The main control module can
In some embodiments, the type of addressing signal is matched to the signal line. For example, the signal line is a pulse width modulated signal line, and the address signal may be a pulse width modulated signal (Pulse width modulation, PWM).
In some embodiments, the slave module may receive the addressing signal sent by the master module. The slave control module may compare the preset signal strength reference value with the strength difference between the signal strengths of the received address signals. The slave module may determine a coded address matching the intensity difference and determine the coded address as the coded address of the home module.

It can be appreciated that the addressing of each slave module can be made independent by the parallel connection of the master module and the slave modules, independent of other slave modules.
Illustratively, each slave module in the battery management system is directly connected to the master module by a signal line such that the master module is able to directly communicate with each slave module. It can be understood that the slave control modules are in one-to-one correspondence with the signal lines, and each signal line is used for directly connecting the slave control module with the master control module so as to realize that the slave control modules are connected with the master control module in parallel. The master control module can determine each slave control module connected with the local end module in parallel, and determines the slave control module to be addressed from each slave control module. The signal line is used for transmitting addressing signals sent by the main control module aiming at the slave control module to be addressed. In some embodiments, the master control module and each slave control module are connected in parallel through a plurality of pulse width modulation signal lines.
In some embodiments, each slave module to be addressed may include at least one of all slave modules connected in parallel with the master module. That is, each slave module to be addressed may be all slave modules, or may be some of all slave modules, for example, the slave module to be addressed may be a slave module in a normal state among all slave modules.

In the addressing processing method, an addressing signal is sent to a slave control module to be addressed, which is connected with a master control module; the method comprises the steps of aiming at different signal strengths of addressing signals sent by different slave control modules to be addressed, wherein the addressing signals are used for indicating the slave control modules to be addressed to address based on the signal strengths of the addressing signals; the method comprises the steps of acquiring addressing feedback information returned by the slave control modules to be addressed, addressing each slave control module to be addressed by addressing signals with different signal intensities in a targeted manner, and addressing the slave control modules manually without manual operation, so that unpacking operation steps and damage to batteries caused by unpacking are avoided, and addressing cost is reduced.
In some embodiments, before sending the addressing signal to the slave module to be addressed, which is connected to the master module, the method further includes: acquiring state characterization signals sent by each slave control module connected with the master control module in parallel; and under the condition that the state characterization signal characterizes the state of the slave control module to be normal, determining the slave control module as the slave control module to be addressed.
The state characterization signal is used for characterizing the state of the slave control module.
For example, the slave module may send a state characterization signal to the slave module. The master control module can determine the time characteristic information of the acquired state characterization signals. The master control module can determine the slave control module as the slave control module to be addressed under the condition that the state corresponding to the time characteristic information is normal.
In some embodiments, the time characteristic information may include at least one of a duty cycle or a signal frequency, etc. It can be appreciated that the master control module can determine a preset status threshold. Each state threshold indicates a state. The master control module can determine the state of the slave control module represented by the state representation signal by comparing a preset state threshold value with time characteristic information.
In some embodiments, the time characteristic information is a signal frequency. The master control module can determine the state indicated by the state threshold value consistent with the signal frequency as the state of the slave control module by comparing the signal frequency of the state representation signal with a preset state threshold value.
In some embodiments, the preset status threshold may include at least one of a first preset frequency or a second preset frequency. The first preset frequency is used for indicating that the slave control module is in a normal state. The second preset frequency is used for indicating that the slave control module is in an abnormal state.

In some embodiments, the status characterization signal may characterize whether the communication of the slave module is normal and whether the monitored battery data is normal. It can be appreciated that the master control module may determine that the communication of the slave control module is abnormal in the case that the state characterization signal is not acquired. The main control module can report the communication abnormality to the host computer aiming at the slave control module with the communication abnormality.
In the embodiment, state characterization signals sent by each slave control module connected with the master control module in parallel are obtained; under the condition that the state of the state characterization signal characterization slave control module is normal, the slave control module is determined to be the slave control module to be addressed, and then the slave control module with the normal state is addressed, so that the addressing accuracy can be ensured.
In some embodiments, before determining the slave module as the slave module to be addressed, the method further comprises, in case the state characterization signal characterizes that the state of the slave module is normal: determining a signal frequency of the state characterization signal; and under the condition that the signal frequency is the first preset frequency, determining that the state representation signal represents that the state of the slave control module is normal.
The master control module may determine whether the signal frequency of the state characterization signal is a first preset frequency, and determine that the state of the slave control module sending the state characterization signal is normal when the signal frequency is the first preset frequency. It can be understood that the normal state of the slave control module means that the communication between the slave control module and the master control module is normal and the monitored battery data is normal.
In some embodiments, the slave control module may send a state characterization signal with a signal frequency of a first preset frequency to the master control module in the case that no abnormality exists in the battery data monitored by the slave control module. It will be appreciated that the absence of an anomaly in the battery data means that the battery data monitored by the slave module is in a normal range. The battery data may include at least one of battery voltage or temperature, etc.
In this embodiment, the signal frequency of the state characterization signal is determined; under the condition that the signal frequency is the first preset frequency, the state of the state representation signal representation slave control module is determined to be normal, and then the slave control module in the normal state is addressed, so that the influence of the abnormal slave control module can be avoided, and the addressing accuracy is ensured.
In some embodiments, the method further comprises: under the condition that the signal frequency is a second preset frequency, determining that the state representation signal represents that the battery data monitored by the slave control module is abnormal; and reporting the abnormality to the host computer aiming at the monitored slave control module with the abnormality in the battery data.
The master control module may determine whether the signal frequency is a second preset frequency, and determine that the battery data monitored by the slave control module that sends the state characterization signal is abnormal when the signal frequency is the second preset frequency. The main control module can not address the monitored battery data with the abnormal slave control module and report the abnormal battery data to the upper computer. The upper computer can position the slave control module indicated by the abnormal information after receiving the abnormal information reported by the master control module. It will be appreciated that the priority of handling exceptions for the slave is higher than the priority of addressing for the slave.
In some embodiments, as shown in fig. 3, a schematic structural diagram of a master control module is provided. The main control module internal structure comprises a cluster voltage and current acquisition module, an equalization control module, an alarm module, a calculation module and a communication interface. The calculation module is used for mainly estimating the state of charge parameter of the power battery and the state of health parameter of the power battery. The alarm module is used for processing various anomalies and reporting to the upper computer. The equalization control module adopts passive equalization to eliminate the inconsistency of the battery packs. It can be understood that the main control module can output the addressing signal through the signal output module. The main control module can report the abnormality to the upper computer through the alarm module.
In some embodiments, the master control module may report the abnormality to the host computer through the slave control module with the abnormality of the monitored battery data by the alarm module.
In some embodiments, the state characterization signal may be a pulse width modulated signal. Wherein the state characterization signal is a first pulse width modulation signal and the addressing signal is a second pulse width modulation signal.
In some embodiments, in the case that the monitored battery data has an abnormal slave control module that resumes a normal state, the slave control module may send a state characterization signal of a first preset frequency to the master control module. The main control module can determine that the slave control module is in a normal state based on a state characterization signal of a first preset frequency, and independently address the slave control module based on the current addressing condition.
In some embodiments, the slave modules connected in parallel with the master module include an unaddressed slave module and an addressed slave module. The unaddressed slave may be a newly added slave or a slave that resumes its normal state. Under the condition that the unaddressed slave control modules are in a normal state, the master control module can determine addressing signals with different intensities according to the number of the addressed slave control modules, the number of the unaddressed slave control modules and a preset signal intensity reference value. The main control module sends addressing signals with different intensities to each addressed slave control module respectively. For example, if the number of addressed slave modules is n and the number of unaddressed slave modules is i, the master control module may determine (n+1) P … … (n+i) P addressing signals with different intensities.
In some embodiments, each slave module may send a state characterization signal to the master module again when the monitored battery data is in a normal state. The main control module can carry out addressing processing on each slave control module which is connected in parallel again.
In this embodiment, under the condition that the signal frequency is the second preset frequency, it is determined that the battery data monitored by the state characterization signal characterization slave control module is abnormal; the abnormal slave control module is used for reporting the abnormality to the upper computer aiming at the monitored battery data, so that the related faults and the abnormality of the slave control module can be timely checked, the abnormal slave control module is not addressed, and the addressing accuracy can be ensured.
In some embodiments, the method further comprises: under the condition that the number of the addressing feedback is consistent with the number of the slave control modules which send the state characterization signals representing the normal state, the completion of addressing of each slave control module to be addressed is judged; wherein, the addressing feedback quantity is the quantity of slave control modules which return addressing feedback information.
Illustratively, the main control module may count the received addressing feedback information to obtain the number of addressing feedback. The main control module can compare the addressing feedback quantity with the quantity of the slave control modules to be addressed, and under the condition that the quantity of the addressing feedback quantity is consistent with the quantity of the slave control modules to be addressed, the completion of addressing of each slave control module to be addressed is judged.
In some embodiments, the master control module may determine that there is an abnormality in addressing of each slave control module to be addressed when the two numbers are inconsistent. The main control module can report the abnormality to the upper computer. It can be understood that the master control module can feed back to the upper computer the slave control module which does not receive the addressing feedback information, or the slave control module which codes address errors in the addressing feedback information and other abnormal slave control modules.
In some embodiments, the addressing feedback information includes a coded address of the slave module. The main control module can judge whether the addressing of each slave control module to be addressed is finished or not by matching the fed back coding address with the number of the slave control modules to be addressed. And under the condition that the fed back coded address is matched with the number of the slave modules to be addressed, determining that the addressing is completed.
In some embodiments, the coded address may indicate the amount of addressing feedback. The coded address fed back should be matched to the number of slave modules to be addressed. For example, the number of slave modules to be addressed is n, and each slave module to be addressed may be addressed to 1, 2 … … n. The main control module can determine the addressing feedback quantity of the coding address indication.
In some embodiments, as shown in fig. 4, a schematic structural diagram of a slave module is provided. The internal structure of the slave control module comprises a signal input module, a single voltage and current acquisition module, an alarm module, an equalization module, a feedback module and a communication interface. It can be understood that the slave control module can send addressing feedback information to the master control module through the feedback module, wherein the addressing feedback information comprises the coding address of the slave control module.
In this embodiment, under the condition that the number of the addressing feedback is consistent with the number of the slave control modules sending the state characterization signals representing the normal states, the addressing of each slave control module to be addressed is judged to be completed, the addressing completion condition can be judged in time, the addressing abnormal condition can be processed in time, and the addressing accuracy is ensured.
In some embodiments, sending an addressing signal to a slave module to be addressed, connected to a master module, includes: determining the signal intensity of each addressing signal according to a preset signal intensity reference value and the number of slave control modules to be addressed, and obtaining addressing signals with different intensities; and respectively sending addressing signals with different intensities to each slave control module to be addressed.
For example, the main control module may determine a signal strength of each of the address signals and output the address signals of different strengths. Wherein the number of addressing signals with different intensities is consistent with the number of slave modules to be addressed. The signal intensities of the plurality of address signals are represented as an arithmetic progression, the tolerance is a unit intensity variation value, and the minimum signal intensity is a signal intensity reference value.
In some embodiments, the signal strength reference value may be a unit strength variation value. It can be understood that the difference between the adjacent intensity-sized addressing signals is a signal intensity reference value. For example, if the signal strength reference value is P and the number of slave modules to be addressed is n, the signal strengths of the plurality of addressing signals are P and 2*P … … n×p respectively.
In some embodiments, the signal strength reference value may be determined from a fullness value of the signal strength and a maximum number of slave modules. For example, the signal strength reference value may be a ratio of a fullness value to a maximum number. For example, the fullness value is Pmax, the maximum number is m, and the signal strength reference value is Pmax/m.
In this embodiment, according to a preset signal strength reference value and the number of slave control modules to be addressed, determining the signal strength of each addressing signal to obtain addressing signals with different strengths; and the slave control modules to be addressed respectively send addressing signals with different intensities, so that the slave control modules can address based on the intensity of the addressing signals, the manual addressing is not needed, and the cost is reduced.
In some embodiments, determining the signal strength of each addressing signal according to the preset signal strength reference value and the number of slave modules to be addressed, and obtaining the addressing signals with different strengths includes: determining an intensity change coefficient matched with the number of slave modules to be addressed; and increasing the signal intensity according to the intensity change coefficient and a preset signal intensity reference value, determining the signal intensity of each addressing signal, and obtaining the addressing signals with different intensities.
For example, the master control module may determine a plurality of intensity variation coefficients of different sizes. The number of intensity variation coefficients corresponds to the number of slave modules to be addressed. For example, the number of slave modules is n, so that there are n intensity change coefficients, and the magnitudes of the n intensity change coefficients are sequentially increased. The main control module can determine the product of the intensity change coefficient and a preset signal intensity reference value to obtain the signal intensity of each addressing signal so as to output addressing signals with different intensities, so that the signal intensities of the plurality of the outputted addressing signals are sequentially increased.
In some embodiments, the magnitudes of the plurality of intensity variation coefficients may be represented as an arithmetic progression. The tolerance for the plurality of intensity variation coefficients may be in units of 1. For example, if the number of slave modules to be addressed is n, the intensity change coefficients are 1, 2 … … n.
In some embodiments, the slave control module may parse the received addressing signal to identify a signal strength of the addressing signal, and determine a ratio between the signal strength of the received addressing signal and a signal strength reference value to obtain a strength change coefficient. Further, the slave module may determine the intensity change coefficient as the encoded address of the home module. For example, the intensity conversion coefficient is 1 … … n, the signal intensity reference value is P, the signal intensities of the plurality of addressing signals are 1*P … … n×p, the code address of the slave module receiving the addressing signal of 1*P intensity is 1, and the code address of the slave module receiving the addressing signal of n×p intensity is n.
In some embodiments, the master module may determine an intensity variation coefficient that matches the number of addressed slave modules and the number of unaddressed slave modules.
In some embodiments, the intensity change coefficient corresponding to the slave module to be addressed is the first intensity change coefficient. In the case that the unaddressed slave modules are in a normal state, the master module may determine a number of second intensity variation coefficients of different magnitudes that are consistent with the number of unaddressed slave modules. Wherein the plurality of first intensity variation coefficients and the plurality of second intensity variation coefficients are represented as an arithmetic progression. The minimum value of the second intensity variation coefficient is larger than the maximum value of the first intensity variation coefficient.
In the embodiment, determining an intensity change coefficient matched with the number of slave modules to be addressed; and the signal intensity increment is carried out according to the intensity change coefficient and a preset signal intensity reference value, the signal intensity of each addressing signal is determined, the addressing signals with different intensities are obtained, the addressing processing is carried out on the slave control module in a targeted manner based on the addressing signals with different intensities, manual addressing is not needed, and the cost is reduced.
In some embodiments, a simplified flow diagram of an addressing process is provided, as shown in fig. 5. The slave control module sends a state characterization signal to the master control module. The main control module can judge whether the signal frequency of the state representation signal is a first preset frequency or not, and if not, the main control module reports abnormality; if yes, the slave module sending the state characterization signal is the slave module to be addressed. The upper computer can issue an address allocation instruction to the main control module, and instruct the main control module to send an addressing signal to the slave control module to be addressed. It can be appreciated that the master control module may transmit addressing signals of different intensities in order of low to high signal intensities. And if the number of the slave control modules to be addressed is n, the slave control modules are sequentially addressed to 1 and 2 … n according to the signal intensity of the received addressing signals, and addressing feedback information is returned to the main control module. The main control module can judge whether the addressing feedback quantity is the quantity of the slave control modules to be addressed, if not, the main control module performs abnormal reporting, and if so, the addressing is determined to be completed.
