it should be noted that the control system 2 may be an electronic device such as a computer or a touch screen. In the working process of the adjusting system 3, when the internal temperature of the battery to be charged is higher than the first preset temperature and lower than the third preset temperature, the air with the preset temperature is introduced through the air inlet pipeline 103, the air with the preset temperature enters the air inlet pipeline 103 from the adjusting system 3 and then enters the charging cabinet body 1 from the air inlet pipeline 103, a good charging environment is provided for the heating phenomenon of the battery to be charged, the heat exchange capability in the charging cabinet body 1 is accelerated, the heat generated by the battery to be charged can be timely exchanged with the outside, the damage condition of the battery to be charged under the continuous abnormal temperature can be effectively reduced, and on the other hand, the explosion phenomenon of the battery to be charged in the charging process can be effectively avoided. The first preset temperature can be set by a user, and the third preset temperature is a critical temperature range of the surface of the battery to be charged reaching an ignition point, and only entering the critical temperature range means that the external material of the battery to be charged can be deformed and burnt, and the data can be acquired from a big data network. Because the battery is after full charge, even the situation that the spontaneous temperature rises in the twinkling of an eye still exists in the outage, when detecting the inside solution temperature or treating that the peripheral material temperature of rechargeable battery reaches the critical temperature scope of ignition point of detecting stick 105 or the charging cabinet body 1, let in the nitrogen gas of predetermineeing the temperature through admission line 103 this moment, the nitrogen gas of predetermineeing the temperature gets into admission line 103 from governing system 3, from admission line 103 reentrant charging cabinet body 1 in, because nitrogen gas is incombustible, this oxygen in the air can be isolated effectively, avoid the battery to carry out the possibility of burning continuously, and this nitrogen gas of predetermineeing the temperature also is favorable to cooling down the battery, continuously accelerate the heat exchange capacity of external environment and rechargeable battery.

A detection rod 105 and a humidity sensor are arranged inside the charging cabinet body 1, the detection rod 105 can communicate with a battery to be charged so as to obtain a temperature parameter change value inside the battery to be charged, and the humidity sensor obtains a humidity value inside the charging cabinet body 1 so as to control the starting of the adjusting system through the control system according to the humidity value;

The adjusting system 3 comprises a housing 301, a first air inlet 302 is arranged on the upper portion of the housing 301, a first cavity 303 is communicated with the lower portion of the first air inlet 302, at least two groups of second air inlets 304 are arranged in the first cavity 303, the second air inlets 304 are all connected with a control valve 305, a second cavity 306 is communicated with the lower portion of the control valve 305, and an adjusting rod 307 is further arranged below the control valve 305.

Further, in a preferred embodiment of the present invention, the control valves 305 are connected to a ventilation duct 309, so as to communicate with the second cavity 306 through the ventilation duct 309.

It should be noted that, firstly, gas enters the conditioning system 3 from the gas pump 104, and the gas pump 104 can at least emit two kinds of gas, one is air and the other is nitrogen, so that the gas enters the conditioning system 3, after entering the conditioning system 3, the gas enters from the first gas inlet 302, after entering the first cavity 303, because two sets of second gas inlets 304 are provided, one set of control valve 305 which is communicated with the second gas inlet 304 is opened, the air enters into the control valve 305 and then enters into the ventilation pipeline 309, and then the gas enters into the second cavity 306 from the ventilation pipeline 309; when nitrogen gas is input, one group of the opened control valves 305 is closed, and the other group of the control valves 305 is opened, so that the independent control of two states is realized, wherein one state is the condition that the internal temperature of the battery to be charged is higher than the first preset temperature and lower than the third preset temperature, and the condition is the condition of inputting air; the other state is the condition that the temperature reaches a third preset temperature range, and the condition is the state of inputting nitrogen; by means of independent control, when one group of control valves 305 fails, the other group can still work, and the gas conveyed by the whole regulating system 3 can be recycled, so that the use cost of the charging cabinet is reduced.

It should be noted that, the adjusting rod 307 is a telescopic structure, and for the conical design of the adjusting rod 307, because of the telescopic structure, the telescopic structure can be internally provided with a motor drive or an air cylinder for driving, and further, the length of the adjusting rod 307 is adjusted, so as to adjust the interval between the adjusting rod 307 and the housing 301, so as to adjust the air pressure of the input air, so as to adjust the amount of the air input into the charging cabinet 1 in unit time, so as to control the speed of heat exchange between the heat generated by the battery to be charged and the external environment, and can freely adjust according to the heat generated by the battery to be charged in the preset time, when the heat generated by the battery to be charged in the preset time is large, the amount of the air input into the charging cabinet 1 in unit time is large, otherwise, the amount of the air input in the preset time is small, so as to control the heat exchange capability according to the actual situation, the whole process intelligent control saves energy more compared with the prior art.

Further, in a preferred embodiment of the present invention, a movable link 308 is further disposed below the housing 301, and the movable link 308 and the housing 301 can generate a relative displacement.

Further, in a preferred embodiment of the present invention, a third air inlet 310 is disposed above the movable link 308, and the third air inlet 310 is provided with a screw thread for connecting the air inlet pipe 103 through the screw thread.

It should be noted that, the position of the movable connecting rod 308 and the housing 301 is adjusted by using the relative movement between the movable connecting rod 308 and the housing 301, so as to adjust the gap between the movable connecting rod 308 and the housing 301, and further adjust the amount of gas input in a unit time in the left-right direction, so as to intelligently regulate and control the heat exchange efficiency between the gas and the battery to be charged, thereby ensuring that the battery in the charging cabinet always maintains a certain heat exchange capacity with the outside during the charging process, and further effectively reducing the combustion or explosion phenomenon generated during the charging process of the battery.

Further, in a preferred embodiment of the present invention, the control system can control the air intake amount of the air pump 104 according to the temperature parameter variation value obtained by the detection rod 105, and if the temperature parameter variation value is greater than a first preset temperature value, the adjustment system 3 is started.

It should be noted that, because two sets of vent pipes are arranged in the regulating system 3, one set of vent pipe conveys air, the other vent pipe conveys nitrogen, a temperature sensor is arranged inside the charging cabinet, when the temperature sensor detects that the temperature value inside the battery is too high (reaches the first preset temperature range set by the temperature sensor), the regulating system 3 is started at the moment, and the air is utilized to cool the battery to be charged at the moment, so that the cost is lower compared with the prior art.

Further, in a preferred embodiment of the present invention, a temperature sensor is further disposed in the charging cabinet 1, the temperature sensor can acquire a temperature value in the charging cabinet 1, and if the temperature value in the charging cabinet 1 is greater than a second preset temperature value, the adjusting system 3 is started.

It should be noted that, the second preset temperature value is a temperature value corresponding to a preset capacitance characteristic parameter value corresponding to the battery to be charged, and when the second preset temperature value exceeds the temperature value, the adjusting system 3 is started, so that the probability of a fault occurring when the battery to be charged of the charging cabinet is charged in summer can be effectively reduced, the current amount of leakage current can be effectively reduced, the temperature increase range of the battery to be charged in the charging process can be reduced, and the probability of a fault occurring when the battery to be charged is charged in an environment with abnormal temperature can be reduced.

Further, in a preferred embodiment of the present invention, a plurality of spacers 106 are disposed on two sides in the charging cabinet 1, the spacers 106 are disposed with a plurality of through holes, and an insulating plate 107 is disposed between the spacers 106 on the two sides.

Further, in a preferred embodiment of the present invention, a predetermined gap is left between the insulating plates 107, so that the positive and negative electrodes of the battery to be charged can contact with the detection rod 105, and a first sensor is disposed in the predetermined gap between the insulating plates 107, so as to detect the leakage current through the first sensor.

It should be noted that, after the gas comes out from the air inlet duct 103, the gas enters into the charging cabinet 1, and due to the arrangement of the partition plates 106 which are linearly arranged and the plurality of through holes arranged on the partition plates 106, the gas can act on the surface of the battery to be charged from the through holes of the partition plate on the left side, enters from the through holes of the partition plate on the right side, and flows back from the through holes of the partition plate on the right side, so as to form a backflow system, which can prevent high-speed airflow from directly acting on the battery during charging, decompose the airflow into a plurality of groups of airflows, and is beneficial to uniform heat dissipation during charging; on the other hand, because two sets of insulating plates 107 are arranged in parallel, and the detecting rod 105 is arranged in the gap formed by the two sets of insulating plates 107, the gas in the through hole can be effectively prevented from directly acting on the detecting rod 105, and the detecting rod 105 is arranged at the anode and the cathode of the battery to be charged, so that on one hand, charging is carried out, and on the other hand, communication with internal components of the battery to be charged is carried out, such as a temperature sensor, a liquid pressure sensor and the like in the battery to be charged, so that internal temperature parameters, pressure parameters and the like can be obtained.

It should be noted that the battery to be charged may be a battery of an electric vehicle, an automobile battery, a new energy battery, or the like. On the other hand, in the rated temperature range, when the temperature is increased, the value of the dissipation factor is reduced, the resistance value is reduced, the leakage current is increased along with the increase of the temperature, the increase of the leakage current promotes the increase of the temperature of the capacitor, a vicious circle is formed, and the fault occurrence probability is increased. When the first sensor detects that the leakage current of the detection rod exceeds a preset leakage current value, the adjusting system 3 is started at the moment, heat is uniformly dissipated in the charging process, so that the leakage current can be effectively reduced, the damage rate of internal components of the battery in the charging process is reduced, and the probability of battery failure in the charging process is reduced.

The invention also provides a control method of the battery charging cabinet based on the Internet of things, which is applied to any battery charging cabinet based on the Internet of things and comprises the following steps:

s102, acquiring a temperature value in a battery to be charged through a detection rod to generate first temperature information;

s104, judging whether the first temperature information is larger than a first preset temperature value or not, if so, starting the adjusting system through a control system, wherein one group of control valves is opened;

s106, starting the air pump through the control system, introducing air with a preset temperature, continuously acquiring a temperature value inside the battery to be charged after the air pump is started, and generating second temperature information;

and S108, judging whether the second temperature information is larger than a third preset temperature value or not, if so, closing the opened control valves, opening the other group of control valves, and converting the air introduced with the preset temperature into nitrogen introduced with the preset temperature by using the air pump.

It should be noted that two sets of air ducts are arranged in the regulating system, one set of air duct conveys air, the other air duct conveys nitrogen, a temperature sensor is arranged in the charging cabinet, when the temperature sensor detects that the temperature value in the battery is too high (reaches a first preset temperature range set by the temperature sensor), the regulating system is started, and at the moment, the air is used for cooling the battery to be charged, so that the cost is lower. When the temperature sensor exceeds the third preset temperature range, the adjusting mechanism is started, nitrogen in another pipeline is sprayed out, so that the combustion source can be blocked in time, the rechargeable battery is prevented from burning, the charging cabinet is protected, the whole adjusting system can be recycled, and the maintenance cost is reduced.

s202, acquiring capacitance characteristic parameter values of all temperatures through a big data network, and establishing a capacitance characteristic parameter value database based on the capacitance characteristic parameter values;

s204, acquiring an environmental temperature value inside the battery charging cabinet through a temperature sensor, and generating third temperature information;

s206, importing the third temperature information into the capacitance characteristic parameter value database to obtain a real-time capacitance characteristic parameter value under the temperature;

s208, comparing the real-time capacitance characteristic parameter value with a preset capacitance characteristic parameter value to obtain a deviation ratio;

and S210, judging whether the deviation rate is greater than a preset deviation rate, and if so, starting an adjusting system.

It should be noted that, since the ambient temperature in summer has a very important influence on the occurrence of a fault, the battery to be charged is equivalent to a capacitor, and for the capacitor, the temperature-dependent capacitance characteristic parameter values include a dissipation factor, impedance and leakage current. Within the rated temperature range, when the temperature is increased, the value of the dissipation factor is reduced, the resistance value is reduced, the leakage current is increased along with the increase of the temperature, the increase of the leakage current promotes the increase of the temperature of the capacitor, a vicious circle is formed, and the fault occurrence probability is increased. The capacitor operating voltage will also affect the operating leakage current of the capacitor. When the working voltage of the capacitor is greater than the rated voltage, the working leakage current is greatly increased. Meanwhile, the capacitive reactance of the capacitor is in direct proportion to the frequency of the working voltage. When the harmonic content in the voltage applied to the two ends of the capacitor is higher, due to the characteristic that the capacitor is communicated with alternating current, the high-frequency capacitive reactance is very low, and the higher harmonic voltage passes through the capacitor, so that the higher harmonic current is increased, the waveforms of the current and the voltage are greatly distorted, the temperature rise is further increased, and the probability of fault occurrence is increased. Meanwhile, the temperature rise is further increased, and the probability of fault occurrence is increased. Therefore, the environmental temperature information in the real-time charging cabinet body can be acquired through the temperature sensor, the capacitance characteristic parameter value under the temperature information is extracted from the database, at the moment, the adjusting system is started to control the environment, the probability of faults of the battery to be charged of the charging cabinet in summer when charging can be effectively reduced, the current amount of leakage current can be effectively reduced, the temperature rise amplitude of the charging battery in the charging process is reduced, and the probability of faults of the battery to be charged in the environment with abnormal temperature is reduced.

In addition, the method can further comprise the following steps:

acquiring battery electric quantity error values at various temperatures through a big data network, and establishing a battery electric quantity error value database based on the battery electric quantity error values;

acquiring an environmental temperature value in a current battery charging cabinet, and importing the environmental temperature value into the battery electric quantity error value database to obtain a battery electric quantity error value under the environmental temperature value;

acquiring a battery electric quantity value displayed in a current control system, and calculating an actual battery electric quantity value based on the battery electric quantity value and a battery electric quantity error value;

and obtaining the actual charging cost according to the battery electric quantity value, and transmitting the actual charging cost to a control system for display.

It should be noted that, because components inside the charging cabinet are prone to generate different temperature drifts at different temperatures, the components affected by temperature, such as the reference voltage of the internal metering chip, the reference voltage regulator tube, the metal film resistor and the like, all have corresponding temperature coefficients, and the magnitude of the temperature coefficients changes with the change of temperature, which causes different accumulated errors of the system obtained during measurement, thereby causing different indication errors; the charge capacity is the cumulative amount of power and time. The real-time power is obtained by a voltage sampler and a current sampler of a metering unit of the charging cabinet through a multiplier, and the accuracy of the voltage sampler and the accuracy of the current sampler are influenced by the sampling bit number and the internal crystal oscillator under the working temperature condition. The sampler can generate nonlinear errors at different working temperatures, and meanwhile, the internal crystal oscillator frequency is the temperature sensitive quantity, so that the errors of all the parts have certain influence on the indication value error of the accumulated value of the charging electric quantity at different temperatures. The error value of the battery electric quantity under different temperatures can be extracted from the big data network, so that the actual cost needed after the charging of the charging pile is completed is obtained, the actual electricity consumption can be charged according to the electricity consumption condition, the charging can be calculated by a supplier, and the error compensation value of the battery electric quantity is generated by utilizing the influence of the temperature on the battery electric quantity, so that the actual electricity consumption is calculated, the rights and interests of consumers and the rights and interests of the supplier are favorably ensured, if the used charging quantity of an aged battery exceeds the actual charging quantity, and if the influence of the temperature on the error value of the battery electric quantity causes multi-charging in the charging process, the method can effectively avoid the occurrence of the events.

In summary, on one hand, the regulating system of the present invention is provided with two sets of air ducts, one set of air duct transports air, the other air duct transports nitrogen, a temperature sensor is disposed inside the charging cabinet, when the temperature sensor detects that the temperature value inside the battery is too high (reaches a first preset temperature range set by the temperature sensor), the regulating system is started, and at this time, the air is used to cool the battery to be charged, which results in lower cost. When the temperature sensor exceeds the third preset temperature range, the adjusting mechanism is started, nitrogen in another pipeline is sprayed out, so that the combustion source can be blocked in time, the rechargeable battery is prevented from burning, the charging cabinet is protected, the whole adjusting system can be recycled, and the maintenance cost is reduced.

On the other hand, when the internal heat exchange is accelerated, the humidity sensor can be arranged in the charging cabinet, the adjusting system is started, so that the charging process can be influenced due to the humidity relation in the charging process, the condition that the current leakage exists in the charging process in foggy weather can be avoided, the air cooling system is started to dry the inside of the charging cabinet, and the safety of the charging cabinet in the charging process of the battery to be charged is effectively guaranteed.

On the other hand, the temperature sensor is arranged in the charging cabinet body, when the temperature sensor detects that the temperature in the power conversion cabinet exceeds the preset temperature value, the adjusting system is started, the phenomenon that the current leakage current is too high due to too high temperature in summer can be effectively avoided, the temperature rise of the battery to be charged is further reduced, and therefore the probability of faults of the battery to be charged in the charging process is reduced.
