Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only a part of the structures related to the present invention, not all of the structures, are shown in the drawings, and furthermore, embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a vehicle energy recovery and distribution method according to an embodiment of the present invention, where the embodiment is applicable to energy recovery during braking of an electric vehicle, and the method may be executed by a vehicle energy recovery and distribution device, and the device may be implemented by software and/or hardware.
As shown in fig. 1, the method specifically includes the following steps:
and step 110, acquiring the recovered electric quantity of the recovered electric energy between the wheels when the vehicle brakes or slides.
The electric energy recovered between the wheels can be understood as electric energy converted from mechanical energy generated by friction of the wheels when the automobile brakes or slides. The recovered electric quantity can be understood as the energy value of the recovered electric energy among the wheels.
Specifically, in the driving process of the vehicle, when a driver steps on a brake pedal or the vehicle is in a sliding state, the vehicle brake can convert redundant mechanical energy into electric energy, the recovered electric quantity of the recovered electric energy among the wheels generated in a preset time period can be obtained, and analysis is performed according to the value of the recovered electric quantity so as to reasonably distribute the recovered electric energy among the wheels.
And 120, if the current environment temperature is lower than the preset temperature, adjusting the target temperature of the warm air loop according to the recovered electric quantity, so that the inter-wheel recovered electric energy is used for improving the water temperature of the warm air loop.
When the vehicle runs, the normal running of the vehicle is possibly influenced by the high or low water temperature of the warm air loop, and even potential safety hazards exist, so that the water temperature of the warm air loop needs to be controlled within a reasonable range, and the target temperature of the warm air loop can be understood as the target temperature to be reached by controlling liquid in the warm air loop. For example, if the target temperature of the warm air circuit is 50 ℃ and the current warm air circuit water temperature is only 30 ℃, then the warm air circuit water temperature needs to be increased to be as close to 50 ℃ as possible.
Specifically, a reasonable preset temperature may be preset, for example, 10 ℃, and when the current ambient temperature is lower than the preset temperature, it indicates that the ambient temperature is too low, and the driver generally selects to start the air conditioner to heat. The air conditioner consumes the electric energy of the power battery, the electric quantity output of the power battery for heating needs to be limited on the premise of ensuring that the driving mileage of the vehicle is not greatly attenuated, and the efficiency of refrigerating the power battery can be reduced by manual forced use of the air conditioner at the moment. Therefore, the target temperature of the warm air loop can be dynamically adjusted according to the recovered electric quantity, and the electric energy recovered among the wheels is used for improving the water temperature of the warm air loop. The water temperature of the warm air loop is increased, so that the warm air loop can be directly used for heating an air conditioner, and the refrigeration of a passenger compartment of a vehicle by discharging power batteries is reduced.
According to the technical scheme, when the vehicle brakes or slides, the recovery electric quantity of the electric energy recovered between the wheels is obtained, and if the current environment temperature is lower than the preset temperature, the target temperature of the warm air loop is adjusted according to the recovery electric quantity, so that the electric energy recovered between the wheels is used for improving the water temperature of the warm air loop. The invention solves the problems that the energy form is converted for multiple times and the energy recovery utilization rate is low in the process of converting mechanical energy into electric energy, converting electric energy into chemical energy and converting chemical energy into electric energy in the conventional vehicle braking energy recovery, realizes that the vehicle braking recovery energy is directly used for heating, enables the recovered energy to be directly converted into heat in a specific scene, and reduces the energy conversion loss.
Example two
Fig. 2 is a flowchart of a vehicle energy recovery and distribution method according to a second embodiment of the present invention. The embodiment further optimizes the vehicle energy recovery and distribution method on the basis of the embodiment.
As shown in fig. 2, the method specifically includes:
and step 210, acquiring the recovered electric quantity of the recovered electric energy between the wheels when the vehicle brakes or slides.
Specifically, in the driving process of the vehicle, when a driver steps on a brake pedal or the vehicle is in a sliding state, the vehicle brake can convert redundant mechanical energy into electric energy, the recovered electric quantity of the recovered electric energy among the wheels generated in a preset time period can be obtained, and analysis is performed according to the value of the recovered electric quantity so as to reasonably distribute the recovered electric energy among the wheels.
Step 220, judging whether the current environment temperature is less than a preset temperature.
Specifically, the current ambient temperature may be obtained, and it is determined whether the current ambient temperature is less than a preset temperature value, if so, step 240 is performed; otherwise, step 230 is performed.
Step 230, charging the battery by using the electric energy recovered between the wheels.
Specifically, if the current ambient temperature is not lower than the preset temperature, the current ambient temperature is considered to be ideal, and the vehicle does not consume too much battery energy due to heating, so that the electric energy recovered between the wheels can be directly stored in the power battery, namely, the battery is charged.
And 240, determining a target temperature adjustment value according to the recovered electric quantity.
The target temperature adjustment value may be a fluctuation value for adjusting the current target temperature of the warm air circuit.
Specifically, real-time vehicle testing can be performed in advance, different vehicle types are calibrated respectively, a relational mapping table of the recovered electric quantity and the target temperature adjustment value is obtained, and in the actual use process, the corresponding target temperature adjustment value can be obtained by looking up the table according to the obtained recovered electric quantity.
And step 250, acquiring the target temperature of the current loop, and determining the adjusted target temperature of the loop according to the target temperature of the current loop and the target temperature adjustment value.
And the current loop target temperature is the target temperature of the warm air loop set at the current moment.
Specifically, the target temperature of the warm air loop set at the current time may be obtained, and the target temperature adjustment value determined in step 240 is added to the current loop target temperature to obtain the adjusted loop target temperature, that is, the target temperature of the warm air loop is temporarily increased, so as to achieve the purpose of making the inter-wheel recovered electric energy directly used for heating the vehicle as much as possible.
And step 260, judging whether the adjusted loop target temperature is greater than the maximum target temperature.
The value range of the target temperature of the warm air loop should be within a reasonable target temperature range, that is, the target temperature of the warm air loop needs to be within a reasonable range and cannot be set to be too high or too low, and the maximum target temperature can be understood as the maximum temperature value within the target temperature range.
Specifically, a preset maximum target temperature is obtained, whether the adjusted loop target temperature is greater than the maximum target temperature is judged, and if yes, the step 280 is performed; otherwise, step 270 is performed.
And 270, recovering electric energy among all the wheels to improve the water temperature of the warm air loop.
Specifically, if the target temperature of the battery after adjustment is within the target temperature range and is not higher than the maximum target temperature, the problem of vehicle damage or energy waste cannot be caused even if the inter-wheel recovered electric energy is completely used for increasing the water temperature of the warm air loop, and therefore the water temperature of the warm air loop can be increased by the all inter-wheel recovered electric energy.
And step 280, determining actual temperature adjusting electric quantity according to the maximum target temperature, and using the inter-wheel recovered electric energy corresponding to the actual temperature adjusting electric quantity for improving the water temperature of the warm air loop.
Specifically, if the target temperature of the adjusted loop is greater than the maximum target temperature, that is, the target temperature of the adjusted loop is not within the target temperature range, then the problem that the vehicle is damaged or energy is wasted due to the fact that all the electric energy recovered between the wheels is used for increasing the water temperature of the warm air loop may be caused, and therefore part of the electric energy recovered between the wheels can be used for increasing the water temperature of the warm air loop. At this time, the maximum target temperature can be determined as a new target temperature of the warm air loop, the difference between the current loop target temperature and the new warm air loop target temperature can be used as an actual target temperature adjustment value, and the actual temperature adjustment electric quantity can be determined according to the actual target temperature adjustment value. And recycling electric energy among the wheels with the energy value being the actual temperature-adjusting electric quantity to improve the water temperature of the warm air loop.
And 290, determining the difference value between the recovered electric quantity and the actual temperature-adjusting electric quantity as the generated electric quantity, and charging the battery by using the inter-wheel recovered electric energy corresponding to the generated electric quantity.
Specifically, when the electric energy recovered among the wheels is large, a part of the electric energy recovered among the wheels is used for improving the water temperature of the warm air loop, and then the rest of the electric energy recovered among the wheels can be stored in the power battery. The recovered electric quantity can be subtracted by the actual temperature-adjusting electric quantity to obtain the generated electric quantity, and the electric energy is recovered between the wheels of the generated electric quantity by the energy value and is used for charging the battery.
For example, fig. 3 is a schematic diagram of a vehicle energy recovery distribution method according to a second embodiment of the present invention. When the vehicle brakes or slides, the vehicle control unit sends an instruction to the motor controller to recover and generate power with corresponding strength, so that the recovered electric energy between the wheels is obtained. The preset temperature may be set to T1 in advance, and if the current ambient temperature is greater than the preset temperature T1, the vehicle controller sends an instruction to the motor controller and the battery controller to charge the electric battery using the electric power recovered between the wheels. If the current environment temperature is lower than T1, the vehicle control unit sends a heating instruction to the PTC/compressor in combination with the recovered electric quantity, and stores the energy recovered in real time into hot water for distribution to air conditioner heating or power battery heating, so that the proportion of charging into the battery is reduced. The mode of the compressor/PTC load of the air conditioning system is indirectly adjusted by adjusting the target water temperature, so that the compressor/PTC works in a peak staggering way, the energy conversion times are reduced, and the energy is saved.
According to the technical scheme of the embodiment, when the vehicle brakes or slides, the recovered electric quantity of the electric energy recovered among the wheels is obtained, and if the current environment temperature is greater than or equal to the preset temperature, the battery is charged by utilizing the electric energy recovered among the wheels; if the current environment temperature is lower than the preset temperature, the target temperature of the warm air loop is adjusted according to the recovered electric quantity, the electric energy recovered between the wheels is used for improving the water temperature of the warm air loop, the target temperature of the warm air loop is guaranteed to be within a reasonable temperature range, when the electric energy recovered between the wheels is more, a part of electric energy recovered between the wheels can be used for improving the water temperature of the warm air loop, and the electric energy recovered between the other wheels is transferred to a power battery. The invention solves the problems that the energy form is converted for multiple times and the energy recovery utilization rate is low in the process of converting mechanical energy into electric energy, converting electric energy into chemical energy and converting chemical energy into electric energy in the conventional vehicle braking energy recovery, realizes that the vehicle braking recovery energy is directly used for heating, enables the recovered energy to be directly converted into heat in a specific scene, and reduces the energy conversion loss.
