Embodiment 1

[0048] At present, the traditional mode of power battery fault diagnosis is data collection and judgment during the use of the power battery in the vehicle. It is impossible to predict whether the power battery is faulty in advance, which directly increases the maintenance cost of the vehicle and also affects the customer experience of the car owner. Extremely poor impact, if the online inspection speed is not fast enough, there will be dangerous accidents such as fire and explosion of the power battery. As a new energy vehicle company, it is impossible to predict the quality problems of the power battery in a timely manner, which may cause high service costs and vehicle recalls for the car company, directly affecting the brand and reputation of the car company. Through the monitoring and analysis of power battery data by big data method, the qualified power battery, abnormal power battery and high-risk power battery can be quickly screened to achieve the effect of real-time al...

Embodiment 2

[0084] According to the first embodiment, this embodiment provides a method for judging potential hazards of a power battery by voltage, which is applicable to the situation where the power battery is installed in a vehicle and the power battery is charged at a charging station. See image 3 , image 3 A flow chart of a method for judging hidden dangers of a power battery for voltage. Figure 5 Among them, the steps for judging the hidden dangers of the power battery by voltage include:

[0085] S301. Collect a set of voltage data.

[0086] In order to ensure that the collected data is the data of the same battery pack in the same vehicle, the vehicle power battery monitoring platform will also collect the analysis dimension data of the battery while collecting the voltage data, such as: vehicle identification code and battery identification code ; Only when the identification number of the vehicle or the identification number of the battery does not change within any perio...

Embodiment 3

[0124] This embodiment provides a vehicle power battery monitoring device, please refer to Figure 4 , Figure 4 A schematic structural diagram of a vehicle power battery monitoring device provided by an embodiment of the present invention. The vehicle power battery monitoring device includes: an acquisition module 401 , a calculation module 402 and a judgment module 403 .

[0125] The collection module 401 is used to collect the data to be analyzed of the power battery of the vehicle, the data to be analyzed includes the performance data of the power battery collected from the vehicle during use, and the data collected from the charging station during the charging process of the power battery performance data in . Specifically, the performance data includes the current, voltage and operating temperature of the power battery.

[0126] Further, the collection module 401 is also used to collect the analysis dimension data of the power battery, as well as the current remaining...

Abstract

The embodiment of the invention provides a vehicle power battery monitoring method, device and platform. The vehicle power battery monitoring method comprises the steps of collecting to-be-analyzed data of a power battery of a vehicle, wherein the to-be-analyzed data comprises performance data collected by the power battery of the vehicle in the using process and performance data collected by thepower battery when the power battery is charged in a charging station; inputting the acquired to-be-analyzed data into a preset constant-force battery monitoring model to obtain an output result; andjudging whether the power battery has potential safety hazards according to an output result. According to the embodiment of the invention, the vehicle power battery monitoring platform collects the to-be-analyzed data of the vehicle power battery through the Internet of Vehicles technology, analyzes the information of the to-be-analyzed data through a big data analysis means, and solves a problemthat the potential safety hazard of the current vehicle power battery cannot be found timely and accurately.

Description

technical field [0001] The present invention relates to the field of power batteries, and more particularly, to a vehicle power battery monitoring method, device and platform. Background technique [0002] With the rapid development of the economy and the promotion of the green economy, new energy vehicles have become the main direction of the development of the automotive industry. With the development of new energy vehicles, the Internet of Vehicles technology based on big data has also been developed. [0003] At present, in more and more new energy vehicles, the power battery is a very important component of the new energy vehicle; however, with the increase in the service time of the power battery and the increase in the number of uses, the failure of the power battery becomes more and more common. The more frequent, the power battery failure will affect travel at least, and cause serious safety accidents at worst. Therefore, the diagnosis of battery failure is very nec...
