[0044] Figure 2 It is a partial structural diagram of the management and control system for the mobile charging station for electric vehicles described in the present invention. DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely expressed in combination with the drawings in the embodiments of the present invention. The embodiments expressed in this application are only part of the embodiments of the present invention, not all of them. According to the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without creative work are all within the protection scope of the present invention.

[0046] like Figure 1 As shown, a control method for a mobile charging station for electric vehicles according to the present invention includes:

[0047] The temperature transmitter samples the temperature value of the battery pack of the mobile charging station of the electric vehicle and transmits it to the control host. The power detection device samples the power value of the battery pack of the mobile charging station of the electric vehicle and transmits it to the control host. The control host transmits the collected temperature value and power value to the control center. The control center performs judgment based on the collected temperature value and power value. If the temperature value determines that the temperature exceeds the standard, the control center transmits an alarm command to the control host.

[0048] The control center performs a determination method based on the collected temperature value and power value, which runs on the control center and includes:

[0049] Step 1: The power value and temperature value of the battery pack of the mobile charging station of the electric vehicle during the charging and discharging period are respectively sampled in real time by receiving the power detection device and the temperature transmitter; and a queue A1 for storing the power values ​​arranged in the order of sampling time points and a queue A2 for storing the temperature values ​​are provided;

[0050] Step 2: Define the numerical critical value A3. A1 and A2 respectively receive the power value and temperature value transmitted by sampling synchronously. When the number of power value points (power value points are single power values) received by sampling in A1 is A3, the temperature over-regulation judgment is performed.

[0051] In a preferred but non-limiting embodiment of the present invention, Step 2 specifically includes:

[0052] Select the electric value point group A5 in which all the electric value in A1 is lower than the pre-defined critical value A4 and the temperature value points (the temperature value point is a single temperature value) with the same sampling time points as the respective electric value points in the electric value point group A5 to form the temperature value point group A6, and calculate the average of the temperature value points in the temperature value point group, which is defined as A7, and define the judgment value A8 and the judgment value queue A9 for registering the judgment value.

[0053] In a preferred but non-limiting embodiment of the present invention, A4=360 kWh.

[0054] In a preferred but non-limiting embodiment of the present invention, Step 2 specifically further comprises:

[0055] The following determinations are then performed:

[0056] When A10<A7<A11, and the minimum value in A6 is higher than A10, it indicates that the temperature value is out of specification, and A8=1 is registered;

[0057] In a preferred but non-limiting embodiment of the present invention, A10 and A11 are both predefined critical values, A10 = 0.003 degrees Celsius, A11 = 15 degrees Celsius. In the non-charging and discharging state, the sampled temperature value is the temperature value of the battery pack of the mobile charging station of the electric vehicle when it is not working. The temperature value of the battery pack of the mobile charging station of the electric vehicle when it is not working often needs to maintain a moderate level. When the sampled temperature value is lower than A11, it indicates that the temperature value of the battery pack of the mobile charging station of the electric vehicle is not in good condition, and is often not suitable for the next charge and discharge performance. When the sampled temperature value is lower than A10, it indicates that no significant temperature value is sampled at this time, and the temperature transmitter is often not assembled or not operating. At this time, it is not determined that the temperature exceeds the specification. The minimum value in A6 is higher than A10, which indicates that a significant temperature value is sampled when there is no charging and discharging condition. When A10 < A7 < A11, it means that the temperature measurement value exceeds the specification.

[0058] When A7 is higher than the predefined critical value A12, the temperature value is determined to be out of specification, and A8=1 is registered;

[0059] In a preferred but non-limiting embodiment of the present invention, A12 = 55 degrees Celsius. When the temperature value is too high, it also indicates that the temperature value point is out of specification, and the temperature value out-of-specification registration is performed.

[0060] Select the temperature points in A2 whose temperature values ​​are all lower than the predefined threshold value A11, and register the queue numbers of all the temperature points in the queue A2 for storing temperature values ​​in the group A13 according to the order of their queue numbers from low to high;

[0061] Calculate all adjacent partition quantities in A13, that is, take the quantity obtained by subtracting the previous element from each element in A13 as the adjacent partition quantity of the element, and register all adjacent partition quantities in group A14 in descending order of the serial number of the element where the adjacent partition quantity is located. When the number of adjacent partition quantities higher than one in A14 is higher than a pre-defined critical value A15, it is determined that the temperature value is out of specification, and A8=1 is registered at this time; A15 in the present invention can be determined according to specific requirements.

[0062] During the specific charge and discharge period, when the charge and discharge temperature bands fluctuate continuously, it indicates that the current temperature is out of specification. The present invention uses the serial numbers of the temperature value points to perform judgment, samples the serial numbers corresponding to the temperature value points whose overall temperatures are lower than A11, and calculates the adjacent differentiation values ​​between adjacent indexes. When the differentiation value is higher than one, it indicates that a pair of adjacent serial numbers are not continuous, that is, the temperature value fluctuates. If the number of differentiation values ​​higher than one is higher than A15, it is finally determined that the temperature value is out of specification.

[0063] If the temperature value point does not meet the following three conditions: A10<A7<A11, A7 is higher than the predefined critical value A12, and the number of adjacent partitions higher than one in A14 is higher than the predefined critical value A15, it indicates that the temperature value does not exceed the standard, and A8=heli is registered;

[0064] After each judgment is completed, the obtained A8 value is stored in the judgment value queue A9, and A1 and A2 are cleared.

[0065] Step 3: Define the iteration frequency critical value A16 and the over-standard iteration frequency critical value A17, repeatedly execute Step 1 to Step 2, continuously refresh A9, and when the number of A8 values ​​in A9 is A16, execute the alarm judgment, take out all A8 values ​​and judge, when the number of A8=1 is not less than A17, it is determined that the control center should send an alarm command to the control host, otherwise it will not be executed to let the control center send an alarm command to the control host. After the alarm judgment is reached, remove the first value in A9, and then execute the control method for the electric vehicle mobile charging station again.

[0066] like Figure 2 As shown, the management and control system for electric vehicle mobile charging stations according to the present invention includes:

[0067] The temperature transmitter, the power detection device and the GPRS module are all connected to the control host, and the control host is connected to the control center through the GPRS module.

The power detection device is arranged on the battery pack of the mobile charging station of the electric vehicle, and is used to sample the power value of the battery pack of the mobile charging station of the electric vehicle and transmit it to the control host. The control host is used to transmit the collected temperature value and power value to the control center, and the control center is used to perform judgment according to the collected temperature value and power value. If the temperature value determines that the temperature exceeds the specification, the control center transmits an alarm command to the control host;

[0068] The modules running on the control center include:

[0070] A determination module is used to define a numerical critical value A3. A1 and A2 respectively receive the electric quantity value and the temperature value transmitted by the sampling synchronously. When the number of points of the electric quantity value transmitted by the sampling in A1 is A3, the temperature exceeding the specification determination is performed.

[0072] In a preferred but non-limiting embodiment of the present invention, the judgment module is also used to select a power value point group A5 in which all power values ​​in A1 are lower than a pre-defined critical value A4 and a temperature value point group A6 formed by temperature value points corresponding to the same sampling time points as the respective power value points in the power value point group A5, and calculate the average of the temperature value points in the temperature value point group, which is defined as A7, and define a judgment value A8 and a judgment value queue A9 for registering the judgment value.

[0073] In a preferred but non-limiting embodiment of the present invention, the determination module is further used to perform the following determinations:

[0074] When A10<A7<A11, and the minimum value in A6 is higher than A10, it indicates that the temperature value is out of specification, and A8=1 is registered;

[0075] When A7 is higher than the predefined critical value A12, the temperature value is determined to be out of specification, and A8=1 is registered;

[0076] Select the temperature points in A2 whose temperature values ​​are all lower than the predefined threshold value A11, and register the queue numbers of all the temperature points in the queue A2 for storing temperature values ​​in the group A13 according to the order of their queue numbers from low to high;

[0077] Calculate all adjacent partition quantities in A13, that is, take the quantity obtained by subtracting the previous element from each element in A13 as the adjacent partition quantity of the element, and register all adjacent partition quantities in the group A14 in descending order of the sequence number of the element where the adjacent partition quantity is located. When the number of adjacent partition quantities higher than one in A14 exceeds a predefined critical value A15, it is determined that the temperature value exceeds the standard, and A8=1 is registered at this time;

[0078] If the temperature value point does not meet the following three conditions: A10<A7<A11, A7 is higher than the predefined critical value A12, and the number of adjacent partitions higher than one in A14 is higher than the predefined critical value A15, it indicates that the temperature value does not exceed the standard, and A8=heli is registered;

[0079] After each judgment is completed, the obtained A8 value is stored in the judgment value queue A9, and A1 and A2 are cleared.

[0080] In a preferred but non-limiting embodiment of the present invention, A10 and A11 are both pre-defined critical values, A10 = 0.003 degrees Celsius, A11 = 15 degrees Celsius.

[0081] The beneficial effects of the present invention are that, compared with the prior art, the technical effects of the present invention include:
