In the design of a project, the first step must be to clarify the customer's needs.
What is the cooling load of a battery?
Here, the cooling load depends on the difference between the maximum operating temperature of the battery (such as 35°C, 40°C, 45°C, 50°C) and the initial temperature of 25°C (∆T).
How do you calculate the heating power of a battery pack?
Calculate the sum of all the heat required to heat up the battery pack components and the heat dissipated by the box to obtain the total heat of heating. Then according to the specific requirements of the heating time, the corresponding heating power is obtained.
How do you calculate the calorific value of a battery pack?
The calorific value of the battery pack is calculated according to the sum of the calorific value of all cells in the battery pack and the sum of the calorific value of the connection resistance.
What temperature should battery cells be kept in a cooling unit?
The cooling unit must ensure the maximum temperature of the battery cells within the container does not exceed the threshold set by the battery manufacturer (such as 45°C or 50°C) at the end of these cycles. Operating battery cells above 35°C accelerates aging, resulting in faster degradation.
