Contact UsThe 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 system can preheat the battery safely in the capacity range of 20%–100%. When the battery pack is set in −20 °C, the effective electric energy can be increased by 550% after preheating. An energy conversion model is also built to measure the relationship between the energy improvement of battery and the energy consumption by preheating.
In self-heating systems, a larger preheating current may result in overdischarge of the battery pack and damage the battery. Since this system can achieve a high heating rate using a relatively small current, it hardly damages the batteries. 3.2. Influence of the preheating system on battery performance 3.2.1.
Since a portion of heat is generated by the internal resistor of batteries, whereas the other portion is generated in the conductive cPCM, a relatively small preheating current can result in a high heating rate, thus reducing the risk of battery overcharge/overdischarge. Fig. 4.
3.2.1. Operating at different ambient temperatures When lithium-ion batteries are operated at low temperatures, the increase in the battery internal resistance eventually reduces the discharge voltage platform. Preheating can effectively increase the voltage of batteries at low temperatures.
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.
