Customer ServiceHence, as mentioned in section 3.9, a DOE for different ambient temperatures and initial Battery temperatures and this was done for different configurations of the cooling system. The configurations of cooling system were changed by using the control valves to direct the flow to either of the heat exchangers (Chiller or Radiator) or both.
Heat generated by the Battery and the changes in its temperature during the simulation plays a major role in the variation in Coolant temperatures which is the main output from the Battery model for operation of the cooling system.
Maintaining an optimal temperature is essential as it increases safety, reduces maintenance cost, and increases the service life of the battery pack. When choosing a cooling technique various trade-offs are made among various parameters like weight, cooling effect, temperature consistency, and cost.
The current cooling package configuration consists of a Condenser sandwiched between 2 Radiators, one each for Battery cooling system and electrical cooling system separately.
Battery cooling can be classified into two types1. Passive cooling 2. Active cooling based on the control strategies. In the passive cooling the coolant is cooled with the help of air through parallel flow heat exchanger whereas in active cooling the coolant is forcefully cooled with the help of the refrigerant through the internal heat exchanger.
As seen in Figure 3-1, two of the cooling systems as a part of the complete vehicle cooling systems category are the Battery cooling system and the Electrical components cooling system.
