Description

Technical Field

[0001] The present invention belongs to the field of electric vehicles, and relates to a carbon emission calculation method and system for electric vehicles with dual functions of transportation and energy storage. Background Art

[0002] As the demand for electric vehicles continues to grow in the global market, electric vehicle exports have become an important force in promoting national economic and technological development. However, as countries pay more and more attention to environmental protection and carbon emissions, the carbon emissions of electric vehicles have gradually become the focus of global attention. Traditionally, electric vehicles are more environmentally friendly than fuel vehicles, but the carbon emissions generated during their manufacturing, use and recycling need to be fully evaluated to ensure their true environmental benefits.

[0003] Existing algorithms and equipment often only consider the traffic attributes of electric vehicles, but ignore the energy storage attributes (carbon reduction potential) of electric vehicles during use, and therefore often overestimate the carbon emissions of electric vehicles during their life cycle. The functional units used in the existing calculation methods for the energy storage attributes of electric vehicles are inconsistent with the functional units used for traffic attributes, and the two cannot be directly integrated. If only a simple integration process is performed, it is very easy to cause repeated calculations.

[0004] The existing calculation boundary of electric vehicle life cycle carbon emissions is incomplete: Defining functional units is the premise for determining the calculation boundary of electric vehicle life cycle carbon emissions and sorting out its carbon emission sources. The existing electric vehicle life cycle carbon emissions calculation method only considers one function of the electric vehicle when defining functional units, that is, only considering the transportation function, and the functional unit is defined as carbon emissions per kilometer of driving, or the energy storage function, and the functional unit is defined as carbon emissions per kW of energy storage. This calculation method is also consistent with the life cycle carbon emissions calculation of most products. However, electric vehicles are different from traditional fuel vehicles and have the dual characteristics of transportation and energy storage. Therefore, considering only one function will cause the calculation boundary of electric vehicle life cycle carbon emissions to be incomplete, that is, "missing calculation", resulting in inaccurate calculation results.

[0005] It is difficult to directly integrate the carbon emissions related to the transportation and energy storage functions of electric vehicles: As mentioned earlier, when only the transportation function of electric vehicles is considered, the functional unit is often defined as the total carbon emissions per kilometer of travel, and when the transportation function is considered, its functional unit is often defined as the total carbon emissions per kW of energy storage. The units are different and cannot be directly added, resulting in poor accuracy in the calculated carbon emissions per unit of transportation function of electric vehicles. How to achieve the mutual integration of different units is the current technical difficulty in realizing the complete calculation of the life cycle of electric vehicles. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a carbon emission calculation method and system for electric vehicles with dual functions of transportation and energy storage.

[0063] Embodiment 1

[0064] refer to Figure 1 and Figure 2 The carbon emission calculation method for the dual functions of electric vehicles, transportation and energy storage according to the present invention comprises the following steps:

[0065] 1) Determine the type of electric vehicle charging scenario;

[0066] It should be noted that the present invention analyzes the carbon emission calculation of the electric vehicle life cycle starting from analyzing the types of electric vehicle charging scenarios. The types of electric vehicle charging scenarios include disordered charging scenarios, orderly charging scenarios and V2G energy storage scenarios.

[0067] 2) Calculate the carbon emissions of electric vehicles per unit of transportation function unit based on the type of electric vehicle charging scenario.

[0068] The specific operations of step 2) are:

[0069] a) When the electric vehicle charging scenario is a disorderly charging scenario, the process of calculating the carbon emissions per unit of traffic function unit of the electric vehicle is:

[0070] In the disorderly charging scenario, electric vehicle charging will cause additional electricity demand, increase the power generation of the power grid, and cause carbon emissions from upstream power production of electric vehicles, which is equivalent to considering the carbon emissions of upstream power production process in the use phase of electric vehicle transportation function modeling. The result is equal to the carbon emissions of electric vehicles under general transportation functions, that is:

[0071] E t1 =E p +E u +E e =E t1,t ×L

[0072] Among them, E t1 is the total carbon emissions under disorderly charging scenario (t), E p is the carbon emissions from the production of raw materials and product assembly of electric vehicles (t), E u is the carbon emissions of electric vehicles during use (t), E e is the carbon emission of electric vehicles at the end-of-life recycling stage (t), E t1,t is the carbon emission per unit of transportation function unit of electric vehicles under the disorderly charging scenario (t / km), and L is the expected life cycle mileage of electric vehicles (km).

[0073] b) When the electric vehicle charging scenario is an orderly charging scenario, the process of calculating the carbon emissions per unit of traffic function unit of the electric vehicle is:

[0074] In the orderly charging ("virtual energy storage") scenario, electric vehicles are charged during the low electricity consumption period, and the power grid does not need to increase power generation. In other words, electric vehicles do not cause carbon emissions in the upstream power production link, which is equivalent to zero carbon emissions in the use phase of electric vehicle transportation function modeling, that is:

[0075] E t2 =E t1 -E u

[0076]

[0077] Among them, E t2 is the total carbon emissions under the orderly charging scenario (t), E t2,t is the carbon emission per unit of transportation function unit of electric vehicles under the orderly charging scenario (t / km), E t1 is the total carbon emissions under disorderly charging scenario (t), E u is the carbon emission of electric vehicles during their use phase (t), and L is the expected life cycle mileage of electric vehicles (km).

[0078] c) When the electric vehicle charging scenario is a V2G energy storage scenario, the process of calculating the carbon emissions per unit of traffic function unit of the electric vehicle is:

[0079] 21) Calculate the V2G energy storage potential of electric vehicles;

[0080] The specific process of step 21) is:

[0081] Modeling and calculating the energy storage potential of electric vehicles mainly considers the battery characteristics of electric vehicles such as battery capacity and charging and discharging efficiency, travel characteristics such as owner's travel mode, travel mileage and power demand, and key influencing factors such as available charging infrastructure. The specific steps include:

[0082] 211) Based on the travel mileage requirements of the vehicle owner, a travel power demand constraint is established to ensure the main function of the electric vehicle, wherein the main function is a transportation function;

[0083] 212) Calculate the battery state of charge (SOC), i.e., the amount of electricity, when the electric vehicle enters the charging area;

[0084] 213) Calculate the V2G energy storage potential of electric vehicles based on the travel power demand constraints, parking time intervals, peak and valley times of power grid load, and charging and discharging efficiency of charging piles.

[0085] 22) Calculate the negative carbon emissions E of the electric vehicle V2G energy storage converted into reverse power generation function based on the electric vehicle V2G energy storage potential voe .

[0086] The specific process of step 22) is:

[0087] 221) Obtain the life expectancy of electric vehicles;

[0088] 222) calculating the energy storage during the life cycle of the electric vehicle based on the expected life of the electric vehicle and the V2G energy storage potential of the electric vehicle;

[0089] 223) converting the energy stored in the electric vehicle during its life cycle into reverse power generation in the power grid to obtain the carbon emissions generated by the upstream power production process;

[0090] 224) Taking the carbon emissions generated by the upstream power generation process as a negative value, we can obtain the negative carbon emissions E of the reverse power generation function. voe .

[0091] 23) Negative carbon emissions E according to the reverse power generation function voe Calculate the carbon emissions E per unit of traffic function unit of electric vehicles under the V2G scenario t3,t ;

[0092] The process of step 23) is:

[0093] In the V2G energy storage scenario, in addition to the orderly charging process not causing carbon emissions in the upstream power production link, its discharge process will also reduce the power generation of the power grid during peak power consumption, which is equivalent to the "reverse power generation" function. That is, in the modeling of electric vehicle transportation functions, the negative carbon emissions of the upstream power production process are considered in the use phase, and functional conversion is required, namely:

[0094] E t3 =E t1 -E u +E voe

[0095]

[0096] Among them, E t3 is the total carbon emissions under the V2G scenario (t), E voe The negative carbon emissions of electric vehicle V2G energy storage converted into reverse power generation function, E t3,t is the carbon emission per unit of traffic function unit of electric vehicles under the V2G scenario (t / km), E t1 is the total carbon emissions under disorderly charging scenario (t), E u is the carbon emission of electric vehicles during their use phase (t), and L is the expected life cycle mileage of electric vehicles (km).

[0097] It should be noted that the present invention decomposes the sources of carbon emissions involved in the transportation function and energy storage function of electric vehicles, finds their internal connection, and introduces the perspective of reverse power generation, regards electric vehicle energy storage as a reverse power generation process, and proposes the key reverse power generation transition function of electric vehicles from energy storage to transportation. Therefore, through the conversion path of electric vehicle energy storage-reverse power generation-negative carbon emissions from transportation, the functional integration of electric vehicle life cycle carbon emission calculation is realized, which is conducive to improving the integrity of electric vehicle life cycle carbon emission calculation, helping enterprises to provide electric vehicle carbon labels, helping the government to better understand the contribution of developing electric vehicles to my country's carbon reduction, and helping to promote the smooth implementation of my country's dual carbon strategy.
