In the production and assembly process of the overhead working truck, the charging machine is required to be subjected to complex charging parameter configuration so as to adapt to batteries of different types. For each type of battery, appropriate charging parameters, such as charging power, charging capacity, charging time, etc., need to be configured for the charger.
For different lead-acid batteries, when the lead-acid batteries leave the factory, the charging parameters of the lead-acid batteries can be preconfigured in the electronic tags of the lead-acid batteries, so that a user can conveniently carry out parameter configuration on the charger by reading the charging parameters in the electronic tags of the lead-acid batteries and then according to the read charging parameters. This type of approach requires a large amount of parameter information to be configured in advance in the electronic tag of the lead-acid battery and has high requirements for the reading process.
The embodiment provides a charging device installed on a vehicle terminal, which can rapidly complete parameter configuration of a charger according to an electronic tag of a lead-acid battery, has low cost and high reliability.
As shown in fig. 1, in one embodiment, the charging device includes an ac input interface 110, a dc output interface 120, a radio frequency identification technology (Radio Frequency Identification, RFID) reader 130, a CAN communication unit 140, and a power conversion unit 150.
In the practical application process, the ac input interface 110 is connected to the dc output interface 120 via the power conversion unit 150, the rfid reader 130 is connected to the CAN communication unit 140, and the power conversion unit 150 is connected to the CAN communication unit 140.
Specifically, the ac input interface 110 is connected to a preset power source, and is configured to receive a preset ac electrical signal. The dc output interface 120 is connected to the target lead-acid battery 200 for outputting a target dc electrical signal to the target lead-acid battery 200. The RFID reader 130 is used to read the charging code from the electronic tag of the target lead-acid battery 200. And the CAN communication unit 140 is connected with the RFID reader 130, and the CAN communication unit 140 is used for receiving the charging code number read by the RFID reader 130. The power conversion unit 150 is connected to the ac input interface 110 and the dc output interface 120, respectively, and is configured to convert a preset ac electrical signal into a target dc electrical signal according to the charging code.
In a specific embodiment, the preset power source may be a commercial power source or other ac power source, capable of providing a preset ac signal for stabilizing the charging voltage of the target lead-acid battery 200.
The target lead-acid battery 200 is a lead-acid battery having an electronic tag with a charging code stored therein. Wherein, the charging codes can be A01, A02, B01 or B02, and each charging code corresponds to a charging rule. Specifically, the charging rule includes execution parameters such as charging time, charging power, charging capacity, charging phase, phase transition point, and the like. In a specific embodiment, the charging code number may be composed of a three-digit number, or may be adaptively configured according to the needs of the actual application scenario.
Specifically, the corresponding relation between the charging code number and the charging rule is stored in a flash memory connected with the controller, and only the charging code number is stored in an electronic tag of the target lead-acid battery.
In the actual application process, the RFID reader 130 approaches to the electronic tag of the target lead-acid battery 200, namely the charging code stored in the electronic tag can be acquired based on the interaction of radio frequency signals. After the RFID reader 130 obtains the charging code, the charging code is transmitted to the power conversion unit 150 through the CAN communication unit 140 and a preset CAN communication protocol, and the power conversion unit 150 performs alternating current-direct current (AC-DC) conversion and voltage regulation processing on the preset alternating current signal according to a charging rule and a charging parameter corresponding to the charging code read by the RFID reader 130, so as to obtain a target voltage signal for charging the target lead-acid battery.
In a specific embodiment, the power conversion unit 150 should at least include an AC-DC conversion circuit and a power conditioning circuit. The AC-DC conversion circuit is used for converting an alternating current electric signal into a direct current electric signal, charging the lead-acid battery, and the power regulation circuit is used for converting the voltage value of the voltage signal into a preset voltage value, so that a target voltage signal with the preset voltage value is obtained. For example, the power conversion unit 150 may regulate 380V ac voltage to 220V dc voltage.

In a specific embodiment, the controller 160 is configured to parse the charging code to obtain a charging control parameter, and control the power conversion unit 150 to convert the preset ac signal into the target dc signal based on the charging control parameter.
Specifically, the corresponding relationship between the charging code number and the charging rule and the charging parameter may be stored in the memory connected to the controller 160 in a program manner, after receiving the charging code number acquired by the CAN communication unit 140, the controller 160 may analyze the charging code number according to a preset program to finally obtain the charging rule and the charging parameter corresponding to the charging code number,
For example, the charging code B02 corresponds to a charging curve, wherein the charging curve includes 3 charging phases, namely, charging phase 1, charging phase 2 and charging phase 3. The charging stage 1 is charged in accordance with the charging voltage 1, the charging current 1, the charging time 1, the off-voltage 1, and the off-capacitance 1. The charging stage 2 is charged in accordance with the charging voltage 2, the charging current 2, the charging time 2, the off-voltage 2, and the off-capacitance 2. The charging stage 3 is charged in accordance with the charging voltage 3, the charging current 3, the charging time 3, the off-voltage 3, and the off-capacitance 3. The specific values of the different charging stages may be the same or different, and may be adaptively configured according to the actual application scenario, which is not specifically limited herein.
It should be appreciated that the number of charging codes may be configured according to the actual application scenario, so as to include the charging parameters of the common battery type. The analysis program of each charging code is stored in the memory connected to the controller 160, and it should be understood that the corresponding relationship between the charging code and the charging rule may be stored in the form of a parameter list, which is not limited in the number of charging codes and the storage manner of the charging codes in this embodiment.
In the practical application process, the controller 160 of each charging device is configured with an original charging code, and after receiving the new charging code based on the CAN communication unit 140, the controller 160 automatically replaces the original charging code according to the new charging code, and analyzes according to the new charging code to obtain a corresponding charging control parameter.
The specific content of the charging control parameter corresponds to a charging curve represented by a charging code, which is not described herein.
In one embodiment, as shown in fig. 3, the charging device further includes a USB interface 170, and the controller 160 is connected to the USB interface 170, and is configured to connect to the preset configuration terminal 300 through the USB interface 170.
Specifically, the configuration terminal 300 may be a computer, a mobile terminal, a tablet computer, or a wearable terminal, and the type of the configuration terminal 300 is not limited in this embodiment.
The user may connect the controller 160 through the configuration terminal 300 and the USB interface 170 to change a program or original parameters stored in the controller 160.
In one embodiment, upon receiving the configuration signal sent by the preset configuration terminal 300, the controller 160 modifies the charging code in the electronic tag of the target lead-acid battery 200 according to the configuration signal via the CAN communication unit 140 and the RFID reader 130.
Specifically, in some application scenarios, the target lead-acid battery 200 may need to change the charging rule and the charging parameters due to incorrect initial parameter configuration or usage loss, and the user may directly modify the charging code in the electronic tag of the target lead-acid battery 200 based on the charging device provided in this embodiment, so as to avoid damage to the target lead-acid battery 200 caused by mismatching of the charging parameters.
In one embodiment, as shown in fig. 4, the charging device further includes a housing, in which a receiving space is included, and the power conversion unit 150 and the controller 160 are both installed in the receiving space.

The LED display 182 is coupled to the controller 160 for displaying the charge number and state of charge of the target lead-acid battery.
In a specific embodiment, the charging states include a charging state and an uncharged state, and in the practical application process, the charging state may be displayed in a charging state column in the LED display screen 182, or the charging state of the charging device of the embodiment may be displayed only through one charging signal lamp.
Specifically, as shown in fig. 7, an LED display 182 may be mounted on a surface of a lower case of the charging device.

The alarm 184 is connected to the controller 160, and when the temperature acquired by the temperature sensor 183 exceeds a preset temperature value, the controller 160 controls the alarm 184 to alarm.
In a specific embodiment, when the temperature detected by the temperature sensor 183 continuously rises, the control power of the heat radiation fan 181 may be increased by the controller 160 until the heat radiation fan 181 radiates heat at the maximum power. When the temperature detected by the temperature sensor 183 drops, the control power of the cooling fan 181 may be reduced by the controller 160, keeping the temperature of the dc output interface 120 of the charging device within a preset temperature range.
