Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In the related art, after receiving a charging reservation request input by a user, a vehicle automatically performs low-voltage power-on and high-voltage power-on after a period of time, and then judges whether the current electric quantity of the vehicle meets a target electric quantity required by the user. If so, controlling the vehicle to power off; and if not, controlling the vehicle to charge. Therefore, after the vehicle is electrified at high voltage, the vehicle is electrified again on the premise of not executing any operation, namely under the condition of no charging requirement, the electric quantity of a power battery on the vehicle is consumed, and thus the resource waste is caused; and the power battery comprises a high-voltage relay, and when the power battery is electrified and powered off at high voltage, the high-voltage relay is frequently closed and opened, so that the service life of the battery is also influenced.
In view of this, the present application provides a charging control method, where after a vehicle is powered on at a low voltage, a high voltage power on is not immediately performed, but a judgment between a current remaining power of the vehicle and a target power required by a user is performed first, and when the current remaining power of the vehicle is smaller than the target power required by the user and it is indicated that the remaining power does not meet the target power required by the user, the high voltage power on is performed, and a charging process is performed. Therefore, when a charging trigger request is received, whether high-voltage electrification is carried out or not is considered, and high-voltage electrification are not carried out when no charging requirement exists, so that the utilization rate of resources is improved, and the waste of the resources is reduced.
And when high-voltage electrification is not needed, high-voltage electrification is not carried out, and the high-voltage relay cannot be closed and opened, so that the service life of the power battery is prolonged.
Example one
Referring to fig. 1, there is shown a charge control method comprising:
step S1: and responding to the trigger request of charging, and performing low-voltage power-on the vehicle.
In this step, the vehicle is mainly a new energy vehicle, and after the new energy vehicle responds to the trigger request of charging, the vehicle is powered on at low voltage and then at high voltage. When the low-voltage power is on, the vehicle is powered by the storage battery; when the high voltage is electrified, the vehicle is powered by the power battery. The power battery comprises a high-voltage relay, and the high-voltage relay is closed when the power battery is electrified at high voltage and is disconnected when the power battery is electrified.
Step S2: determining the current residual capacity of the power battery of the vehicle and the target capacity required by the user.
In this step, the current remaining power of the Vehicle and the target power required by the user may be determined by a VCU controller (Vehicle control unit).
The current residual capacity of the vehicle can be monitored in real time through a Battery Management System (BMS), and the current residual capacity of the vehicle is sent to the VCU controller through the BMS; the target electric quantity required by the user can be set and stored through a HUT vehicle-mounted host (Head Unit System), and the stored target electric quantity required by the user is sent to the VCU controller.
Step S3: and under the condition that the current residual electric quantity of the vehicle is smaller than the target electric quantity required by the user, carrying out high-voltage electrification and starting charging.
In this step, when the VCU controller determines that the current remaining power of the vehicle is less than the target power required by the user, it indicates that the current remaining power of the vehicle cannot meet the target power required by the user, and therefore the power battery needs to be charged, and high-voltage power up is performed to meet the charging requirement.
After the high-voltage power-on is executed, in order to charge the vehicle in a reserved charging time period set by a user, a power battery of the vehicle is charged at the starting time of the reserved charging time period; after the vehicle is charged in the reserved charging time period, controlling the high voltage and the low voltage of the vehicle, so that the vehicle can charge the current residual electric quantity of the vehicle power battery to the target electric quantity set by a user in the preset charging time period set by the user.
Step S4: and under the condition that the current residual electric quantity of the power battery of the vehicle is not less than the target electric quantity required by the user, not carrying out high-voltage electrification.
In this step, when the VCU controller determines that the current remaining power of the vehicle is greater than the target power required by the user, it indicates that the current remaining power of the power battery of the vehicle meets the target power required by the user, and therefore, the vehicle does not need to be charged, and the high-voltage power-up is not performed.
After the vehicle is electrified at low voltage, the vehicle is not electrified at high voltage immediately, but the current residual electric quantity of the vehicle and the target electric quantity required by a user are judged firstly. Under the condition that the current residual electric quantity of the vehicle is smaller than the target electric quantity required by the user, high-voltage electrification is carried out, and a charging process is executed; and under the condition that the current residual electric quantity of the vehicle is larger than the target electric quantity required by the user, high-voltage power-on is not carried out.
Therefore, after the trigger request of charging is received, the high-voltage electrification can be carried out only by considering whether the power battery has the charging requirement or not, and the high-voltage electrification is not carried out immediately, so that the utilization rate of resources is improved, and the waste of the resources is reduced.
In a possible implementation manner, referring to fig. 2, the vehicle may be powered on at low voltage immediately after receiving a charging request from a user, or may be powered on at low voltage after timing a reserved charging time period set by the user. After receiving the reserved charging time period set by the user, the low-voltage power-on comprises the following steps:
and under the condition that the vehicle is normally connected with a charging gun, sending the charging trigger request according to the reserved charging time period of the vehicle.
When the vehicle is not normally connected with the charging gun, the situation that the vehicle is not chargeable is indicated, and a triggering request for charging cannot be sent according to a reserved charging time period of the vehicle; under the condition that the vehicle is normally connected with the charging gun, the charging gun indicates that the vehicle can be charged, and then a charging trigger request is sent according to a reserved charging time period of the vehicle, and the charging trigger method specifically comprises the following substeps:
substep A1: under the condition that the vehicle is normally connected with the charging gun, acquiring a preset time length between the current time of the reserved charging and the starting time of the reserved charging time period; wherein the starting time of the reserved charging time period is determined according to the reserved charging time period.
In this step, if the current time of the scheduled charging is 7:00, the scheduled charging time period is 9:00 to 12: 00, the starting time of the reserved charging period is 9:00, and accordingly, the preset time period from 7:00 to 9:00 is calculated as two hours.
Substep A2: and timing from the current moment of the reserved charging.
In this step, after the user sets the reserved charging time period from 7:00, the timer may be started from 7: 00.
Substep A3: and sending the charging trigger request when the timing duration reaches the preset duration.
In this step, after the timing is started from 7:00, if the timing duration reaches two hours, the charging trigger request is sent, and if the timing duration does not reach two hours, the timing is continued until the charging trigger request is sent for two hours.
In this embodiment, when the vehicle executes the reserved charging function, timing is performed first, and after the timing is completed, low-voltage power-on is performed, and after the low-voltage power-on, a determination process between the current remaining electric quantity and the target electric quantity of the vehicle is performed, and finally whether high-voltage power-on is performed is determined, and after the timing duration reaches a preset duration, high-voltage power-off is performed.
In the process, through the judgment process after the low-voltage power-on, when the vehicle executes the reserved charging function, whether the vehicle has the charging requirement or not can be judged by combining the actual situation between the current residual electric quantity and the target electric quantity of the vehicle, whether the vehicle is powered on at high voltage or not is finally determined, and the vehicle is powered on at high voltage immediately after the triggering request of charging is not received, so that the electric quantity of the power battery is saved, the influence on the power battery caused by frequent closing and opening of the high-voltage relay is reduced, and the service life of the power battery is prolonged.
