Charging control method and system for electric vehicle and electric vehicle

Abstract

The present invention proposes a charging control method and system for an electric vehicle, and the electric vehicle. The method includes the following steps: detecting the voltage of the storage battery; judging whether the voltage of the storage battery is lower than the first preset voltage; if so, sending the battery low voltage to the user terminal Voltage reminder information and automatic charging request; after receiving the automatic charging instruction fed back by the user terminal, control the charging device to charge the battery. The present invention can send a reminder message and a charging request to the user when the voltage of the vehicle battery is too low, thereby facilitating timely replenishment of battery power, avoiding power loss caused by long-term parking of the vehicle, greatly facilitating the user, and requiring low cost and improving user experience.

Description

Technical field[0001]The present invention relates to the field of electric vehicles, and more particularly to a charging control method, system, and electric vehicle for electric vehicles.Background technique[0002]In recent years, people have increasing the attention of energy conservation and environmental protection, which has promoted the rapid development of new energy vehicles, so that the electronic components on new energy vehicles have increased significantly, resulting in an increase in low-voltage electricity, and the battery is shortened. The problem is increasing and affects the user experience.[0003]Electric cars have no driving for a long time, and the battery will discharge itself or will be discharged. If the battery is in a loss, there is a problem that the power supply is powered or unable to activate the vehicle.[0004]For the above problems, the current related technologies can only meet the fixed time, and need to select a larger capacity low-voltage battery, an...

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
