The features and the performance of each preheating method are reviewed. The imposing challenges and gaps between research and application are identified. Preheating batteries in electric vehicles under cold weather conditions is one of the key measures to improve the performance and lifetime of lithium-ion batteries.
The RTR was found to be 4.29 ℃/min. The preheating process lasted for 23 and 71 s when using 11 and 9.5 A respectively. The short preheating time was due to the significant polarization of the lithium-ion battery. Large discharge current and consequent battery polarization can lead to severe degradation of batteries.
Alternating current (AC) preheating AC preheating is a method that applies an AC with a prescribed frequency and amplitude to the positive and negative electrodes of the battery for generating heat through the internal impedance of the battery [96, 97].
Under the premise of ensuring safe operation of the lithium-ion battery, the optimal preheating performance was achieved. The results showed that the RTRs of the battery cell and four series of the battery pack from −20.3 °C to 10.02 °C are 2.21 ℃/min and 2.59 ℃/min, respectively.
Due to low thermal conductivity and high space requirement, air preheating is only suitable for early generation EVs with low energy density batteries. At the moment, liquid preheating is the most commonly used method since it has demonstrated good preheating performance and consistent temperature distribution.
The battery lifetime in DC preheating was found to be only 81 cycles . With DC heating, the battery can be preheated by directly discharging the energy stored in the battery. Since no additional equipment is required, the cost is low and it is relatively easy to implement.
