Problems solved by technology

[0004] 1. It is troublesome to supplement electric energy. The charging of the battery on fuel vehicles is achieved through the engine driving the generator through a voltage regulator, which is relatively easy. On pure electric vehicles, it is only charged through the power battery pack through the main power supply DCDC / DC. Charging, in addition to self-discharge, there is also a large conversion loss during charging and discharging;
[0005] 2. The economy is poor, and additional equipment needs to be added;
[0006] 3. The installation volume is large, and the battery needs to occupy a certain volume, which increases the load and fuel consumption of the car at the same time

Abstract

The invention discloses a main power supply awakening device of an electric automobile. The device comprises a starting module, an action module, an enabling module and an auxiliary power supply module. The circuit structure of the main power supply awakening device is simple, the production cost is reduced, the awakening expansion use is not limited, meanwhile, through the adoption of the more compact circuit structure arrangement, the device use is reduced, and the self power consumption is further reduced. Compared with the auxiliary storage battery mode adopted by the existing electric automobile, the main power supply awakening device has the advantages that the size is smaller, the weight is lighter, the power loss in the work process is low, and the awakening speed is high.

Description

technical field [0001] The invention relates to a wake-up device for a main power supply of an electric vehicle. 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 is also required 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: [0004] 1. It is troublesome to supplement electric energy. The charging of the battery on fuel vehicles is achieved through the engine driving the generator through a voltage regulator, which is relatively easy. On pure electric vehicles, it is only charged through the power battery pack through the main power supply ...
