While the popularity of lithium-ion batteries (LIBs) has increased significantly in recent years, safety concerns due to the high thermal instability of LIBs limit their use in applications with zero tolerance for a catastrophic failure. Industries such as aerospace and automotive must be very stringent in their selection and design of lithium-ion cells and modules to meet safety requirements. A safety issue of particular interest is a scenario called thermal runaway in which one or more exothermic side-reactions occur, leading to elevated temperature ranges that in turn lead to an uncontrollable and excessive release of heat. This work aims to characterize the effect of these reactions by utilizing a thermal abuse model that predicts single-cell behavior when subjected to an elevatedtemperature. The experimental test of the thermal safety behavior includes a constant-power heating element to trigger a thermal runaway event. This study takes an existing thermal abuse model and modifies it to emulate the conditions during a constant-power heating test. The result is found to be in agreement with the experimental data for different cell configurations. The influence of convection condition, cell physical configuration, and electrolyte combustion on the cell thermal behavior is also investigated.

“…Additionally, the temperature dependence of HG causes the performance of the battery to be strongly dependent on thermal management [13,15,[19][20][21][22][23].The failure to take necessary steps can promote failures at the battery package [24]. A prerequisite for an effective BTMS is an accurate thermal model.…”

“…In this way, it helps to find the required specifications and configurations of BTMS for the better battery system performance. To model the non-uniformity of the cell temperature, several modelling methods have been adopted [24][25][26][27][28][29][30]. Moreover, the effectiveness and limitations of these methods are concisely discussed from the thermal behavior of the investigated cells in different review literature [31,32].…”

“…Nevertheless, battery degradation is accelerated at extremely low temperatures. These factors not only greatly shorten the driving range of vehicle, but also cause a great damage to battery [1,2]. In other words, whether the working temperature of battery is appropriate concerns not only the safety of EV but also efficiency and life of battery.…”

This paper presents an optimized energy management strategy for Li-ion power batteries used on electric vehicles (EVs) at low temperatures. Under low-temperature environments, EVs suffer a sharp driving range loss resulted from the energy and power capability reduction of the battery. Simultaneously, because of Li plating, battery degradation becomes an increasing concern as temperature drops. All these factors could greatly increase the total vehicle operation cost. Prior to battery charging and vehicle operating, preheating battery to a battery-friendly temperature is an approach to promote energy utilization and reduce total cost. Based on the proposed LiFePO4 battery model, the total vehicle operation cost under certain driving cycles is quantified in the present paper. Then given a certain ambient temperature, a target temperature of preheating is optimized under the principle of minimizing total cost. As for the preheating method, a liquid heating system is also implemented on an electric bus. Simulation results show that the preheating process becomes increasingly necessary with a decreasing ambient temperature; however, the preheating demand declines as driving range grows. Vehicle tests verify that the preheating management strategy proposed in this paper is able to save total vehicle operation cost.
