Description
The technical field is as follows:
the invention relates to a method for checking the shielding performance of a power battery system of a pure electric vehicle, and belongs to the technical field of pure electric vehicles.
Background art:
with the continuous promotion of the market demand of pure electric vehicles, the vehicle type configuration is updated frequently, especially a power battery system closely related to the endurance mileage, and the appearance size of the battery pack is closely related to the external shielding property of the whole vehicle. The overlarge battery container is easy to expose, so that the subjective feeling of a user is directly influenced, the competitiveness of a product is reduced, the ground clearance of the whole vehicle can be reduced, and the trafficability of the whole vehicle is poor. Excessive reduction in battery pack size also increases battery system cost due to cell size and manufacturing process limitations. Therefore, in the data design stage, it is necessary to provide a reasonable battery boundary area on the premise of meeting the shielding performance of the whole vehicle.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the invention provides a method for checking the shielding performance of a power battery system of a pure electric vehicle, which aims to solve the problems in the prior art, and can quickly find a reasonable area to meet the shielding performance requirement of the whole vehicle.
The technical scheme adopted by the invention is as follows: a method for checking the shielding performance of a power battery system of a pure electric vehicle comprises the following specific steps:
the method comprises the following steps: taking an observation line, a whole vehicle side wall projection line and SAE 5% human eyepoint as a parameterization template;
step two: designing and inputting: the outer surface of the whole vehicle, the envelope of a battery system and the ground line of the whole vehicle;
step three: making a whole vehicle side wall projection line to the ground, drawing an observation line at a position 5000mm away from the side wall projection line, and placing an SAE 5% female human body;
step four: drawing a first visual field line from an eye point of SAE 5% female human body, wherein the first visual field line is tangent to a side wall line of the whole vehicle and is intersected with a ground line of the whole vehicle;
step five: making a second sight line parallel to the first sight line and offset downwards by 8 mm;
step six: and taking the first sight line as a contour, and stretching along the ground line direction of the whole vehicle to form a region meeting the shielding property of the whole vehicle.
Further, if the envelope of the battery system is positioned above the shielding area of the whole vehicle, the power battery system meets the shielding requirement.
Further, if the battery system is satisfied between the first sight line and the second sight line, the battery system is within the acceptable range.
Further, if the envelope of the battery system is below the second sight line, the requirement for shielding performance of the whole vehicle is not met.
The invention has the following beneficial effects: the method for checking the shielding property of the power battery system of the pure electric vehicle can not only provide a power battery installation area meeting the shielding property of the whole vehicle in a data design stage, but also be used for checking whether the shielding property of the power battery system of the conventional vehicle type meets the requirement or not, and quickly provides a correction suggestion.
The specific implementation mode is as follows:
the invention discloses a method for checking the shielding performance of a power battery system of a pure electric vehicle, which comprises the following specific steps:
the method comprises the following steps: taking an observation line, a whole vehicle side wall projection line and SAE 5% human eyepoint as a parameterization template;
step two: designing and inputting: the outer surface of the whole vehicle, the envelope of a battery system and the ground line of the whole vehicle;
step three: making a whole vehicle side wall projection line to the ground, drawing an observation line at a position 5000mm away from the side wall projection line, and placing an SAE 5% female human body;
step four: drawing a first visual field line from an eye point of SAE 5% female human body, wherein the first visual field line is tangent to a side wall line of the whole vehicle and is intersected with a ground line of the whole vehicle;
step five: making a second sight line parallel to the first sight line and offset downwards by 8 mm;
step six: and taking the first sight line as a contour, and stretching along the ground line direction of the whole vehicle to form a region meeting the shielding property of the whole vehicle.
If the envelope of the battery system is positioned above the shielding area of the whole vehicle, the power battery system meets the shielding requirement, and in addition, if the battery system is between the first sight line and the second sight line, the power battery system belongs to an acceptable range; if the envelope of the battery system is below the second sight line, the requirement of shielding performance of the whole vehicle is not met, and the arrangement output meets the requirement of region design data adjustment and optimization.
The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
