Example 1
According to an embodiment of the present invention, there is provided a method of monitoring a vehicle battery, it being noted that in the flow chart of the accompanying drawings, the steps shown therein may be performed in a computer system such as a set of computer executable instructions, and that although a logical sequence is shown in the flow chart, in some cases the steps shown or described may be performed in a different order than herein.
The following describes a method for monitoring a vehicle battery according to an embodiment of the present invention.
Fig. 1 is a flowchart of a method for monitoring a vehicle battery according to an embodiment of the present invention, as shown in fig. 1, the method may include the steps of:
step S101, in response to receiving the wake-up signal, controlling the vehicle in the sleep state to enter a power-on running state.
In the technical solution provided in the above step S101 of the present invention, when the vehicle is in the sleep state, the vehicle in the sleep state may be controlled to enter the power-on running state, that is, wake up the vehicle in the sleep state, in response to the received wake-up signal.
In this embodiment, the wake-up signal may be from a wake-up source, alternatively, this embodiment may provide a variety of wake-up sources that may be used to effect thermal runaway monitoring during vehicle dormancy. Optionally, the plurality of wake sources may include, but are not limited to, at least one of: ignition switch (IG), electric vehicle control area network communication (Electric Vehicle Control Area Network, EVCAN), battery voltage temperature monitor, pressure sensor (Barometric Pressure Sensor, BPS), smoke sensor (Building Automation System, BAS), timer (Real-time clock, RTC). The Wake-up signal sent by the ignition switch IG may be an ignition key control signal (Klemme 15, abbreviated as KL 15), the Wake-up signal sent by the communication EVCAN may be a control area network communication Wake-up signal (Control Area Network Wake, can_wake), the Wake-up signal sent by the battery voltage temperature monitor may be a serial peripheral interface Wake-up signal (Serial Peripheral Interface Wake, abbreviated as isospi_wake), the Wake-up signal sent by the pressure sensor BPS may be a pressure sensor Wake-up signal (Barometric Pressure Sensor Wake, abbreviated as bps_wake), the Wake-up signal sent by the smoke sensor BAS may be a smoke sensor Wake-up signal (Building Automation System Wake, abbreviated as bas_wake), and the Wake-up signal sent by the RTC timer may be a timer Wake-up signal (Real-time clock Wake, abbreviated as rtc_wake). When the above wake-up signal is received, the vehicle in the sleep state may be waken, that is, the vehicle is controlled to be switched from the sleep state to the power-on running state.
In this embodiment, if a wake-up signal transmitted to any one of the above-described plural wake-up sources is responded, the vehicle in the sleep state may be controlled to enter the power-on running state.
Step S102, a sending module for sending a wake-up signal in the vehicle is determined in response to the vehicle entering a power-on running state.
In the technical solution provided in the above step S102 of the present invention, after controlling the vehicle in the sleep state to enter the power-on running state in response to receiving the wake-up signal, the transmitting module for transmitting the wake-up signal in the vehicle may be determined in response to the vehicle entering the power-on running state.
In this embodiment, when the vehicle enters the power-on running state, a transmission module for transmitting a wake-up signal in the vehicle may be further determined, where the transmission module may be a first type transmission module for starting the vehicle or a second type transmission module for monitoring a characteristic parameter of a battery of the vehicle.
In this embodiment, the first type of transmission module is used to start the vehicle, wherein the first type of transmission module comprises at least an ignition switch module and a communication module; the ignition switch module can be an ignition switch IG and the communication module can be a communication EVCAN; the second type sending module is used for monitoring characteristic parameters of the vehicle battery, and at least comprises a timer module, an atmospheric pressure sensor module, a smoke sensor module and a battery sampling module; the timer module may be an RTC timer, the atmospheric pressure sensor module may be a pressure sensor BPS, the smoke sensor module may be a smoke sensor BAS, and the battery sampling module may be a battery voltage temperature monitor.
For example, after the vehicle enters a power-on running state, a sending module that sends a wake-up signal may be determined; as can be seen from the foregoing description, the wake-up signal is transmitted by different transmitting modules (e.g., wake-up sources), and based on this, the module type for transmitting the wake-up signal can be determined according to the received identity of the wake-up signal. For example, when the Wake-up signal is a can_wake signal, the transmitting module for confirming that the Wake-up signal is transmitted is a communication EVCAN module, and the transmitting module is a first type transmitting module; when the Wake-up signal is a bps_wake signal, the transmitting module for confirming the transmission of the Wake-up signal is a pressure sensor BPS module, and the transmitting module is a second type transmitting module.
In this embodiment, the type of transmitting module may be determined from the wake-up signal if it is responsive to the vehicle entering a powered-up operational state.
Step S103, determining a battery state of the vehicle battery based on the module type of the transmission module and the characteristic parameter of the vehicle battery.
In the technical scheme provided in the step S103, after the response and the vehicle enter the power-on running state and the type of the transmitting module for transmitting the wake-up signal in the vehicle is determined, the characteristic parameters of the vehicle battery can be obtained, and the battery state of the vehicle battery is determined based on the type of the transmitting module and the characteristic parameters of the vehicle battery.
In this embodiment, if the module type of the transmission module is the first module type, the vehicle battery may be in a low-battery state or in a thermal runaway state, and if the module type of the transmission module is the second module type, the vehicle battery is in a thermal runaway state, based on which, after determining the module type of the transmission module, the characteristic parameter of the vehicle battery may be obtained, and further, the battery state of the vehicle battery may be determined based on the characteristic parameter of the vehicle battery.
In this embodiment, the battery parameters of the vehicle include at least: monomer voltage, battery temperature, battery pack atmospheric pressure, smoke concentration in the battery pack, and the like; based on this, after the characteristic parameter of the vehicle battery is acquired, it may be further determined that the battery state of the vehicle battery is an abnormal state.
For example, if the module type of the sending module is an ignition switch module, that is, if the sending module is of a first type and the cell voltage in the characteristic parameter of the vehicle battery is lower than a first voltage threshold, determining that the vehicle battery is in a low battery state, wherein the first voltage threshold may be 10V; if the module type of the transmission module is a first module type and the cell voltage in the characteristic parameter of the vehicle battery is lower than a second voltage threshold, which may be 8V, for illustrative example only, specific values of the first voltage threshold and the second voltage threshold are not limited, the vehicle battery state is determined to be a thermal runaway state.
For example, if the module type of the transmission module is a timer module, that is, the transmission module is of the second type, then when any one of the characteristic parameters of the vehicle battery is outside of its corresponding parameter threshold range, then it is determined that the vehicle battery is in a thermal runaway state.
In this embodiment, it may be determined that the vehicle battery is in a low-battery state or a thermal runaway state according to the module type of the transmission module and the characteristic parameters of the vehicle battery.
Step S104, in response to the battery state being a thermal runaway state, a prompt message is generated.
In the technical solution provided in the above step S104 of the present invention, in the determination that the vehicle battery is in the thermal runaway state based on step S103, the prompt information may be generated, where the prompt information may be used to prompt the riding object of the vehicle of the abnormality of the vehicle battery.
For example, when the vehicle battery is in a thermal runaway state, an alarm prompt may be played, or an alarm prompt symbol may be displayed on the meter to alert the occupant that the vehicle battery is in a thermal runaway state, which is only an exemplary illustration herein, and may alert the occupant that the vehicle battery is in a thermal runaway state in other manners.
In this embodiment, in response to the battery state of the vehicle being a thermal runaway state, a presentation message is generated to present a battery abnormality of the vehicle to a riding object of the vehicle.
In the invention, the steps S101 to S104 are performed, and the wake-up signal received when the vehicle is in the dormant state can wake up the vehicle in the dormant state to enter the power-on running state; after the vehicle enters a power-on running state, the type of a wake-up source for waking up the vehicle can be further determined; according to different awakening sources and characteristic parameters of a vehicle battery, the battery state of the vehicle battery can be determined, when the battery state of the vehicle is in a thermal runaway state, prompt information can be generated and sent to a riding object of the vehicle, so that the purposes of accurately identifying a battery thermal runaway event and timely reminding the riding object of the vehicle are achieved, the technical problem that the vehicle cannot monitor the battery thermal runaway in a power-down sleep state is solved, and the technical effect that the battery thermal runaway monitoring can be performed when the vehicle is in the power-down sleep state is achieved.
It should be noted that the above embodiments may be performed by a battery thermal runaway monitoring system.
The above-described method of this embodiment is further described below.
As an optional embodiment, step S102, in response to the vehicle entering a power-on running state, determines a transmitting module for transmitting a wake-up signal in the vehicle, including: acquiring interface information for receiving a wake-up signal, wherein the interface information is used for indicating interface identifiers of interfaces for receiving the wake-up signal, the interface identifiers at least comprise a first identifier and a second identifier, the first identifier is used for identifying an interface of a first type sending module for sending the wake-up signal, and the second identifier is used for identifying an interface of a second type sending module for sending the wake-up signal; responding to the interface identifier as a first identifier, and determining that the sending module of the wake-up signal is a first type sending module; and responding to the interface identifier as a second identifier, and determining that the sending module of the wake-up signal is a second type sending module.
In this embodiment, the interface identifier of the interface receiving the wake-up signal may be a first identifier or a second identifier, where the first identifier includes an Input/Output interface 1 (Input/Output 1, abbreviated as io_1), the second identifier includes an Input/Output interface 2 (Input/Output 2, abbreviated as io_2) and an Input/Output interface 3 (Input/Output 3, abbreviated as io_3), based on which, when the vehicle is in a power-on running state, interface information receiving the wake-up signal may be acquired, where the interface information includes the interface identifier, and further based on the interface identifier, a module type of a transmitting module transmitting the wake-up signal is further determined.
In this embodiment, as can be seen from the foregoing description, the module type of the transmission module may be a first type transmission module or a second type transmission module; when the interface identifier of the interface of the received wake-up signal is determined to be a first identifier, the module type of the sending module of the wake-up signal can be determined to be a first type sending module, when the interface identifier of the interface of the received wake-up signal is determined to be a second identifier, the module type of the sending module of the wake-up signal is determined to be a second type sending module, and after the sending module of the wake-up signal is determined, the characteristic parameters of the vehicle battery can be obtained.
For example, when the vehicle is in a power-on running state, and the interface identifier of the interface of the acquired wake-up signal is io_1, determining that the interface identifier type of the interface of the received wake-up signal is a first identifier, and further determining that the module type of the sending module is a first type sending module; when the vehicle is in a power-on running state, the interface identifier of the interface of the acquired wake-up signal is IO_2, the interface identifier type of the interface of the received wake-up signal is determined to be a second identifier, and then the module type of the sending module is determined to be a second type sending module.
For example, when the Wake-up signal received by the vehicle is a can_wake signal, since the can_wake signal is transmitted through the io_1 interface, based on this, it may be determined that the interface identifier of the interface of the can_wake signal is io_1, and since the module type of the transmitting module corresponding to the io_1 interface identifier is the first type transmitting module, based on this, it may be determined that the transmitting module that transmits the can_wake signal is the first type transmitting module.
In this embodiment, the module type of the transmitting module of the wake-up signal of the vehicle may be determined to be the first module type or the second module type according to the interface identifier of the interface of the wake-up signal in response to the power-on running state of the vehicle.
As an alternative embodiment, step S103, determining the battery state of the vehicle battery based on the module type of the transmitting module and the characteristic parameter of the vehicle battery, includes: responding to the transmitting module as the first type transmitting module, and acquiring characteristic parameters of a vehicle battery; in response to the characteristic parameter abnormality, it is determined that the battery state of the vehicle battery is a low-battery state or a thermal runaway state.
In this embodiment, based on the wake-up signal sent by the first type of sending module and the characteristic parameter of the vehicle battery, the battery state of the vehicle battery may be determined, where the battery state of the vehicle may be a low battery state or a thermal runaway state, and the battery parameters of the vehicle may include, but are not limited to: cell voltage, battery temperature, battery pack atmospheric pressure, smoke concentration in the battery pack, and the like. After the characteristic parameters of the vehicle battery are obtained, the obtained characteristic parameters can be compared with the parameter threshold value, so that whether the characteristic parameters of the vehicle battery are abnormal or not can be determined.
Optionally, a single voltage threshold, a battery temperature threshold, a battery pack atmospheric pressure threshold, a smoke concentration threshold in the battery pack, and the like are set in advance, based on which, after the characteristic parameter of the vehicle battery is obtained, the characteristic parameter of the vehicle battery can be compared with the set corresponding threshold, so as to determine whether the characteristic parameter of the vehicle battery is abnormal, for example, when the module type of the transmitting module is the first type transmitting module, the single voltage of the vehicle battery obtained is greater than the single voltage threshold set in advance, and the characteristic parameter of the vehicle battery can be determined to be abnormal.
For example, if the module type of the sending module is the first type, for example, the module type of the sending module is an ignition switch module, and the single voltage in the characteristic parameter of the vehicle battery is lower than a first voltage threshold, it is determined that the vehicle battery is in a low battery state, where the first voltage threshold may be 10V; if the module type of the transmission module is a first module type and the cell voltage in the characteristic parameter of the vehicle battery is lower than a second voltage threshold, which may be 8V, for illustrative example only, specific values of the first voltage threshold and the second voltage threshold are not limited, the vehicle battery state is determined to be a thermal runaway state.
In this embodiment, in response to the module type of the transmission module being the ignition switch module, that is, when the transmission module is the first type transmission module, the characteristic parameter of the vehicle battery may also be obtained; when the characteristic parameter is abnormal, it may be further determined that the battery state of the vehicle battery is a low-battery state or a thermal runaway state.
As an alternative embodiment, step S103, determining the battery state of the vehicle battery based on the module type of the transmitting module and the characteristic parameter of the vehicle battery, includes: responding to the sending module as a second type sending module, and acquiring characteristic parameters of a vehicle battery; in response to the characteristic parameter abnormality, it is determined that the battery state of the vehicle battery is a thermal runaway state.
In this embodiment, the battery state of the vehicle battery may be determined to be a thermal runaway state based on the wake-up signal sent by the second type sending module and the characteristic parameters of the vehicle battery, which may include, but are not limited to: cell voltage, battery temperature, battery pack atmospheric pressure, smoke concentration in the battery pack, and the like. Based on this, after receiving the wake-up signal sent by the second type sending module, it may be further determined whether the characteristic parameter of the vehicle battery is abnormal, that is, the characteristic parameter of the vehicle battery may be compared with a parameter threshold, and if the characteristic parameter exceeds the parameter threshold, it may be determined that the battery state of the vehicle battery is a thermal runaway state.
For example, if the type of the transmission module is the second type, for example, if the module type of the transmission module is a timer module, then when any one of the characteristic parameters of the vehicle battery is outside of its corresponding parameter threshold range, it is determined that the vehicle battery is in a thermal runaway state.
In this embodiment, in response to the module type of the transmission module being the second type transmission module, the characteristic parameter of the vehicle battery may also be acquired; when the characteristic parameter is abnormal, it may be further determined that the battery state of the vehicle battery is a thermal runaway state.
As an optional embodiment, in step S103, a method for monitoring a vehicle battery further includes: and determining that the characteristic parameter of the vehicle battery is abnormal in response to the characteristic parameter of the vehicle battery being outside the characteristic parameter threshold range.
In this embodiment, when determining whether the characteristic parameter of the vehicle battery is abnormal, the obtained characteristic parameter of the vehicle battery may be compared with the characteristic parameter threshold value, and if the obtained characteristic parameter of the vehicle battery is outside the characteristic parameter threshold value range, it is determined that the characteristic parameter of the vehicle battery is abnormal.
For example, the obtained battery temperature of the vehicle battery is 85 ℃, the battery temperature threshold range is-20 ℃ to 60 ℃, and since 85 ℃ is not within-20 ℃ to 60 ℃, the vehicle battery temperature is determined to be outside the battery temperature threshold range based on the battery temperature threshold range, and further the battery temperature of the vehicle battery is determined to be abnormal, which is only an exemplary example and not limiting on the specific value of the vehicle battery temperature.
In this embodiment, the characteristic parameter of the vehicle battery is compared with the characteristic parameter threshold value, and in response to the characteristic parameter of the vehicle battery being outside the characteristic parameter threshold value range, the characteristic parameter abnormality of the vehicle battery may be further determined.
