Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function. The embodiments described below with reference to the drawings are illustrative and are intended to be illustrative of the invention and should not be construed as limiting the invention.
The vehicle-mounted inverter 10 according to the first aspect of the invention is described in further detail with reference to fig. 1 and 2. First, as shown in fig. 1, the vehicle-mounted inverter 10 is connected to a vehicle-mounted battery 11 and a vehicle body control module 12, respectively. Specifically, as shown in fig. 2, the vehicle-mounted inverter 10 includes an inverter control circuit 101 and an inverter host 102, wherein the inverter control circuit 101 is connected to a vehicle body control module 12 through a LIN bus, and the vehicle body control module 12 is configured to receive a command input by a user through a control screen 13 in a driving computer and transmit the command to the inverter control circuit 101 through the LIN bus, so as to set an application mode of the inverter host 102 according to the transmitted command.
After the user connects the vehicle-mounted inverter 10 to the vehicle-mounted battery 11 and the vehicle body control module 12, respectively, if the user only needs the normal operation of the vehicle-mounted inverter to supply power to the low-power electrical equipment (for example, to charge a mobile phone, etc.), the user can select a normal application mode option at the central control panel 13, the vehicle body control module 12 receives the user input and then sends an instruction for setting the normal application mode to the inverter control circuit 101 through the LIN bus, and the inverter control circuit 101 sets the inverter main machine 102 to operate normally and output voltage according to the received instruction, that is, the vehicle-mounted inverter enables the normal application mode (for example, calls and runs a program related to the normal application mode).
If a user drives to travel or camp on the vehicle by himself, high-power electrical equipment such as electric heating products and the like may need to be used in cold weather or overnight, however, the operation power of the electrical equipment usually exceeds the maximum power of the vehicle-mounted inverter, so that the vehicle-mounted inverter is subjected to overload protection and stops voltage output and cannot be used. However, in the case of using the vehicle-mounted inverter according to the first aspect of the present invention, when a similar situation of accessing to the high-power electrical equipment is encountered, the user may select the power-limiting application mode option at the central control panel 13, the vehicle body control module 12, after receiving the user input, will send a command for setting the power-limiting application mode and transmit the command to the inverter control circuit 101 through the LIN bus, and the inverter control circuit 101 will set the inverter main machine 102 to temporarily supply power to the electrical equipment exceeding the maximum power of the vehicle-mounted inverter in a form not exceeding the maximum power thereof according to the received command, i.e., make the vehicle-mounted inverter enable the power-limiting application mode (e.g., call and run a program related to the power-limiting application mode). Specifically, after the limited power application mode is enabled, the output voltage can be automatically reduced so as to reduce the output power to be less than the maximum power value of the vehicle-mounted inverter, which enables electrical equipment such as electric heating products which cannot be used due to large power to be temporarily used, so that the use range of the vehicle-mounted inverter is expanded, which is particularly important for vehicle-mounted outgoing situations.
If any fault occurs in the conventional vehicle-mounted inverter, even if the fault is not serious, such as undervoltage or overheating, the working output of the vehicle-mounted inverter is stopped, the work can not be recovered until the fault disappears, and the recovery value has a return difference compared with the action value. However, when the vehicle-mounted inverter according to the first aspect of the present invention is used, and the vehicle body control module 12 receives the user input and transmits an instruction for setting the emergency application mode to the inverter control circuit 101 through the LIN bus when the user fails to stop the operation, the user may select the emergency application mode option at the center control panel 13, and the inverter control circuit 101 sets the inverter main unit 102 to the recovery operation, that is, the vehicle-mounted inverter enables the emergency application mode (for example, calls and runs a program related to the emergency application mode) when the inverter main unit is determined to be operable under the fault (for example, determined to be a non-serious fault) according to the received instruction. Specifically, after the emergency application mode is started, the working output voltage of the vehicle-mounted inverter can be recovered for non-serious faults such as undervoltage, overheating and the like, so that the working margin of the vehicle-mounted inverter is expanded on the premise of safety, and help is provided for emergency situations such as mobile phone charging contact rescue and the like, which is particularly important for vehicle-mounted outgoing situations.
The inverter control circuit in the vehicle-mounted inverter is connected with the vehicle body control module (namely, the vehicle body control module is a master device, and the vehicle-mounted inverter is a slave device) by configuring the LIN bus, so that a user can actively and flexibly set/select/switch corresponding application modes according to the self requirement and/or scenes through various vehicle-mounted inverter application mode options of a control screen in a traveling computer, and the use convenience and the user experience of the vehicle-mounted inverter are improved.
Additionally or alternatively, the inverter control circuit 101 may be configured to be able to set the operation of the inverter main machine 102 in a mode that is separate from the vehicle body control module 12, i.e., an offline application mode. For example, if the connection of the inverter control circuit 101 to the vehicle body control module 12 through the LIN bus is interrupted, the inverter control circuit 101 can cause the inverter host 102 to maintain the current application mode without suddenly stopping the operation of the vehicle-mounted inverter due to the interruption of the connection to the vehicle body control module.
Additionally or alternatively, in an optional implementation manner of the vehicle-mounted inverter according to the first aspect of the present invention, the inverter control circuit 101 may be further configured to collect status information of the inverter host 102, where the status information may include, but is not limited to, a warning that the inverter host is working normally or in a fault (such as under-voltage/over-voltage, overheating, over-current, short-circuit, poor insulation, internal fault, configuration error, etc.), sending load power, internal temperature, history record, product factory information, etc., and transmit the collected status information to the vehicle body control module 12 through the LIN bus so that a user can know a real-time status of the current vehicle-mounted inverter through the central control screen 13, thereby implementing status monitoring on the vehicle-mounted inverter. For example, when the central control panel 13 displays the failure warning information, if the failure warning information is non-critical failure warning information such as undervoltage, overheating, etc., the user can know that he can set the emergency application mode according to the actual situation or need; if the fault warning information is serious fault warning information such as short circuit, a user can know that the current vehicle-mounted inverter is inoperable and even further detection or maintenance is possibly needed; this makes it possible to further enhance the interaction between the user and the vehicle-mounted inverter, thereby further improving the convenience of use and user experience of the vehicle-mounted inverter.
A first embodiment of the vehicular electric power source system 20 according to the second aspect of the invention is described in further detail with reference to fig. 3A and 4. First, as shown in fig. 3A, the vehicle-mounted power supply system 20 includes a vehicle-mounted inverter 21 and an ac outlet 22, wherein ten lines are connected between the vehicle-mounted inverter 21 and the ac outlet 22; specifically, two lines for connecting the socket identification element in the ac socket to the signal input terminal of the inverter control circuit 211 are included; the system comprises two lines for connecting a micro-switch in an alternating current socket to a vehicle-mounted inverter, wherein one line connects a first end of the micro-switch to a signal input end of an inverter control circuit, and the other line connects a second end of the micro-switch to a signal public end of the inverter control circuit; the LED lamp control system comprises three lines for connecting a first LED lamp and a second LED lamp in an alternating current socket to a vehicle-mounted inverter, wherein two lines connect anodes of the first LED lamp and the second LED lamp to a signal output end of an inverter control circuit, and the other line connects a cathode common end of the two LED lamps to a signal common end of the inverter control circuit; two lines are included for connecting the ac outlet to the voltage output of the inverter main 212; and a line for connecting the PE terminal (protection ground) of the ac outlet to the negative electrode of the vehicle-mounted battery. Wherein the two lines for socket identification element connection form the identification signal input line of fig. 4, the two lines for microswitch connection form the switch signal input line of fig. 4, and the three lines for LED lamp connection form the switch signal output line of fig. 4.
In the first embodiment, the signals 00, 01, 10 and 11 can be combined by providing an open/short circuit on a printed circuit board built in the ac socket 22, and the inverter control circuit 211 determines whether the ac socket 22 is successfully connected to the voltage output terminal of the inverter main unit 212 or whether the type of the connected ac socket 22 is adapted to the voltage output by the inverter main unit according to the different received combined signals. For example, if inverter control circuit 211 receives a signal (e.g., signal 11) indicating that an ac outlet is not connected (e.g., a virtual connection condition may occur such that the ac outlet is not actually connected to the inverter main unit) to the voltage output of the inverter main unit, inverter main unit 212 is not enabled even if other conditions are met; for example, if the inverter control circuit 211 receives a signal (e.g., signal 00) indicating the type of ac outlet (e.g., chinese standard type) and determines that the inverter main unit 212 is of the american standard type outputting a voltage of 110V/60Hz, the inverter main unit 212 is not activated even if other conditions are satisfied.
When the inverter control circuit 211 receives a signal (e.g., signal 00) indicating the type of the ac socket (e.g., chinese standard type) and determines that the inverter host 212 is also a chinese standard type outputting a voltage of 220V/50Hz, at this time, the micro switch in the ac socket is turned on when the electrical equipment is connected (i.e., the plug of the electrical equipment is inserted into the ac socket), the inverter control circuit receives a low level signal to start the inverter host to operate to supply power to the connected electrical equipment, and at the same time, the inverter control circuit outputs a high level signal to turn on the first LED lamp (e.g., green lamp) to indicate that the vehicle-mounted inverter has normally operated; however, if the vehicle-mounted inverter fails, the inverter control circuit may output a pulse signal to cause the second LED lamp (e.g., red lamp) to blink. After the plug is pulled out of the alternating current socket, the micro switch in the alternating current socket is switched off, the inverter control circuit receives a high level signal so as to turn off the inverter host machine to work, and meanwhile, the inverter control circuit outputs a low level signal without lighting the LED lamp.
However, it should be understood that this embodiment may also employ more (e.g., 3) lines for socket identification, and thus may form more combinations.
A second embodiment of the vehicular electric power source system 20 according to the second aspect of the invention is described in further detail with reference to fig. 3B and 4. First, as shown in fig. 3B, the vehicle-mounted power supply system 20 includes a vehicle-mounted inverter 21 and an ac socket 22, wherein nine lines are connected between the vehicle-mounted inverter 21 and the ac socket 22; it differs from the first embodiment in that: the number of lines for socket identification element connection is one, i.e., one line for socket identification element connection forms the identification signal input line in fig. 4.
In the second embodiment, different resistance values are set on the printed circuit board built in the ac socket 22, and the pull-up resistor and the pull-down resistor in the inverter control circuit form a voltage dividing circuit, and then the single chip microcomputer performs a/D conversion sampling, wherein different voltage values are identified as corresponding to different ac socket types. For example, if inverter control circuit 211 receives a voltage value (e.g., approaching an a/D sampling reference circuit such as +5V) indicating that an ac outlet is not connected (e.g., a virtual connection condition may occur such that the ac outlet is not actually connected to the inverter main unit) to the voltage output of the inverter main unit, inverter main unit 212 is not enabled even if other conditions are met; for example, if the inverter control circuit 211 receives a voltage value indicating an ac outlet type (e.g., chinese standard type) and determines that the inverter main unit 212 is of the american standard type outputting a voltage of 110V/60Hz, the inverter main unit 212 is not started to operate even if other conditions are satisfied.
According to the vehicle-mounted power supply system of the second aspect of the present invention, the socket identification code is configured in the ac socket, so that the inverter control circuit in the vehicle-mounted inverter and the ac socket can interact locally, that is, the inverter control circuit receives a code (for example, the above-mentioned combined signal or voltage value) indicating that the socket is not connected or a code (for example, the above-mentioned combined signal or voltage value) indicating the type of the socket and determines whether the socket is adapted to the inverter host, so as to automatically detect the connection adaptation condition of the ac socket, and the inverter host is not started to operate the output voltage when the connection adaptation has an error, thereby realizing error prevention to enhance the safety of the system (ac socket) in use.
Further, the vehicle-mounted inverter according to the first aspect of the invention may be used in combination with the vehicle-mounted power supply system according to the second aspect of the invention. For example, when the signal received by the inverter control circuit indicates that the ac socket is not connected to the voltage output terminal of the inverter main unit or detects that the type of the ac socket connected to the voltage output terminal of the inverter main unit is not adapted to the inverter main unit, the connection error warning message may be transmitted to the vehicle body control module through the LIN bus so that the user may know that the ac socket is connected to the adaptation error through the central control panel and correct the error. This makes can further strengthen the interaction between the user and the on-vehicle inverter to the convenience of use and the user experience of on-vehicle inverter have further been promoted.
While embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and not to be construed as limiting the present invention, and that combinations, variations, modifications, substitutions and alterations of the above embodiments may be made by those of ordinary skill in the art within the scope of the present invention.
