Charging control method and system of electric vehicle, and electric vehicle

Abstract

The invention provides a charging control method and system of an electric vehicle, and an electric vehicle. The charging control method comprises the following steps: detecting the voltage of a battery; judging whether the voltage of the battery is less than the first preset voltage; if so, sending a battery low voltage reminder message and an automatic charging request to the user terminal; andafter receiving the instruction allowing automatic charging, fed back by the user terminal, controlling the charging device to charge the battery. The charging control method can send reminding information and charging request to the user when the voltage of the vehicle battery is too low, thereby facilitating the timely supplement of the battery power, avoiding the power deficit phenomenon causedby the long-term parking of the vehicle, greatly facilitating the user, lowering the required cost, and improving the user experience.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a charging control method and system for an electric vehicle and the electric vehicle. Background technique [0002] In recent years, people have paid more and more attention to energy saving and environmental protection, which has promoted the rapid development of new energy vehicles, resulting in a substantial increase in electronic components on new energy vehicles, resulting in an increase in low-voltage power consumption and shortening the self-discharging time of batteries. Problems are becoming increasingly apparent and affecting user experience. [0003] If the electric vehicle is unmanned for a long time, the battery will discharge by itself or be artificially discharged. If the battery is in a state of low power at this time, there will be problems that the power supply cannot be started to supply power to the electrical equipment or the vehicle cannot be star...

AI Technical Summary

Problems solved by technology

[0002] In recent years, people have paid more and more attention to energy saving and environmental protection, which has promoted the rapid development of new energy vehicles, resulting in a substantial increase in electronic components on new energy vehicles, resulting in an increase in low-voltage power consumption and shortening the self-discharging time of batteries. The problem is becoming more and more obvious and affecting the user experience

[0003] If the electric vehicle is unmanned for a long time, the battery will discharge by itself or be artificially discharged. If the battery is in a state of power loss at this time, there will be problems that the power supply cannot be started to supply power to the electrical equipment or the vehicle cannot be started.

[0004] In view of the above problems, the current related technologies can only meet the fixed standing time, need to choose a large capacity low-voltage battery, and require the user to actively start the vehicle by himself, and charge the low-voltage battery through the power battery in the vehicle, which cannot be used from the perspective of the user and the whole. From the perspective of vehicle lightweight, more humanized design will not only increase the cost and weight, but also occupy the installation space of the vehicle, and cause inconvenience for customers after power loss
