Problems solved by technology

In the normal running state of the vehicle, there is no use problem due to the DC-DC converter power supply, but when the vehicle is idle for a period of time, the battery of the vehicle will lose power after a period of time due to the increase in static power consumption, which will cause the vehicle to Unable to start
Due to the increase of electronic components in new energy vehicles, it is difficult to meet the requirements of the vehicle only by increasing the battery capacity.

Embodiment Construction

[0013] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0014] figure 1 It is a schematic diagram of the vehicle starting system of the present invention. like figure 1 As shown, the battery 103 supplies power to the vehicle controller 105 and the DC-DC converter 102. When the key is turned to the ACC (not shown) position, the vehicle controller 105 receives an enable signal and is activated to start working. ; At this time, the vehicle controller 105 sends an enabling signal to the DC-DC converter 102 to start the DC-DC converter, and the DC-DC converter 102 provides electric energy for starting the vehicle. However, when the vehicle is idle for a long time, the storage battery 103 will run out of power due to th...

Abstract

The invention discloses a starting system for a new energy vehicle. The system includes: a DC-DC converter, which converts the high voltage of a power battery into a low voltage, and outputs the low voltage; The DC-DC converter is connected to control the DC-DC converter; the storage battery is used to supply power to the vehicle controller and the DC-DC converter when the new energy vehicle starts normally; and The auxiliary power supply is connected to the DC-DC converter and the storage battery, and is used to supply power to the vehicle controller and the DC-DC converter when the storage battery fails to supply power.

Description

technical field [0001] The present invention relates to the field of automobiles, in particular to a starting system for new energy vehicles. Background technique [0002] With the increasing development of automobile technology, the electronic components on new energy vehicles have increased significantly, resulting in an increase in low-voltage power consumption, and the problem of battery power loss has become increasingly apparent. In the normal running state of the vehicle, there is no use problem due to the DC-DC converter power supply, but when the vehicle is idle for a period of time, the battery of the vehicle will lose power after a period of time due to the increase in static power consumption, which will cause the vehicle to Unable to start. Due to the large number of electronic components added to new energy vehicles, it is difficult to meet the requirements of the vehicle only by increasing the battery capacity. And a kind of system that the present invention...
