The invention provides an intelligent battery power-exchanging cabinet system in a first aspect, which comprises a cabinet body 101, wherein a plurality of bin bodies 102 are arranged on the cabinet body 101, a charging module is arranged on each bin body 102, each charging module comprises an over-temperature circuit-breaking protector, a charging plug 104 and a displacement assembly for driving the charging plug 104 to move, one end of each over-temperature circuit-breaking protector is connected with the input end of commercial power through a first lead, the other end of each over-temperature circuit-breaking protector is connected with the charging plug 104 through a second lead, and when the temperature in each bin body 102 is lower than a first preset temperature, the over-temperature circuit-breaking protectors are conducted, and batteries are normally charged; when the temperature in the cabin 102 is higher than a first preset temperature, the over-temperature circuit breaker is turned off to stop charging the battery.

As shown in fig. 1-4, the over-temperature circuit breaker protector includes a mounting base 105, a base 106 is disposed on the top of the mounting base 105, two fixing plates 107 are disposed on one side of the base 106, a temperature change bar 108 is disposed between the two fixing plates 107, a push rod 109 is fixedly connected to the middle of the temperature change bar 108, a conductive block 201 is fixedly connected to the other end of the push rod 109, a guide cavity 202 is disposed on the other side of the base 106, a jacking mechanism is disposed in the guide cavity 202, the jacking mechanism includes a jacking block 203 and a spring 204, one end of the spring 204 is fixedly connected to the inner wall of the guide cavity 202, the other end of the spring is fixedly connected to the jacking block 203, a signal trigger button 205 is further disposed on the inner wall of the guide cavity 202, and a first sensor is disposed on the charging plug 104.

The base 106 is provided with a second groove 206 along the length direction, a first wiring block 207 and a second wiring block 208 are arranged in the second groove 206, the first wiring block 207 is not connected with the second wiring block 208, the first wiring block 207 is connected with the first lead, and the second wiring block 208 is connected with the second lead.

It should be noted that, the over-temperature circuit breaker protector is installed in the bin body 102 through the mounting seat 105, and the specific installation position thereof is not limited herein, for example, the over-temperature circuit breaker protector is installed on the top or the side of the bin body 102, as long as the over-temperature circuit breaker protector is installed in the bin body 102, so as to allow the over-temperature circuit breaker protector to react more accurately, and then control the on-off of the charging circuit more accurately and quickly according to the internal temperature of the bin body 102.

The control principle and process of the over-temperature circuit breaker protector are as follows: the temperature change strip 108 can make different reactions according to the ambient temperature, and when the ambient temperature is higher than the specific temperature, the temperature change strip 108 can be deformed and bent, and after the temperature returns to the normal temperature, the temperature change strip 108 can be restored to the original state. If the temperature in the battery replacement cabinet is continuously increased due to various reasons, after the temperature reaches the deformation temperature of the temperature changing sheet, the temperature changing strip 108 deforms and bends, the temperature changing strip 108 pushes the ejector rod 109 forwards, so that the ejector rod 109 pushes the conductive block 201, the conductive block 201 slides along the first groove 209 and slides into the guide cavity 202 (the spring 204 is in a compressed state), and further the first wiring block 207 and the second wiring block 208 are not conducted any more, so that the flow of the charging circuit is cut off, and the battery is not charged any more; if the temperature in the storehouse body 102 drops to normal scope, temperature change strip 108 reconversion, the spring 204 that compressed this moment resets under the effect of resilience force, and then outwards promotes conducting block 201 for conducting block 201 resets, and then makes first lug 207 and second lug 208 switch on, makes the battery resume normal charging. Thus, when the battery is charged, if the temperature of the bin body 102 is too high, the over-temperature circuit breaker protector can quickly cut off the current of the charging circuit to perform over-temperature protection, so that the situation of battery explosion caused by too high temperature is avoided, and the charging safety of the battery is guaranteed to a great extent. The device adopts the temperature-changing strip as a main control reaction part, the temperature-changing strip is made of metal memory mechanical materials, the traditional control reaction part generally adopts electric parts such as a temperature sensor, and the like, although the reaction degree of the electric parts such as the temperature sensor is sensitive, if the temperature sensor is always in a high-temperature environment, the temperature sensor can be burnt out, so that the temperature sensor fails to work, and then the control function is lost, and further serious accidents can be caused, so the reliability is not high. The temperature changing sheet is made of metal material, and due to the characteristics of the temperature changing sheet, the temperature changing sheet cannot be damaged due to a high-temperature environment, and the reliability is extremely high.

It should be noted that a signal trigger button 205 is arranged in the guide cavity 202, the signal trigger button 205 is in signal connection with an alarm system on the battery replacement cabinet, when the conductive block 201 slides into the guide cavity 202, the signal trigger button 205 is pressed down, an alarm lamp on the alarm system is turned on, the temperature in the battery compartment is too high, and the battery has certain risks, so that a user or a pedestrian is prompted not to approach the battery compartment, and the user or the pedestrian is reminded of the safety of the person.

It should be noted that the first sensor may be a film pressure sensor, and the first sensor is disposed on the charging plug 104. When charging many times, charging plug 104 need continuous grafting, belongs to wearing and tearing piece, after wearing and tearing to a certain degree, when charging plug 104 and battery grafting charge, just can appear contact failure's phenomenon, and then lead to the fact the influence to battery charging, the serious condition that can also appear to battery discontinuous charging, and then burns out the inside components and parts of battery. The conventional method for solving the problem is that the charging plug 104 is replaced after the use times of the charging plug reach the preset use times, but the method has certain defects, the preset use times are values obtained through experimental evaluation and are only estimated values, in the actual plug-in charging process, due to the influence of various factors, the charging plug 104 may have the situation that the charging plug is worn too much in advance and needs to be scrapped, and if the charging plug is replaced after the preset use times are reached, the situation that the battery is burnt due to poor contact still may occur; or after the preset number of times of use is reached, the abrasion degree of the charging plug 104 is still in the allowable range and can still be used continuously, and if the charging plug 104 is replaced at this time, resources are definitely wasted. In order to solve the problems, in the invention, before charging, the pressure of the charging plug 104 in the plug-in connection with the battery is detected through the first sensor, when the pressure is smaller than a preset pressure value, the control system can give a warning to prompt a user to put the battery in other cabin bodies 102 for charging, and the cabin body 102 is marked as an abnormal cabin body 102, a maintenance report is generated, and the maintenance report is sent to a remote maintenance person to prompt the maintenance person to replace the charging plug 104.

Secondly, in the lug 302 embedding spout, play the supporting role for outside conducting block 201 can not fall out second recess 206, in order to satisfy multiple installation needs of excess temperature circuit breaker, for example excess temperature circuit breaker and make the overhead wall of installing at the storehouse body 102 of hanging upside down, conducting block 201 also can not fall, and application range is wider. In addition, the laser receivers on the sliding grooves are numbered in sequence, the position of the conductive block 201 can be accurately and quickly detected through the laser transmitter and the laser receiver for fault detection, for example, when the over-temperature circuit breaker needs to be restored to a conducting state from a disconnecting state, if the spring 204 loses resilience due to faults, the over-temperature circuit breaker cannot be conducted at the moment, the laser transmitter can be controlled to transmit laser, then the laser receiver on which serial number receives laser information is judged, the position of the conductive block 201 is further quickly judged, if the conductive block 201 is still at the position of the disconnecting state of the over-temperature circuit breaker, the spring 204 loses resilience, at the moment, the control system can generate a fault report, the fault information is sent to a user end, maintenance personnel are reminded to replace the spring 204, and therefore, after faults occur, and maintenance personnel are not needed to troubleshoot the faults one by one, so that the labor time is saved, and the labor efficiency is improved.

Meanwhile, in the process of charging the battery, if the battery changing cabinet is influenced by external forces such as collision, the battery in the bin body 102 is difficult to avoid abnormal conditions such as vibration and sliding, the clamping mechanism can well protect the battery at the moment, the situation that the battery falls off due to the vibration and sliding of the battery and the battery is damaged due to mutual collision between the battery and the inner wall of the bin body 102 can be avoided, the safety of the battery is guaranteed, and the reliability of the device is improved.

The constant-current charging mode is simple to operate, the battery capacity can be repaired and the active material can be activated by small current, but the battery is damaged by constant-current charging in the last charging stage, and the irreversible damage to the battery capacity is easily caused. In order to solve the defect, a constant voltage charging mode, namely a constant voltage charging mode, appears on the market, and mainly means that a constant voltage value is applied to two ends of a battery in the whole charging process, the end voltage is kept constant, the current is gradually reduced and finally reduced to a set current value, and the set current value marks the junction speed of the charging process, so that the phenomenon that the current is too large in the last charging stage of the battery can be avoided, the small charging current can balance the ion concentration in the battery, the damage to an electrode material is relieved, and the purpose of prolonging the service life of the battery is achieved.

In the invention, the defects of constant current charging and constant voltage charging, namely overhigh charging multiplying power at the final stage of the constant current charging and overhigh current multiplying power at the initial stage of the constant voltage charging, are combined, and the constant current and constant voltage charging mode is provided, namely the charging process of firstly carrying out the constant current charging and then carrying out the constant voltage charging on the battery during charging. The specific implementation process is as follows: before charging the battery, measuring a current value and a voltage value of the battery before being charged by a circuit detector, and further calculating the current required by the battery during constant current charging and the required charging time (first charging time) according to the current value and the voltage value of the battery before being charged; calculating the voltage required during constant voltage charging and the required charging time (second charging time); and then, constant-current charging is carried out on the battery by adopting the set fixed current, the change condition of the voltage is monitored in real time, when the voltage reaches a preset value, constant-voltage charging is carried out, and the charging is finished until the current is reduced to the preset value. The method can effectively avoid the damage of the battery caused by the overlarge current multiplying power of the battery in the initial stage or the final stage, and the control process is simple.

The method specifically comprises the following steps of collecting a voltage value in a first charging mode and a current value in a second charging mode in real time, and generating a detection report:

if so, marking the first sub-charging time period as an abnormal point;

if so, marking the second sub-charging time period as an abnormal point;

It should be noted that, in the stage of constant current charging, the voltage gradually increases until the preset voltage value is reached; in the constant voltage charging stage, the current is gradually reduced until a preset current value is reached. Calculating theoretical charging time (first charging time) of the battery in a constant current charging mode and theoretical charging time (second charging time) of the battery in a constant voltage charging mode by a data processor on a control system according to a current value and a voltage value of the battery before being charged; then dividing the first charging time into a plurality of first sub-charging time periods, calculating theoretical voltage change rates (namely the preset voltage change rates) corresponding to the plurality of first sub-charging time periods, and storing the theoretical voltage change rates in a storage; the second charging time is divided into a plurality of second sub-charging time periods, and theoretical current change rates (i.e. the preset current change rates) corresponding to the plurality of second sub-charging time periods are calculated and stored in the storage. When the battery is charged, acquiring the first voltage change rate of each first sub-charging time period, and comparing the first voltage change rate with the corresponding preset voltage change rate to further judge whether the battery is an abnormal point during charging in the time period; acquiring a first current change rate of each second sub-charging time period, and comparing the first current change rate with a corresponding preset current change rate to further judge whether the battery is an abnormal point during charging in the time period; the processor may then perform data analysis on each abnormal time point to generate a detection report. If no abnormal point or only a few scattered abnormal points appear in the charging process, marking the battery as a normal battery; if a plurality of scattered abnormal points appear in the charging process, generating a primary warning to inform a user to overhaul the battery; if a plurality of continuous abnormal points occur, a secondary warning is generated, which indicates that the battery can not be used continuously and needs to be scrapped. According to the invention, whether the battery has a fault is further determined by analyzing the voltage and current change condition of the battery during charging so as to remind a user to overhaul or replace, risks can be found in time, and the occurrence rate of safety accidents is greatly reduced.

In addition, the invention can judge whether the battery reaches the scrapping degree by measuring the charging time of the battery so as to remind a user of replacing the battery in time and improve the safety of the battery in use. The specific implementation process is as follows: when the battery is charged, recording the actual charging time of the battery in a first charging mode, and marking the actual charging time as first actual time; recording the actual charging time of the battery in the second charging mode, and marking the actual charging time as second actual time; calculating a difference value between the first charging time and a first actual time to obtain a first time deviation; calculating a difference value between the second charging time and a second actual time to obtain a second time deviation; when the first time deviation is greater than a first preset deviation, or/and the second time deviation is greater than a second preset deviation; indicating that a fault has occurred within the battery. Specifically, when the actual charging time of the battery is far shorter than the theoretical charging time (the sum of the first charging time and the second charging time), it indicates that the active materials in the battery are seriously fallen off, so that the electrolyte has more deposits, and the electrolyte is turbid during charging, so that the storage capacity of the battery is greatly reduced; when the actual charging time of the battery is far longer than the theoretical charging time (the sum of the first charging time and the second charging time), it indicates that faults such as partial aging and short circuit may occur in the internal circuit of the battery, resulting in a long charging time. Therefore, in practical application, if the difference between the actual charging time and the theoretical charging time is not large, the fault of the battery is still within an allowable range and the battery can still be used continuously; however, if the difference between the actual charging time and the theoretical charging time is too large, it is indicated that the battery has reached the scrapping degree, and the scrapping treatment is required, especially for the fault of line aging and short circuit, if the battery is still used, the temperature of the battery will continuously rise in the long-time charging process, the temperature can rise to thousands of degrees, meanwhile, the internal air pressure of the battery will also continuously increase, the pressure can suddenly increase to several or even dozens of atmospheric pressures, and the high-temperature and high-pressure gas rapidly expands to the periphery, thereby causing the explosion phenomenon and causing serious influence on the society.

It should be noted that, if the over-temperature trip protector is triggered during the charging process, the voltage and the current both become zero, and the control system can determine the situation, and does not mark the situation as an abnormal point; at the same time, this power-off time is not logged into the actual charging time.

While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
