It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further discussion thereof is necessary in subsequent figures.
The embodiment of the disclosure relates to a technical scheme of safe charging. Fig. 1 illustrates a block diagram of a charging method implemented by a charging power supply device, according to some embodiments. As shown in fig. 1, the method includes: step S1100 and step S1200.
Step S1100, a baseband signal carrying power identification information of the power module is obtained.
In this embodiment, the charging power supply device may be any device capable of supplying electric power and implementing the charging method of the embodiment of the present application. Taking an electric vehicle charging scene as an example, the charging modes of the electric vehicle include two modes of charging by a charging pile and charging by commercial power, and the charging power supply device can be set for all power supplies capable of realizing the two charging modes, or the charging power supply device can be set only for the charging pile, and the charging power supply device is not particularly limited.
Each charging power supply device can acquire a baseband signal carrying power supply identification information of a corresponding power supply module. The power supply identification information may be information of a geographical location where the power supply module is located, or information of power supply performance of the power supply module. The information of the power supply performance may be information such as charging voltage, charging current, charging power and the like provided by the power supply module.
Continuing with the above example, in an electric vehicle charging scenario, the geographic location of the charging stake is different from the geographic location of the utility power. The power supply performance of the charging pile is different from that of the commercial power. The power supply performance of the commercial power is generally 220v 50Hz alternating current. The power supply performance of the charging pile is generally higher than that of the commercial power. Therefore, the power supply identification information of the power supply module is different for two modes of charging the charging pile and charging the commercial power.
Step S1200, modulating the baseband signal into a modulated signal different from the power supply signal frequency of the power module, and outputting the modulated signal to a charging management device for charging pattern matching.
In this embodiment, since the low-frequency baseband signal cannot be used as the transmission signal, after the baseband signal carrying the power identification information of the power module is obtained, the low-frequency baseband signal is modulated into a modulated signal different from the frequency of the power supply signal of the power module. Wherein the frequency of the modulation signal is higher than the frequency of the supply signal. For example, the frequency of the modulated signal is 6MHz and the frequency of the power supply signal is 50HZ.
In the case where the charging power supply device is electrically connected to the charging management device, the charging power supply device may output the modulation signal to the charging management device. After receiving the modulation signal output by the charging power supply device, the charging management device demodulates and analyzes the modulation signal to obtain power supply identification information, and can perform charging mode matching according to the power supply identification information.
In an example in which both the utility power charging and the charging pile charging of the electric vehicle are provided with the charging power supply device, the charging power supply device may modulate the baseband signal carrying the power supply identification information of its power supply module into a modulation signal of 6MHz different from the frequency (50 HZ) of the power supply signal, and output the modulation signal to the charging management device. Because the power supply identification information of the charging pile and the commercial power are different, after receiving the modulation signal, the charging management device can determine whether the current charging mode is the charging pile charging or the commercial power charging according to the modulation signal, and then determine the corresponding charging mode. And under the condition that the current charging mode charges the charging pile, determining that the charging mode is a normal charging mode with unlimited capacity or unlimited current. And under the condition that the current charging mode is the mains supply charging, determining that the charging mode is a capacity-limiting or current-limiting charging mode.
In an example in which the charging pile of the electric vehicle is provided with the charging power supply device, if the charging management device can receive the modulation signal under the condition that the charging management device is connected with the power supply for charging, the connected power supply is determined to be the charging pile, and then the charging mode is determined to be a normal charging mode without current limitation or capacity limitation. If the charging management device cannot receive the modulation signal, the connected power supply is determined to be charged by the commercial power, and then a limited charging mode of limiting capacity or limiting current of the charging mode is determined.
According to the embodiment of the application, the baseband signal carrying the power supply identification information of the power supply module is obtained, wherein the power supply identification information is information representing the power supply performance or the geographic position of the power supply module, the baseband signal is modulated into the modulation signal which is different from the frequency of the power supply signal of the power supply module, and the modulation signal is output to the charging management device for carrying out charging mode matching, so that the charging mode matching based on the power supply identification information can be realized, the charging mode corresponding to the power supply identification information is further determined, and the charging safety is improved, thereby avoiding the safety problem caused by the existing indoor charging or 'flying line' charging environment.
In some embodiments, to reduce the power consumption of the charging power module, the outputting the modulated signal to the charging management device for charging pattern matching includes:
and outputting the modulation signal to a charging management device for charging mode matching every first preset time interval.
In this embodiment, the first preset duration may be an interval duration of transmitting the modulation signal. For example, the first preset time period may be 1s or 2s, and those skilled in the art will understand that specific values of the first preset time period are not limited herein.
In some embodiments, the acquiring the baseband signal carrying the power supply identification information of the power supply module includes:
receiving a signal output by the power supply module; the signals comprise a power supply signal and a baseband signal carrying power supply identification information of the power supply module; and isolating the baseband signal from the power supply signal to obtain a baseband signal carrying the power supply identification information of the power supply module.
In this embodiment, the charging power supply device receives a power supply signal output by the power supply module and a baseband signal carrying power supply identification information of the power supply module, where the power supply signal output by the power supply module affects modulation of the baseband signal. In order to isolate the influence of the power supply signal, after receiving the power supply signal and the baseband signal output by the power supply module, isolating the baseband signal from the power supply signal to obtain the baseband signal carrying the power supply identification information of the power supply module.
Fig. 2 illustrates a block diagram of a charging method implemented by a charging management device, according to some embodiments. As shown in fig. 2, the method includes steps S2100 to S2400.
In step S2100, a modulated signal output from the charging power supply device is received.
In this embodiment, when the charging management device is electrically connected to the charging power supply device, the charging management device receives the modulation signal output from the charging power supply device. Wherein the modulation signal modulates a baseband signal carrying power supply identification information of a power supply module of the charging power supply device. The power supply identification information is information for identifying the power supply performance or the geographic position of the power supply module.
Step S2200, demodulating the modulated signal to obtain a baseband signal carrying the power supply identification information of the power supply module.
In this embodiment, the charging management device demodulates the high-frequency modulation signal to obtain a low-frequency baseband signal carrying the power supply identification information of the power supply module.
Step S2300, analyzing the baseband signal into the power supply identification information, and matching the power supply identification information with preset power supply information, where the preset power supply information is information reflecting the power supply performance or the geographic position of the normal charging mode.
In this embodiment, the low-frequency baseband signal is parsed to obtain the power supply identification information, and the power supply identification information is matched with the preset power supply information to determine whether the power supply identification information meets the normal charging requirement. The preset power information may be a power supply performance reflecting a normal charging mode. The power supply capability may include at least one of voltage, current, power, etc. The power supply performance can be set according to the capacity and the charging requirement of the battery module, and can also be set by the charging conditions agreed by the charging power supply device and the charging management device, and those skilled in the art should understand that the specific setting mode of the power supply performance is not limited herein.
The preset power information may also be information reflecting the geographical location of the normal charging mode. The geographical location information may be location information of an outdoor charging pile, or may be agreed location information of other safe charging, which is not specifically limited herein.
Step S2400, determining a charging mode of the battery module according to the matching result.
In some embodiments, the step S2400 determines the charging mode of the battery module according to the matching result, including the steps S2411 and S2412.
Step S2411, determining that the charging mode of the battery module is a limited charging mode if the matching result is that the power supply identification information is not matched with the preset power supply information.
Step S2412, determining that the charging mode of the battery module is the normal charging mode if the matching result is that the power supply identification information matches with the preset power supply information.
In this embodiment, when the matching result is that the power supply identification information matches with the preset power supply information, it is described that the charging power supply device currently connected to the charging management device meets the normal charging requirement, and it is determined to charge the battery module in the normal charging mode. The normal charging mode is an unlimited-current or unlimited-capacity charging mode. And under the condition that the matching result is that the power supply identification information is not matched with the preset power supply information, the fact that the charging power supply device connected with the charging management device at present does not meet the normal charging requirement is indicated, and the battery module is determined to be charged in the limited charging mode. The limited charging mode is at least one of current limiting and capacity limiting.
In some embodiments, after performing step S2411 to determine that the charging mode of the battery module is the limited charging mode, the method further includes step S3100 and step S3200.
In step S3100, if the detected voltage value of the battery module is smaller than the set voltage threshold, charging of the battery module is maintained.
Step S3200, when the detected voltage value of the battery module is greater than or equal to the set voltage threshold value, the battery module is charged.
In this embodiment, after determining that the charging mode of the battery module is the limited charging mode, the voltage value of the battery module is detected, so as to determine whether the voltage of the current battery module reaches the set voltage threshold according to the detected voltage value of the battery module.
And when the detected voltage value of the battery module is smaller than the set voltage threshold value, the battery module is kept charged. And ending the charging of the battery module under the condition that the detected voltage value of the battery module is greater than or equal to the set voltage threshold value.
According to the embodiment of the application, after the charging mode of the battery module is determined to be the limited charging mode, the battery module is kept charged under the condition that the detected voltage value of the battery module is smaller than the set voltage threshold value, and the charging of the battery module is ended under the condition that the detected voltage value of the battery module is larger than or equal to the set voltage threshold value, so that the charging start and stop of the battery module can be automatically controlled based on the voltage value of the battery module under the limited charging mode, and the charging safety is further improved.
In some embodiments, the method further comprises step S4100 and step S4200 before performing step S2100 to receive the modulated signal output by the charging power device.
In step S4100, every second preset time period, it is detected whether a modulation signal output by the charging power supply device is received.
In step S4200, when the modulation signal output by the charging power supply device is not received, it is determined that the charging mode of the battery module is the limited charging mode.
In this embodiment, the charging management device detects whether the modulation signal output by the charging power supply device is received or not every second preset time period, and determines that the charging mode of the battery module is the limited charging mode when the modulation signal output by the charging power supply device is not received. The second preset time length is a preset detection period.
In some embodiments, the first preset duration and the second preset duration are the same value. For example, 1s or 2s.
In other embodiments, the first preset duration and the second preset duration are different values. For example, the first preset duration is 2s, and the second preset duration is 4s.
In some embodiments, after performing step S4200 to determine that the charging mode for the battery module is the limited charging mode, the method further includes steps S5100 and S5200.
In step S5100, when a modulated signal output from the charging power supply device is received, a charging mode of the battery module is redetermined according to the modulated signal.
Step S5200, when the redetermined charging mode does not coincide with the limited charging mode, switching the charging mode to the battery module to the redetermined charging mode.
In this embodiment, after executing step S4200 to determine that the charging mode of the battery module is the limited charging mode, if the modulation signal output by the charging power device is received, steps S2100 to S2400 are executed to re-determine the charging mode of the battery module. The execution of steps S2100 to S2400 has been described in detail above, and will not be repeated here.
After the charging mode is re-determined, it is detected whether the re-determined charging mode is a limited charging mode. In the case where the re-determined charging mode is the normal charging mode, the charging mode to the battery module is switched to the normal charging mode.
In some embodiments, after performing step S5100, the method further comprises:
and when the redetermined charging mode is consistent with the limit charging mode, maintaining the charging mode of the battery module as the limit charging mode.
According to the embodiment of the application, after the charging mode of the battery module is determined to be the limited charging mode, under the condition that the modulation signal output by the charging power supply device is received, the charging mode of the battery module is redetermined according to the modulation signal, whether the redetermined charging mode is the limited charging mode is detected, and under the condition that the redetermined charging mode is inconsistent with the limited charging mode, the charging mode of the battery module is switched to be the redetermined charging mode, so that corresponding charging mode adjustment based on a real-time detection result can be realized, and charging safety is improved.
