referring to fig. 2, fig. 2 is a schematic flow chart of a method for predicting the life of an automobile battery according to an embodiment of the present disclosure. As shown in fig. 2, the method for predicting the life of the automobile storage battery comprises the following steps:
step 201: the storage battery sensor collects battery characteristic data of the storage battery and sends the battery characteristic data to the gateway.
The storage battery sensor monitors the working state of the storage battery in real time, collects battery characteristic data of the storage battery at the same time, and transmits the collected battery characteristic data to the gateway through a serial interconnection Network (LIN) after collecting the battery characteristic data of the storage battery.
In general, battery characteristic data of a secondary battery includes battery startability (Bat _ SOF), internal resistance (Bat _ Ri), active material loss (Bat _ Lam), degree of vulcanization (Bat _ Sul), degree of plate corrosion (Bat _ Cor), temperature (Bat _ Temp), charge-discharge rate (Bat _ Crnt), and the like.
Step 202: the vehicle information acquisition module acquires vehicle state data and sends the vehicle state data to the gateway, and the vehicle state data can reflect the user's habit of using the vehicle and the vehicle driving condition.
The vehicle information acquisition module acquires vehicle state data generated in the current running process of a vehicle, the vehicle state data CAN reflect the vehicle using habit of a user on one hand and the current running working condition of the vehicle on the other hand, and after the vehicle state data are acquired by the vehicle information acquisition module, the acquired vehicle state data are sent to a gateway through LIN or a Controller Area Network (CAN).
It should be noted that, in an automobile powered by a gasoline engine and a diesel engine, the vehicle information acquisition module generally includes an EMS, a generator, and a load; correspondingly, the vehicle state data comprises vehicle running state information, whole vehicle charging voltage, load rate and load state signals; the vehicle state information is collected by an EMS (energy management system), the vehicle state information is sent to a gateway by the EMS through a CAN (controller area network), the charging voltage and the load rate of the whole vehicle are collected by a generator, the charging voltage and the load rate of the whole vehicle are sent to the gateway by the generator through an LIN, a load state signal is collected by load feedback, the load state signal is sent to the gateway by a load through the CAN or the LIN, and the load state signal mainly refers to the on-off state of some electric appliances on the vehicle.
It should be noted that, in an electric vehicle or a hybrid vehicle, the vehicle information acquisition module generally includes a VCU, an HVDCDC and a load; correspondingly, the vehicle state data comprises vehicle running state information, whole vehicle charging voltage, load rate and load state signals; the vehicle state information is collected by a VCU, the vehicle state information is sent to a gateway by the VCU through a CAN, the charging voltage and the load rate of the whole vehicle are collected by HVDCDC, the charging voltage and the load rate of the whole vehicle are sent to the gateway by the HVDCDC through LIN, a load state signal is collected by a load, the load state signal is sent to the gateway by the load through the CAN, and the load state signal mainly refers to the on-off state of some electric appliances on the vehicle.
Step 203: and the gateway determines the initial value of the SOH of the storage battery according to the battery characteristic data.
And after receiving the battery characteristic data sent by the storage battery sensor, the gateway determines the initial value of the SOH of the storage battery according to the received battery characteristic data.
It should be noted that the gateway may determine the initial value of SOH by querying the parameter table of the storage battery according to the battery characteristic data; the storage battery parameter table comprises battery characteristic data recorded when the storage battery with the same model as the storage battery is subjected to aging test.
That is, the gateway needs to obtain a storage battery parameter table of the same model in advance, the storage battery parameter table records the corresponding relationship between the SOH value of each stage and the battery characteristic parameter of the storage battery in the aging test process of the storage battery of the model, and the gateway can search the SOH value corresponding to the battery characteristic parameter in the storage battery parameter table according to the battery characteristic parameter received by the gateway, and further, the SOH value is used as the SOH initial value.
Step 204: the gateway sends the SOH initial value and the vehicle state data to the server through the telematics processor.
After determining the SOH initial value and obtaining the vehicle state data, the gateway performs operation processing on the SOH initial value and the vehicle state data to obtain packed data of the SOH initial value and the vehicle state data, and then sends the packed data to the server through the vehicle-mounted T-box through the network.
Step 205: the server calculates an SOH correction value according to the SOH initial value and the vehicle state data; and judging whether the SOH correction value is smaller than the calibration correction value, and if so, sending a storage battery replacement reminding message to the terminal equipment.
And after receiving the packaged data sent by the vehicle-mounted T-box, the server processes the packaged data to obtain an SOH initial value and vehicle state data of the storage battery, and further calculates an SOH correction value according to the SOH initial value and the vehicle state data. And then, the server judges whether the SOH correction value is smaller than the calibration correction value SOH _ Critical, if so, the storage battery is irreversibly aged and needs to be replaced, and correspondingly, the server sends a storage battery replacement reminding message to the terminal equipment.
It should be noted that the terminal device may specifically include an intelligent terminal, an internet large screen and a vehicle instrument, that is, the server may send the battery replacement reminding message to a client (APP), an internet large screen (FICM) and a vehicle instrument running on the intelligent terminal, so as to notify the user that the battery may be replaced.
When the server calculates the SOH correction value according to the SOH initial value and the vehicle state data, a weighting algorithm may be first adopted to calculate the SOH correction coefficient according to the vehicle state data, and then the SOH correction coefficient is used to correct the SOH initial value to obtain the SOH correction value.
When the server calculates the SOH correction coefficient, the SOH correction coefficient may be calculated by using a formula shown in formula (1):
f(x)＝x1·λ1+x2·λ2+x3·λ3+x4·λ4+.....(1)
where f (x) is an SOH correction coefficient, x1, x2, x3, x4, and the like are all various vehicle state data, specifically, the vehicle state data may be mileage, vehicle speed, vehicle operating time, ambient temperature, and the like, and λ 1, λ 2, λ 3, and λ 4 are weights corresponding to different vehicle state data, respectively. It should be understood that the vehicle state data having a greater effect on the service life of the battery is weighted more heavily, whereas the vehicle state data having a lesser effect on the service life of the battery is weighted less heavily.
When the server corrects the SOH initial value by using the SOH correction coefficient, the calculation may be performed by using a formula shown in formula (2):
SOH_Dsp＝SOH_GW*f(x) (2)
wherein SOH _ Dsp is an SOH correction value, SOH _ GW is an SOH initial value, and f (x) is an SOH correction coefficient.
It should be noted that, the server may also send a vehicle usage habit guidance prompt message to the terminal device according to the vehicle state data, for example, send a prompt to avoid parking for a long time and turning on the electrical equipment, and prompt the battery to be aged to select a large-current charging mode to activate the battery, so as to prompt the user to adopt a correct vehicle usage habit, so that the user may use the vehicle based on the correct vehicle usage habit, thereby ensuring that the service life of the storage battery is prolonged as much as possible.
In addition, the server can also preset the prompting times of the storage battery replacement prompting message, and correspondingly, after the server sends the storage battery replacement prompting message to the terminal equipment, the terminal equipment reminds the storage battery replacement according to the prompting times.
In general, the server sends a battery replacement reminding message to the terminal device after judging that the vehicle is started. Specifically, the server may obtain a Power Mode of the entire vehicle, and send a battery replacement reminding message to the terminal device when the Power Mode is run.

the vehicle information acquisition module is used for acquiring vehicle state data and sending the vehicle state data to the gateway, and the vehicle state data can reflect the vehicle using habits of users and the vehicle running conditions;
the gateway is used for determining an initial value of the capacity SOH of the storage battery according to the battery characteristic data, and sending the initial value of the SOH and the vehicle state data to the server through the remote information processor;
the server is used for calculating an SOH correction value according to the SOH initial value and the vehicle state data; judging whether the SOH correction value is smaller than a calibration correction value or not, and if so, sending a storage battery replacement reminding message to the terminal equipment;
the server calculates an SOH correction value based on the SOH initial value and the vehicle state data, including:
the server calculates an SOH correction coefficient according to the vehicle state data by adopting a weighting algorithm;
when the server calculates the SOH correction coefficient, the following formula is adopted for calculation:
f(x)＝x1·λ1+x2·λ2+x3·λ3+x4·λ4+……
(x) is an SOH correction coefficient, x1, x2, x3, x4 and the like are all various vehicle state data, specifically, the vehicle state data may be mileage, vehicle speed, vehicle running time, ambient temperature and the like, λ 1, λ 2, λ 3 and λ 4 are weights corresponding to different vehicle state data, and the weight corresponding to the vehicle state data having a greater influence on the service life of the battery is greater, and the weight corresponding to the vehicle state data having a smaller influence on the service life of the battery is smaller;
correcting the initial SOH value by using the SOH correction coefficient to obtain the SOH correction value, wherein the step of correcting the initial SOH value by using the SOH correction coefficient comprises the following steps:
when the server corrects the SOH initial value by using the SOH correction coefficient, the following formula is adopted for calculation:
SOH_Dsp＝SOH_GW*f(x)
SOH _ Dsp is an SOH correction value, SOH _ GW is an SOH initial value, and f (x) is an SOH correction coefficient.
