Abstract

The invention discloses a power on and of control method of an electric automobile. A high-voltage power on control method comprises the steps that high-voltage power on is based on the premise that low-voltage power on is succeeded, after a high-voltage power on request is detected by VCM, the high-voltage power on process is executed, the priority of the charging high-voltage power on request is higher than that of a key signal, and when high-priority power on timing sequence is triggered, high-voltage power on cannot be conducted due to the fact that requirements are not met, even if low-priority power on requirements are met, high-voltage power on is not conducted. Therefore, high-voltage power on is divided into traveling high-voltage power on, trickle charge high-voltage power on and fast charge high-voltage power on. By means of the method, the problems that once a driver is inconsiderate or the timing sequence is incorrect, a high-voltage system is likely to break down or even be damaged, and in severe case, the personal safety of the driver might be affected are solved.

Description

technical field [0001] The invention relates to the technical field of electric vehicle manufacturing, in particular to a control method for powering on and off the electric vehicle. Background technique [0002] Compared with traditional vehicles, electric vehicles have a set of high-voltage drive systems (including high-voltage power batteries, inverters, power motors and three-electric control systems). The coordinated control among the high-voltage relays in the high-voltage system and the prerequisites that need to be considered are the key points to ensure the normal operation of electric vehicles. [0003] The power-on and power-on management of electric vehicles includes low-voltage power-on and power-on sequence management and high-voltage power-on and power-on sequence management. Normal low-voltage power-on is a prerequisite for high-voltage power-on. When powering on at low voltage, you need to consider its power-on conditions and priority; when you power on at ...
