After the state of the storage battery, the state of the vehicle power supply, the state of the vehicle engine, the state of the vehicle power generation and the driving range of the vehicle are detected, a signal including the states can be sent to a GateWay (GateWay, GW), the GW transmits the signal of the states to a vehicle-mounted terminal (telematics BOX, T-BOX), and the T-BOX transmits the signal of the states to a data platform.
And step S12, determining the reason of the insufficient power of the storage battery according to one or more of the state of the storage battery, the state of the whole vehicle power supply of the vehicle, the state of the engine of the vehicle, the state of the power generation of the vehicle and the driving range of the vehicle based on the state of the vehicle.
For example, for each vehicle, the data platform may store indicia representing the status of the vehicle, such as the vehicle being in inventory during the period of inventory, and sold after it has been sold. After receiving the signal of the state, the data platform can determine the reason of the power shortage of the storage battery according to the signal. The method of determining the cause of a battery power shortage differs when the vehicle is in different states. Specifically, the following 7 types of factors are classified into the following categories according to the reasons of power shortage, which will be described in detail below. The following data are examples and do not limit the present invention.
First, a vehicle may be self-tested every 7 days when the status of the vehicle is in inventory, for which,
1. when the storage battery State is detected to be a storage battery State of Charge (SOC) value less than or equal to a first Charge threshold (for example, 70%) in a preset detection time (for example, 5 times), determining that the reason of the storage battery power shortage is improper maintenance-accumulation abnormity;
2. when the state of the storage battery is detected to be that the state of charge of the storage battery is smaller than or equal to a first charge threshold (for example, 70%), and the state of charge of the storage battery is not larger than a second charge threshold (for example, 85%) within a first preset time (for example, 48 hours), determining that the reason of the power shortage of the storage battery is improper maintenance-abnormal charging;
3. when the signal of the state of charge value of the storage battery is not detected within a second preset time (for example, 30 days), determining that the reason of the power shortage of the storage battery is improper maintenance-overtime maintenance;
4. upon detecting that the battery state is a battery state of health value (SOH) of equal to or less than a first health threshold (e.g., 80%), determining that the cause of the battery power loss is a maintenance error, battery aging.

in addition, when the signal that the state of charge of the storage battery is not detected for more than 15 days or the engine state of the vehicle is in a flameout state (the situation that the EngState signal is not always equal to 2), the signal that the state of charge of the storage battery or the engine state of the vehicle is detected to be changed, and the difference between the state of charge of the storage battery and the last detected state of charge of the storage battery is detected to be more than or equal to 20%, the vehicle is marked as long-time storage-charge reduction.
Sixth, during the period when the vehicle is in a state of being sold, for this,
1. when the fact that the driving distance of the vehicle is smaller than the first preset distance (for example, 500 kilometers) within an eighth preset time (for example, three months) and the single driving time is smaller than a ninth preset time (for example, 1 hour) is detected, the reason of the power shortage of the storage battery is determined to be short-distance failure.
Seventh, during the period when the vehicle is in a state of being sold, for this,
1. when the vehicle power state is detected to be ON (for example, the SysPowerMod signal is 2), the vehicle engine state is detected to be the starting state (for example, the EngState signal is 2), and the vehicle power generation state is the power generation fault (for example, the generatorwarnlampsts signal is 1), when the battery states are all battery state values smaller than a fourth charge threshold value (for example, 50%), the cause of the battery power shortage is determined to be the power supply system fault.
Wherein the data platform may store and curve all SOC and SOH data during the vehicle from inventory period to show period, from show period to sold period, and throughout sold period, as shown in fig. 2.
