S1, receiving an initial temperature value acquired by a temperature sensor, and acquiring a preset temperature mapping relation between a sampling temperature of the temperature sensor and a temperature calibration value, wherein the temperature calibration value is a difference value between a reference temperature acquired by a preset reference temperature sensor and the sampling temperature.
In particular embodiments, a temperature sensor is disposed in the energy storage system for detecting the temperature of the battery. The number of temperature sensors may be plural. The BMU (Battery Management Unit ) collects an initial temperature value of the temperature sensor, wherein the initial temperature value is an uncorrected temperature value. The temperature sensor may in particular be an NTC temperature sensor.
A preset temperature mapping relation between the sampling temperature of the temperature sensor and a temperature calibration value is preset, wherein the temperature calibration value is a difference value between the reference temperature acquired by the preset reference temperature sensor and the sampling temperature. The reference temperature sensor is a high-precision temperature sensor, and the acquired temperature is the reference temperature. The reference temperature may be considered as the actual temperature at the sampling point.
It will be appreciated that, before step S1 is performed, the preset temperature map is obtained in advance, and in an embodiment, the obtaining the preset temperature map includes the following steps:
s11, acquiring a plurality of sampling temperatures which are acquired by the temperature sensor correspondingly under a plurality of preset reference temperatures.
In specific implementation, during calibration, a reference temperature sensor and a temperature sensor are configured in the same temperature space, and a plurality of preset reference temperatures (temperatures acquired by the reference temperature sensor) are acquired through temperature adjustment, and the temperature sensor corresponds to the acquired plurality of sampling temperatures. The temperature sensor may be plural. The number of reference temperatures can cover the sampling range of the temperature sensor.
S12, determining a temperature calibration value based on the difference value between the reference temperature and the corresponding sampling temperature.
In a specific implementation, if the number of the temperature sensors is 1, a difference between a reference temperature and the corresponding sampling temperature is calculated and is used as a temperature calibration value corresponding to the sampling temperature.
In an embodiment, the number of the temperature sensors is plural, and the step of determining a temperature calibration value based on the difference between each of the reference temperatures and the corresponding sampled temperature includes calculating an average value of the difference between the reference temperatures and the sampled temperatures of the corresponding plurality of temperature sensors as the temperature calibration value.
In specific implementation, the difference values between the reference temperature and the sampling temperatures of the corresponding temperature sensors are calculated respectively, and the average value of the obtained difference values is further calculated, and is taken as the temperature calibration value.
Specifically, when calculating the average value, the average value may be calculated after removing a plurality of maximum values and a plurality of minimum values from the plurality of difference values.
For example, the sampling temperature of a plurality of the temperature sensors is T 1(x),T2(x)…TM(x). Wherein M is the total number of the temperature sensors, x is the reference temperature acquired by the high-precision reference temperature sensor, and-40 < = x < = 125 ℃, namely the sampling range of the temperature sensor. If T 3(10) is the temperature value acquired by the third temperature sensor in the BMU when the actual temperature is 10 ℃. And respectively calculating the difference DeltaT N between the reference temperature and the sampling temperatures of the corresponding temperature sensors, namely calculating DeltaT N(x)＝x-TN(x), wherein N is more than or equal to 1 and less than or equal to M, and the accuracy is 0.1 ℃ when-40 < = x < = 125 ℃.
S13, establishing and obtaining the preset temperature mapping relation based on the sampling temperature and a temperature calibration value corresponding to the sampling temperature.

Another way is: and fitting a plurality of groups of temperature calibration values corresponding to the sampling temperatures to obtain a preset functional relation, namely, the preset temperature mapping relation comprises the preset functional relation.
According to the scheme, the production efficiency of the BMS (Battery MANAGEMENT SYSTEM) can be greatly improved in the energy storage system. Specifically, not only the detection accuracy of the temperature sensor can be improved, but also a large amount of calibration work can be omitted. The temperature sensor of the same model can be repeatedly used by only manufacturing a preset temperature mapping relation once in the same circuit, and can automatically execute high-precision temperature calibration work during temperature detection, so that the temperature precision is less than 1 ℃ in the range of-40 < = x < = 125 ℃.
S2, determining a target temperature calibration value corresponding to the initial temperature value from the preset temperature mapping relation.
In a specific implementation, a temperature calibration value corresponding to the initial temperature value is determined as a target temperature calibration value according to the preset temperature mapping relation.

S22, if the initial temperature value is one sampling temperature in the preset temperature corresponding relation table, reading a target temperature calibration value corresponding to the initial temperature value from the preset temperature corresponding relation table.
In a specific implementation, if the initial temperature value is a sampling temperature in the preset temperature correspondence table, it is indicated that the target temperature calibration value corresponding to the initial temperature value is recorded in the preset temperature correspondence table, so that the target temperature calibration value corresponding to the initial temperature value can be directly read from the preset temperature correspondence table.
S23, if the initial temperature value is not one sampling temperature in the preset temperature corresponding relation table, acquiring a first temperature calibration value corresponding to the sampling temperature greater than the initial temperature value and a second temperature calibration value corresponding to the sampling temperature smaller than the initial temperature value from the preset temperature corresponding relation table.
In a specific implementation, if the initial temperature value is not a sampling temperature in the preset temperature correspondence table, a target temperature calibration value needs to be calculated. The calculation process needs to use two adjacent temperature calibration values, namely, a first temperature calibration value corresponding to a sampling temperature greater than the initial temperature value and a second temperature calibration value corresponding to a sampling temperature smaller than the initial temperature value are obtained from the preset temperature corresponding relation table.
S24, determining a target temperature calibration value corresponding to the initial temperature value through interpolation based on the first temperature calibration value and the second temperature calibration value.
In specific implementation, the target temperature calibration value corresponding to the initial temperature value is determined by a linear interpolation method, and a specific calculation formula is y=y1+ (Y2-Y1) × (X-X1)/(X2-X1), wherein Y is the target temperature calibration value, X is the initial temperature value, Y1 is the first temperature calibration value, Y2 is the second temperature calibration value, X1 is the sampling temperature corresponding to the first temperature calibration value, and X2 is the sampling temperature corresponding to the second temperature calibration value.
In an embodiment, the predetermined temperature mapping relationship includes a predetermined functional relationship between a sampling temperature and the temperature calibration value, and the step of determining, from the predetermined temperature mapping relationship, a target temperature calibration value corresponding to the initial temperature value includes: and calculating a target temperature calibration value corresponding to the initial temperature value by using the preset functional relation according to the initial temperature value.
In specific implementation, the initial temperature value is brought into the preset functional relation, and a target temperature calibration value corresponding to the initial temperature value is obtained through calculation.
S3, determining a calibration temperature value corresponding to the initial temperature value based on the target temperature calibration value.
In specific implementation, the initial temperature value is calibrated through the target temperature calibration value, and then the calibration temperature value corresponding to the initial temperature value can be obtained. Specifically, calculating the sum of the initial temperature value and the target temperature calibration value to obtain the calibration temperature value.
