[0045] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0046] Figure 1A circuit structure schematic diagram of an automobile electric quantity adjusting system is provided for an embodiment of the present application, referring to Figure 1 The automobile electric quantity adjusting system comprises an automobile parameter detection circuit 11, which detects the temperature of a power battery of the automobile and the acceleration of the automobile in motion and generates an automobile parameter signal; and a control circuit 103, which adjusts the power consumption state of a direct current conversion component 104 according to the received automobile parameter signal.

[0047] Specifically, the direct current conversion component 104 can be used to convert the voltage of the power battery in the automobile into low voltage (such as 12V) to supply power to the low-voltage system in the automobile. The power of the direct current conversion component 104 is relatively high, generally about 3KW, and if it is always turned on, it will affect the electric quantity of the power battery and further affect the endurance of the automobile. In the embodiment, the automobile parameter detection circuit 11 is used to detect the temperature of the power battery and the acceleration of the automobile in motion. When the temperature of the power battery is lower than 0℃, the efficiency of the power battery of the automobile is relatively low, and when the acceleration of the automobile is relatively large, the torque demand of the automobile is relatively large, such as greater than 150NM, a first level automobile parameter signal can be generated. At this time, the automobile needs a relatively large acceleration, and if the power consumption state of the direct current conversion component 104 is still not limited, it will seriously affect the endurance mileage of the automobile. The control circuit 103 adjusts the power consumption state of the direct current conversion component 104 according to the received first level automobile parameter signal, thereby preferentially ensuring the endurance capability of the automobile and improving the endurance mileage of the automobile. Exemplarily, the first level can be a high level; and the power consumption state of the direct current conversion component 104 can include the target output voltage of the direct current conversion component 104, such as the control circuit 103 can turn off the direct current conversion component 104 or reduce the target output voltage of the direct current conversion component 104 according to the automobile parameter signal.

[0048] The technical scheme of the embodiment adopts the automobile electric quantity adjusting system comprising the automobile parameter detection circuit, the control circuit and the direct current conversion component. The automobile parameter detection circuit detects the temperature of the power battery of the automobile and the acceleration in motion and generates the automobile parameter signal. The control circuit adjusts the power consumption state of the direct current conversion component according to the received automobile parameter signal. When the temperature of the power battery is relatively low and the acceleration required by the automobile is relatively large, the direct current conversion component can be turned off or the target output voltage of the direct current conversion component can be reduced, thereby saving the electric energy of the power battery and improving the endurance capability.

[0049] Optionally, Figure 2 A circuit structure schematic diagram of another automobile electric quantity adjusting system is provided for an embodiment of the present application, referring to Figure 2The automobile parameter detection circuit comprises a battery temperature detection circuit 101, an acceleration detection circuit 102 and a control circuit 103.

[0050] Specifically, the battery temperature detection circuit 101 is used to detect the temperature of the power battery, and a first-level battery temperature signal is generated when the temperature of the power battery is lower than 0℃, at which the power battery has a low efficiency; the acceleration detection circuit 102 is used to detect the acceleration of the automobile and generate an acceleration signal, and a first-level acceleration signal is generated when the acceleration of the automobile is greater than 150NM, at which the automobile needs a large torque; and the control circuit 103 is electrically connected with the acceleration detection circuit 102 and the battery temperature detection circuit 101, and adjusts the power state of the DC conversion component 104 according to the received first-level battery temperature signal and first-level acceleration signal.

[0051] Optionally, Figure 3 A circuit structure schematic diagram of another automobile power adjustment system is provided for the embodiment of the present application, which is shown in Fig. 11. Figure 3 The automobile parameter detection circuit 11 comprises an acceleration detection circuit 102, a battery temperature detection circuit 101 and a control circuit 103.

[0052] Specifically, the acceleration detection circuit 102 detects the acceleration of the automobile and generates an acceleration signal, such as when the acceleration of the automobile is large, at which time the torque demand of the automobile is large, such as greater than 150 NM, a first level acceleration signal can be generated, at which time the automobile needs large acceleration, if the direct current conversion component 104 is still turned on, it will seriously affect the cruising range of the automobile; the battery temperature detection circuit 101 detects the temperature of the power battery according to the received first level acceleration signal, such as when the temperature of the power battery is lower than 0℃, the efficiency of the automobile power battery is low, at which time a first level battery temperature signal can be generated; the control circuit 103 adjusts the power state of the direct current conversion component 104 according to the received first level acceleration signal, at which time the direct current conversion component 104 is turned off, thereby preferentially ensuring the cruising ability of the automobile and improving the cruising range of the automobile. At the same time, the battery temperature detection circuit 101 detects the temperature of the automobile power battery only after the acceleration detection circuit 102 detects that the acceleration of the automobile is large, which avoids the battery temperature detection circuit 101 being always in the state of detecting temperature and consuming too much power of the power battery, further saves the electric energy and improves the cruising ability of the automobile.

[0053] Optionally, Figure 4 The circuit structure schematic diagram of another automobile electric quantity adjusting system provided by the embodiment of the present application is shown in FIG. 3, which is described as follows. Figure 4 The automobile parameter detection circuit includes a battery temperature detection circuit 101, which detects the temperature of the automobile power battery and generates a battery temperature signal; an acceleration detection circuit 102, which is electrically connected with the battery temperature detection circuit 101, detects the acceleration of the automobile according to the received battery temperature signal and generates an acceleration signal; and a control circuit 103, which is electrically connected with the acceleration detection circuit 102 and the direct current conversion component 104, adjusts the power state of the direct current conversion component 104 according to the received acceleration signal.

[0054] Specifically, the battery temperature detection circuit 101 detects the temperature of the power battery, for example, when the temperature of the power battery is lower than 0℃, the efficiency of the power battery is low, and a first-level battery temperature signal is generated; the acceleration detection circuit 102 detects the acceleration of the vehicle according to the received first-level battery temperature signal and generates an acceleration signal, for example, when the acceleration of the vehicle is large, the torque demand of the vehicle is large, for example, greater than 150 NM, a first-level acceleration signal is generated, and the vehicle needs large acceleration, if the DC conversion component 104 is still turned on, the cruising range of the vehicle will be seriously affected; the control circuit 103 adjusts the power state of the DC conversion component 104 according to the received first-level acceleration signal, so that the DC conversion component 104 is turned off at this time, thereby preferentially ensuring the cruising ability of the vehicle and improving the cruising range of the vehicle. At the same time, when the battery temperature detection circuit 101 detects that the temperature of the power battery is low to generate a battery temperature signal, the acceleration detection circuit 102 starts to detect the acceleration of the vehicle, which avoids the acceleration detection circuit 102 always being in the state of detecting the acceleration and consuming too much power of the power battery, further saves the electric energy, and improves the cruising ability of the vehicle.

[0055] Optionally, Figure 5 The circuit structure schematic diagram of another vehicle electric quantity adjusting system provided by the embodiment of the application is shown in FIG. 3, which is similar to the circuit structure schematic diagram of the vehicle electric quantity adjusting system shown in FIG. 1, and the difference is that the control circuit 103 of the vehicle electric quantity adjusting system shown in FIG. 3 includes a second comparison circuit 1032. Figure 5 The control circuit 103 includes a first comparison circuit 1031, the first comparison circuit 1031 is electrically connected with the acceleration detection circuit 102, the first comparison circuit 1031 includes a first comparison signal input end A1, a second comparison signal input end A2 and a first comparison signal output end A3; the first comparison signal input end A1 is connected with the acceleration signal, the second comparison signal input end A2 is connected with a first set acceleration signal, and the first comparison signal output end A3 outputs a first comparison signal to the DC conversion component 104.

[0056] Specifically, the first set acceleration signal can be the acceleration corresponding to the torque of 150 NM, when the torque demand is greater than 150 NM, the vehicle is in the acceleration stage, and the power battery needs to provide sufficient energy, if the DC conversion component 104 is still turned on at this time, the cruising ability of the vehicle will be seriously affected; therefore, when the acceleration signal is greater than the first set acceleration signal, that is, the torque demand is greater than 150 NM, the first comparison circuit 1031 can generate a first-level first comparison signal, and the DC conversion component 104 receives the first-level first comparison signal and is turned off, thereby reducing the overall power consumption of the vehicle and improving the cruising range when ensuring that the power battery provides sufficient energy to drive the vehicle to accelerate. For example, the first comparison circuit can use a comparator. It should be noted that, Figure 5For example, the control circuit is electrically connected with the acceleration detection circuit, the control circuit can also be electrically connected with the battery temperature detection circuit, or the control circuit can be electrically connected with both the battery temperature detection circuit and the acceleration detection circuit.

[0057] Optionally, with reference to the above description Figure 5 , the automobile power adjusting system further comprises a battery voltage detection circuit 105, the battery voltage detection circuit 105 is electrically connected with the control circuit 103, the battery voltage detection circuit 105 detects the voltage of the low-voltage battery of the automobile according to the received first comparison signal and generates a battery voltage signal; the control circuit 103 adjusts the power state of the direct current conversion component 104 according to the received battery voltage signal.

[0058] Specifically, the low-voltage battery can provide voltage signals to the components in the automobile, such as the radio and the interior light, and the output voltage of the low-voltage battery can be 12V; after the direct current conversion component 104 is closed by receiving the first comparison signal of the first level, the battery voltage detection circuit 105 can detect the voltage of the low-voltage battery in the automobile, and when the voltage of the low-voltage battery is too low, such as less than 11.5V, it will affect the normal use of the automobile, at this time, the control circuit 103 can open the direct current conversion component 104 according to the received battery voltage signal, thereby ensuring the normal use of the automobile.

[0059] Optionally, with reference to the above description Figure 5 , the control circuit 103 further comprises a second comparison circuit 1032, the second comparison circuit 1032 is electrically connected with the battery voltage detection circuit 105, the second comparison circuit 1032 comprises a third comparison signal input end B1, a fourth comparison signal input end B2 and a second comparison signal output end; the third comparison signal input end B1 is connected with the battery voltage signal, the fourth comparison signal input end B2 is connected with the set voltage signal, and the second comparison signal output end outputs the second comparison signal.

[0060] Specifically, the set voltage signal can be 11.5V, and when the voltage of the low-voltage battery is lower than 11.5V, it will affect the normal use of the automobile; therefore, when the battery voltage signal is lower than 11.5V, the second comparison circuit 1032 can generate the second comparison signal of the first level, the direct current conversion component 104 can be opened according to the second comparison signal, and the output voltage is set to 11.5V, thereby ensuring the normal work of the components in the automobile, such as the radio and the interior light, and also not consuming too much power and increasing the cruising range. If the battery voltage signal is higher than 11.5V, the second comparison circuit 1032 can generate the second comparison signal of the second level, and the direct current conversion component can not be opened, thereby improving the cruising range. Exemplarily, the second comparison circuit can adopt a comparator; the second level can be a low level.

[0061] Optionally, with reference to the above description Figure 5The control circuit 103 comprises a first state setting circuit 1033, which adjusts the power state of the DC conversion component 104 according to the received second comparison signal, and adjusts the target voltage of the DC conversion component to a first set voltage.

[0062] Specifically, the first set voltage can be 11.5V. When the battery voltage signal is lower than 11.5V, the second comparison circuit 1032 can generate a first level second comparison signal. The first state setting circuit 1033 adjusts the power state of the DC conversion component 104 according to the received first level second comparison signal, and adjusts the target voltage of the DC conversion component 104 to 11.5V, so as to ensure the normal work of the parts in the car, such as the radio and the light in the car, and also will not consume more power and increase the mileage.

[0063] Optionally, continuing to refer to Figure 5 The control circuit 103 comprises a third comparison circuit 106, which is electrically connected with the acceleration detection circuit 102. The third comparison circuit 106 comprises a fifth comparison signal input end C1, a sixth comparison signal input end C2 and a third comparison signal output end C3. The fifth comparison signal input end C1 is connected with the acceleration signal, the sixth comparison signal input end C2 is connected with a second set acceleration signal, and the third comparison signal output end outputs a third comparison signal.

[0064] Specifically, if the acceleration demand of the car is small, the DC conversion component 104 can be started to improve the driving experience of the car. At the same time, the second set acceleration signal can be set as the acceleration signal corresponding to the torque of 0NM. The third comparison circuit 106 compares the current acceleration of the car with the second set acceleration signal to generate different third comparison signals, so that the subsequent control circuit 103 can adjust the DC conversion component 104 to different states according to different third comparison signals, and expand the application range.

[0065] Optionally, continuing to refer to Figure 5 The control circuit 103 further comprises a switching switch 107, a second state setting circuit 108 and a third state setting circuit 109. The switching switch 107 selects the second state setting circuit 108 or the third state setting circuit 109 to adjust the power state of the DC conversion component 104 according to the received third comparison signal. The second state setting circuit 108 adjusts the power state of the DC conversion component 104, and adjusts the target voltage of the DC conversion component 104 to a second set voltage. The third state setting circuit 109 adjusts the power state of the DC conversion component 104, and adjusts the target voltage of the DC conversion component 104 to a third set voltage.

[0066] Specifically, when the current acceleration of the automobile is less than the second set acceleration signal, i.e. less than the acceleration corresponding to 0NM, it indicates that the automobile does not need to provide power to move forward, for example, when the automobile is in a deceleration state, the built-in brake recovery system in the automobile can collect the energy generated during braking, and the energy in the automobile is sufficient, the switching switch 107 receives the third comparison signal of the first level, and the second state setting circuit 108 adjusts the target voltage of the DC conversion component 104 to 13.5V according to the third comparison signal of the first level, so as to make up for the loss of the DC conversion component 104 in the acceleration stage. When the current acceleration of the automobile is greater than the second set acceleration signal, it indicates that the automobile needs small power to move forward, at this time the DC conversion component 104 will not significantly affect the cruising range of the automobile, the third comparison circuit 106 generates the third comparison signal of the second level, and the third state setting circuit 109 adjusts the target voltage of the DC conversion component 104 to 12.5V according to the third comparison signal of the second level, which will not seriously affect the cruising range of the automobile, and can improve the driving experience of the user.

[0113] Specifically, if the acceleration demand of the automobile is small, the DC conversion component can be turned on to improve the driving experience of the automobile; at the same time, the second set acceleration signal can be set as the acceleration signal corresponding to the torque of 0 NM, and the third comparison circuit compares the current acceleration of the automobile with the second set acceleration signal to generate different third comparison signals; when the current acceleration of the automobile is less than the second set acceleration signal, i.e. less than the acceleration corresponding to 0 NM, it indicates that the automobile does not need to provide power to move forward at present, for example, when the automobile is in a deceleration state, the built-in brake recovery system in the automobile can collect the energy generated during braking, and the energy in the automobile is sufficient, the switching switch receives the third comparison signal of the first level, and the second state setting circuit adjusts the target voltage of the DC conversion component to 13.5V according to the third comparison signal of the first level, thereby making up for the loss of the DC conversion component in the acceleration stage. When the current acceleration of the automobile is greater than the second set acceleration signal, it indicates that the automobile needs small power to move forward, at this time the DC conversion component will not significantly affect the cruising range of the automobile, the third comparison circuit generates the third comparison signal of the second level, and the third state setting circuit adjusts the target voltage of the DC conversion component to 12.5V according to the third comparison signal of the second level, which will not seriously affect the cruising range of the automobile, and can improve the driving experience of the user.

[0124] Specifically, the first set acceleration signal can be an acceleration corresponding to a torque of 150 NM. When the torque demand is greater than 150 NM, the vehicle is in an acceleration stage, and the power battery needs to provide sufficient energy.

[0139] The temperature of the power battery of the automobile and the driving acceleration of the automobile are detected by the automobile parameter detection circuit, for example, when the temperature of the power battery is lower than 0 DEG C, the efficiency of the power battery of the automobile is low, and when the driving acceleration of the automobile is large, the torque demand of the automobile is large, for example, greater than 150 NM, at this time, the automobile needs a large acceleration, if the power consumption state of the air conditioning system is not limited, the endurance mileage of the automobile will be seriously affected, at this time, the first level automobile parameter signal can be generated.

[0140] In step S402, the power consumption state of the air conditioning system is adjusted by the control circuit according to the received automobile parameter signal.

[0141] The air conditioning system can be used to heat or cool the car cabin. However, the air conditioning system consumes a large amount of power, which will seriously affect the cruising range of the car if it is always on. In the embodiment, the temperature of the power battery and the acceleration of the car are detected by the car parameter detection circuit. When the temperature of the power battery is lower than 0℃, the efficiency of the power battery is low. When the acceleration of the car is large, the torque demand of the car is large, such as greater than 150 NM, a first level car parameter signal can be generated. At this time, the car needs a large acceleration. If the power consumption state of the air conditioning system is not limited, the cruising range of the car will be seriously affected. The control circuit adjusts the power consumption state of the air conditioning system according to the received first level car parameter, so as to preferentially ensure the cruising ability of the car and improve the cruising range of the car. For example, the first level can be a high level. The power consumption state of the air conditioning system can include the target output power of the air conditioning system. For example, the control circuit can turn off the air conditioning system or reduce the target output power of the air conditioning system according to the car parameter signal.

If the air conditioning system is still turned on, it will seriously affect the cruising range of the car;

[0169] Optionally, Figure 14 Another flowchart of a vehicle power regulation method provided by an embodiment of the application is shown in FIG. 8; Figure 14 The vehicle power regulation method comprises:

[0170] Step S403, the battery temperature detection circuit detects the temperature of the vehicle power battery;

[0171] Step S404, the battery temperature detection circuit generates a battery temperature signal of the first level; if yes, step S405 is executed; if no, step S412 is executed;

[0172] Specifically, when the temperature of the automobile power battery is low, such as below 0°C, the efficiency of the power battery is low, and the battery temperature detection circuit generates a first level battery temperature signal.

[0173] In step S405, the first comparison circuit generates a first comparison signal of a first level; if yes, step S406 is executed; if no, step S412 is executed.

[0174] Specifically, the first set acceleration signal can be the acceleration corresponding to the torque of 150 NM. When the torque demand is greater than 150 NM, the automobile is in the acceleration stage, and the power battery needs to provide sufficient energy. If the direct current conversion component is still turned on at this time, it will seriously affect the endurance of the automobile. Therefore, when the acceleration signal is greater than the first set acceleration signal, that is, the torque demand is greater than 150 NM, the first comparison circuit can generate a first comparison signal of a first level.

[0175] In step S406, the difference signal is less than the first set difference signal; if yes, step S407 is executed; if no, step S413 is executed.

[0176] Specifically, the set temperature signal can be 25°C. The difference circuit subtracts the set temperature signal from the cabin temperature signal and sends the difference signal to the fourth comparison circuit. The first set difference signal can be 3°C. If the absolute value of the difference between the cabin temperature and the set temperature signal is less than the first set difference signal, it indicates that the temperature of the cabin at this time can make the driver more comfortable to drive. At this time, the fourth comparison circuit can generate a fourth comparison signal of a first level, and the control circuit can control the air conditioning system to be turned off. That is, step S407 is executed to turn off the air conditioning system; thereby saving the power of the power battery and improving the endurance mileage.

[0177] In step S408, the difference signal is greater than the second set difference signal; if yes, step S409 is executed; if no, step S407 is executed.

[0178] Specifically, after the air conditioning system is turned off, that is, after the fourth comparison circuit outputs a fourth comparison signal of a first level, the fifth comparison circuit can compare the difference signal with the second set difference signal. The second set difference signal can be 5°C. If the difference signal is greater than the second set difference signal, it indicates that the temperature of the automobile cabin at this time is high or low, and cannot provide a comfortable environment for the driver or passengers. At this time, the fifth comparison circuit 205 can generate a fifth comparison signal of a first level, and the control circuit turns on the air conditioning system according to the fifth comparison signal.

[0179] Step S409, the cabin temperature is higher than the set temperature signal; if yes, step S410 is executed, if not, step S411 is executed; step S410, the fourth state setting circuit adjusts the power-on state of the air conditioning system, and adjusts the target power of the air conditioning system to the first set power; step S411, the fourth state setting circuit adjusts the power-on state of the air conditioning system, and adjusts the target power of the air conditioning system to the first set power;

[0180] Specifically, the fourth state setting circuit can adjust the target power of the air conditioning system to the first set power, and the first set power can be 50% of the demand power. Thus, when the cabin temperature needs to be adjusted to 25℃, the target power of the air conditioning system for cooling can be adjusted to 50% of the power corresponding to 25℃ when the current cabin temperature is higher than the set temperature signal, and the target power of the air conditioning system for heating can be adjusted to 50% of the power corresponding to 25℃ when the current cabin temperature is lower than the set temperature signal. Thus, a comfortable driving environment can be provided, and the energy of the power battery is not wasted too much, and the endurance is improved.

[0181] Step S412, the power of the air conditioning system is not limited.

[0182] Step S413, the cabin temperature is higher than the set temperature signal; if yes, step S414 is executed, if not, step S415 is executed; step S414, the fifth state setting circuit adjusts the power-on state of the air conditioning system, and adjusts the target power of the air conditioning system to the second set power; step S415, the fifth state setting circuit adjusts the power-on state of the air conditioning system, and adjusts the target power of the air conditioning system to the second set power.

[0183] Specifically, the set temperature signal can be 25℃, the difference circuit subtracts the set temperature signal from the cabin temperature signal, and sends the difference signal to the fourth comparison circuit. The first set difference signal can be 3℃. If the absolute value of the difference between the cabin temperature and the set temperature signal is greater than the first set difference signal, it indicates that the temperature of the cabin at this time cannot make the driver more comfortable driving. At this time, the fourth comparison circuit can generate a second level fourth comparison signal, and the control circuit can control the air conditioning system to be turned on. When the current cabin temperature is higher than the set temperature signal, the target power of the air conditioning system for cooling is set to the second demand power, and the second set power can be 30% of the demand power. When the current cabin temperature is lower than the set temperature signal, the target power of the air conditioning system for heating is set to the second demand power, and the second set power can be 30% of the demand power. Thus, when the cabin temperature needs to be adjusted to 25℃, the target power of the air conditioning system can be adjusted to 30% of the power corresponding to 25℃. Thus, a more comfortable driving environment can be provided, and the energy of the power battery is not wasted too much, and the endurance is improved.
