It should be noted that the power supply of the vehicle is divided into four gears of the normal power, the ACC, the ON and the CRANK, and when the power supply of the vehicle is in the ACC or ON gear, the power supply control module 100 is configured to obtain the remaining power of the storage battery, determine a control instruction for controlling the power-ON state of the electrical appliance corresponding to each priority according to a plurality of preset power ranges and the remaining power, send the control instruction to the distribution box 200, and control the power-ON state of the electrical appliance to instruct the electrical appliance to supply power to the electrical appliance or stop supplying power to the electrical appliance.
The remaining capacity is a State of Charge (SOC) of the battery.
In a specific implementation, the power control module 100 obtains the remaining power of the storage battery through a Controller Area Network (CAN) bus.

The communication between the power control module 100 and the distribution box 200 may be performed through a hard wire, or may be performed through other methods, and is not limited in particular.
It can be understood that the electrical loads in the automobile are divided into high and low priority levels in advance, wherein the high and low priority levels indicate the importance of the functions of the electrical loads in the automobile, that is, the higher priority level of the functions of the electrical loads in the automobile is.
For example, electrical appliances in an automobile are divided into electrical appliances corresponding to a first priority, electrical appliances corresponding to a second priority and electrical appliances corresponding to a third priority according to the priority, wherein the priority of the first priority is the highest, the priority of the first priority is the second priority, and the priority of the third priority is the lowest. That is to say, the electrical equipment function corresponding to the first priority has the highest importance in the vehicle, the electrical equipment function corresponding to the second priority is used, and the electrical equipment function corresponding to the third priority has the lowest importance in the vehicle.
It should be understood that the above-mentioned division of the priorities of the electrical appliances in the automobile is only used for illustration, and the electrical appliances in the automobile may be divided according to actual situations, and is not limited specifically herein.
For better explanation, the above description about the electrical appliances corresponding to the first priority, the second priority and the third priority is illustrated by the contents in table 1, and the contents in table 1 are only for example.
Table 1:
Figure BDA0002478404120000061
the specific content of the english abbreviations in table 1 is: an Electronic Control Unit (ECU), a keyless Entry and Start System (PEPS), a vehicle Body Control Module (BCM), an Advanced Driving Assistance System (ADAS), and an Electronic Brake System (EBS).
As can be seen from the foregoing, the distribution box 200 can control the power-on state of the electrical appliance corresponding to each priority, and it can be understood that a plurality of groups of switches are disposed in the distribution box 200, each group of switches is used to control the power-on state of the electrical appliance corresponding to the priority corresponding to the group of switches, that is, one group of switches controls the power-on state of the electrical appliance corresponding to one priority.
For example, the distribution box 200 includes at least a first switch, a second switch and a third switch, and the connection relationship between the distribution box 200 and the battery and the electrical appliance is shown in fig. 3.
Referring to fig. 3, a schematic diagram of the connection between the distribution box and the electrical appliance and the storage battery according to the embodiment of the present invention is shown.
In fig. 3, the distribution box 200 includes a first switch 201, a second switch 202, and a third switch 203, where the first switch 201 is connected to the battery and the electrical appliance corresponding to the first priority, the second switch 202 is connected to the battery and the electrical appliance corresponding to the second priority, and the third switch 203 is connected to the battery and the electrical appliance corresponding to the third priority.
In a specific implementation, first terminals of the first switch 201, the second switch 202, and the third switch 203 are connected to a positive electrode of the battery, and a negative terminal of the distribution box 200 is connected to a negative electrode of the battery. The second end of the first switch 201 is connected to the positive electrode of the electrical appliance corresponding to the first priority, the second end of the second switch 202 is connected to the positive electrode of the electrical appliance corresponding to the second priority, the second end of the third switch 203 is connected to the positive electrode of the electrical appliance corresponding to the third priority, and the negative electrodes of the electrical appliances corresponding to the priorities are connected to the negative electrode port of the distribution box 200.
Control ends of the first switch 201, the second switch 202 and the third switch 203 are connected with the power control module 100.
By combining the above contents, the power-on state of the electrical appliances corresponding to any priority can be controlled independently, and the mutual independence of the power supply circuits among the electrical appliances corresponding to different priorities is ensured.
It should be noted that the charge amount (0% to 100%) of the storage battery is divided into a plurality of charge amount ranges in advance, for example, the charge amount of the storage battery is divided into a first charge amount range (a% to 100%), a second charge amount range (b% to a%), a third charge amount range (c% to b%) and a fourth charge amount range (0% to c%), where a is greater than b, and b is greater than c.
It should be further noted that the setting of the specific values of a, b, and c described above needs to be set according to the influence of the parameters of the starter of the automobile, the parameters of the battery, and the ambient temperature, the specific values of a, b, and c are directly proportional to the starting current of the starter, and the specific values of a, b, and c are inversely proportional to the starting performance of the battery and the ambient temperature.
For example: a is set to 90, b is set to 80, and c is set to 70, and the setting of specific numerical values regarding a, b, and c is not particularly limited herein.
In combination with the above content related to the division of the priority of the electrical appliance and the division of the electric quantity range, in a specific implementation, the power supply control module 100 for determining the control instruction is specifically configured to:
and if the residual electric quantity is within the first electric quantity range, determining a first control instruction for supplying power to the electric appliance corresponding to each priority.
That is to say, the power control module 100 sends a first control instruction to the distribution box 200, and the distribution box 200 closes the first switch, the second switch, and the third switch according to the first control instruction, so that the storage battery supplies power to the electrical appliance corresponding to each priority.
And if the residual electric quantity is within the second electric quantity range, determining a second control instruction for supplying power to the electric appliance corresponding to the first priority, supplying power to the electric appliance corresponding to the second priority and stopping supplying power to the electric appliance corresponding to the third priority.
That is to say, the power control module 100 sends the second control instruction to the distribution box 200, and according to the second control instruction, the distribution box 200 closes the first switch and the second switch, so that the storage battery supplies power to the electrical equipment corresponding to the first priority and the second priority, and opens the third switch, so that the storage battery stops supplying power to the electrical equipment corresponding to the third priority.
And if the residual electric quantity is within a third electric quantity range, determining a third control instruction for supplying power to the electric appliance corresponding to the first priority, stopping supplying power to the electric appliance corresponding to the second priority and stopping supplying power to the electric appliance corresponding to the third priority.
That is to say, the power control module 100 sends the third control instruction to the distribution box 200, and according to the third control instruction, the distribution box 200 closes the first switch to enable the storage battery to supply power to the electrical appliance corresponding to the first priority, and disconnects the second switch and the third switch to enable the storage battery to stop supplying power to the electrical appliance corresponding to the second priority and the third priority.
And if the residual electric quantity is within a fourth electric quantity range, determining a fourth control instruction for stopping power supply to the electric appliance corresponding to the first priority, stopping power supply to the electric appliance corresponding to the second priority and stopping power supply to the electric appliance corresponding to the third priority.
That is to say, the power control module 100 sends a fourth control instruction to the distribution box 200, and the distribution box 200 disconnects the first switch, the second switch and the third switch according to the fourth control instruction, so that the storage battery stops supplying power to the electrical appliances corresponding to the first priority, the second priority and the third priority.
Through the mode, along with the reduction of the residual electric quantity of the storage battery, the power supply for the electric appliance is gradually stopped according to the priority level, and the residual electric quantity of the storage battery is ensured to be enough to support the whole automobile starting and safe operation of the automobile.
To better explain the above-mentioned control of the open/close states of the switches in the distribution box 200 according to the remaining power and the plurality of power ranges, the division diagram of the power ranges shown in fig. 4 is used for illustration, and it should be noted that the content in fig. 4 is used for illustration only.
In fig. 4, when the remaining capacity is greater than a%, the first switch, the second switch, and the third switch in the distribution box 200 are in a closed state. When the residual capacity is less than or equal to a% and greater than b%, the third switch is in an open state, and the first switch and the second switch are in a closed state. When the residual capacity is less than or equal to b% and greater than c%, the second switch and the third switch are in an open state, and the first switch is in a closed state.
