[0001] The present application relates to the technical field of Internet of Things, and particularly relates to a vehicle internet of things based automobile equipment remote control system and method. BACKGROUND

[0002] In a new energy vehicle system mainly using electric energy, a storage battery plays an important role, and with the increase of storage battery capacity and energy density, a degraded storage battery cannot meet daily use and may have a security risk, so monitoring of a storage battery health state is increasingly important.

[0003] When a new energy vehicle is not used for a long time, due to battery aging and environmental influence during storage, a battery management system of the new energy vehicle locally has an error in battery power statistics, which easily causes a sharp decrease of battery power during driving, and causes inconvenience to drivers and passengers.

[0007] Step S200: taking a new energy vehicle as a target vehicle, obtaining a use record of a battery of the target vehicle when the target vehicle receives a vehicle power-off instruction, uploading the use record to the data management platform, and evaluating the battery through the data management platform;

[0008] Step S300: when the battery state evaluation result is qualified, collecting battery state data of the target vehicle, backing up the battery state data to the data management platform, and powering off the target vehicle after the backup of the battery state data is completed;

[0009] Step S400: when the target vehicle is powered on again, collecting current battery state data of the target vehicle and sending the current battery state data to the data management platform, comparing the current battery state data with the backed up battery state data, and judging whether a start state of the target vehicle is abnormal;

[0010] Step S500: feeding back an evaluation result of the start state of the target vehicle to a receiving terminal, and giving an alarm prompt when the battery state is unqualified.

[0011] Further, the step S100 comprises:

[0012] Step S101: collecting the driving record of the new energy vehicle, classifying the driving record according to the road conditions of the new energy vehicle driving, collecting the function relationship between the remaining battery capacity and the vehicle driving time under different road conditions, and obtaining the battery capacity change function of various road conditions;

[0013] Step S102: obtaining the voltage drop value of the battery when the new energy vehicle is initially started, recording the voltage drop value as a voltage drop reference value, obtaining the initial internal resistance of the battery of the new energy vehicle, and combining the initial internal resistance and the voltage drop reference value to form a numerical reference group, and the correspondence between the new energy vehicle and the numerical reference group is stored in the server of the data management platform.

[0014] Further, the step S200 comprises:

[0015] Step 201: taking the moment when the target vehicle receives the vehicle closing instruction as the target termination moment, taking the power-on moment closest to the target termination moment in the list as the target starting moment, and taking the time period from the target starting moment to the target termination moment as the target time period;

[0016] Wherein, power-on refers to the process of the new energy vehicle from the stop state to the start state, and in the power-on process, the battery management system connects the output circuit of the battery to provide power supply to the motor controller and other electrical equipment;

[0017] Step 202: obtaining the driving record of the target vehicle in the target time period, taking the road condition information in the driving record as the target road condition, and matching the battery capacity change function corresponding to the target road condition in the data management platform;

[0018] Step 203: obtaining the remaining capacity of the battery of the target vehicle at the target starting moment, taking the remaining capacity as the initial capacity, obtaining the time length of the driving record, obtaining the battery capacity remaining value according to the battery capacity change function corresponding to the target road condition, recording the battery capacity remaining value as the reference capacity, and recording the difference between the initial capacity and the reference capacity as the reference power consumption E1;

[0019] Step 204: obtaining the remaining capacity of the battery of the target vehicle at the target termination moment, taking the remaining capacity as the actual remaining capacity, and recording the difference between the initial capacity and the actual remaining capacity as the actual power consumption E2;

[0022] By analyzing the change of the internal resistance of the battery, the increase of the internal resistance generally indicates the aging degree of the battery, and the internal resistance of the battery will increase with the use of the battery;

[0023] Step 207: Divide the battery of the target vehicle into several unit areas, obtain the temperature values of all unit areas at the target termination time, calculate the variance of the temperature values, denoted as Var;

[0029] The state of charge, namely SOC, is the ratio of the remaining capacity to the rated capacity under a certain discharge rate;

[0030] Step 303: When H>Q1, the battery state evaluation result is unqualified, and the battery state feedback is abnormal.

[0031] Further, step S400 comprises:

[0032] Step S401: set a time threshold T0, obtain the time of re-powering, when the time interval between the time and the target termination time is greater than T0, and there is no charging record of the target vehicle in the time interval, record the power-on process of the target vehicle as the target start;

[0033] Step S402: after the target start is completed, obtain the battery state data of the target battery, record the battery state data as the current state data, calculate the difference between the backup state data and the current state data, and record the difference as the difference evaluation value D;

[0034] Step S403: obtain the voltage drop value v1 of the target start of the target vehicle and the voltage drop reference value v0 of the target vehicle, calculate the difference evaluation coefficient a, a= (v1-v0) / v0;

[0035] When the battery is powered, the internal chemical reaction generates electric energy, and when the battery is externally connected to the load, it will cause a certain internal resistance drop in the battery. With the aging of the battery, the internal resistance increases, and the greater the internal resistance, the greater the voltage drop generated by the battery during discharge, thereby causing the drop of the battery terminal voltage;

[0036] Step S404: calculate the start state evaluation value F, F= a x D, when F is greater than the evaluation threshold Q2, it is judged that the start state of the target vehicle is abnormal.

[0037] Further, step S500 includes:

[0038] Step S501: when the start state of the target vehicle is abnormal, the data management platform feeds back the evaluation result to the vehicle-mounted terminal of the vehicle, and displays the information that the start state is abnormal through the instrument panel or central control screen of the vehicle;
