Problems solved by technology

[0003] In the case of being left unused for a long time or the power supply is damaged, the low-voltage power supply is prone to power loss, that is, the voltage power supply cannot supply power normally, and even the vehicle cannot be started.
When this happens, external resources are needed to help the low-voltage power supply, which is very troublesome; or replace the low-voltage power supply, but the low-voltage power supply is expensive, bulky, and heavy, and is not suitable for frequent replacement.

Abstract

The invention discloses a power feeding system for an electric vehicle, comprising: a power supply system, a switch system, and a voltage conversion device, wherein the power supply system includes: a low-voltage power supply and a high-voltage power supply, and the switch system includes: an ignition lock, a high-voltage trigger; a high-voltage power supply, The high-voltage trigger, the voltage conversion device, and the low-voltage power supply are connected in sequence, the ignition lock is respectively connected with the low-voltage power supply and the high-voltage trigger, and the high-voltage contactor is provided with a manual trigger device.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle power feeding system. Background technique [0002] With the advancement of science and technology and the improvement of environmental awareness, electric vehicles have attracted more and more attention. Electric vehicles have low-voltage power supplies and high-voltage power supplies. The low-voltage power supplies are mainly responsible for driving various control units, contactors, etc. Such as lights, wipers, etc.) power supply, the high-voltage power supply is mainly used to provide the power source of the whole vehicle, and drive the motor to drive the vehicle. [0003] When left unused for a long time or the power supply is damaged, the low-voltage power supply is prone to power loss, that is, the voltage power supply cannot supply power normally, and even the vehicle cannot be started. When this happens, external resources are needed to help the low-...
