Abstract

The invention discloses a high-voltage control system and method of an electric automobile and the electric automobile. The system comprises a power battery pack, a high-voltage control switch, a battery managing device and an outage delaying module. The power battery pack is connected with high-voltage load through the high-voltage control switch. The battery managing device used for managing the power battery pack is connected with the high-voltage control switch so as to control on-off of the high-voltage control switch. The outage delaying module is connected with the battery managing device and is used for receiving a key signa of the automobile; and when the key signal is a disconnection signal, after delaying the pre-set time, the outage delaying module sends a disconnection instruction to the battery managing device so that the battery managing device can control on-off of the high-voltage control switch. According to the high-voltage control system of the electric automobile, driving experience of a user can be ensured, and meanwhile, safety of the electric automobile can be ensured.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a high-voltage control system and control method of the electric vehicle and the electric vehicle. Background technique [0002] Electric vehicles have the advantages of energy saving and environmental protection. With the improvement of people's awareness of environmental protection, electric vehicles are becoming more and more popular. [0003] At present, most electric vehicles perform high-voltage power-on and high-voltage power-off through the operation of the key. During the actual use of electric vehicles by users, users often make wrong operations. When the electric vehicle is running, if the user mistakenly sends a power-off signal through the key, the power supply of the power battery to the high-voltage load will be disconnected immediately, which will cause the electric vehicle to lose the energy required for driving and control, bringing users Bad driving...
