In the related art, a high-voltage load in a hybrid electric vehicle includes a motor, a DCDC converter (DCDC, direct current to direct current) for converting high-voltage direct current into low-voltage direct current to supply power to electric equipment in the vehicle, an air conditioner management system, and the like. At present, a bidirectional charger is assembled on a hybrid electric vehicle, the bidirectional charger can charge a power battery when a charging gun is inserted, external discharging is carried out when a discharging gun is inserted, high-voltage direct current of a high-voltage battery is converted into alternating current of about 220V, and the alternating current is used by external equipment (namely, the vehicle is in an external discharging working condition, a V2L function is started, other loads are charged through the power battery, and the process is third party discharging). At present, for the management mode of the external discharge of the hybrid electric vehicle, when the V2L function is started, the hybrid electric vehicle is only used for continuously supplying power to external equipment, and when the electric quantity required by the external equipment is insufficient, no relevant solution exists. Meanwhile, under the condition that the vehicle high-voltage load, the air conditioning system and the external equipment are powered simultaneously, how to reasonably distribute the electric quantity of each electric equipment is not considered, so that a user can use various electric equipment simultaneously.
In order to solve the above problems, the present application proposes an energy management method for a vehicle, in an embodiment of the present application, a vehicle controller obtains an engine running state, a current state of charge of a power battery, first running data of a high-voltage load of the vehicle, and second running data of an external discharge gun; and the available power of the air conditioner is distributed according to the running state of the engine, the current state of charge of the power battery, the first running data and the second running data to determine the distributed power of the air conditioner. The whole vehicle controller sends the air conditioner distribution power to an air conditioner controller so that the power of the air conditioner controller when controlling the air conditioner to operate does not exceed the air conditioner distribution power; and balancing the power distribution among the electric equipment.
Embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, an energy management method of a vehicle, applied to a vehicle controller, includes:
and step S100, when the vehicle is in an external discharge working condition, responding to the fact that an air conditioner starting instruction is received, and acquiring the running state of an engine, the current state of charge of a power battery, first running data of a high-voltage load of the vehicle and second running data of an external discharge gun.
In this step, when the vehicle is in an outward discharge condition, the vehicle is in a stopped state, and the vehicle is inserted into a discharge gun for power use by an external load (for example, an external device such as an electric cooker, an illumination lamp, etc.). After receiving the air conditioner start instruction, the whole vehicle controller obtains the running State of the engine, the current State of Charge (namely the residual electric quantity SOC of the power battery), the first running data of the high-voltage load (such as a motor and a direct current converter) of the vehicle and the second running data of the external discharging gun, and the external discharging gun can be connected with external loads, such as external electric equipment of an electric cooker, an electric barbecue oven and the like. Because the air conditioner, the high-voltage load and the external discharging gun all need the vehicle to provide electric power energy, when the distribution power of the air conditioner is determined, the data are required to be acquired, so that the balance of the electric power distribution among the electric equipment can be ensured.
And step 200, determining air conditioner distribution power according to the running state of the engine, the current state of charge of the power battery, the first running data and the second running data.
In this step, the vehicle controller determines the air conditioner distribution power by distributing the available power of the air conditioner according to the operation state of the transmitter (e.g., engine started, engine not started), the current state of charge of the power battery, the first operation data (e.g., current output torque of the motor, current rotational speed of the motor, output voltage of the dc converter, output current of the dc converter, etc.), and the second operation data (e.g., current of the discharge gun, current voltage of the discharge gun, etc.), under the normal use condition of ensuring the external load.
And step S300, sending the air conditioner distribution power to an air conditioner controller so that the power of the air conditioner controller in the air conditioner operation control process does not exceed the air conditioner distribution power.
In the step, the whole vehicle controller sends the air conditioner distribution power to the air conditioner controller, and the air conditioner controller controls the air conditioner to operate according to the air conditioner distribution power, so that the power of the air conditioner during operation does not exceed the air conditioner distribution power; and balancing the power distribution among the electric equipment.
Specifically, the vehicle controller distributes the available power of the air conditioner according to the running state of the engine, the current state of charge of the power battery, the first running data of the high-voltage load of the vehicle and the second running data of the discharge gun in the steps S100-S300, and distributes the available power of the air conditioner under the condition of ensuring the normal use of the external load, so that the distributed power of the air conditioner is determined, and the problem that the external load cannot be normally used after a user starts the air conditioner when the vehicle is in an external discharge working condition is solved.
In some embodiments, referring to FIG. 2, in step S200, the engine operating conditions include engine on and engine off; the air conditioner distribution power comprises a first distribution power and a second distribution power;
the determining the air conditioner distribution power according to the engine running state, the current charge state of the power battery, the first running data and the second running data comprises the following steps:
step S210, responding to the engine running state as the engine starting, and determining the first distributed power according to a preset target state of charge, the current state of charge, the first running data and the second running data; or alternatively
And step S220, responding to the engine running state that the engine is not started, and taking the first preset power as the second distributed power.
Specifically, when the engine running state is engine starting, the electric quantity of the power battery is low, the discharging capability of the power battery is limited, and the available power is distributed to the air conditioner under the condition that the high-voltage load and the external load of the vehicle are used. And determining the available first distributed power of the air conditioner according to the preset target state of charge, the current state of charge, the first operation data and the second operation data.
When the engine is not started in the running state of the engine, the electric quantity of the power battery is higher, and the discharging capacity is higher, so that the use of a high-voltage load and an external load of a vehicle can be met, higher power can be distributed to an air conditioner, the first preset power is used as the second distributed power of the air conditioner, and the first preset power can be 5kw as an example.
In some embodiments, in step S210, the determining the first allocated power according to the preset target state of charge, the current state of charge, the first operation data, and the second operation data includes:
and in response to the current state of charge being higher than the target state of charge, determining the first allocated power according to the first operating data and the second operating data.
Specifically, when the vehicle is in the outward discharge condition, the vehicle is in the stopped state, and the power performance of the vehicle is not required to be ensured by the power battery as compared with when the vehicle is in the normal running condition, so that the value of the target state of charge of the power battery can be appropriately reduced when the target state of charge is set. For example, the target state of charge under normal driving conditions is 50%, and the target state of charge under outward discharging conditions may be reduced to 30%. The current state of charge is 50% and the target state of charge is 45%, and when the current state of charge is higher than the target state of charge, the discharging capability of the power battery is better, and the current state of charge is distributed according to the high-voltage load of the vehicle and the actual output power of the discharging gun to the available power of the air conditioner, and only the available first distributed power of the air conditioner is determined according to the first operation data and the second operation data.
In some embodiments, in step S210, the method further comprises:
and determining the first distributed power according to the first operation data, the second operation data and a second preset power in response to the current state of charge being lower than the target state of charge.
Specifically, for example, the current state of charge is 40%, and the target state of charge is 45%, and at this time, the current state of charge is lower than the target state of charge, which indicates that the discharging capability of the power battery is weaker, and the available power of the air conditioner needs to be distributed with lower power, so that the normal operation of other electric equipment can be ensured. And distributing the available power of the air conditioner according to the high-voltage load of the vehicle and the actual output power of the discharge gun, and determining the first distributed power of the available power of the air conditioner according to the first operation data, the second operation data and the second preset power.
When the running state of the engine is engine starting and the current state of charge is lower than the target state of charge, the lower discharge capacity of the power battery is indicated, and because the engine is started and the power battery is charged at the same time, the power battery is ensured not to continue to be powered down, the power battery is kept in the target state of charge as far as possible, and meanwhile, an external load is required to be powered, so that the normal running of the external load is ensured, the upper limit value of the available power of the air conditioner running is required to be further limited, namely, the highest available power is set to be the second preset power when the air conditioner is running.
In some embodiments, the high voltage load comprises a motor, a dc converter; the first operation data includes: the current output torque of the motor, the current rotating speed of the motor, the output voltage of the direct current converter and the output current of the direct current converter; the second operation data comprise the current of the discharge gun and the current voltage of the discharge gun;

Specifically, the whole vehicle controller obtains the current output torque of the motor, the current rotating speed of the motor, the output voltage of the direct-current converter, the output current of the direct-current converter, the current of the discharge gun and the current voltage of the discharge gun. Then, a relation formula of torque, rotating speed and power is utilized: output power (P) =2pi×rotational speed (n) ×torque (T), and the current output power of the motor is obtained by calculating from the current output torque of the motor and the current rotational speed of the motor.
Using the power calculation formula: power (P) =voltage (U) ×current (I), and the current output power of the dc converter is obtained by calculating from the output voltage of the dc converter and the output current of the dc converter.
Using the power calculation formula: power (P) =voltage (U) ×current (I), and the output power of the discharge gun is obtained by calculating from the current of the discharge gun and the current voltage of the discharge gun.
And (3) inputting the current output power of the motor, the current output power of the direct current converter, the current output power of the discharge gun and the reserved power into an air conditioner distribution power calculation formula (1) to obtain first distribution power.

In some embodiments, the high voltage load comprises an electric motor, an inverter; the first operation data includes: the current output torque of the motor, the current rotating speed of the motor, the output voltage of the direct current converter and the output current of the direct current converter; the second operation data comprise the current of the discharge gun and the current voltage of the discharge gun;

calculating according to the current output power of the motor, the current output power of the direct current converter, the current output power of the discharge gun and the reserved power to obtain actual available power;
and taking the smaller power of the actual available power and the second preset power as the first distribution power.
Specifically, the whole vehicle controller obtains the current output torque of the motor, the current rotating speed of the motor, the output voltage of the direct-current converter, the output current of the direct-current converter, the current of the discharge gun and the current voltage of the discharge gun. Then, a relation formula of torque, rotating speed and power is utilized: output power (P) =2pi×rotational speed (n) ×torque (T), and the current output power of the motor is obtained by calculating from the current output torque of the motor and the current rotational speed of the motor.
Using the power calculation formula: power (P) =voltage (U) ×current (I), and the current output power of the dc converter is obtained by calculating from the output voltage of the dc converter and the output current of the dc converter.

The formula (2) is: air conditioner distribution power=min (current output power of motor-current output power of dc converter-output power of discharge gun-reserve power, second preset power).
The reserved power is used for preventing the power battery from being damaged due to the fact that the discharge of the power battery exceeds the specified discharge capacity, so that the reserved power is set, and the discharge capacity of the power battery is ensured to be within the specified range.

And the whole vehicle controller receives an air conditioner starting instruction, and obtains the running state of the engine, the current state of charge of the power battery, the first running data of the high-voltage load of the vehicle and the second running data of the external discharge gun.
If the current state of charge (exemplary, the current state of charge is 50%) is higher than the target state of charge (exemplary, the target state of charge is 45%), the current output power (exemplary, 7 kw) of the motor is obtained by calculating according to the current output torque of the motor and the current rotational speed of the motor. The present output power of the dc converter (2 kw, for example) is calculated from the output voltage of the dc converter and the output current of the dc converter. The output power of the discharge gun is calculated from the current of the discharge gun and the current voltage of the discharge gun (exemplary, 660 w).

When the engine is not started in the running state, the electric quantity of the power battery is higher, the discharging capacity is higher, and therefore the high-voltage load and the external load of the vehicle can be met, and the available power of the air conditioner is distributed to be 5kw.
