As the requirements of electric vehicles on the driving range are higher, the energy density of the battery is increased by times. The formation of the lithium ion battery can be divided into two stages of constant current charging and constant voltage charging, namely, small current trickle charging is adopted to enable the battery terminal voltage to reach the discharge termination voltage, then constant current charging is carried out until the battery terminal voltage reaches the constant voltage charging voltage, and then constant voltage charging is carried out until the battery terminal voltage is full.
Fig. 1 illustrates a simple example of a formation apparatus, the formation apparatus illustrated in fig. 1 having a plurality of stations 101, each station 101 including a plurality of channels 102, and a battery disposed within the channels 102, each channel 102 for forming a battery. All problems of the former stage process are exploded in the process, so that the battery has a very high failure risk, and how to rapidly process the failed battery becomes the important point of the formation process.
The embodiment of the application provides a battery formation system 200, referring to fig. 2, the battery formation system 200 includes an acquisition module 201, a judgment module 202 and a processing module 203.
The collection module 201 is used for collecting operation data of the formation equipment. The judging module 202 is used for determining the early warning level of the formation equipment according to the operation data. The processing module 203 is configured to perform corresponding processing operations on the formation device according to the early warning level.
The preset early warning level comprises local early warning and complete machine early warning, and the local early warning is used for carrying out local (such as a channel or a warehouse site) abnormal early warning on formation equipment, for example, the battery in the channel can be abnormal in voltage, current, temperature and other aspects in the charging and discharging process, so that the battery is invalid or the channel fires, and for example, any channel in the warehouse site or the battery in the channel is abnormal, so that the battery in the whole warehouse site is invalid or the warehouse site fires. The whole machine level early warning is used for carrying out early warning on the whole abnormality of the formation equipment, for example, any stock position abnormality in the formation equipment can possibly cause the failure of a battery in the whole formation equipment or the ignition of the formation equipment.
As described above, the embodiment of the application performs step-by-step early warning processing on the formation equipment from a part to the whole machine based on the structural design of the formation equipment, so that accurate early warning on the formation equipment can be realized, the early warning precision of a battery formation system is improved, the production efficiency is not affected by false alarm, and the early warning object is positioned to the part of the formation equipment, so that the formation equipment can be correspondingly processed at the initial stage of local abnormality of the formation equipment, and abnormal diffusion and damage to a normal battery due to false alarm operation are avoided.
In order to realize local accurate early warning of the formation equipment, the local early warning can comprise channel early warning, wherein the judging module is used for judging whether the battery voltage, the battery current or the battery temperature acquired by the acquisition module is abnormal, if so, determining that a channel corresponding to abnormal data is an abnormal channel, and determining that the early warning level of the formation equipment is channel early warning; and the processing module is used for stopping the formation equipment from charging and/or discharging the battery in the abnormal channel when the early warning level of the formation equipment is in the channel level early warning.
Specifically, the judging module is used for judging:
a1, judging whether the battery voltage acquired by the acquisition module is larger than or smaller than a voltage threshold value under a corresponding primary working condition, wherein the primary working condition for battery formation comprises the following steps: idle condition, constant current charging condition and rest condition. The resting condition refers to that the battery is stood for a period of time, and the battery is usually placed regularly during charging or discharging according to experimental requirements. Idle conditions refer to no operation of the battery for a long period of time.
For example, whether the voltage of the battery in the constant current charging working condition is greater than a voltage safety threshold can be judged, if the voltage of the battery in the constant current charging working condition is greater than the voltage safety threshold, the abnormality of the channel in which the battery is positioned is indicated, and the channel level abnormality protection is required to be started; or judging whether the voltage of the battery in the constant current charging working condition is reduced to an abnormal point or not, if the voltage of the battery in the constant current charging working condition is reduced to the abnormal point, indicating that the channel where the battery is located is abnormal, and starting channel level abnormal protection; or judging whether the voltage drop value of the battery in the constant current charging working condition suddenly drops and the drop value is larger, if the voltage drop value of the battery in the constant current charging working condition suddenly drops and the drop value is larger, indicating that the channel where the battery is located is abnormal, and starting channel level abnormal protection; or can judge whether the voltage of the battery in the resting working condition suddenly drops and the drop amplitude is larger, if the voltage of the battery in the resting working condition suddenly drops and the drop amplitude is larger, the channel where the battery is located is abnormal, and the channel level abnormality protection needs to be started.
a2, judging that the voltage fluctuation of the battery collected by the collection module is larger than the voltage fluctuation range under the corresponding first-level working condition, for example, judging whether the voltage of the battery in the idle working condition has larger voltage fluctuation or not, if the voltage of the battery in the idle working condition has larger voltage fluctuation, indicating that the channel where the battery is located is abnormal, and starting channel-level abnormal protection; the method can also judge whether the voltage of the battery in the idle working condition continuously fluctuates, and if the voltage of the battery in the idle working condition continuously fluctuates, the channel in which the battery is located is abnormal; or can judge whether the voltage of the battery under the shelving working condition has larger voltage fluctuation, if the voltage of the battery under the shelving working condition has larger voltage fluctuation, the channel in which the battery is positioned is abnormal, and the channel level abnormal protection needs to be started.
A3, judging whether the battery current acquired by the acquisition module is larger than a current threshold value under a corresponding primary working condition, for example, judging whether the current of the battery in a constant current charging working condition is larger than a current safety threshold value, if the current of the battery in the constant current charging working condition is larger than the current safety threshold value, indicating that the channel where the battery is located is abnormal, and starting channel level abnormal protection is needed.
a4, judging whether the temperature of the battery collected by the collection module is higher than the primary protection temperature of the battery;
if any one of the conditions a1 to a4 is satisfied, the corresponding channel can be determined to be an abnormal channel, a channel-level early warning signal is output, and the formation equipment stops charging and/or discharging the battery in the abnormal channel. By stopping formation of the battery in the designated channel, abnormal channels and continuous deterioration of the battery thereof can be avoided, and it is to be noted that a plurality of sub-conditions corresponding to channel-level early warning are not limited to a1-a4, and those skilled in the art can add or subtract according to actual situations.
To enable accurate determination of channel level pre-warning, the acquisition module 201 may include a plurality of channel acquisition units, each comprising one or more of the following sensors: a current sensor, a voltage sensor, a battery temperature sensor, and a channel temperature sensor; the current sensor is used for collecting current data of the battery in the channel; the voltage sensor is used for collecting voltage data of the battery in the channel; the battery temperature sensor is used for collecting temperature data of the battery in the channel; the channel temperature sensor is used for collecting temperature data of the channel. That is, embodiments of the present application are capable of individually sampling the current and voltage of a battery in a single channel. For example, the sampling precision of the current and the voltage is 0.1% after 1s sampling, and each battery can be sampled by a PT100 temperature sensor and is uploaded to the processing module 203 after analog-digital conversion.
After the channel-level early warning of the formation equipment is determined, the data of the designated channel needs to be continuously monitored in the aspects of voltage, current, temperature and the like so as to know whether the abnormal channel condition is recovered to be normal or continuously deteriorated.
To achieve local accurate pre-warning of the formation equipment, local level pre-warning may also include library level pre-warning; the judging module is also used for judging:
b1, judging whether the battery voltage of the abnormal channel is larger than a voltage threshold value under the corresponding second-level working condition; the secondary working conditions for battery formation comprise: discharging working condition, under which the battery is in working state;
for example, whether the voltage (full-time voltage) of the battery in the abnormal channel in the whole charging or discharging process is larger than a limit voltage threshold value can be judged, if the full-time voltage of the battery in the abnormal channel is larger than the limit voltage threshold value, the situation that the battery voltage in the abnormal channel is too high and the abnormal channel is continuously deteriorated is indicated, and the library level abnormal protection needs to be started for the library level where the abnormal channel is located; or judging whether the voltage suddenly rises when the battery works in the abnormal channel, if the voltage suddenly rises and the lifting amplitude is larger when the battery works, indicating that the battery works abnormally, the situation of the abnormal channel continuously worsens, and starting the library level abnormal protection for the library where the abnormal channel is located.
b2, if the battery temperature of the abnormal channel is higher than the battery secondary protection temperature, the battery secondary protection temperature is higher than the battery primary protection temperature, if the battery temperature of the abnormal channel is higher than the battery secondary protection temperature, the battery temperature is too high, the situation of the abnormal channel is continuously deteriorated, and the library level abnormal protection needs to be started for the library where the abnormal channel is located.
