Low-temperature lithium batteries are crucial for EVs operating in cold regions, ensuring reliable performance and range even in freezing temperatures. These batteries power electric vehicles’ propulsion systems, heating, and auxiliary functions, facilitating sustainable transportation in chilly environments. Outdoor Electronics and Equipment
Last but not the least, battery testing protocols at low temperatures must not be overlooked, taking into account the real conditions in practice where the battery, in most cases, is charged at room temperature and only discharged at low temperatures depending on the field of application.
By applying rectangular pulse waveform at 10 A and 30 Hz, the proposed strategy could heat batteries from −24 °C to 25.6 °C within 600 s. Besides, the pulsed self-heating strategy at low temperatures also ensured fast and safe preheating performance. .
The ultimate goal of battery preheating is to recover battery performance as quickly as possible at low temperatures while considering battery friendliness, temperature difference, cost, safety and reliability. A systematical review of low temperature preheating techniques for lithium-ion batteries is presented in this paper.
Nevertheless, low-temperature environments greatly reduce the performance of lithium-ion batteries, especially at subzero temperatures. Charging at low temperature will induce lithium deposition, and in severe cases, it may even penetrate the separator and cause internal short, resulting in an explosion.
He et al. proposed a hybrid heating strategy (Fig. 42). This strategy could not only balance the temperature between different batteries in the module but could also ensure that the battery module was preheated at low temperatures. The experimental results are shown in Fig. 43.
