With the continuous development of society, automobiles enter into thousands of households, and with the diversification of daily life demands of people, the types of automobiles are various, for example, a motor home, also called as "home on wheels", has two functions of "home" and "car", can move and is equipped with necessary infrastructure for home, and the motor home is more and more favored by people due to the unique performance characteristics of the motor home.
However, as the motor home is equipped with a large number of electric appliances, the demand for electricity is large, and the power supply power is also greatly tested.
Among the prior art, car as a house power supply system is mostly by generator and battery constitution, after being the consumer power supply on the car through fixed power by the generator, when consumer load power on the car as a house is great, the generating power of generator is not enough, in order to guarantee the normal permission of consumer, supplies power for the consumer through the battery simultaneously, however, long-time passing through the battery supplies power to the consumer, very easily causes the battery feed to lead to unable the start-up.
The following will describe in detail how to avoid the problem of battery feeding during the distribution of power to a vehicle, with reference to specific embodiments and the accompanying drawings.
Example one
Referring to fig. 1, a power distribution method for a vehicle according to a first embodiment of the present invention includes steps S10-S14.
And step S10, controlling the storage battery sensor to monitor the current residual capacity of the storage battery in real time.
The battery sensor calculates the battery capacity of the storage battery by monitoring the voltage, the current and the temperature of the storage battery, the battery capacity signal provided by monitoring the voltage, the current and the temperature of the storage battery is more accurate and intelligent, and the problem that the read capacity value is inconsistent with the actual capacity value of the storage battery due to the fact that the capacity value is directly read by a battery management system under the conditions of aging of the storage battery and the change of the ambient temperature is solved.
Step S11, determining whether the current remaining power is lower than a preset power threshold; if yes, go to step S12.
Whether the electric quantity of the storage battery is consumed or not, namely whether the risk of power feeding exists or not can be known by judging whether the current residual electric quantity is lower than a preset electric quantity threshold value or not.
And step S12, acquiring a corresponding engine gain rotating speed according to the acquired current residual capacity.
Specifically, in practice, a part of the rotation speed of the engine is used for driving the vehicle, and another part of the rotation speed of the engine is stored for generating power of the generator, wherein the engine gain rotation speed represents the rotation speed of the engine increased on the basis of the original rotation speed, and more specifically, after the current remaining capacity of the battery is obtained, the corresponding engine gain rotation speed can be obtained from a preset mapping table, it can be understood that, in the power utilization process of the vehicle, the generator mainly provides power supply, and the power generation power of the generator is in direct proportion to the rotation speed of the engine, when the rotation speed of the engine is higher, generally, the power generation power of the generator is higher, and the reason why the power of the battery is lower than the preset power threshold is mainly that the current load power of the vehicle is higher, and the power generation power of the generator cannot meet the power utilization requirement of the vehicle, in order to ensure the normal use of the electrical equipment of the vehicle, the storage battery consumes part of electric energy to supply power to electric equipment of the vehicle, so that the electric quantity of the storage battery is exhausted, and therefore, in order to avoid feeding caused by excessive power consumption of the storage battery, the generated power of the generator needs to be improved, wherein the preset mapping table can be established through multiple times of experimental verification, for example, when the electric quantity of the storage battery is within a certain range, the value of the gain rotating speed of the engine can be ensured to be supplied to the electric equipment on the vehicle by the generator.
And step S13, sending a gain instruction to the engine according to the gain rotating speed of the engine, and controlling the generator to generate power according to the gain instruction.
The power generation power of the generator is improved by improving the rotating speed of the engine, and specifically, the power generation power CAN be in communication connection with an engine management system of a vehicle chassis through a CAN (controller area network) in a vehicle so that the rotating speed of the engine is improved.
And step S14, distributing the generated power generated by the generator to a vehicle load electrical appliance to supply power to the vehicle load electrical appliance.
Specifically, the generated power of the generator is ensured to meet the normal supply of the vehicle load electrical appliances through the increased generated power of the generator.
In summary, in the embodiment of the present invention, the current generated power of the vehicle generator is known to be lower than the load power of the vehicle electrical equipment by monitoring the electric quantity of the storage battery, and the generated power of the generator is increased by increasing the engine speed, so that the generated power of the generator ensures the normal supply of the electrical equipment, and the problem of power feeding caused by excessive consumption of the storage battery is avoided.
Example two
Referring to fig. 2, a power distribution method for a vehicle according to a second embodiment of the present invention includes steps S20-S26.
And step S20, controlling the storage battery sensor to monitor the current residual capacity of the storage battery in real time.
Step S21, determining whether the current remaining power is lower than a preset power threshold; if yes, go to step S22.
And step S22, acquiring a corresponding engine gain rotating speed according to the acquired current residual capacity.
Step S23, sending a gain instruction to the engine according to the gain rotating speed of the engine, and controlling the generator to generate power according to the gain instruction;
and step S24, distributing the generated power generated by the generator to a vehicle load electrical appliance to supply power to the vehicle load electrical appliance.
Step S25, acquiring the load power of the vehicle load electrical appliance, and judging whether the generated power generated by the generator is higher than the load power; if yes, go to step S26.
When the power consumption equipment of the vehicle is in use, the load power of the vehicle load electrical appliance can be dynamically changed, in order to ensure that the power generation power of the generator meets the power consumption requirement of the vehicle load electrical appliance as far as possible, under the condition of meeting the power generation condition, the value of the gain rotating speed can be set based on the total load power condition of the vehicle load electrical appliance, in the actual condition, the vehicle load electrical appliance can not be used all the time, when part of the load electrical appliance is not used at a certain moment, the power generation power of the generator can be higher than the load power of the current vehicle load electrical appliance, at the moment, the excessive power generation power can be used for compensating the electric quantity of the storage battery, so that the electric quantity of the storage battery is ensured to be in a relatively healthy state.
Step S26, the generated power generated by the generator is distributed to the battery and the vehicle load electrical appliance, respectively.
Further, in some alternative embodiments of the present invention, for safety of battery charge compensation, the step of distributing the generated power generated by the generator to the battery and the vehicle load electrical appliance respectively comprises:
and when the storage battery meets the preset condition of stopping electric quantity distribution, controlling the generator to stop distributing the electric quantity to the storage battery.
The preset condition for stopping the power distribution includes that the battery power compensation reaches a threshold (such as 90%, 95%, 98% … …), or the battery power compensation time reaches a threshold (such as 6h, 8h, 12h … …).
In addition, during the power generation process of the generator, the generated power of the generator with the increased rotation speed may be lower than the load power of the vehicle-mounted load electrical appliance due to some factors. For example, the conversion efficiency of the generator is low due to a fault or the generated power of the generator suddenly drops in a certain period of time, so that the battery needs to continue to supply power to the vehicle load electrical appliances, which may result in the battery feeding.
In view of the above, in some optional embodiments of the present invention, the step of distributing the generated power generated by the generator to the vehicle load electrical appliances to supply power to the vehicle load electrical appliances further includes:
judging whether the generated power generated by the generator is higher than the load power;
if not, acquiring the current residual electric quantity of the storage battery, and judging whether the current residual electric quantity is lower than the preset electric quantity threshold value;
if yes, distributing the generated power generated by the generator to the storage battery and the vehicle load electrical appliance respectively
Judging whether the current residual electric quantity of the storage battery is higher than the preset electric quantity threshold value or not in the process of charging the storage battery;
and if so, distributing the generated power generated by the generator to vehicle load electric appliances.
When judging that the current residual capacity of battery is higher than predetermined electric quantity threshold value, there is not the danger of feed current battery, need not carry out the electric quantity to the battery this moment, and when judging that the current residual capacity of battery is less than predetermined electric quantity threshold value, need carry out the electric quantity to the battery and supply in order to avoid the battery feed this moment.
When the current residual capacity of the storage battery is judged to be lower than the preset capacity threshold value, the generated power generated by the generator is distributed to the storage battery, so that the use of the load electric appliance is temporarily reduced, and less generated power is distributed to the load electric appliance, so that the storage battery is prevented from feeding due to the consumption of the electric quantity of the storage battery.
Furthermore, in the charging process of the storage battery, whether the current residual electric quantity of the storage battery is higher than a preset electric quantity threshold value or not is judged, and when the current residual electric quantity of the storage battery is higher than the preset electric quantity threshold value, the generated power generated by the generator is uniformly distributed to the vehicle load electric appliances so as to ensure the normal operation of the load electric appliances.
In summary, in the embodiment of the present invention, the current generated power of the vehicle generator is known to be lower than the load power of the vehicle electrical equipment by monitoring the electric quantity of the storage battery, and the generated power of the generator is increased by increasing the engine speed, so that the generated power of the generator ensures the normal supply of the electrical equipment, and when the generated power of the generator after gain is low, the storage battery with low electric quantity is preferentially charged, thereby avoiding the problem of power feeding caused by excessive consumption of the storage battery.
EXAMPLE III
Referring to fig. 3, a power distribution method for a vehicle according to a third embodiment of the present invention includes steps S30-S35.
And step S30, controlling the storage battery sensor to monitor the current residual capacity of the storage battery in real time.
Step S31, determining whether the current remaining power is lower than a preset power threshold; if yes, go to step S32.
And step S32, acquiring a corresponding engine gain rotating speed according to the acquired current residual capacity.
Step S33, sending a gain instruction to the engine according to the gain rotating speed of the engine, and controlling the generator to generate power according to the gain instruction;
and step S34, distributing the generated power generated by the generator to a vehicle load electrical appliance to supply power to the vehicle load electrical appliance.
And step S35, displaying the current residual capacity of the storage battery, the current voltage of the storage battery, the sustainable time of the storage battery and the load power of the current vehicle load electric appliance through the vehicle-mounted display system.
The current residual capacity of the storage battery, the current voltage of the storage battery, the sustainable time of the storage battery and the load power of a current vehicle load electrical appliance are displayed through the vehicle-mounted display system, so that a user can visually know the power distribution information in the power distribution system of the current vehicle.
To sum up, according to the embodiment of the invention, the current generated power of the vehicle generator is known to be lower than the load power of the vehicle electric equipment by monitoring the electric quantity of the storage battery, the generated power of the generator is improved by increasing the rotating speed of the engine, so that the generated power of the generator guarantees the normal supply of the electric equipment, and the power distribution information is displayed by the vehicle-mounted display system, so that the power distribution state of the current vehicle-mounted power distribution system can be known more intuitively by a user while the power feed caused by excessive consumption of the storage battery is avoided.
