to the early warning electric quantity when the charging application program account starts charging next time.
Further, after the vehicle is charged, the control module 30 of the charging device 100 determines whether an account of a charging application program of the vehicle records the early warning electric quantity. If the early warning electric quantity is recorded, it indicates that the charging device 100 has already calculated the early warning electric quantity of the vehicle of the charging account, and can perform charging reminding, so that charging monitoring will be performed when the vehicle is charged; if the early warning electric quantity does not exist, the charging current and the charged quantity are further recorded, and the early warning electric quantity of the vehicle is calculated. Further, when the vehicle has recorded the warning power, the first metering element 10 and the second metering element 20 respectively monitor the charging current and the charged amount during the charging process of the user and transmit the charging current and the charged amount to the control module 30. The control module 30 determines whether the charging current is reduced each time the charging current is received, and determines that the charging state of the charging device 100 is abnormal if the charging current is continuously reduced. Further, in the charging process, the charging current has certain fluctuation, so that the charging state cannot be determined to be abnormal only when the charging current is monitored to be reduced once, and the charging state can be determined to be abnormal only when the charging current is monitored to be continuously reduced for multiple times, so that the abnormal charging state needs to be further analyzed. In this embodiment, when the control module 30 monitors that the charging current decreases at least twice continuously within a preset time, it determines that the charging state of the charging device 100 is abnormal. Further, the preset time should be at least longer than the two fixed periods, so as to ensure that the charging current transmitted by the first metering device 10 can be received twice within the preset time, and whether the charging current decreases twice consecutively is monitored.
Further, when the battery charge reaches the charge inflection point, the battery is about to be fully charged, and the situation that the charge current is continuously reduced occurs; in addition, in this embodiment, because charging device 100 sets up in the community, and community resident's sharing charging line, all charging device 100 all insert the management platform that charges, when community electric power is nervous, the management platform that charges will charge the regulation and control in order to restrict partial charging device's charging current in order to guarantee resident's power consumption, also can lead to the condition that charging current lasts to reduce. Therefore, the abnormal state of charge includes an almost fully charged state and a charge control state of the battery, and it is necessary to further determine the reason why the abnormal state of charge exists.
Further, the charging device 100 needs to further obtain the charged amount of the battery when the charging state is determined to be abnormal, that is, the charged amount when the charging current is detected to be reduced for the first time, and determines whether the charged amount reaches the warning electric quantity, if the charged amount is not lower than the warning electric quantity, it indicates that the charging current is continuously reduced due to that the vehicle battery is fully charged, at this time, the control module 30 generates a first charging reminding message, and sends the first charging reminding message to the charging application program of the user through the reminding module 50 to remind the user that the battery is about to be fully charged, and it is recommended to disconnect the charging connection to protect the vehicle battery.
Further, if the charging device 100 determines that the charged amount is lower than the pre-warning electric quantity, it needs to further determine whether the charging current is decreased because the battery is not fully charged due to the charging control of the charging management platform. At this time, the control module 30 generates an inquiry command and transmits the inquiry command to the inquiry module 40, and the inquiry module 40 sends inquiry information to the charging management platform to inquire the charging regulation and control state of the charging device 100. It can be understood that the query information at least includes the number information of the charging pile, and the charging management platform can query whether the charging device 100 is located in the current charging regulation and control sequence according to the number information after receiving the query information, and if the charging device 100 is located in the current charging regulation and control sequence, it indicates that the charging device 100 is in the charging regulation and control state; if the charging state is not in the current charging regulation sequence, it indicates that the charging device 100 is in the non-charging regulation state. The charging management platform queries the charging regulation information of the charging device 100 and then transmits the charging regulation information to the query module 40, and the query module 40 transmits the charging regulation information to the control module 30.
Further, if the charging device 100 is in the charging regulation state, the control module 30 generates a second charging reminding message, and sends the second charging reminding message to the charging application program of the user through the reminding module 50 to remind that the charging device 100 is in the charging regulation state, so that the charging current is reduced, and the user is reminded whether to replace the charging device to improve the charging efficiency.
Further, if it is monitored that the charging current of the charging device 100 continuously decreases, but the charging device 100 is in a non-charging regulation state, it is indicated that the remaining power of the charging device 100 during charging is high, and after a part of the power is charged, an early warning power is reached, that is, the battery is about to be fully charged, so that the control module 30 controls to generate a first charging reminding message, and sends the first charging reminding message to a charging application program of a user through the reminding module to remind that the battery is about to be fully charged, and it is recommended to disconnect the charging connection to protect the vehicle battery.
In summary, the charging device of the embodiment can record the pre-warning electric quantity reference value of the historical charging record and calculate the pre-warning electric quantity of the vehicle battery, analyze the charging state according to the conditions of the charging current, the charged amount and the pre-warning electric quantity in the subsequent charging process, and directly judge that the vehicle battery is fully charged and send out the first charging reminding notification when the charging current is continuously reduced and the charged amount is not less than the pre-warning electric quantity, without inquiring the charging regulation and control state; when the charging current is continuously reduced and the charged amount is smaller than the early warning electric quantity, the charging regulation and control state is inquired, a first charging reminding notice or a second charging reminding notice is sent according to the charging regulation and control state, a user can conveniently know the charging state, the charging connection is disconnected or the charging device is replaced according to the charging state, the vehicle battery is protected, and the charging convenience is improved.
The division of the modules in the charging device is merely for illustration, and in other embodiments, the charging device may be divided into different modules as needed to complete all or part of the functions of the charging device. The modules in the charging apparatus may be implemented in whole or in part by software, hardware, and a combination thereof.
