In addition, especially in the charging process, since the communication rod 108 can communicate with each component inside the battery to be charged, if the current signal is abnormal in the charging process, the abnormal phenomenon may be that the current signal is not detected within a preset time, which indicates that the current communication system inside the battery to be charged is faulty, and such a fault point easily causes that the internal current change condition cannot be detected in the charging process of the battery, so that the possibility of burning out the battery easily exists, and the detection can be increased to effectively recycle the battery to be charged with various fault points.

On the other hand, the battery that has been replaced in the replacement cycle may also be replaced, the number of times of charging the battery to be charged is obtained by using the communication rod 108, and since the number of times of charging exceeds the preset number of times set by the manufacturer, the replacement mechanism 2 may also be activated to replace the battery at this time.

It should be noted that, a first sensor is arranged on the push block 106, the first sensor may be a pressure sensor, since the communication rod 108 can communicate with the battery to be charged, the battery can obtain the critical pressure value of the external material type of the battery to be charged corresponding to the critical pressure value of the generation plastic deformation through the big data network at the moment, so that the thrust of the push block 106 does not exceed the critical pressure value of the generation plastic deformation, the thrust can be obtained by the pressure sensor, and the thrust can be regulated and controlled in real time, so that in the positioning process, the damage of the battery to be charged is avoided, and the mechanical damage in the positioning process is avoided.

It should be noted that, in the charging process, the first cylinder 105 can be used to drive the push block 106 so that the battery to be charged can be fixed, and thus, when a foreign object collides with the power exchange cabinet, the communication rod 108 is prevented from moving in a dislocation manner, so that the charging process is prevented from being affected.

As shown in fig. 4 and fig. 5, in a preferred embodiment of the present invention, the clamping mechanism 205 includes a sheet metal part 401 disposed on the second moving block 204, the sheet metal part 401 is disposed on a supporting plate 402, fixing blocks 403 are disposed around the supporting plate 402, the fixing blocks 403 are connected to a rotating block 404, and the rotating block 404 is driven by a second cylinder 405 to rotate.

Further, in a preferred embodiment of the present invention, the

rotating blocks

404 and 404 are connected by a rectangular block 406 in one direction, one side of the rectangular block 406 is penetrated by a plurality of T-shaped posts 407, and a plurality of L-shaped posts 408 are disposed on one side of the rectangular block 406.

It should be noted that, the second cylinder 405 is used to drive the rotating block 406, so that the T-shaped pillar 407 and the L-shaped pillar 408 on the rectangular block 406 are in contact with the battery to be charged, in the contact process, the plane where the positive and negative electrodes of the battery to be charged are located is taken as the upper surface, the T-shaped pillar 407 is in contact with the side surface of the battery to be charged, and the L-shaped pillar 408 can be joined with the front surface of the battery to be charged.

As shown in fig. 8, a second aspect of the present invention provides a method for controlling a battery changing cabinet with an automatic battery changing function, which is applied to any one of the battery changing cabinets with an automatic battery changing function, and includes the following steps:

s102, acquiring a parameter value of a battery to be charged within a preset time; the parameter values comprise a pressure parameter value and a temperature change parameter value inside the battery;

s104, calculating a parameter change rate based on the parameter value of the battery to be charged within the preset time;

s106, judging whether the parameter change rate is smaller than a preset parameter change rate threshold value or not;

and S108, if the voltage is smaller than the preset voltage, generating a starting signal, and transmitting the starting signal to the control terminal of the battery power exchange cabinet.

It should be noted that many factors of fire explosion of lithium batteries are involved, but the main reasons are high temperature and high pressure inside the batteries, which are directly related to heat generation factors. The heat generation factors inside the battery are numerous, and if the heat generation rate inside the lithium battery is greater than the heat dissipation rate, the reaction temperature in the system will rise continuously. The result may be two extremes: the temperature of the reaction mass reaches its ignition temperature and a fire occurs; because the lithium battery is a closed system, the reaction speed is accelerated along with the temperature rise in the system, and the vapor pressure of reactants rises rapidly. Meanwhile, a certain amount of gas is generated by decomposition of the active material and reaction of the active material and the electrolyte, and the internal pressure of the battery can be rapidly increased to cause explosion of the battery under the condition of lack of protection of a safety valve or failure of the safety valve. The communication rod can communicate with the parts in the battery to be charged, whether the internal control valve is damaged or not is determined by determining whether the parameter change rate is smaller than a preset parameter change rate threshold value or not in the charging process, when the parameter change rate is smaller than the preset parameter change rate threshold value, the safety valve has a certain range value in design, and when the range value is smaller than the preset range change value in preset time, the internal safety valve is damaged, the event possibly causes explosion and belongs to the safety valve fault.

As shown in fig. 9, in a preferred embodiment of the present invention, the method for controlling a battery changing cabinet with an automatic changing function further includes the following steps:

s202, acquiring a communication signal fed back by the communication rod;

s204, judging whether the battery power-exchanging cabinet control terminal can receive a communication signal fed back by the communication rod within a preset time;

s206, if not, indicating that the battery to be charged is in a fault state;

s208, if yes, obtaining the discontinuous times of the communication signals in the preset time, and judging whether the discontinuous times are more than the preset discontinuous times;

and S210, if the voltage is larger than the preset voltage, judging that the battery to be charged is in a fault state, generating a starting signal, and sending the starting signal to a control terminal of the battery power exchange cabinet.

The method includes the steps that a battery change cabinet control terminal is used for obtaining a communication signal fed back by a battery to be charged during charging through a communication rod, the battery change cabinet control terminal can be an intelligent terminal such as a computer and a touch screen, and the communication signal can be a communication signal fed back by an air pressure sensor in the battery to be charged, a communication signal fed back by a heat-sensitive sensor in the battery to be charged, a communication signal fed back by a current sensor in the battery to be charged and the like; in the communication process, if the current sensor has a fault, one mode is that a pressure parameter communication signal in the battery can be received intermittently and a signal of a certain number of times can be received in a preset time, which indicates that the communication signal can be communicated but has potential safety hazards and small faults; further judging through the mode, the fault point in the battery to be charged can be effectively judged, more fault positions can be detected when the battery is replaced by the battery replacing cabinet, and therefore the whole device is controlled to recover batteries with more fault position point types through the battery replacing cabinet control terminal.

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

acquiring image information of a battery to be charged in a charging frame through a camera, and extracting a charging voltage range value from the image information;

acquiring a real-time charging voltage value within a preset time of the current communication rod;

judging whether the real-time charging voltage value is within the charging voltage range value;

if not, the communication rod is disconnected from the battery to be charged, and the replacement mechanism is started.

In general, when a battery is overcharged, there is a protection device for overcharge in the battery. Taking a mobile phone battery as an example, the principle of the protection device is that a voltage detection protection circuit IC is installed in the battery, and when the internal voltage of the battery is detected to exceed 4.25V, the protection circuit starts a protection system to stop the battery from continuing charging. However, in practical applications, the protected IC may be disabled due to various reasons such as design, management, and process, and at this time, the battery may continue to be charged, and when the charging voltage exceeds 4.5V, if the lithium intercalation capability of the negative electrode is poor, lithium ions may be deposited on the surface of the negative electrode. The deposited lithium crystals form dendrites that penetrate the separator and form dendrite shorts. At the moment, the battery core can be rapidly discharged, a large amount of heat is emitted, the electrolyte can also generate irreversible exothermic chemical reaction under the action of high temperature, and the series of reactions can cause the temperature inside the lithium battery to rise and the internal pressure to rise, so that fire explosion occurs. The image information is an image of a signboard of a battery to be charged, so that a charging voltage value can be obtained from the image, when the voltage value within the preset time exceeds the charging voltage range value, the internal protection circuit IC is in fault, and the charging is stopped at this time, so that the phenomenon that a diaphragm is gradually melted under the double conditions of temperature rise due to overcharging and incapability of dissipating heat, and once the diaphragm is melted, the internal part of the battery is in short circuit can be avoided; at the moment, the battery core can be rapidly discharged, the temperature is rapidly increased, the material of the battery is ignited, finally, fire explosion occurs, the rechargeable battery is timely powered off and the replacement mechanism is started to replace a new battery by utilizing the detection of the fault point, and thus, more accidents can be avoided.
