In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It will be apparent that the described embodiments are some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In order to meet the electricity demand of a user, the common equipment for outdoor electricity consumption is a mobile power supply such as a charger, a small electricity and the like, the existing problems are often concentrated on the mobile power supply with limited power supply quantity, the mobile power supply is difficult to regenerate after being used up, the mobile power supply is charged in advance, the power is limited and cannot be adjusted according to the demand, a vehicle-mounted power supply mode is adopted, a vehicle engine is used for driving a generator to generate electricity, the electric energy is stored in a storage battery, and when the mobile power supply is needed, the storage battery is used for supplying power for the vehicle-mounted electric equipment and also can supply power for external equipment, so that the electricity regeneration problem can be solved.

The generator is a main vehicle power supply device, and charges the storage battery on the premise of not influencing the normal running of the vehicle. That is, when the engine is operating normally, almost all the electric energy on the vehicle is provided by the generator, the generator charges the storage battery, and the output power of the generator of the vehicle ranges from 0.8 kilowatts to 1.5 kilowatts, so that the electric power requirement of the vehicle can be met under most conditions.

The storage battery is the largest electricity storage device on the vehicle, and mainly aims to supply power to main electric equipment such as a starter, an ignition system and the like when an engine is started; when the engine is not running or running at low speed, power is supplied to various electric equipment; when the electric equipment is too much and the electricity consumption exceeds the power supply capacity of the generator, the storage battery assists the generator to supply power to various electric equipment.

The research shows that most of the generators used on vehicles are three-phase silicon-rectifying alternators, and the main structure of the generators is composed of a rotor, a stator, a three-phase bridge rectifier, a bearing and the like, wherein the rotor is used for generating a magnetic field, the stator is used for generating current, the rectifier converts the three-phase alternating current into direct current pulsating voltage, and the generated energy of the generators is increased along with the rising of the rotating speed of the engine.

In view of the above important findings, the present embodiment proposes a vehicle-mounted power supply method, and at the same time, the method needs to consider the characteristics of the power supply system of the vehicle itself and consider the fuel quantity factor of the vehicle. Specifically, the method has the following core technical conception: based on the existing vehicle-mounted power supply architecture, the vehicle-mounted power supply mode provides output power meeting the power demand of a user by adjusting the rotating speed of the engine to drive the generator to supply power under the condition of not changing any hardware facilities and circuit structures, so that the power supply can be flexibly performed.

One embodiment of the present application relates to a vehicle-mounted power supply method, as shown in fig. 1, comprising the steps of:

step 101, a control command for starting vehicle-mounted power supply is obtained.

In the present embodiment, a control command for the vehicle to start the power supply mode is acquired by the vehicle management system. The vehicle management system is used as a control unit of the whole vehicle, has functions of running management, motor, battery coordination management and the like, can acquire a control command for starting vehicle-mounted power supply according to a signal of triggering a one-key power utilization mode by a user or a power supply demand signal detected by a vehicle, wherein the one-key power utilization mode can be set by a vehicle-mounted terminal, the user starts the vehicle-mounted power supply by triggering a setting option, and the vehicle management system receives the triggering signal to acquire the control command.

The present embodiment does not limit the triggering of the started vehicle-mounted power supply, and in the actual use process, any signal that can uniquely indicate the start of the vehicle-mounted power supply may be used.

According to the embodiment, the power supply mode can be automatically started according to the starting control command, so that user operation is simplified, and when the vehicle-mounted power supply needs to be started, the vehicle-mounted power supply is quickly and directly started, and the power consumption needs of users are met.

Step 102, obtaining output power of the generator in case the control command indicates that the generator is driven by the engine to supply power.

In the present embodiment, the generator is a main vehicle power supply device, and the generator charges or supplies power to the battery without affecting the normal running of the vehicle. That is, when the engine is operating normally, almost all of the electrical energy on the vehicle is provided by the generator, and the output power of the vehicle generator ranges from 0.8 to 1.5 kw.

In the embodiment, the engine drives the generator to supply power, after the vehicle management system acquires the control command, the control module starts the engine, the engine rotates to drive the generator to generate power, and the generator is used for supplying power to balance electricity. The mode presets preset output power supplied by the generator according to the electric power of electric equipment, for example, a user selects external equipment to be rated with 0.7KW, the preset output power of the generator is 1KW according to the electric power of the external equipment, and the vehicle management system obtains the output power of the generator under the condition that the engine is instructed to drive the generator to supply power.

When the control instruction obtained by the vehicle management system detects a mode of adopting the engine to drive the generator to supply power, the control module starts the engine to drive the generator to supply power, the initial power generation power of the generator can be output power corresponding to a default rotation speed maintained after the engine is started, and the output power in the power supply process of the generator is obtained after external equipment of a user is connected to a vehicle-mounted power supply port. The embodiment obtains the output power in the power supply process of the generator, and reflects the power supply state in real time so as to adjust the power supply state in real time.

In the present embodiment, step 102 obtains the output power of the generator when the control command instructs the generator to be driven by the engine to supply power.

Specifically, step 102 may include:

and step 1021, detecting the output power of the engine in a preset time.

Step 1022 obtains the detected engine output power.

In this embodiment, when a preset time passes during power supply, the output power of the generator is obtained, the preset time can be set to any parameter within 0s to 30s, and during power supply, the output power of the generator is obtained in real time, and the output power is monitored in real time, so that the power supply rotating speed is conveniently adjusted according to the output power, and the system is convenient to manage and adjust the rotating speed.

In this embodiment, before step 103, the method includes:

acquiring the rotation speed of the output power, which corresponds to the power supply of the engine driven generator; and storing the corresponding relation between the output power and the rotating speed of the engine for driving the generator to supply power.

In the present embodiment, the correspondence between the output power and the rotation speed at which the engine-driven generator supplies power can be stored before the rotation speed is adjusted, and when the rotation speed is actually adjusted, the stored correspondence can be used,

the corresponding rotating speed value is directly inquired, so that the actual adjustment operation is convenient.

And step 103, adjusting the rotating speed of the engine for driving the generator to supply power according to the output power.

In this embodiment, when the generator is running at low speed, the output power capability of the generator varies exponentially with the rotational speed, and the output power of the generator at this time increases as the rotational speed of the engine-driven generator increases; when the generator runs beyond the rated rotation speed, the output capacity of the generator reaches the rated output and is not changed with the rotation speed.

The standard of the generator specifies that the rated rotational speed of the vehicle generator is 6000r/min, and in order to pursue the low-speed output capability of the generator, the rated rotational speed of the generator is generally lower than the standard rotational speed in practice. For an automobile engine, the transmission ratio of the engine to the generator is between 2.1 and 2.6, for example, the engine speed is controlled to be 1500r/min, the rotating speed of the generator is about 3150-3900r/min, and the output power of the generator and the rotating speed meet the curve change relation. Therefore, specifically, based on the corresponding relation between the stored output power and the rotating speed of the engine driven generator for power supply, the rotating speed of the power supply is adjusted according to the output power, if the power consumption of a user is very large, the engine maintains a certain rotating speed for continuous power generation, the corresponding rotating speed of the engine is obtained according to the output power, and the power supply rotating speed of the engine driven generator is adjusted to meet the power generation output power requirement.

On one hand, the embodiment stores the corresponding relation between the output power of the generator and the rotating speed of the engine driven generator, and the change of the output power can be realized by utilizing the rotating speed when the output power needs to be regulated; on the other hand, the power supply state can be adjusted by controlling the rotating speed of the engine to drive the power generation, so that the adjustment power supply operation of the vehicle-mounted power supply is simplified, further, the output power can be changed in real time by adjusting the rotating speed, the power supply adjustment efficiency is improved, and the power consumption requirement of a user is met.

In the present embodiment, step 103 adjusts the rotational speed at which the engine drives the generator to supply power according to the output power.

Specifically, step 103 may include:

step 1031, when the output power is smaller than the preset output power, increasing the rotation speed of the engine to drive the generator to supply power to the first rotation speed.

And step 1032, when the output power is greater than the preset output power, reducing the rotation speed of the power supplied by the engine driven generator to the first rotation speed.

It should be noted that, when the output power is equal to the preset output power, the first rotation speed is the rotation speed at which the corresponding engine drives the generator to supply power; in this embodiment, the preset output power may be stored in advance, or may be obtained from an external device. If the preset output power is pre-stored, the parameter may be stored by a user by means of manual entry.

In the specific implementation process, the rotation speed of the engine driven generator is adjusted, when the rotation speed of the actual engine driven generator, which is detected by an engine rotation speed sensor in a vehicle power supply system, is inconsistent with the first rotation speed, the rotation speed of the actual engine driven generator, which is detected by the engine rotation speed sensor, is calculated, the rotation speed deviation between the actual engine driven generator and the first rotation speed is calculated, and when the rotation speed of the engine driven generator is not equal to the first rotation speed, the rotation speed of the engine driven generator is adjusted to be equal to the target first rotation speed.

According to the embodiment, the target preset output power is converted into the preset first rotating speed, namely, the rotating speed of the engine driving generator is adjusted to reach the corresponding first rotating speed, so that the effect that the output power reaches the preset output power is achieved, the visualized control of the output power is facilitated, the power demand of a user is met, further, compared with the operation of adjusting a power supply circuit of a system to adjust the output power, the rotating speed is adjusted, the operation is simplified, and the effect of flexibly adjusting the output power is achieved under the condition that the structure of an original power supply system is not changed.

According to the embodiment of the application, the control command for starting the vehicle-mounted power supply is obtained, the output power of the generator is obtained when the control command indicates that the engine drives the generator to supply power, and the rotating speed of the engine for driving the generator to supply power is adjusted according to the output power. Therefore, the actual power consumption requirement of a user can be based on the rotation speed of the engine driven generator, so that the output power of the generator is matched with the power requirement of the user's electric equipment, and likewise, the user can select the electric equipment matched with the output power to use power according to the output power of the generator during power supply, so that the technical effect that the output power of the vehicle-mounted power supply meets the power requirement of the user is achieved, and the problem that the power cannot be adjusted to discharge outwards in the prior art is solved.

Another embodiment of the present application relates to a vehicle-mounted power supply method, after obtaining a control command for starting vehicle-mounted power supply, as shown in fig. 2, further including:

and 104, acquiring the electric quantity of the storage battery under the condition that the control command indicates to supply power by the storage battery.

In the embodiment, the vehicle battery is the largest electricity storage device on the vehicle, and is mainly used for supplying power to main electric equipment such as a starter, an ignition system and the like when an engine is started; when the engine is not running or running at low speed, power is supplied to various electric equipment; when the electric equipment is too much and the electricity consumption exceeds the power supply capacity of the generator, the storage battery assists the generator to supply power to various electric equipment.

In the embodiment, the battery is used for supplying power in a mode that the battery is used for controlling the battery to supply power after the control command is acquired. The battery management system monitors the electric quantity of the storage battery in the power supply mode so as to reflect the electric quantity state of the storage battery in real time and adjust the power supply mode in time.

And 105, adjusting the rotating speed of the engine driving generator for supplying power to the storage battery according to the electric quantity of the storage battery.

According to the electric quantity of the storage battery obtained by the battery management system, the vehicle-mounted terminal can display the electric quantity of the storage battery, and the electric generator of the vehicle charges the storage battery under constant voltage, so that the rotation speed of the engine driving electric generator is adjusted to supply power to the storage battery, and the output power of the electric generator meets the charging requirement of the storage battery.

The battery management system monitors the battery charge, for example, it takes 20 hours to charge a battery that has been discharged to 10.5V at 60Ah with 3A current. However, in practice, due to the charging loss, the charging current is often 1.5 times of the capacity of the battery to be charged, that is, the product of the charging current and time reaches 90Ah. If the battery is charged for 20 hours, the battery can be fully charged by 4.5A, so that the target charging current can be provided for charging the battery by adjusting the rotating speed of the engine, and the power supply bottle is supplied with power.

The control instruction obtained by the vehicle management system is used for starting the battery to supply power when the battery is detected to supply power, and the battery management system is used for monitoring the electric quantity of the battery.

In this embodiment, battery power supply and engine-driven generator power supply are alternately performed to charge the battery, and when the battery power is lower than a certain set safety threshold, the engine-driven generator is started to charge the battery, and the engine is turned off after the battery is fully charged. The intermittent engine of this mode starts charges to the storage battery, outwards supplies power by the storage battery, and this in-process is adjusted the engine drive the generator is to the rotational speed of storage battery power supply, can improve the efficiency of storage battery charge-discharge.

It should be noted that, in this embodiment, the preset battery power is set according to the actual battery running state, and is used for protecting the battery and preventing the battery performance from being damaged by low electricity, the preset rotation speed value is the rotation speed value of charging the power supply bottle set according to the battery capacity, and the preset battery power may be stored in advance or obtained from the external device. If the preset battery level is pre-stored, the parameter can be stored by a user through a manual input mode.

The voltage of the battery of the vehicle is about 12.5V, and when the voltage of the battery drops by about 10%, the normal power supply working state of the battery is affected; if the voltage drops to about 10.9V, the electric quantity of the storage battery can not work normally. When the electric quantity of the storage battery is completely used up for recharging, the storage battery can be greatly damaged, so that the preset electric quantity of the storage battery is set based on the power parameter of the storage battery of the vehicle, and the purpose of the storage battery is to carry out low-electricity protection on the storage battery.

In step 1052, when the battery is powered, the rotation speed is adjusted to stop the power supply and the battery is started to supply power when the battery is full.

Under the condition that the engine drives the generator to supply power to the storage battery, namely in the storage battery charging process, the battery management system keeps detecting the electric quantity of the storage battery, when the electric quantity of the storage battery shows a full state, the rotating speed of the engine is controlled to be 0r/min, namely in a stop state, and the vehicle management system continues to execute control commands to start the storage battery to supply power.

In this embodiment, the rotation speed that can supply power through adjusting engine drive generator is to the storage battery power supply, for example, to a storage battery that the storage battery capacity is 60Ah and has discharged to the 10.5V of default storage battery electric quantity, need start the generator and charge, when generator output is too low, the time that the storage battery is full of electricity is long, the accessible adjusts the engine rotation speed and makes generator output in satisfying the rated power scope that charges of storage battery, realize the flexibility to the storage battery power supply, when the user is urgent to full of storage battery electric quantity, can be in standard scope, according to generator output, improve storage battery charging speed, improve the efficiency that vehicle-mounted power supply adopted the storage battery power supply.
