Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
In order to solve the problems that a storage battery state detection method in the related art is complex and an owner cannot timely learn the health state of the storage battery, the disclosure provides a vehicle-mounted storage battery state detection method, a device, a readable storage medium and a vehicle. Referring to fig. 1, fig. 1 is a flow chart illustrating a method for detecting a state of an on-board battery according to an exemplary embodiment, which may be applied to an electronic device with processing capability, such as a vehicle control unit, a battery management unit, or an on-board dedicated processor in an on-board infotainment system. The following describes the embodiments of the present disclosure in detail by taking the electronic device as a vehicle control unit as an example. As shown in fig. 1, the method may include the following steps.
In S101, upon detection of a vehicle start signal, battery history state information during a vehicle history start process is acquired.
In the present disclosure, the state information of the battery during the start of the vehicle may be stored in a storage unit in the vehicle. The historical state information of the storage battery is used for representing the state information of the storage battery in the starting process of the vehicle before the vehicle is started at this time. The historical state information of the storage battery can comprise historical voltage values of the storage battery and/or historical state of charge.
Specifically, the state information of the battery may be collected by a battery sensor, such as a battery level sensor, a battery voltage sensor, or other devices capable of detecting a voltage value and/or a state of charge of the battery, which is not limited in this disclosure.
For example, during vehicle startup, the state of charge of the battery may be detected by a battery charge sensor mounted on the vehicle, and the detected state of charge of the battery may be transmitted to the vehicle controller via a can (controller Area network) bus. Also illustratively, during vehicle startup, a voltage value of the battery may be detected by a battery voltage sensor mounted on the vehicle, and the detected voltage value may be transmitted to the vehicle control unit through the CAN bus. Further illustratively, during vehicle start-up, the state of charge and the voltage value of the battery may be detected by a battery level sensor mounted on the vehicle, and the detected state of charge and the detected voltage value of the battery may be transmitted to the vehicle controller through the CAN bus.
In S102, a threshold value of the battery is determined based on the battery history state information.
The threshold value of the battery can be used for representing the threshold value of the health state of the battery. For example, the battery is in a healthy state when the voltage value, and/or the state of charge of the battery is greater than or equal to the threshold value, and the battery is in an unhealthy state when the voltage value, and/or the state of charge of the battery is less than the threshold value.
In S103, current state information of the storage battery during the current starting process of the vehicle is acquired.
The current state information of the storage battery is used for representing the state information of the storage battery in the current starting process of the vehicle, and the current state information of the storage battery can comprise the current voltage value and/or the current state of charge of the storage battery. For example, the current voltage value of the storage battery, and/or the current state of charge may be a voltage value or a state of charge at the moment of starting the vehicle, or may be a voltage value or a state of charge at any time during starting of the vehicle. And is not particularly limited herein.
In S104, it is determined whether the battery is in a healthy state based on the critical value of the battery and the current state information of the battery.
By adopting the technical scheme, when the vehicle control unit detects a vehicle starting signal, the vehicle control unit acquires the historical state information of the storage battery in the historical starting process of the vehicle, determines the critical value of the storage battery according to the historical state information of the storage battery, then acquires the current state information of the storage battery in the current starting process of the vehicle, and further determines whether the storage battery is in a healthy state or not according to the critical value of the storage battery and the current state information of the storage battery. Therefore, the vehicle control unit can determine whether the storage battery is in a healthy state or not according to the historical state information and the current state information of the storage battery, the storage battery does not need to be detached from the vehicle and professional equipment is used for detecting the state of the storage battery, therefore, the convenience of detecting the state of the storage battery is improved, and whether the storage battery is in a healthy state or not can be detected in the starting process of the vehicle, so that a vehicle owner can timely learn the state of the storage battery, and timely measures are taken when the storage battery is in an unhealthy state, and the normal starting of the vehicle is further ensured.
In order to make the vehicle-mounted battery state detection method provided by the present disclosure better understood by those skilled in the art, the method is described below in a complete embodiment.
FIG. 2 is a flow chart illustrating a method for determining a threshold value of a battery according to an exemplary embodiment. As shown in fig. 2, step 101 in fig. 1 may specifically include step 1011.
In step 1101, historical state information of the storage battery during the previous N times of historical starting processes closest to the current starting time is acquired to obtain N historical voltage values and/or N historical states of charge, where N is a positive integer greater than 1.
The inventor considers that the detected voltage value or the charge state of the storage battery possibly does not accord with the actual state of the storage battery due to the influence of floating electricity in the storage battery at the moment of starting the vehicle, so that the reliability of the detected voltage value or the charge state of the storage battery is reduced, and considers that the voltage value and the charge state of the storage battery can both reduce to a trough due to the energy supply of the storage battery during the starting process of the vehicle, and the voltage value and the charge state of the storage battery can recover to normal levels after the starting is completed, so in the disclosure, the historical voltage value and the historical charge state stored in the storage unit in the vehicle can be respectively the minimum voltage value and the minimum charge state during each starting process in the historical starting process of the vehicle, and the current voltage value and the current charge state of the storage battery obtained during the starting process of the vehicle can be respectively the minimum voltage value and the minimum charge state during the starting process of the vehicle, Minimum state of charge.
In addition, the inventor also considers that the electric energy required for starting the vehicle is different under different environments, namely the minimum voltage value and the minimum state of charge are different during the starting process of the vehicle under different environments. For example, in summer, less electrical energy is required to start the vehicle due to a higher outside temperature. For example, if the voltage value of the battery is 13V in a normal state, the lowest voltage value of the battery may be 10V during the start of the vehicle. In winter, the vehicle needs more electric energy for starting because the outside temperature is lower. For example, if the voltage value of the battery is 13V in a normal state, the lowest voltage value of the battery may be 8V during the start of the vehicle. In both of the above examples, the state of the battery is a healthy state. In addition, the minimum value of the state of charge during vehicle start-up is also environmental dependent and is not illustrated here. Therefore, if a fixed voltage value and/or a fixed state of charge is used as a critical value for determining whether the battery is in a healthy state, the method cannot be applied to different environments, and is prone to cause misjudgment of the state of the battery.
Therefore, in the present disclosure, when determining whether the storage battery is in a healthy state, historical state information of the storage battery during the previous N times of historical starting processes closest to the current starting time is obtained to obtain N historical voltage values and/or N historical states of charge, and then a critical value of the storage battery is determined according to the obtained historical state information of the storage battery. Wherein N is a positive integer greater than 1, e.g., N is 10, 15, etc.
Specifically, as shown in fig. 2, step 102 in fig. 1 may include the following steps.
In step 1021, calculating a voltage average of the N historical voltage values, and multiplying the voltage average by a first preset coefficient to obtain a voltage threshold; and/or the presence of a gas in the gas,
in step 1022, the state of charge average of the N historical states of charge is calculated, and the state of charge average is multiplied by a second preset coefficient to obtain a state of charge threshold.
The first preset coefficient and the second preset coefficient can be stored in a storage unit of the vehicle control unit in advance, the value range of the first preset coefficient is (0, 1), and the value range of the second preset coefficient is (0, 1). Illustratively, the first predetermined factor is 0.9, the second predetermined factor is 0.89, and so on. It should be noted that the first preset coefficient and the second preset coefficient may be the same or different, and are not limited herein.
In addition, in order to improve the accuracy of the determined threshold value, in the present disclosure, the acquired N historical voltage values, the voltage average value of the N historical states of charge, and the state of charge average value are calculated, respectively, considering that the lowest voltage value or the lowest state of charge of the battery is different during the starting process even if the vehicle is started under the same environment. In addition, as will be appreciated by those skilled in the art, since a certain detection error exists when detecting the voltage value and the state of charge, and the battery may be in a healthy state when the minimum voltage is less than the voltage average value or the minimum state of charge is less than the state of charge average value, in the present disclosure, after calculating the voltage average value and the state of charge average value, the voltage average value is multiplied by a first preset coefficient to obtain a voltage threshold value, and/or the average value of the state of charge is multiplied by a second preset coefficient to obtain a state of charge threshold value, so that the determination of whether the battery is in a healthy state is more accurate and reliable.
In the present disclosure, after the critical value of the battery is determined, whether the battery is in a healthy state may be determined according to the critical value of the battery and the current state information of the battery.
Optionally, determining whether the battery is in a healthy state according to the battery critical value and the current state information of the battery comprises:
when the critical value of the storage battery and the current state information of the storage battery meet at least one of a first preset condition and a second preset condition, determining that the storage battery is in an unhealthy state; the first preset condition is that the current voltage value of the storage battery is smaller than a voltage critical value, and the second preset condition is that the current state of charge of the storage battery is smaller than a state of charge critical value.
In one embodiment, whether the battery is in a healthy state may be determined based on a voltage threshold of the battery and a current voltage value of the battery. Specifically, when the current voltage value of the battery is less than the voltage critical value of the battery, it is determined that the battery is in an unhealthy state. And when the current voltage value of the storage battery is larger than or equal to the voltage critical value of the storage battery, determining that the storage battery is in a healthy state.
In another embodiment, it may be determined whether the battery is in a healthy state based on a state of charge threshold of the battery and a current state of charge of the battery. Specifically, when the current state of charge of the battery is less than the state of charge threshold, the battery is determined to be in an unhealthy state. And when the current state of charge of the storage battery is greater than or equal to the state of charge critical value, determining that the storage battery is in a healthy state.
In yet another embodiment, it may be determined whether the battery is in a healthy state based on the state-of-charge threshold of the battery and the current state-of-charge of the battery, and based on the voltage threshold of the battery and the current voltage value of the battery, and it may be determined that the battery is in an unhealthy state when the current state-of-charge of the battery is less than the state-of-charge threshold and the current voltage value of the battery is less than the voltage threshold of the battery.
By adopting the scheme, the influence of floating electricity in the storage battery on the test result can be eliminated, and the critical value of the storage battery is determined according to the historical state information of the storage battery closest to the starting time, so that the determined critical value can better accord with the environment of the vehicle during the starting, the accuracy of the determined critical value is improved, and whether the storage battery is in a healthy state or not can be accurately and reliably determined based on the more accurate critical value.
Fig. 3 is a flowchart illustrating an on-vehicle battery state detection method according to another exemplary embodiment. As shown in fig. 3, the method includes S105 in addition to the above-described S101-S104.
In S105, if it is determined that the battery is in an unhealthy state, alarm information is output.
The manner of outputting the alarm information is various, for example, the alarm information may include at least one of the following: pop-up windows, voice alarms, alarm icons, and the like.
For example, the alarm information includes a pop-up window, and when it is determined that the storage battery is in an unhealthy state, the pop-up window may be displayed on a display screen of the vehicle-mounted infotainment system, and the pop-up window includes warning information that the storage battery is in an unhealthy state, so as to remind a user that the storage battery is in an unhealthy state, which may affect the next normal start of the vehicle.
In another example, the alarm information includes a voice alarm, and when it is determined that the storage battery is in an unhealthy state, the storage battery is reported to be in the unhealthy state in a voice broadcast mode.
In another example, the alarm information includes a voice alarm and an alarm icon, and when the storage battery is determined to be in an unhealthy state, the storage battery is reminded of the unhealthy state by means of the voice alarm and the alarm icon, so that the user can be reminded of paying attention more obviously. It should be noted that the above alarm information is only an example, and other alarm information is also applicable to the present disclosure.
Therefore, the user can timely learn the state of the storage battery and timely take measures when the storage battery is in an unhealthy state, so that the problem that the vehicle cannot be normally started due to serious aging of the storage battery is avoided.
Based on the same invention concept, the invention also provides a vehicle-mounted storage battery state detection device. Fig. 4 is a block diagram illustrating an in-vehicle battery state detection apparatus according to an exemplary embodiment. The apparatus 400 may include:
