[0023] A Battery Management System (BMS) is used for hierarchical and unified management of individual cells, battery packs, and battery stacks. It calculates and analyzes various parameters and operating states of batteries (cells, packs, stacks) based on the characteristics of each level. This enables effective management in areas such as balancing, alarms, and protection, ensuring equal output from each battery pack, intelligent management and maintenance of each battery unit, prevention of overcharging and over-discharging, extension of battery life, and monitoring of battery status.

However, current EMU technologies lack universal detection capabilities for various signals, and their signal detection ports cannot be expanded, causing inconvenience during environmental analog quantity testing. Therefore, finding a universal detection method for various types of environmental analog quantities has become a major challenge in the industry.

[0025] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an environmental analog quantity detection device and method, electronic device, and storage medium, which can perform universal detection of various types of environmental analog quantities.

[0026] Reference Figure 1A An environmental analog quantity detection device 100 according to a first aspect embodiment of the present invention includes a power supply module 110, a communication module 120, a central processing module 130, a selection circuit 140, and a first detection module 150 and a second detection module 160 arranged in parallel.

[0027] Reference Figure 1B In some embodiments, the environmental simulation quantity detection device 100 may include, in addition to the first detection module 150 and the second detection module 160 arranged in parallel, a third detection module, a fourth detection module, ..., an Nth detection module arranged in parallel with the first detection module 150 and the second detection module 160.

[0028] The power supply module 110 supplies power to the communication module 120, the central processing module 130, the selection circuit 140, the first detection module 150, and the second detection module 160. In some embodiments, the communication module 120, the central processing module 130, the selection circuit 140, or the first detection module 150 and the second detection module 160 need to operate normally when powered on, and therefore require power supply from the power supply module 110.

[0029] Reference Figure 1C In some embodiments, the power supply module 110 of the environmental analog quantity detection device 100 includes a switching power supply 111, a first isolation power supply 112, and a second isolation power supply 113. The switching power supply 111 is connected to the first isolation power supply 112 and the second isolation power supply 113. The first isolation power supply 112 supplies power to the central processing module 130, the selection circuit 140, the first detection module 150, and the second detection module 160, while the second isolation power supply 113 supplies power to the communication module 120. It should be noted that because the central processing module 130, the selection circuit 140, the first detection module 150, and the second detection module 160 are interconnected and closely linked, they are all powered by the first isolation power supply 112. The communication module 120 is more independent than the other components within the environmental analog quantity detection device 100, therefore it is powered by the second isolation power supply 113. In this way, when the central processing module 130, selection circuit 140, first detection module 150 and second detection module 160 experience line faults and power outages, the communication module 120 can still maintain normal communication with the outside world, which improves safety performance and facilitates the execution of operation and maintenance tasks.

[0030] The communication module 120 is used to acquire analog signal detection commands and send them to the central processing module 130. It should be noted that the communication module 120 can be used not only to acquire analog signal detection commands but also for other types of communication interactions with external devices, such as data uploading and fault alarms. In some exemplary embodiments, after the environmental analog signal detection device 100 obtains the analog signal detection value, it can upload it using the communication module 120. The communication module 120 may include hardware circuitry based on RS422 communication, RS485 communication, or RS232 communication. It should be understood that the optional implementations of the communication module 120 are diverse and may include, but are not limited to, the specific embodiments described above.

[0031] The central processing module 130 parses and processes analog signal detection commands, determines the type of analog signal to be detected and the detection configuration parameters, and sends the analog signal type to the selection circuit 140. After the central processing module 130 is connected to the first detection module 150, it controls the first detection module 150 to perform analog signal detection of the first type according to the detection configuration parameters, and obtains the first analog signal detection value. After the central processing module 130 is connected to the second detection module 160, it controls the second detection module 160 to perform analog signal detection of the second type according to the detection configuration parameters, and obtains the second analog signal detection value. In some more specific embodiments, the central processing module 130 may include a microcontroller.

[0032] The selection circuit 140 is used to connect the central processing module 130 and the first detection module 150 when the analog signal type is type 1, or to connect the central processing module 130 and the second detection module 160 when the analog signal type is type 2. In some more specific embodiments, the selection circuit 140 may include an 8-to-1 analog switch chip connected to the positive terminal of the operational amplifier in the central processing module 130, while the negative terminal of the operational amplifier has two voltage divider resistors reserved. The analog switch chip may have three configurable selection channels, H1, H2, and H3, which can be selected by software configuration. For example, H1H2H3=001 corresponds to channel 1, H1H2H3=010 corresponds to channel 2, H1H2H3=011 corresponds to channel 3, ..., H1H2H3=111 corresponds to channel 8.

[0033] It should be noted that different types of analog quantities require different detection modules for acquisition. For example, the first detection module 150 can be a current detection module, the second detection module 160 can be a voltage detection module, and some embodiments may also include a third detection module for temperature detection. Therefore, with the cooperation of the central processing module 130 and the selection circuit 140, the central processing module 130 can parse the type of analog quantity to be detected and the corresponding detection configuration parameters. The selection circuit 140 establishes a connection between the central processing module 130 and the detection module according to the analog quantity type, and then the central processing module 130 controls the detection module to perform analog quantity detection based on the corresponding detection configuration parameters. In this way, universal detection of various types of environmental analog quantities can be achieved.

[0034] Reference Figure 2 According to some embodiments of the present invention, the first detection module 150 includes a first power input terminal 151, a first ground terminal 152, a first selection terminal 155 and a current signal detection terminal 157; A first resistor 153 is provided between the first power input terminal 151 and the first ground terminal 152.

Specifically, the voltage divider circuit composed of the first resistor 153 and the third resistor 158 in the first detection module 150 can generate a first analog detection value based on the current value input to the current signal detection terminal 157. In some more specific embodiments, a first capacitor 1511 may be provided between the first selection terminal 155 and the first ground terminal 152. The first capacitor 1511 and the second resistor 156 form an RC filter circuit, which can better protect the selection circuit 140 connected to the first selection terminal 155. It should be understood that the first capacitor 1511 is used to filter the signal input to the selection circuit 140, and may be omitted in some embodiments.

[0035] Reference Figure 3 According to some embodiments of the present invention, the second detection module 160 further includes a second power input terminal 161, a second ground terminal 162, a second selection terminal 165 and a voltage signal detection terminal 167; A fourth resistor 163 is provided between the second power input terminal 161 and the second ground terminal 162.

A fourth node 169 is provided between the voltage signal detection terminal 167 and the sixth resistor 168. A second bidirectional transient voltage suppression diode 1610 is provided between the fourth node 169 and the second ground terminal 162. It should be noted that when measuring the current signal, the fourth resistor 163 and the sixth resistor 168 form a voltage divider circuit, wherein the second bidirectional transient voltage suppression diode 1610 is a protective device, and the fifth resistor 166 can be used to protect the selection circuit 140 connected to the second selection terminal 165. Specifically, the voltage divider circuit composed of the fourth resistor 163 and the sixth resistor 168 in the second detection module 160 can generate a second analog detection value based on the voltage value input to the voltage signal detection terminal 167. In some more specific embodiments, a second capacitor 1611 may be provided between the second selection terminal 165 and the second ground terminal 162. The second capacitor 1611 and the fifth resistor 166 form an RC filter circuit, which can better protect the selection circuit 140 connected to the second selection terminal 165. It should be understood that the second capacitor 1611 is used to filter the signal input to the selection circuit 140, and may be omitted in some embodiments.

[0036] Reference Figure 4 According to some embodiments of the present invention, the environmental analog quantity detection device 100 further includes a third detection module arranged in parallel with the first detection module 150 and the second detection module 160; wherein the third detection module further includes a third power input terminal 171, a third ground terminal 172, a third selection terminal 175 and a temperature signal detection terminal 177; A seventh resistor 173 is provided between the third power input terminal 171 and the third ground terminal 172.

It should be noted that when measuring the temperature signal, the seventh resistor 173 and the ninth resistor 178 form a voltage divider circuit. The temperature signal detection terminal 177 can be connected to a thermistor, whose resistance changes accordingly with the change of ambient temperature. Specifically, through the voltage divider circuit composed of the seventh resistor 173 and the ninth resistor 178 in the third detection module, combined with the resistance change of the thermistor, a third analog detection value can be generated according to the change of ambient temperature. The third bidirectional transient voltage suppressor diode 1710 is a protective device, and the eighth resistor 176 can be used to protect the selection circuit 140 connected to the third selection terminal 175.

It should be understood that the third capacitor 1711 is used to filter the signal input to the selection circuit 140, and can be omitted in some embodiments.

[0037] Reference Figure 5 According to a second aspect of the present invention, step S500 of an environmental analog quantity detection method is applied to an environmental analog quantity detection device 100. The environmental analog quantity detection method may include, but is not limited to: Step S501: Obtain the analog quantity detection command through the communication module and send the analog quantity detection command to the central processing module; Step S502: The central processing module parses and processes the analog quantity detection command to determine the type of analog quantity to be detected and the detection configuration parameters, and sends the analog quantity type to the selection circuit. Step S503: When the analog quantity type is the first type, the central processing module and the first detection module are connected via the selection circuit, and the central processing module controls the first detection module to perform analog quantity detection of the first type according to the detection configuration parameters to obtain the first analog quantity detection value. In step S504, when the analog quantity type is the second type, the central processing module and the second detection module are connected via the selection circuit, and the central processing module controls the second detection module to perform the second type of analog quantity detection according to the detection configuration parameters to obtain the second analog quantity detection value.

[0038] The above-described method for detecting environmental analog quantities in an environmental analog quantity detection device allows for the connection between a central processing module and a corresponding detection module via a selection circuit, based on the type of analog quantity to be detected and the detection configuration parameters. The central processing module then controls the corresponding detection module to collect environmental analog quantities according to the detection configuration parameters, thereby enabling general detection of various types of environmental analog quantities.

[0039] In step S501 of some embodiments, an analog signal detection command is obtained through the communication module and then sent to the central processing module. It should be noted that the communication module is used to obtain the analog signal detection command and send it to the central processing module. It should also be noted that the communication module can be used not only to obtain the analog signal detection command, but also for other types of communication interactions with external devices, such as data uploading and fault alarms.

[0040] In step S502 of some embodiments, the central processing module parses and processes the analog quantity detection command to determine the type of analog quantity to be detected and the detection configuration parameters, and sends the analog quantity type to the selection circuit. It should be noted that the types of analog quantities that can be detected in this application embodiment are diverse, including current signals, voltage signals, and temperature signals. The detection configuration parameters refer to the parameter information required for analog quantity detection. For example, when detecting an analog temperature signal, the detection configuration parameters can be set to adjust the central processing module to buffer mode, using the operational amplifier in the central processing module to adjust the impedance of the tested signal and buffer the signal about to be input to the analog-to-digital converter. As another example, when detecting an analog current signal, the detection configuration parameters can be set to adjust the central processing module to built-in feedback resistor mode (PGA mode), and the resistance value of the built-in feedback resistor can be set to 10K, 30K, 70K, or 150K according to the configuration of the PGA_GAIN register based on the detection configuration parameters. It should be understood that the selectable types of detection configuration parameters are diverse and may include, but are not limited to, the specific embodiments mentioned above.

[0041] It needs to be clarified that sending the analog signal type to the selection circuit aims to enable the selection circuit to select the corresponding output channel based on the analog signal type, thereby connecting the central processing module and the corresponding detection module. The analog signal type can be represented by a binary number; for example, 001 represents a temperature signal type, 011 represents a voltage signal detection type, and 101 represents a current signal detection type. In some more specific embodiments, the selection circuit may include an 8-to-1 analog switch (CD4 step S501 chip) connected to the positive terminal of an operational amplifier in the central processing module, while the negative terminal of the operational amplifier has two reserved voltage divider resistors. The analog switch (CD4 step S501 chip) can have three configurable selection channels: H1, H2, and H3. Different channels are selected through software configuration; for example, H1H2H3=001 corresponds to channel 1, H1H2H3=010 corresponds to channel 2, H1H2H3=011 corresponds to channel 3, ..., H1H2H3=111 corresponds to channel 8. In this way, the selection circuit can connect the central processing module and the corresponding detection module by using the analog quantity type represented by binary numbers.

[0042] In step S503 of some embodiments, when the analog quantity type is the first type, the central processing module and the first detection module are connected via a selection circuit, and the central processing module controls the first detection module to perform analog quantity detection of the first type according to the detection configuration parameters to obtain the first analog quantity detection value.

[0043] Reference Figure 6 According to some embodiments of the present invention, the first type of analog quantity detection is a current-type analog quantity detection. The central processing module includes an operational amplifier and a built-in feedback resistor, wherein the operational amplifier, in conjunction with the built-in feedback resistor, performs the first type of analog quantity detection. Step S503 involves the central processing module controlling the first detection module to perform the first type of analog quantity detection according to the detection configuration parameters, obtaining the first analog quantity detection value, which may include, but is not limited to: Step S601: The central processing module adjusts the resistance value of the built-in feedback resistor based on the detection configuration parameters to determine the current signal amplification gain. Step S602: Detect the analog quantity of current type based on the current signal amplification gain to obtain the first analog quantity detection value.

[0044] It should be noted that in some embodiments, the current signal detection terminal of the first detection module is connected to the non-inverting input terminal of the operational amplifier, the output port of the operational amplifier is connected to the analog-to-digital converter, and the built-in feedback resistor is placed between the output port and the inverting input terminal of the operational amplifier. After the current signal is detected at the current signal detection terminal, it is connected to the analog-to-digital converter via the output port to convert the analog current signal into a digital signal. Since the built-in feedback resistor is placed between the output port and the inverting input terminal of the operational amplifier, by adjusting the built-in feedback resistor, a fixed gain amplification effect can be achieved on the detected current signal. For example, the gain supported by the operational amplifier in conjunction with the built-in feedback resistor can be x2, x4, x8, or x16.

[0045] In some more specific embodiments, by adjusting the central processing module to the built-in feedback resistor mode (PGA mode), a fixed gain amplification effect can be achieved by adjusting the on-chip resistor values. Supported gains are x2, x4, x8, and x16, eliminating the need for external feedback resistors. In the built-in feedback resistor mode, based on the configuration of the PGA_GAIN register, the first built-in feedback resistor Rf has a value of 10K, 30K, 70K, or 150Kohm, and the second built-in feedback resistor R1 has a fixed value of 10Kohm. Therefore, the formula for calculating the in-phase gain in the built-in feedback resistor mode can be expressed as:

[0046] In this way, we can obtain in-phase amplification factors of x2, x4, x8, and x16 to achieve the gain supported by the above operational amplifier in conjunction with the built-in feedback resistor.

[0047] In the embodiments of this application shown in steps S601 to S602, the central processing module first adjusts the value of the built-in feedback resistor based on the detection configuration parameters to determine the current signal amplification gain. Then, based on the current signal amplification gain, the analog quantity of the current type is detected to obtain a first analog quantity detection value. It should be noted that the detection configuration parameters refer to the parameter information required for analog quantity detection. For example, when performing analog quantity detection of a current signal, the detection configuration parameters can be set to adjust the central processing module to the built-in feedback resistor mode (PGA mode), and the value of the built-in feedback resistor can be 10K, 30K, 70K, or 150K according to the configuration of the PGA_GAIN register based on the detection configuration parameters. It should be understood that the selectable types of detection configuration parameters are diverse and may include, but are not limited to, the specific embodiments mentioned above. Therefore, by adjusting the value of the built-in feedback resistor to determine the current signal amplification gain, and then detecting the analog quantity of the current type based on the current signal amplification gain, a first analog quantity detection value is obtained. In this way, the detection of the current signal and the determination of the first analog quantity detection value used to characterize the strength of the current signal can be achieved.

[0048] In step S504 of some embodiments, when the analog quantity type is the second type, the central processing module and the second detection module are connected via a selection circuit, and the central processing module controls the second detection module to perform analog quantity detection of the second type according to the detection configuration parameters to obtain the second analog quantity detection value.

[0049] Reference Figure 7 According to some embodiments of the present invention, the second type of analog quantity detection is a temperature-type analog quantity detection, and the central processing module includes an operational amplifier. Step S504 involves the central processing module controlling the second detection module to perform the second type of analog quantity detection according to the detection configuration parameters, obtaining a second analog quantity detection value, which may include, but is not limited to: Step S701: The central processing module controls the second detection module to perform analog quantity detection of temperature type according to the detection configuration parameters, and obtains the temperature detection value. In step S702, the temperature detection value is buffered by an operational amplifier to obtain the second analog detection value.

[0050] It should be noted that in some embodiments, the temperature signal detection terminal of the second detection module is connected to the non-inverting input terminal of the operational amplifier, the output port of the operational amplifier is connected to the analog-to-digital converter, and the output port of the operational amplifier is connected to its inverting input terminal. After the temperature signal detection terminal detects the ambient temperature, it is connected to the analog-to-digital converter via the output port to convert the analog temperature signal into a digital signal. The operational amplifier positioned between the temperature signal detection terminal and the analog-to-digital converter provides impedance adjustment for the analog-to-digital converter.

[0051] In the embodiments of this application shown in steps S701 to S702, the central processing module first controls the second detection module to perform analog quantity detection of temperature type according to the detection configuration parameters to obtain the temperature detection value. Then, the temperature detection value is buffered by the operational amplifier to obtain the second analog quantity detection value. It should be noted that the detection configuration parameters refer to the parameter information required for analog quantity detection. For example, when performing analog quantity detection of temperature signals, the detection configuration parameters can be set to adjust the central processing module to buffer mode, using the operational amplifier in the central processing module to adjust the impedance of the tested signal and buffer the signal about to be input to the analog-to-digital converter. In some embodiments, when the input signal frequency is compatible with the gain-bandwidth product (GBW) of the operational amplifier, the central processing module configured in buffer mode can enhance the temperature detection value through the operational amplifier, thereby improving the driving capability of the input signal of the analog-to-digital converter. Therefore, by controlling the second detection module to perform analog quantity detection of temperature type, obtaining the temperature detection value, and then buffering the temperature detection value through the operational amplifier, the second analog quantity detection value is obtained. In this way, the ambient temperature can be detected, and the second analog quantity detection value used to characterize the ambient temperature can be determined.
