FAQs about New energy battery constant temperature system detection
Why is it important to control battery temperature?
As the battery voltage continues to drop under constant power conditions, the battery current output will accordingly increase, which brings a risk of thermal runaway in instances of weak heat dissipation. Therefore, knowing how to control the battery temperature is very critical for safe use.
What are the different types of battery system temperature control strategies?
General battery system temperature-control strategies include: PID-based control, fuzzy-algorithm-based control, model-based predictive control, and coupling control in several ways. Cen et al. [ 10] used a PID algorithm to design an air-conditioning system for an electric vehicle to accomplish air circulation in the vehicle and the battery pack.

Without discussing the specific cooling methods, this work developed a temperature-control strategy to keep battery temperature within a certain threshold on the basis of model prediction.
How is characteristic prediction performed under constant power conditions?
Characteristic prediction under constant power conditions is then conducted based on an iterative solution method. Validations of characteristic prediction indicate the convenience of the developed models, with average absolute errors of voltage and temperature less than 36 mV and 0.4 K, respectively, and power error less than 0.005%.
Why is the temperature distribution in a battery uniform?
The temperature distribution inside the battery is uniform. In order to reduce the complexity of battery modeling and simulation time, this work ignores the temperature difference at different positions inside the battery, referring to a lumped-parameter thermal model. The resistance of wires in the battery pack is ignored.
