The power supply of pure electric motor home is mainly applied to this embodiment, provides whole power for the car as a house through water hydrogen power generation technique, and energy saving and emission reduction and high efficiency are separated the driving power consumption power supply battery and the life power consumption power supply battery of car as a house simultaneously, avoid phenomenons such as the voltage fluctuation that consequently takes place, signal interference, reduced power supply battery's capacity requirement, still carry out electric power regulation through the power generation facility to the car as a house to satisfy and better adapt to the power consumption demand of car as a house.
As shown in fig. 1, the caravan provided in this embodiment mainly includes: the device comprises a fuel cell assembly, a power cell assembly, an electrical appliance battery assembly and a power regulating module. The motor home in this embodiment is a pure electric motor home, and only depends on the electric energy generated by the water-hydrogen power generation technology as power, and the electric energy generated by each electric device provided by the motor home and externally provided by the motor home is mainly used as a power supply.
A fuel cell module is used for generating electric power by an electrochemical reaction using a hydrogen raw material (e.g., high-purity hydrogen) and is a power generation device for a motor home. The fuel cell assembly can include polylith hydrogen fuel cell to satisfy the power consumption demand of car as a house, the maximum power consumption demand setting of car as a house that the quantity of hydrogen fuel cell also can be based on.
The power battery component is electrically connected with the fuel battery component and is used for storing a part of electric energy generated by the fuel battery component and supplying power to the electric equipment for driving of the motor home by utilizing the stored electric energy. The power battery component is a device of the motor home and is a power supply (storage battery) for providing a power source for the motor home, and in the electric energy generated by the electrochemical reaction of the fuel battery component, a part of the electric energy is stored in the power battery component to provide electric power for driving electric equipment of the motor home, for example, the electric power is supplied to the motor, and the motor further drives the power transmission system to operate, so that the motor home can run. The electric equipment for driving mainly refers to equipment which is arranged on a vehicle body and is related to the driving of a motor home, and comprises a motor, a wiper, a washer, a cab air conditioner and the like. The power battery assembly can comprise a plurality of power batteries so as to meet the requirement of driving the limo for electricity storage capacity. The power battery can be a lithium storage battery.
The electric appliance battery component is also electrically connected with the fuel battery component and is used for storing the other part of electric energy generated by the fuel battery component and supplying power to the domestic electric appliance of the motor home by utilizing the stored electric energy. One part of electric energy generated by the fuel cell component is stored in the power cell component, and the other part of electric energy is stored in the electric appliance battery component to provide electric power for the domestic electric appliances of the motor home so as to realize the habitability of the motor home. The household electrical appliance mainly refers to equipment which is installed indoors and is related to human living life, and comprises a computer, a refrigerator, an air conditioner, a television, a washing machine, a microwave oven, a sound device and the like. The electrical appliance battery component can comprise a plurality of electrical appliance batteries so as to meet the requirement of life on the electricity storage capacity in the motor home. The electric appliance battery can also be a lithium storage battery.
It can be understood that the electric appliance battery assembly is connected with an inverter, and direct current in the electric appliance battery is converted into alternating current through the inverter so as to supply power to domestic electric appliances.
The power adjusting module is simultaneously electrically connected with the fuel cell assembly, the power cell assembly and the electrical appliance battery assembly and is used for monitoring the power utilization level of the power cell assembly and the electrical appliance battery assembly, adjusting the operating power of the fuel cell assembly according to the power utilization level of the power cell assembly and the electrical appliance battery assembly and adjusting the power output by the fuel cell assembly to the power cell assembly and the electrical appliance battery assembly respectively.
When the motor home is used, the motor home needs to obtain power for driving and power for maintaining power supply of indoor electric appliances, so that the fuel cell assembly can simultaneously supply power to the power cell assembly and the electric appliance battery assembly under the normal condition to ensure that the motor home has enough backup power for driving and the indoor electric appliances also have enough backup power for executing respective functions. However, in the process of using the caravan, the power consumption of the power system of the caravan and the power consumption of the electrical appliances in different periods of time both change to some extent, for example, when the caravan is running at a high speed and is running at a low speed, the output power of the power battery assembly is different, the start and stop of high-power electrical appliances such as an air conditioner and a microwave oven in the caravan chamber can also cause the output power of the electrical appliance battery assembly to be different, and the change of the output power of the two battery assemblies may cause insufficient power supply (the residual power of the power battery assembly and the electrical appliance battery assembly is low) or excessive power supply (the power battery assembly and the electrical appliance battery assembly are full), so the power regulating module is arranged to monitor the power consumption level of the power battery assembly and.
If the power utilization level of the power battery assembly is maintained at a higher level than the original level within a certain time, for example, the output power is continuously higher because the motor home is changed from low-speed running to high-speed running, and the output power of the power utilization battery assembly is basically unchanged, the operating power of the fuel battery assembly needs to be increased at the moment to increase the output power of the fuel battery assembly, and meanwhile, the output power of the fuel battery assembly to the power battery assembly is increased to enable the input power of the power battery assembly to be approximately the same as the output power, so that the power utilization requirement of the motor home for high-speed running is met.
If the power consumption level of the power battery component changes less within a certain time, and the output power of the electrical appliance battery component is suddenly reduced, for example, the indoor power consumption level is reduced by turning off high-power electrical appliances such as an air conditioner and a microwave oven, the operating power of the fuel battery component needs to be reduced at the moment so as to reduce the output power of the fuel battery component, and meanwhile, the output power of the fuel battery component to the electrical appliance battery component is reduced so as to enable the input power of the electrical appliance battery component to be approximately the same as the output power, so that the electrical appliance battery component is prevented from being in a full charge state for a long time.
If the power consumption levels of the power battery component and the electrical appliance battery component are obviously changed in the same time period, the adjusting direction (increasing or decreasing) of the operating power of the fuel battery component can be determined according to the comprehensive changing conditions of the power battery component and the electrical appliance battery component. It can be understood that, since the capacity and the rated power of the power battery assembly are different from those of the indoor electric appliances, when the electric power changes of the two are considered together to obtain the final regulation direction, the higher of the capacity and the rated power is taken as the main consideration.
It should be noted that the period for monitoring the battery assembly can be determined according to the capacity and rated power of the battery assembly, if no high-power electrical appliance exists indoors, the capacity and rated power of the power battery assembly are both greater than the capacity and rated power of the electrical appliance battery assembly, and the monitoring frequency of the power consumption level of the power battery assembly is higher than that of the electrical appliance battery assembly; if there are more indoor high-power electric appliances, the capacity and the rated power of the power battery assembly may be both smaller than those of the electric appliance battery assembly, and the monitoring frequency of the power consumption level of the power battery assembly is about the same as that of the electric appliance battery assembly.
In one embodiment, the power conditioning module mainly includes: the device comprises a first monitoring unit, a first prediction unit and a first regulation unit. The first monitoring unit is used for monitoring the output power of the power battery assembly and/or is used for monitoring the speed and the acceleration of the motor home. The first prediction unit is used for predicting the power utilization trend of the power battery component according to the data measured by the first monitoring unit within a certain time in the past. The first adjusting unit is used for adjusting the operation power of the fuel cell assembly to the direction same as the development direction of the power utilization trend according to the power utilization trend of the power cell assembly predicted by the first predicting unit, and adjusting the power output from the fuel cell assembly to the power cell assembly.
The first monitoring unit is responsible for regularly monitoring the power utilization level of the power battery assembly, and when the power utilization level of the power battery assembly is monitored, the first monitoring unit can monitor the power battery assembly in a direct acquisition mode, namely monitoring the output power of the power battery assembly, and acquiring the change of the output power to obtain the power utilization level; the method can also be realized by indirect inference, namely monitoring the running speed and acceleration of the motor home, if the speed and the acceleration are relatively constant, the output power is basically unchanged, and if the speed and the acceleration are both increased, the speed of the motor home is increased, and the power level of the motor home is inevitably increased, so that the increase and the approximate increase of the output power of the power battery component are inferred. It can be understood that the first monitoring unit can monitor the power utilization level of the power battery assembly in the direct and indirect manners, and can perform troubleshooting in time when the conclusions of the two manners are different or even opposite.
The first prediction unit predicts the power utilization trend of the power battery component according to monitoring data in a set time period in data obtained by past monitoring of the first monitoring unit, for example, the monitoring cycle of the first prediction unit is T, the current time is Tn, namely the nth monitoring completion time, and at the moment, the first prediction unit predicts the power utilization trend according to m +1 times of monitoring data between Tn-m and Tn. If the output power of the power battery assembly is increased to some extent, or the speed of the motor home is continuously increased and the acceleration is unchanged, predicting that the electricity utilization trend is an increasing trend; if the output power of the power battery assembly is reduced to some extent, or the speed of the motor home is continuously reduced while the acceleration is unchanged, the electricity utilization trend can be predicted to be a descending trend; if the output power of the power battery assembly is basically unchanged, or the speed of the motor home is continuously kept and the acceleration is basically unchanged, the electricity utilization trend can be predicted to be a flat trend.
After the power utilization trend is predicted, the first adjusting unit adjusts the output power of the fuel cell assembly and the power output by the fuel cell assembly to the power cell assembly according to the power utilization trend. If the electricity utilization trend is predicted to be an ascending trend, the operating power of the fuel cell assembly is increased, and the power output from the fuel cell assembly to the power cell assembly is increased, so that the reduction range of the residual electricity quantity of the power cell assembly is reduced as small as possible on the premise that the motor home runs in an accelerated mode, and the same principle is used when the electricity utilization trend is predicted to be a descending trend. If the predicted power utilization trend is a flat trend, the operation power of the fuel cell assembly and the power output by the fuel cell assembly to the power cell assembly do not need to be adjusted.
In order to adjust the fuel cell assembly more accurately, the first prediction unit is further used for predicting the power consumption change amplitude of the power cell assembly, and the first adjusting unit is further used for adjusting the operation power of the fuel cell assembly and the power output by the fuel cell assembly to the power cell assembly according to the power consumption change amplitude predicted by the first prediction unit. Through predicting the specific electricity utilization change amplitude, the electric quantity of the power battery assembly can be kept constant as much as possible on the premise of meeting the requirement of accelerating or decelerating driving of the motor home, and the reduction of the residual electric quantity of the power battery assembly caused by the driving speed change of the motor home is eliminated to the greatest extent.
In one embodiment, the power conditioning module further includes: the device comprises a second monitoring unit, a second prediction unit and a second regulation unit. The second monitoring unit is used for monitoring the output power of the electric appliance battery pack. The second prediction unit is used for predicting the power utilization trend of the electric appliance battery pack according to data measured by the second monitoring unit within a certain time in the past. The second adjusting unit is used for adjusting the operation power of the fuel cell assembly to the direction same as the development direction of the power utilization trend according to the power utilization trend of the electrical appliance battery assembly predicted by the second predicting unit, and adjusting the power output from the fuel cell assembly to the electrical appliance battery assembly.
The second monitoring unit is responsible for regularly monitoring the power consumption level with electrical apparatus battery pack, and when monitoring the power consumption level with electrical apparatus battery pack, the second monitoring unit is usually realized through the mode that directly acquires with electrical apparatus battery pack's monitoring, monitors promptly with electrical apparatus battery pack's output, learns the power consumption level through the change that acquires output.
The second prediction unit predicts the power utilization trend of the electrical equipment battery assembly according to the monitoring data in a set time period in the data obtained by the previous monitoring of the second monitoring unit, for example, the monitoring period of the second prediction unit is t, the current time is tn, namely the nth monitoring completion time, and at the moment, the second prediction unit predicts the power utilization trend according to m +1 times of monitoring data between tn-m and tn. If the output power of the electric appliance battery assembly is increased (for example, a high-power electric appliance is started in a motor home), the electricity utilization trend can be predicted to be an increasing trend; if the output power of the electric appliance battery assembly is reduced (for example, a high-power electric appliance is turned off in a motor home), the electricity utilization trend can be predicted to be a descending trend; if the output power of the electric appliance battery pack is basically unchanged (for example, any electric appliance is not started or stopped in a motor home), the electricity utilization trend can be predicted to be a flat trend.
After the power utilization trend is predicted, the second adjusting unit adjusts the output power of the fuel cell assembly and the power output by the fuel cell assembly to the power utilization battery assembly according to the power utilization trend. If the electricity utilization trend is predicted to be an ascending trend, the operating power of the fuel cell assembly is increased, and the power output from the fuel cell assembly to the electricity utilization device battery assembly is increased, so that the electric quantity of the electricity utilization device battery assembly is kept constant as much as possible on the premise that the accelerated running of the motor home is met. The same principle is used when the electricity utilization trend is predicted to be a descending trend. If the predicted power utilization trend is a flat trend, the operation power of the fuel cell assembly and the power output by the fuel cell assembly to the power utilization battery assembly do not need to be adjusted.
In order to more accurately adjust the fuel cell assembly, the second prediction unit is further used for predicting the power consumption change amplitude of the electrical appliance battery assembly, and the second adjusting unit is further used for adjusting the operation power of the fuel cell assembly and the power output by the fuel cell assembly to the electrical appliance battery assembly according to the power consumption change amplitude predicted by the second prediction unit. Through predicting the specific power consumption change amplitude, the electric quantity of the electric appliance battery assembly can be kept constant as much as possible on the premise of meeting the requirement of starting and stopping a high-power electric appliance of a motor home, and the reduction of the residual electric quantity of the electric appliance battery assembly caused by the power change of the indoor total electric appliance of the motor home is eliminated to the greatest extent.
It should be noted that, if it is predicted that the power consumption trends of the power battery assembly and the electrical appliance battery assembly are both in an increasing trend or in a decreasing trend, the output power of the power battery assembly and the electrical appliance battery assembly needs to be increased to a level that can satisfy the output power of the power battery assembly and the electrical appliance battery assembly at the same time when the operating power of the fuel battery assembly is adjusted.
If the predicted power utilization trends of the power battery assembly and the electrical appliance battery assembly are that one of the power battery assembly and the electrical appliance battery assembly is an ascending trend and the other is a descending trend, the predicted power utilization change amplitude of the power battery assembly and the electrical appliance battery assembly can be comprehensively considered to determine whether the fuel battery assembly is finally used for increasing the operating power or reducing the operating power.
