Abstract

The embodiment of the invention provides an electric vehicle power control method and device and a processing circuit. The method comprises the following steps: respectively receiving a voltage signal and a temperature signal output by a battery; the battery output voltage signal is used for describing the voltage output by a battery on the electric vehicle; the temperature signal is used for describing the temperature of the control module; determining a first limiting current corresponding to the battery output voltage signal based on a voltage-limited power relationship; the voltage-limited power relationship is used for limiting the relationship between voltage and current on the basis of combining the residual electric quantity of the battery; obtaining a second limiting current corresponding to the temperature signal through a temperature-limited power relationship; the temperature-limited power relationship is used for describing the relationship between the temperature and the current on the basis of limiting the temperature of the control module; and adjusting the output current of the control module according to the first limiting current and the second limiting current to control the running power of the electric vehicle. Through the method, the problem that the motor cannot work normally due to the influence of voltage or temperature is avoided, and the user experience is optimized.

Description

technical field

[0001] The embodiments of this specification relate to the technical field of electric vehicles, and in particular to a power control method, device and processing circuit for electric vehicles. Background technique

[0002] With the development of science and technology and the advancement of manufacturing technology, electric vehicles, especially those used for cycling and transportation, have become an inaccessible part of people's lives. These electric vehicles can be private electric vehicles or shared electric vehicles, providing services for different users based on Internet of Things technology. In the process of using the electric vehicle, the control module is generally used to control the power supply to output a certain current to the motor, so that the motor runs and drives the electric vehicle to move.

[0003] At present, when an electric vehicle is riding, the power of the electric vehicle is generally adjusted by limiting the maximum output ...
