Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, the scheme relates to a charging control system with an adjustable charging target, which is composed of a battery management unit BCU4, a vehicle control unit VCU3, a vehicle-mounted communication controller Tbox2, a man-machine interaction device 1 and a meter 5, wherein the man-machine interaction device 1 is connected with the vehicle-mounted communication controller Tbox2 through a CAN network, the vehicle-mounted communication controller Tbox2 is connected with the vehicle control unit VCU3 through the CAN network, and the vehicle control unit VCU3 is connected with the battery management unit BCU4 and the vehicle-mounted meter 5 through the CAN network. Wherein, human-computer interaction device 1 is in car machine HU and cell-phone APP one kind. With the above system, it is possible to artificially adjust the charging target (charging target SOC and charging current limit) of the vehicle and charge the vehicle in accordance with the artificially adjusted charging target.
The vehicle-mounted communication controller Tbox2 receives the charging target SOC value and the charging current limit value sent by the vehicle-mounted HU and the mobile phone APP and then stores the latest value; after the whole vehicle is powered on, the stored latest value is sent to the CAN bus, the vehicle control unit VCU3 converts the charging target SOC sent by the vehicle communication controller Tbox2 into a target value of the actual target SOC of the battery and sends the target value to the battery management unit BCU4, and the battery management unit BCU4 charges according to the charging target SOC and calculates the residual charging time.
Car machine HU or cell-phone APP should provide the target SOC that charges and set up the interface, and the user can set up following target SOC that charges through car machine HU or cell-phone APP's human-computer interaction interface: when the charging target SOC is within the range of 60% to 90% [ 60%, 65%, 70%, 75%, 80%, 85%, 90%, 92%, 94%, 96%, 98%, 100% ], the vehicle control unit VCU3 displays a long-life mode (long-life mode indicates a mode in which the charging life of the vehicle can be extended by setting a value lower than 90% as the charging target SOC value) by the meter 5; when the charging target SOC is 90% or more, the vehicle control unit VCU3 displays the long-distance mode (the long-distance mode indicates a mode in which the current mileage of the vehicle can be maximized with 90% as the charging target SOC value) by the meter 5. When the vehicle is powered off, the vehicle control unit VCU3 saves the charging target SOC, and when the vehicle is powered on again, the default value is 100% based on the stored value. When the ignition key state of the vehicle is changed from the ON/START gear to the OFF/ACC gear, the vehicle control unit VCU3 controls the ON-vehicle meter 5 to output information prompting the user that "the current charging target SOC is XX" for a certain time (initial value 60 s).
The car HU or the mobile terminal as the human-computer interaction device 1 should provide an interface for setting the ac charging limit value for the same user, and the user can set the following charging current limit value through the interface: [ 8A, 10A, 16A ]. When the ignition key state of the vehicle is changed from the ON gear or the START gear or from the OFF gear or the ACC gear, the vehicle controller VCU3 controls the meter 5 to output a message prompting the user that the "current charging current limit is XX" for a certain time (initial value 60 s).
After a user sets a charging target SOC and a charging current limit value on a car HU or a mobile phone APP, the car HU or the mobile terminal APP sends the charging target SOC and the charging current limit value to a vehicle-mounted communication controller Tbox2 periodically, the vehicle-mounted communication controller Tbox2 saves the charging target SOC and the charging current limit value, and the charging target SOC and the charging current limit value are sent to a CAN bus after the whole car is powered on. When the charging target SOC and the charging current limit value set by the car-mounted device HU or the mobile phone APP change, the vehicle-mounted communication controller Tbox2 saves and transmits the latest value of the two. The vehicle-mounted communication controller Tbox2 feeds back the charging target SOC and the charging current limit value to the vehicle-mounted communication controller HU and the mobile phone APP to serve as the basis of whether the target SOC is set successfully or not, and data synchronization is carried out.
The vehicle control unit VCU3 converts the charging target SOC sent by the vehicle-mounted communication controller Tbox2 into a target value of the actual target SOC of the battery according to the mapping relation between the actual target SOC of the battery and the charging target SOC of the battery, and sends the target value of the actual target SOC of the battery to the battery management unit BCU 4.
The vehicle control unit VCU3 sends an ac charging limit to the battery management unit BCU4 that cannot exceed the user set current limit.
In the charging process, the battery management unit BCU4 receives the target value of the actual SOC of the battery sent by the vehicle control unit VCU3, and if the charging target SOC changes, the battery management unit BCU4 should use the latest charging target SOC as the charging completion SOC and calculate the charging remaining time, and when the actual SOC of the battery is judged to be greater than or equal to the charging target SOC, the charging is judged to be completed, and the charging process is ended.
In the charging completion state, if the charging target SOC transmits a change and the charging target SOC is larger than the current SOC, the battery management unit BCU4 reenters the charging state.
During the ac charging process, the battery management unit BCU4 should ensure that the ac input current does not exceed the charging current limit of the vehicle control unit VCU 3.
In the embodiment, when a user needs to go far, the user can set a long-mileage mode (namely, set the charging target SOC value to be 100%) to meet the requirement on long mileage; when mileage is not pursued, a long-life mode can be set (namely, the charging target SOC value is set to be less than 100 percent), and the effect of prolonging the service life of the battery is achieved; the magnitude of the alternating current charging current can be set according to needs, and the effect of charging and protecting the battery with low current and prolonging the service life is further achieved.
