Problems solved by technology
[0003] When the service life of the battery is near the end, it will affect the normal operation of the vehicle, and in severe cases, the vehicle may suddenly fail to start
In the prior art, the user can usually only indirectly know the current service life information of the battery according to certain phenomena during the operation of the vehicle, and then judge whether the battery needs to be replaced. For example, during the operation of the vehicle, if If the vehicle starts weakly, the light brightness is insufficient, and the sound of the horn is weakened, the user can judge accordingly that the current service life of the battery is nearing the end and the battery needs to be replaced
[0004] However, the battery life information determined by observing the phenomena that occur during the operation of the vehicle is generally not accurate and reliable. The user cannot accurately determine the timing of replacing the battery only based on the battery life information determined in this way. If the battery is not replaced in time, During the operation of the whole vehicle, the vehicle will not be able to guarantee a good working condition, which will affect the user's car experience

This application discloses a method for predicting the life of an automobile battery that is applied to a battery life prediction system. The battery life prediction system specifically includes a battery, a battery sensor, a vehicle information collection module, a gateway, a telematics processor, and a server; The battery characteristic data, send the battery characteristic data of the battery to the gateway; the vehicle information collection module collects the vehicle status data, and sends the vehicle status data to the gateway; the gateway determines the initial value of SOH according to the battery characteristic data, and sends the initial value of SOH to the and vehicle status data to the server; the server calculates the SOH correction value based on the SOH initial value and vehicle status data, and when judging whether the SOH correction value is less than the calibration correction value, sends a battery replacement reminder message to the terminal device to ensure timely and accurate reminders The user needs to replace the battery.
Description
Technical field [0001] The present application relates to the field of automotive electronics, and in particular, there is an automotive battery life prediction method and apparatus. Background technique [0002] The main role of the battery in the vehicle is to provide electrical energy to the starter when the vehicle is started to drive the engine or inhalation of high pressure relays, when the vehicle load demand exceeds the generator or high voltage DC DC converter (HIGH VOLTAGE DC- The output of TO-DC Converter, HVDCDC is not started, and the battery will participate in power supply. All in all, the battery can not operate for the operation of the vehicle, it can ensure the safe and stable operation of the vehicle system. [0003] When the battery life will be in the service life, it will affect the normal operation of the vehicle, and the vehicle that can suddenly be suddenly unable to start when severe. In the prior art, users typically only use certain phenomena, indirect...
