[0033] like Figure 1 As shown, this utility model provides a centralized charging control device for electric vehicles, including a control system 1 and multiple charging sockets 2, as well as multiple temperature acquisition units 3 and alarm units 8 connected to the control system 1, and also includes a power supply circuit 4, an interface circuit 5 and a power control unit 6.

[0034] Multiple temperature acquisition units 3 are respectively in contact with the outer casing of multiple electric vehicle batteries to collect battery temperature data;

[0035] The multiple charging sockets 2 are respectively connected to the plugs of multiple electric vehicle batteries for charging the batteries;

[0036] When the current data acquired by the control system 1 exceeds a preset threshold, the alarm unit 8 is controlled to issue an alarm signal and a stop charging signal is sent to the charging socket 2.

[0037] The control system 1 is used to collect and monitor the temperature data. When the temperature data exceeds a preset temperature threshold, it sends a stop charging signal to the charging socket 2.

[0040] The power control unit 6 is connected to the current monitoring unit 7, which is connected to the charging socket 2 and the control system 1. The current monitoring unit 7 is used to acquire the current data of the charging socket 2 when it is working and upload it to the control system 1.

[0041] As a further explanation of this utility model, each of the temperature acquisition units 3 is connected to a temperature sensor 31, and the temperature sensor 31 is in contact with the battery casing.

[0042] As a further explanation of this utility model, the interface circuit 5 is connected to the monitoring terminal 9, which is used to set charging parameters.

[0043] As a further explanation of the present invention, the control system 1 includes a controller 11 and a control panel 12 connected to the controller 11;

[0044] The control panel 12 is used to display current data and alarm signals.

[0045] In this embodiment, the controller 12 is preferably a microcontroller.

[0046] The control panel 12 is used to display relevant parameters and parameter settings. The microcontroller is used to process the data collected by the temperature acquisition unit 3 and the current monitoring unit 7. When the collected data is abnormal, it issues power-off and alarm commands. At the same time, the microcontroller's operating parameters and status are transmitted to the monitoring terminal 9 through the interface circuit 5. The monitoring terminal 9 can also set parameters.

[0047] The parameter mentioned here can be a temperature parameter: this is a value directly measured by the temperature acquisition unit, such as the temperature inside or outside the equipment. This data is crucial for ensuring the equipment operates within a safe operating temperature range.

[0048] Current parameters: The current monitoring unit is responsible for monitoring the current intensity passing through the circuit. This helps prevent overload conditions and protects the equipment from damage.

[0049] Threshold settings: To enable the system to respond according to actual conditions, some thresholds are usually preset. For example, when the detected temperature exceeds a certain preset maximum value or falls below a certain minimum value, the system will take appropriate measures.

[0050] Alarm conditions: In addition to simple thresholds, more complex alarm logic can be defined. For example, an alarm can be triggered when abnormally high or abnormally low readings are detected consecutively within a specific time period.

[0051] System status: This includes the system's operating mode, such as normal operation, standby, fault, etc., the working status of each component, whether it is online, and whether there are error reports.

[0052] Control commands: The monitoring terminal can send various commands to the control system to adjust its operation. For example, changing the target temperature or adjusting the current limit.

[0053] Historical data: Although not real-time parameters, the system may record temperature and current change trends over a period of time, which is very useful for subsequent analysis and troubleshooting.

[0054] Security settings: To prevent unauthorized operations, the system may also include parameters related to access control, password protection, and other functions.

[0055] As a further explanation of this utility model, the control system 1 sends a stop charging signal to the power control unit 6, and the power control unit 6 controls the charging socket 2 to stop charging.

[0056] As a further explanation of this utility model, the charging socket 2 is equipped with a manually controlled start charging button and a stop charging button, which are used to manually control whether the charging socket 2 is charging. The start charging button and the stop charging button are connected to the power control unit 6.

[0057] As a further explanation of this utility model, the alarm unit 8 is an audible and visual alarm.

[0058] When in use, connect one end of the electric tricycle charger to the battery, insert the plug-side into charging socket 2, and ensure the temperature sensor 31 makes effective contact with the battery casing to accurately reflect battery temperature changes. Simultaneously, input the charging time, upper limit temperature of temperature sensor 31, and upper limit charging current on the control panel 12. Press the start button on charging socket 2; the power control unit 6 will activate the electrical components of charging socket 2, initiating charging. The current monitoring unit 7 and temperature acquisition unit 3 monitor the charging current and battery temperature in real time. If the set charging time has not been reached, press the stop button on charging socket 2 at any time. The parameter settings and start / stop operations can also be performed on the monitoring terminal 9. If another electric vehicle is being charged, insert its charger plug into charging socket 2, ensuring the temperature sensor 31 makes effective contact with the battery casing. Other operations are the same as for the first vehicle. This controller can control the charging of multiple electric vehicles.

[0059] After the electric vehicle charging begins, the current monitoring unit 7 monitors the charging current of each charging socket in real time, and displays the results on the control screen 12 and the monitoring terminal 9. When the charging current of a certain charging socket 2 exceeds the set upper limit, the microcontroller issues a stop charging command, the power control unit 6 executes the command, stops the power supply to the charging socket 2, the audible and visual alarm sounds, and the alarm information is displayed on the control screen 12 and the monitoring terminal 9 to prompt maintenance personnel to find out the cause.

[0060] After the electric vehicle charging begins, the temperature acquisition unit 31 monitors the battery charging temperature corresponding to each charging socket 2 in real time. When it is found that the battery charging temperature corresponding to a certain charging socket 2 exceeds the set temperature, the microcontroller issues a stop charging command, the power control unit 6 executes the command to stop the power supply to the charging socket, the audible and visual alarm sounds, and the alarm information is displayed on the control screen 12 and the monitoring terminal 9 to prompt maintenance personnel to find out the cause.
