To achieve fine control of multilayer temperature uniformity and energy consumption in a battery thermal management system (BTMS), a model predictive control (MPC) based on the reduced-order model and the heat generation previewer is proposed in this work. A direct contact liquid cooling battery pack is adopted to verify the control strategy.
However, the capacity of the battery relies heavily on the working temperature. As the temperature increases, the capacity is deteriorated rapidly due to the decomposition of the electrolyte and other side reactions favored by the high temperature.
Ping, Peng, Kong, Chen, and Wen (2018) proposed a novel PCM and fin structure for the thermal management system for a LiFePO 4 battery module to reduce the maximum temperature and improve the temperature uniformity for high-temperature environment (40 °C) applications.
When a discharge rate of 0.5C is used, the difference between extreme temperatures in the battery pack remains under 2 °C while the temperature profile throughout the discharge process exhibits improved stability. Moreover, when the discharge rate is raised to 1.5C, the maximum temperature difference inside the pack slightly increases to 2.5 °C.
In this paper, we introduce a proportional-integral-derivative ( PID) control loop algorithm to control the real-time thermal behavior of a battery module such as the peak temperature and temperature distribution across the module.
Besides, the temperature difference of the cell, module, and pack level can be limited to 0.8 °C, 1 °C, and 2 °C, respectively, decreasing the state of health difference among the cells. For energy consumption, the proposed method improves up to 56.48%.
The Importance of Temperature Control in Battery Management
Give the battery an air conditioner, and you get battery thermal management, which accomplishes three essential functions: heat dissipation, heating, and temperature consistency. When temperatures soar, batteries can experience a dramatic loss of life (resulting in capacity degradation) and an elevated risk of thermal runaway.
