Figure 2 As shown, the process includes the following steps: Step S1: Obtain the demand information of the target component of the power battery over the full temperature range, wherein the demand information includes at least one of the following: power demand, nominal voltage, and size boundary. Step S2: Based on the demand information, determine the heat generation demand of the target component and the allowable size of the target component. Compare the heat generation demand with the heat generation generated by the preset heat generation path to obtain a first comparison result, wherein the preset heat generation path includes at least one of the following: upper liquid cooling plate heating, lower liquid cooling plate heating, battery pulse heating, and battery built-in heating plate heating. When the first comparison result meets the first preset condition, compare the allowable size of the target component with the total size of the preset target component in the preset heat generation path to obtain a second comparison result. Step S3: When the second comparison result meets the second preset condition, determine the heating method and size of the target component based on the first comparison result and the second comparison result. Among them, the first preset condition is that the heat generation generated by the preset heat generation path is greater than or equal to the heat generation demand, and the second preset condition is that the total size of the preset target component is less than or equal to the allowable size of the target component.

[0030] In the embodiment of the present application, by obtaining the demand information of the target component of the power battery over the full temperature range, the heat generation demand and the allowable size of the target component are determined according to the demand information, the heating method of the target component is first determined, and then the size of the target component is determined according to the preset target component corresponding to the heating method. In the above-mentioned integration method, the heating method of the power battery is first integrated to meet the temperature rise requirements of the battery in cold areas, thereby ensuring the low-temperature range of the electric vehicle. On the basis of meeting the temperature rise requirements of the power battery, the target component is structurally improved and sized, taking into account the heat generation of the target component and the built-in space of the power battery.

[0031] Optionally, in step S3, based on the first comparison result, the heating method of the target component is determined, including: when the first comparison result does not meet the first preset condition, on the basis of the current heat generation, the heat generated by any preset heat generation path is superimposed to form a first updated heat generation, wherein the preset heat generation path corresponding to the superimposed heat generation is different from the preset heat generation path corresponding to the current heat generation; the first updated heat generation is compared with the heat generation demand to obtain a third comparison result; when the third comparison result meets the first preset condition, the heating method of the target component is determined. In the above steps, the heating method of the target component is determined by superimposing the heat generation corresponding to different preset heat generation paths and then judging, wherein the heating method is an integration of multiple different preset heat generation paths.

[0032] Optionally, in step S3, based on the first comparison result, determining the heating method of the target component also includes: when the third comparison result does not meet the first preset condition, on the basis of the first updated heat generation, continuing to add the heat generated by any preset heat generation path until the first preset condition is met; wherein the preset heat generation path corresponding to the heat generation that continues to be added is different from the preset heat generation path corresponding to the previous heat generation. In the above steps, the heat generation requirement of the target component is achieved by continuously adding the heat generation to try to meet the temperature rise requirement of the battery in cold regions.

[0033] Optionally, based on the first comparison result, determining the heating method of the target component also includes: comparing the second updated heat generation formed by superimposing the heat generation generated by all the preset heat generation pathways with the heat generation demand to obtain a fourth comparison result; if the fourth comparison result does not meet the first preset condition, determining the heating method of the target component as the integration of all the preset heat generation pathways. In the above steps, by integrating all the preset heat generation pathways to meet the heat generation demand of the target component to the maximum extent, the situation of rapid decline in the cruising range of the electric vehicle due to low temperature is reduced.

[0034] Optionally, the heat generated by the preset heat generation pathway is a heat generation set. Before comparing with the heat generation demand, the maximum heat generation in the heat generation set needs to be obtained, and the heat generation demand is compared with the maximum heat generation. The maximum heat generation in the heat generation set is selected for comparison. The purpose is to select the preset heat generation pathway with a larger heat generation for integration under the premise that the heat generation demand and the integration number of the preset heat generation pathways are equal, so as to maximize the temperature rise rate of the battery while meeting the temperature rise demand of the battery in severe cold areas.

[0035] Optionally, when the first comparison result satisfies the first preset condition, the allowable size of the target component is compared with the total size of the preset target component in the preset heat generation path to obtain a second comparison result, and the size of the target component is determined based on the second comparison result, including: when the second comparison result does not meet the second preset condition, a second control instruction is generated, and the second control instruction is used to integrate the structure of the preset target component to remove interference between parts. On the premise of meeting the heat generation demand, the structure of the preset target component is improved to remove interference between the preset target components and between the preset target component and the battery housing. Specifically, structural integration can be performed by secondary design of the structure of the parts, integrated design of multiple parts, and integrated design between components to meet the allowable size of the target component.

[0036] Optionally, based on the demand information, the heat generation demand of the target component and the allowable size of the target component are determined, including: determining the cell model, cell size and number of cell strings of the power battery based on the power demand and the nominal voltage; calculating the heat generation demand and the allowable size of the target component based on the number of cell strings, the cell's own properties, the preset temperature rise rate, the preset temperature rise time and the size boundary. Among them, the cell's own properties include cell mass, cell specific heat capacity, cell heat dissipation, etc. Specifically, the heat generation demand is calculated based on the number of cell strings, cell mass, cell specific heat capacity, preset temperature rise rate, preset temperature rise time and cell heat dissipation. Based on the size boundary, cell size and number of cell strings, the allowable size of the accessories of the power battery is calculated.

The upper surface of the upper water-cooled plate 4 is coated with phase change material for heat preservation, and the lower surface of the upper water-cooled plate 4 is integrated with the sampling plate of the module 3 using ceramic material to improve the heating and cooling rate and save space.

[0039] Figure 4 is a control flow chart of a method for integrating all-weather power batteries in one optional embodiment of the present application, such as Figure 4 As shown, the process includes the following steps:

[0040] Step S10: Determine the power demand, nominal voltage, boundary range and other demand parameters of the power battery in the full temperature range, wherein the boundary range of the power battery is (X, Y, Z).

[0041] Step S20: Select the battery cell according to the required parameters, and determine the number of battery cell strings, battery cell size, module size, and battery accessory size. The number of battery cell strings is S, the battery cell size is (X1, Y1, Z1), the module size space is (X2, Y2, Z2), and the battery accessory size is (X3, Y3, Z3).

[0042] The formula for calculating the battery accessory size is as follows:

[0043] X3=X-(X1*S+K1)-N1*b1,

[0044] Y3=Y-(Y1*S+K2)-N2*b2,

[0045] Z3=Z-(Z1*S+K3)-N3*b3.

[0046] Among them, K1, K2, and K3 are the dimensions of module accessories, N1, N2, and N3 are the dimensions of the high-voltage wire harness, and b1, b2, and b3 are the coefficients of the dimensions of the high-voltage wire harness.

[0047] Step S30: Calculating the heat generation requirement of the power battery according to the heating rate requirement of the power battery and the battery cell parameters.

[0048] The calculation formula for the heat generation demand of the power battery is as follows:

[0049] Q B =cmM*t+Q DIS .

[0050] Among them, Q B is the heat demand, Q DIS is the heat dissipation of the battery cell, t is the preset temperature rise time, M is the preset temperature rise rate, the mass of the battery cell is m, and the specific heat capacity of the battery cell is c.

[0051] Step S40: According to the heat generation demand of the power battery, simulate and calculate whether the maximum heating scheme of the preset heat generation path can meet the heat generation demand of the power battery. Among them, the preset heat generation paths are: upper liquid cooling plate heating, lower liquid cooling plate heating, battery pulse heating and battery built-in heating plate heating. The heat generated by the upper liquid cooling plate heating is Q1, the heat generated by the lower liquid cooling plate heating is Q2, the heat generated by the battery pulse heating is Q3, and the heat generated by the battery built-in heating plate heating is Q4. The specific simulation calculation steps are as follows:

[0052] If max(Q1, Q2, Q3, Q4) ≥ Q B , then determine the battery system heating plan.

[0053] If max(Q1, Q2, Q3, Q4)≤Q B , the heat generated by the two preset heat generation pathways is superimposed, and the simulation calculation is continued. If max(Q1+Q2, Q1+Q3, Q1+Q4, Q2+Q3, Q3+Q4)≥Q B , then determine the battery system heating plan.

[0054] If max(Q1+Q2, Q1+Q3, Q1+Q4, Q2+Q3, Q3+Q4)≤Q B, add up the heat generated by the three preset heat generation pathways, and continue the simulation calculation. If max(Q1+Q2+Q3, Q2+Q3+Q4, Q1+Q2+Q4)≥Q B , then determine the battery system heating plan.

[0055] If max(Q1+Q2+Q3, Q2+Q3+Q4, Q1+Q2+Q4)≤Q B , there is no need to continue the simulation calculation, and the battery system heating scheme is determined to take into account the four preset heat generation paths.

[0056] Or, when max(Q1+Q2+Q3, Q2+Q3+Q4, Q1+Q2+Q4)≤Q B , the heat generated by the four preset heat generation pathways is superimposed, and the simulation calculation is continued, regardless of whether (Q1+Q2+Q3+Q4) is greater than or equal to Q B , it is determined that the battery system heating scheme takes into account the four preset heat generation methods.

[0057] Step S50: Determine the heating method of the power battery according to the simulation calculation.

[0058] Step S60: According to the determined heating method, check whether the preset target component corresponding to the preset heat generation path can meet the battery accessory size. For example, the heating scheme in this embodiment takes into account four preset heat generation paths, and the size check is as follows:

[0059] If X 上 +X 下 +X 片 ≤X3,Y 上 +Y 下 +Y 片 ≤Y3 and Z 上 +Z 下 +Z 片 ≤Z3, then the all-weather power battery system design is met.

[0060] If X 上 +X 下 +X 片 >X3、Y 上 +Y 下 +Y 片 >Y3 and Z 上 +Z 下 +Z 片 >If at least one of Z3 is true, the component integration plan is determined, and the size-interfering parts are structurally integrated once or multiple times until the size requirements are met.

[0061] Among them, (X 上 , Y 上 , Z 上) is the size of the upper liquid cooling plate, (X 下 , Y 下 , Z 下 ) is the size of the upper liquid cooling plate, (X 片 , Y 片 , Z 片 ) is the size of the built-in heater.
