Embodiment Construction

[0027] The embodiment of the present invention at least solves the technical problems of low reliability and high cost in the charging protection of the vehicle in the related art by providing a vehicle charging protection method, device, electronic equipment and storage medium.

[0028] The technical solutions provided by the embodiments of the present invention are to solve the above-mentioned technical problems, and the general idea is as follows:

[0029] During the charging process of the vehicle, the resistance data of the thermistor installed at the charging socket of the vehicle is obtained, and based on the resistance data, the temperature data represented by the thermistor can be determined by using the corresponding relationship between the resistance of the thermistor and the temperature. Since the resistance of the RC circuit connected in series with the thermistor can be obtained in advance, the target charging gear of the charging socket can be determined from th...

Abstract

The embodiment of the invention provides a vehicle charging protection method and device, electronic equipment and a storage medium. In the charging process of the vehicle, resistance data of a thermistor arranged at the position of a charging socket of the vehicle are obtained, then a target charging gear of the charging socket is determined from a plurality of preset charging gears based on the resistance data and resistance of an RC circuit connected with the thermistor in series, and finally the charging process of the vehicle is controlled based on the target charging gear. Based on the resistance data, temperature data represented by the thermistor is determined by using the corresponding relation between the resistance and the temperature of the thermistor, and the charging gear is set based on the temperature data. As an additional temperature acquisition circuit is not needed, the cost is reduced, the technical problem of low reliability of a traditional temperature acquisition circuit is solved, and the reliability in the vehicle charging process is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle charging protection method, device, electronic equipment and storage medium. Background technique [0002] The vehicle socket is a component used for charging electric vehicles. In actual use, due to the large current of the high-voltage circuit, the temperature is prone to rise after long-term use, and in severe cases, it may cause a short circuit or even a fire. [0003] In order to avoid the above problems, a temperature sampling loop will be connected to the vehicle socket, and an additional temperature control strategy will be designed to protect the temperature of the vehicle socket. However, the reliability of the connection of the sampling loop, the consistency of the arrangement of the temperature sensor, and the rationality of the design of the temperature protection strategy all affect whether the temperature sampling loop can play a protective role. Co...
