The battery pack geometric model A Battery Electric Vehicle's energy storage system can be seen as a complex system in structural terms. It consists of several battery cells optimally positioned to save space in the EV and to improve heat exchange between the battery cells and the cooling system.
The power battery pack of the target vehicle is connected with the structural bolts of the vehicle chassis through the lifting lugs welded on the lower box of the battery pack. The battery pack box of the target vehicle is arranged under the chassis, below the floor of the passenger compartment, disassembled from the electric vehicle.
Conclusions This study developed a model-based methodology for use in the design of battery packs for automotive applications. This methodology is based on a multi-domain simulation approach to allow electric, thermal and geometric evaluations of different battery pack configurations, with particular reference to Li-NMC technology.
The power battery pack provides energy for the whole vehicle, and the battery module is protected by the outer casing. The battery pack is generally fixed at the bottom of the car, below the passenger compartment, by means of bolt connections. The safety of the power battery pack is one of the important indicators to measure the safety of BEVs.
This study focuses on the development of dynamic battery models for EV applications. The models are based on the second-order ECM technique and developed using the Modelica language for four different types of Li-ion cell chemistry commonly found in commercial EVs. The thermal behavior of the battery at the cell level is also considered.
These include the following: The EV powertrain, including physical models of the battery pack (array of cells connected in series and in parallel), the electric motor, the electric drive, and the mechanical drivetrain of the vehicle. The EV system-level model is presented in Figure 3.
