At present, a temperature sensor is an essential component of a temperature detection system of an electric vehicle as an information source of the temperature detection system of the electric vehicle.

The calculated temperature variation amounts of the three channels for the 2 nd frame data, the 3 rd frame data, the 4 th frame data and the 5 th frame data are shown in table 1, and are not described herein again. In the case of the 4 th frame data, since the temperature value of the channel 3 in the 3 rd frame data is invalid, the temperature value of the channel 3 of the 2 nd frame data is subtracted from the temperature value of the channel 3 of the 4 th frame data when the temperature variation of the channel 3 is calculated.

And thirdly, judging whether each channel is a first effective channel. The temperature processing device compares the temperature variation of the current frame of each channel with a first threshold value 1, if the temperature variation of the channel is less than 1, the channel is determined to be a first effective channel, and the fifth step is carried out; and if the temperature variation of the channel is greater than or equal to 1, the channel is not the first effective channel, and the fourth step is carried out.

For frame data 1, the temperature variation of channel 1 is 0.42, the temperature variation of channel 2 is 0.49, and the temperature variation of channel 3 is 0.16, which are all less than 1, so that channel 1, channel 2, and channel 3 are all regarded as the first effective channel, and may be labeled as first effective channel 1, first effective channel 2, and first effective channel 3. Similarly, it can be determined that channel 1, channel 2, and channel 3 are the first valid channels for frame 2 data, frame 4 data, and frame 5 data.

For the data of frame 3, the temperature variation of channel 1 is 0.08 and the temperature variation of channel 2 is 0.24, both of which are smaller than 1, and therefore, channel 1 and channel 2 are taken as the first effective channels; and the temperature variation of channel 3 is 20.19, which is greater than 1, so channel 3 is not the first active channel.

The temperature processing device compares the temperature variance of each first effective channel with a second threshold value 1, if the temperature variance of the first effective channel is less than 1, the channel is determined to be a second effective channel, and the eighth step is carried out; if the temperature variance of the channel is greater than or equal to 1, the channel is not the second valid channel and the seventh step is entered.

For the frame data of 1 st, the temperature variance of the first effective channel 1 is 0.24, the temperature variance of the first effective channel 2 is 0.23, and the temperature variance of the first effective channel 3 is 0.26, which are all less than 1, so that the first effective channel 1, the first effective channel 2, and the first effective channel 3 are all used as the second effective channel, which can be labeled as the second effective channel 1, the second effective channel 2, and the second effective channel 3. Similarly, it can be determined that the first effective channel 1, the first effective channel 2, and the first effective channel 3 are all the second effective channels for the 2 nd frame data, the 4 th frame data, and the 5 th frame data.

For the frame data of 1 st, the absolute value of the difference between the current frame temperature value 18.52 of the second effective channel 1 and the current frame temperature value 18.55 of the second effective channel 2 is calculated to be 0.03, the absolute value of the difference between the current frame temperature value 18.52 of the second effective channel 1 and the current frame temperature value 18.97 of the second effective channel 3 is calculated to be 0.45, and 0.03 and 0.45 are comparison values corresponding to the second effective channel 1. Similarly, the comparison values 0.03 and 0.42 for the second valid channel 2 and 0.04 and 0.05 for the second valid channel 3 can be calculated.

Similarly, for the 2 nd frame data, the 4 th frame data and the 5 th frame data, the comparison value corresponding to the second effective channel 1, the comparison value corresponding to the second effective channel 2 and the comparison value corresponding to the second effective channel 3 may be calculated respectively.

And counting the number of comparison values smaller than the third threshold in the comparison value corresponding to the second effective channel by the temperature processing device, and if the number of comparison values smaller than the third threshold in the comparison value corresponding to the second effective channel is greater than a preset value 0, taking the second effective channel as the third effective channel, and then entering the eleventh step. And if the number of comparison values which are greater than or equal to the third threshold value in the comparison values corresponding to the second effective channel is equal to 0, entering a tenth step.

For the data of the 1 st frame, the comparison values 0.03 and 0.45 corresponding to the second effective channel 1 are both smaller than 1, the number of the comparison values smaller than 1 is 2 and larger than 0, and the second effective channel is taken as a third effective channel and is marked as a third effective channel 1. Similarly, it can be determined that the second effective channel 2 and the second effective channel 3 are third effective channels, and are respectively marked as a third effective channel 2 and a third effective channel 3.

And step eleven, obtaining the output temperature value of the current frame. The temperature processing device calculates the average value of the current frame temperature values of the third effective channels as the current frame output temperature value.
