Embodiment Construction

[0019] Below with reference to the accompanying drawings, through the description of the implementation examples, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between each part, the role and working principle of each part, etc., will be further described. detailed instructions.

[0020] like figure 1 , 2 , the automobile power supply control mode of the present invention includes the following three states:

[0021] OFF state: the start button relay is disconnected, and the vehicle power is cut off; in the OFF state, the charging gun can be inserted, and the controller can be charged through the CAN bus network wake-up;

[0022] ON state: In the OFF state, press the start button, and proceed to the steps: ①, KL15 and KL30 conduction and charging, and the low-voltage electrical equipment on the KL15 circuit can be used; ②, each on-board controller performs initialization and self-test; including a...

Abstract

The invention provides a novel battery electric vehicle power supply control mode. The control mode can simplify the operation processes of electrifying and discharging of a battery electric vehicle,improve the user experience, prevent a storage battery from feeding, and prolong the service life of the storage battery. According to the mode, the power supply mode of an existing automobile is simplified into three modes of OFF, ON and Ready from four modes of OFF, ACC, ON and START, due to the fact that a power supply button is not required to be pressed by the Ready, a power supply only has two modes of opening and closing for a user, the power supply mode is reduced, so that a user does not need to pay attention to power supply gears, the power supply can be used by turning on a switch,and the experience effect of the user is improved; and the ON state and the Ready state are redefined, during the ON state, the low-voltage storage battery is charged by a direct-current transformer in real time to prevent the storage battery from feeding, so that the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a power supply control mode of pure electric vehicles. Background technique [0002] Today's mainstream vehicle power mode design still follows the four power distribution modes of traditional fuel vehicles: OFF, ACC, ON and START. The original intention of the design of this power supply mode is to take into account the characteristics of the engine, to avoid the waste of energy consumption caused by the power generation when the engine is idling, the carbon deposition of the engine and the pollution of the exhaust environment. [0003] With the advancement of automotive electronics technology, such as the application of CAN network management technology, the controller can wake up and sleep through network management, and does not need to rely on switching power distribution methods to achieve wake up and sleep. More importantly, pure electric vehicles no longer...
