Problems solved by technology

[0003] At present, the method of adding an auxiliary 12V battery is usually used to meet these operations on pure electric vehicles, but this technology has the following shortcomings: (1) It is troublesome to supplement electric energy. The charging of the battery on fuel vehicles is driven by the engine through the generator It is relatively easy to realize the voltage regulator, but in the pure electric vehicle, it can only be charged by the power battery pack through the main power supply DC / DC. In addition to self-discharge, there is also a large conversion loss during charging and discharging; (2) Poor economy; (3) Large installation volume

Abstract

The invention discloses a wake-up device for a main power supply, and belongs to the field of electrical vehicles. The wake-up device consists of a wake-up module and an auxiliary power module, wherein, the auxiliary power module receives stored power provided by a storage battery, converts the stored power into first voltage and second voltage, and then provides the first voltage and the second voltage to the wake-up module; and the wake-up module receives a key switch signal and an action switch signal set, outputs an enabling signal according to the key switch signal and the action switch signal set, and controls conversion of the main power supply between an operating state and a dormant state. The wake-up device has the advantages of small installation volume, low power loss and capability of quickly waking up the main power supply.

Description

technical field [0001] The invention relates to an auxiliary power supply device of a power supply system, in particular to a main power wake-up device of a pure electric vehicle power supply system. Background technique [0002] In terms of fuel vehicles, when the driver stops and takes the key, he can also operate the remote control, emergency lights, interior lights, horns, etc. The same function must be provided for electric vehicle parking, and it is also required to provide protection voltage for the information that needs to be memorized on the vehicle. [0003] At present, the method of adding an auxiliary 12V battery is usually used to meet these operations on pure electric vehicles, but this technology has the following shortcomings: (1) It is troublesome to supplement electric energy. The charging of the battery on fuel vehicles is driven by the engine through the generator It is relatively easy to realize the voltage regulator, but in the pure electric vehicle, ...
