Description

Automobile quick charging control method, electronic equipment and storage medium
Technical Field
The invention relates to the technical field of automobiles, in particular to an automobile quick-charging control method, electronic equipment and a storage medium.
Background
The dark current of a new energy vehicle (for example, an electric vehicle) is a current that still flows when an ignition switch is in an OFF position (vehicle non-operating state). Due to the presence of these dark currents, and the natural discharge of the battery, the battery is easily fed and has a reduced service life.
At present, when a quick-charging gun of an electric automobile is inserted, a quick-charging port connection signal (CC 2) wakes up a Vehicle Control Module (VCM). When the card swiping signal is not detected for a certain time (for example, 3 minutes), or the charging is not authorized to be allowed by the mobile phone APP, the VCM is still in the state of cyclically detecting the card swiping signal and the remote charging allowing signal. The Controller Area Network (CAN) module of the VCM has a related function in a normal operation mode, and has a large power consumption.
As shown in fig. 1, the VCM1 'includes a direct current (DC-DC) power chip 11', a Micro Controller Unit (MCU) 12', and a Controller local area network module 13'. Wherein, the controller area network module 13' includes: vehicle body controller area network (V _ CAN) module 131', electric Vehicle controller area network (EV _ CAN) module 132', and Quick Charge controller area network (Quick Charge _ CAN, Q _ CAN) module 133'.
When VCM 1' is awakened after receiving the fast gun insertion signal. And then the VCM1 'starts to detect the charging card 4' detected by the charging pile 2 'and then sends a card swiping signal to the Q _ CAN module 133', and if the card is not swiped within a certain time, the detection is still performed circularly. Meanwhile, the MCU 12 'starts to detect a remote Control Unit (TCU) 3' and then sends a remote charging enable signal to the Q _ CAN module 133 'after detecting the signal of the mobile phone 5', and if not detected within a certain time, the remote charging enable signal is still detected cyclically. The card swiping signal and the remote charging permission signal are both CAN signals.
Meanwhile, the VCM1 'opens the DC-DC power supply chip 11', the MCU 12 'kernel, the system clock, the external interrupt, and opens the V _ CAN module, the Q _ CAN module function and the corresponding clock, so that when swiping the card again, the VCM 1' CAN recognize the swiping card sent on the Q _ CAN or the remote charging permission signal sent by the mobile phone APP. On the other hand, VCM turns off Analog Input (AI)/Digital Input (DI)/Low dropout regulator (LDO)/Low Side Driver (LSD)/High Side Driver (HSD)/EV _ CAN to enter the Low power mode.
And when the card swiping signal or the remote charging permission signal is re-identified, entering a normal quick charging mode until the charging is finished.
Therefore, in the quick charging control method in the prior art, under the working condition that the quick charging gun is inserted, whether card swiping or remote charging is allowed, most functional modules of the VCM vehicle controller, such as a DC-DC power supply chip, an MCU kernel, an interrupt module, a clock module, an IO detection module and a CAN communication module, work, consume a large dark current (about 50 mA), and therefore the durable feeding service life of the storage battery is shortened.
