The frequent use of electric forklifts and electric tractors requires frequent charging. Manual charging is mostly adopted during charging, and manual recording is mostly used for charging records, which is time-consuming, laborious and inefficient. Some forklifts and electric tractors are often forgotten if they are idle for a period of time, and there is a risk of battery damage due to untimely charging. At the same time, the charging data recorded manually is difficult to ensure data accuracy, which is not convenient for effectively mastering the real charging status of electric forklifts and electric tractors. The existing charging detection technologies are difficult to meet the above requirements and have a relatively high cost. Content of the Utility Model

[0017] The present utility model will be further described below in conjunction with the drawings and embodiments. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0018] As shown Figure 1 in the figure, a charging intelligent monitoring device includes a control cabinet 1 and a charger 9 for connecting with an electric vehicle. The charger 9 is specifically a charging connector for charging an electric forklift and a tractor. The control cabinet 1 includes a controller 3 and a touch screen 2 electrically connected to the controller 3. The touch screen 2 is specifically connected to the controller 3 through a network cable. Among them, the controller 3 is a PLC controller. The control cabinet 1 further includes a control cabinet power supply 4, and the control cabinet power supply 4 is electrically connected to the touch screen 2 and the controller 3 for supplying power to the touch screen 2 and the controller 3.

[0019] The charging intelligent monitoring device further includes a barcode scanner 5 for scanning the barcode of the electric vehicle. The barcode scanner 5 is communicatively connected to the touch screen 2. The touch screen 2 sends the barcode information of the electric vehicle to be charged to the controller 3. The controller 3 records the charging time data of the electric vehicle and stores the barcode information and charging time data of the electric vehicle in an associated manner in a storage unit. A control program is written in advance in the controller 3, and a touch screen program is written on the touch screen 2. The license plate code of the electric vehicle to be monitored and the storage time of the charging record are set in the program. The license plate code is associated with the barcode data of the electric vehicle. The charging record is the charging time data of each electric vehicle. The operator can view the charging records of each electric vehicle through the touch screen 2, which is convenient for tracing.

[0020] The controller 3 includes a timing unit. The controller 3 sets the maximum charging time interval of the vehicle in the program. The touch screen 2 includes an alarm unit. When any electric vehicle starts charging, the timing unit starts timing. When the vehicle charges again, the timing is cleared and starts again. If the timing exceeds the maximum charging interval time set by the controller 3 and the vehicle does not charge again, the alarm unit alarms, and the touch screen 2 displays the vehicle information of the electric vehicle that exceeds the maximum charging interval time, reminding the operator to charge in time, thereby avoiding damage to the battery caused by over-discharge due to long-term non-charging caused by vehicle idleness, forgetting to charge, etc., and ensuring the safety and reliability of the electric forklift and the tractor.

[0021] Specifically, the charger 9 is electrically connected to a charging power supply 6. An ammeter 8 is electrically connected between the charger 9 and the charging power supply 6. The ammeter 8 is electrically connected to the controller 3. The ammeter 8 can monitor the charging current between the charging power supply 6 and the charger 9. The charging power supply 6 is specifically a 220V AC power supply.

[0022] Further, a charging control switch 7 is electrically connected between the charger 9 and the charging power supply 6. The charging control switch 7 is a normally closed switch. When the charging current is higher or lower than the charging current range set by the controller 3, the controller 3 controls the charging control switch 7 to open.

[0023] Specifically, the maximum charging current and the minimum charging current are set in the program of the controller 3. When the charging current is higher than the charging current range set by the controller 3, that is, when the charging current is higher than the maximum charging current, the charging current is too large at this time. The controller 3 sends an alarm signal to the alarm unit, and the alarm unit gives an alarm. At the same time, to avoid damaging the battery, the charging control switch 7 is disconnected to stop charging, realizing automatic power-off protection. When the charging current is lower than the charging current range set by the controller 3, that is, when the charging current is lower than the minimum charging current, the charging current drops to a constant value at this time, and the battery of the electric vehicle is fully charged. The charging control switch 7 is disconnected, and the charging is completed, realizing automatic power-off.

[0024] Further preferably, the barcode scanner 5 is a wireless barcode scanner, and the wireless barcode scanner is wirelessly communicatively connected to the touch screen 2. Specifically, the touch screen 2 is provided with a USB interface, and the communication interface of the wireless barcode scanner is installed in the USB interface, with stable data transmission and more convenient use.

[0025] The charging intelligent monitoring device of the present utility model associates and stores the barcode information of the electric vehicle scanned by the barcode scanner with the charging time by setting a touch screen and a controller in the control cabinet, which is convenient for viewing and tracing. At the same time, the controller is provided with a timing unit, and the touch screen displays the vehicle information of the electric vehicle exceeding the maximum charging interval time and gives an alarm through the alarm unit, so as to automatically remind when the idle vehicle has not been charged for a long time, ensuring the safety and reliability of the electric vehicle.

These are only illustrative examples, and the protection scope of the present utility model is defined by the claims.
