The main innovation achieved by Jian Guo et al. [24] is a precise battery pack and cabin temperature control by means of different expansion valves dedicated to each heat exchanger. This solution is very helpful for the independence of the powertrain batteries and the cabin temperatures, but it is a complex proposal due to the articulated layout.
Due to the tight arrangement of the battery pack, there is a risk of thermal runaway under poor heat dissipation conditions. It is thus necessary to predict the power characteristics of the battery in advance and control the temperature of the battery pack.
(1) Stabilize the battery pack temperature to 45 °C; (2) The cold plate initiates operation, and the experiment concludes upon reaching a temperature of 25 °C for the high-temperature battery pack. Comparative analysis is conducted between the measured top and bottom battery temperatures and the numerical simulation outcomes (Fig. 8).
(1) A battery pack model and a thermal management system model are developed to precisely depict the electrical, thermal, aging and temperature inconsistency during fast charging-cooling. (2) A strategy for the joint control of fast charging and cooling is presented for automotive battery packs to regulate the C-rate and battery temperature.
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.
Temperature-Control Strategies The basic idea of a cooling method is to change the surface h and further reduce the battery temperature. 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.
Previous studies indicate that charging and discharging should be performed in a suitable temperature range of 20–45 °C , and the maximum temperature difference in the battery pack is generally maintained within 5 °C , .
