Firstly, the heating model of battery modules is established in the software of finite element analysis and the results are calculated. Secondly, the experiment is conducted using the PTC method, which shows that this method greatly improves the performance of lithium-ion power batteries at low temperature.
The heating power is studied for different BPC parameters. A novel non-destructive BPC heating method is developed. Low temperatures seriously affect the performance of lithium-ion batteries. This study proposes a non-destructive low-temperature bidirectional pulse current (BPC) heating method.
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.
In the field of battery thermal management systems (BTMS), low-temperature heating is a core technology that cannot be ignored and is considered to be a technical challenge closely related to thermal safety.
Generally speaking, low-temperature heating strategies are commonly divided into external, internal, and hybrid heating methods, considering the constant increase of the energy density of power battery systems. In a study conducted by Sun et al. , the thermal and rheological attributes of a nanofluid were scrutinized.
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.
