Abstract

The invention provides a low-voltage power-off control method, a device and an electric vehicle, and relates to the technical field of vehicle control. The low-voltage power-off control method comprises the steps of receiving a low-voltage power-off instruction; detecting a program running state; under the condition that the program running states are all in the release state, controlling the electrified erasable programmable memory to execute write operation; and when the electrified erasable programmable memory EEPROM is in a release state, low-voltage power-off is controlled. According to the scheme, the low-voltage power-off process is completed quickly, efficiently and safely.

Description

Technical field [0001] The present invention relates to the field of vehicle control technology, and more particularly to a low pressure lower electrical control method, apparatus and an electric vehicle. Background technique [0002] In the prior art, the electric vehicle's lower electricity control is mostly controlled by high voltage, and there is almost no solution to electric vehicles under low voltage electricity, however, electric vehicles electronic control unit, such as vehicle controller , Battery management system controller and motor controller, etc., as the brain of electric vehicles, coordinates the power domain of the vehicle, playing a crucial role in the entire vehicle driving cycle, can safely, quickly guiding the whole vehicle is more Important link. Inventive content [0003] It is an object of the present invention to provide a low-voltage lower electrical control method, apparatus, and electric vehicle, thereby solving problems in which the prior art cannot...
