The specific test results are shown in table 1 below.
TABLE 1
It should be noted that the acceleration referred to in table 1 and the foregoing text refers to an absolute value, i.e., includes both acceleration and deceleration conditions.
As can be seen from table 1, in the rest mode, there is a slight, negligible battery radiation at the dashboard. In the constant-speed driving mode, except for the steering wheel, the instrument panel, the floor and the front passenger seat are all provided with trace battery radiation, which indicates that the radiation quantity is irrelevant to the speed of a new electric automobile. The radiation generated by the electric vehicle is not enough to cause harm to human bodies, but the high radiation (compared with the radiation generated in other modes) is generated instantaneously when the electric vehicle is accelerated, and the radiation is obviously reduced after the electric vehicle is driven smoothly due to the release and recovery of the kinetic energy of the driving motor. When in the run-up module, battery radiation at the floor is most severe.
And analyzing the test result: from the driver's point of view, the battery radiation of the steering wheel and the dashboard is negligible, so that the damage of the battery radiation to the driver is essentially absent. From a copilot point of view, the battery radiation of the instrument panel and the seat is negligible, so that the harm of the battery radiation to the passenger in the copilot position is substantially absent. From the point of view of the passengers, the radiation of the battery at the floor is greatest, the type of person who is liable to contact the floor for a long time is generally a child, who falls more easily from the seat to the floor in acceleration and deceleration conditions, thus increasing the contact time with the floor, and is relatively more exposed to radiation.
Based on this, in one embodiment of the invention, the method further comprises: and generating a radiation protection scheme aiming at each preset position according to the radiation amount detection result.
As mentioned above, the preset positions include, for example: one or more of a steering wheel, a dashboard, an interior floor, and a front passenger seat. Based on this, the radiation protection scheme aiming at each preset position comprises the following steps: moving passengers away from the interior floor or reducing contact time with the interior floor; and/or laying a radiation isolation material on the upper layer of the floor in the vehicle to isolate radiation, so as to reduce radiation injury to human bodies. In other words, for children, special protection measures can be provided, which are fixed away from the floor or reduce the contact time with the floor by installing a child seat or other means in acceleration and deceleration states. Further, an isolation material can be arranged on the upper layer of the vehicle floor to isolate and weaken battery radiation, so that radiation damage to the body is reduced.
In a specific embodiment, the variable can be set as a battery parameter, the non-variable can be set as a vehicle speed and/or an acceleration, and then the radiation quantity of the battery of the electric vehicle can be accurately detected through a variable control method, so that a reliable basis is provided for avoiding and reducing radiation, and radiation injury to people in the vehicle is reduced. For example, for a high-nickel ternary lithium ion battery, environmental parameters, a vehicle speed and/or acceleration can be kept unchanged, different contents of nickel, cobalt and manganese are set, and then the radiation amount is detected.
According to the method for detecting the radiation quantity of the battery of the electric automobile, the vehicle to be detected is selected, and the variable parameter and the non-variable parameter of the vehicle to be detected are determined; according to the variable parameter, the radiant quantity detection is carried out on the preset position of the vehicle to be detected, and the radiant quantity detection result is output, namely, according to the variable control method, the radiant quantity of the battery of the electric automobile can be accurately detected, so that the reliable basis for avoiding and reducing radiation is provided, and the radiation injury to personnel in the automobile is reduced.

Specifically, the battery parameters include the content of each chemical element in the battery. And adjusting the parameters of the battery, namely adjusting the content of each chemical element. For example, for a high-nickel ternary lithium ion battery, different contents of nickel, cobalt and manganese can be adjusted, and then the radiation amount is detected.
In one embodiment of the present invention, the system 100 further comprises a processing module (not shown in the figures). The processing module is used for generating a radiation protection scheme aiming at each preset position according to the radiation amount detection result.
As mentioned above, the preset positions include, for example: one or more of a steering wheel, a dashboard, an interior floor, and a front passenger seat. Based on this, the radiation protection scheme generated by the processing module for each preset position comprises: moving passengers away from the interior floor or reducing contact time with the interior floor; and/or laying a radiation isolation material on the upper layer of the floor in the vehicle to isolate radiation, so as to reduce radiation injury to human bodies. In other words, for example, special protection measures can be provided for children, by mounting a child seat or otherwise, in the acceleration and deceleration states, so as to be away from the floor or to reduce the contact time with the floor. Further, an isolation material can be arranged on the upper layer of the vehicle floor to isolate and weaken battery radiation, so that radiation damage to the body is reduced.
In a specific embodiment, the determining module 120 may further set the variable as a battery parameter, and set the non-variable as a vehicle speed and/or an acceleration, and further, the detecting module 130 may accurately detect the radiation amount of the battery of the electric vehicle through a variable control method, so as to provide a reliable basis for avoiding and reducing radiation, so as to reduce radiation injury to people in the vehicle. For example, for a high-nickel ternary lithium ion battery, environmental parameters, a vehicle speed and/or acceleration can be kept unchanged, different contents of nickel, cobalt and manganese are set, and then the radiation amount is detected.
It should be noted that a specific implementation manner of the system for detecting radiation amount of an electric vehicle battery according to the embodiment of the present invention is similar to a specific implementation manner of the method for detecting radiation amount of an electric vehicle battery according to the embodiment of the present invention, and please refer to the description of the method part specifically, and details are not repeated here in order to reduce redundancy.
