Parameter Identification of Lithium Iron Phosphate Battery Model for Battery Electric Vehicle

The Electric Vehicle Lithium Battery Monitoring System

With the global increase in the number of vehicles, environmental protection and energy issues had become increasingly prominent. People paid more and more attention to the electric vehicle as the future direction of the vehicle, but because the battery technology was relatively backward, it had become the bottleneck in the development of electric vehicles. So in the existing conditions, a perf...

Electric Vehicle Battery Technologies

As discussed in the previous chapter, electrification is the most viable way to achieve clean and efficient transportation that is crucial to the sustainable development of the whole world. In the near future, electric vehicles (EVs) including hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and pure battery electric vehicles (BEVs) will dominate the clean vehicle mark...

Numerical investigation of the parameters of a prismatic lithium ion battery under load for electrical vehicle

Electric vehicles and hybrid electric vehicles are a suitable alternative for vehicles with hydrocarbons fuels to reduce pollution and fossil resources. The batteries operate as the driving force for these vehicles. One of the most critical parameters of the battery is computing the state of charge (SOC). The best range for SOC of lithium-ion battery is between 20% and 90%, and charging and dis...

Multi-Scale Parameter Identification of Lithium-Ion Battery Electric Models Using a PSO-LM Algorithm

This paper proposes a multi-scale parameter identification algorithm for the lithium-ion battery (LIB) electric model by using a combination of particle swarm optimization (PSO) and Levenberg-Marquardt (LM) algorithms. Two-dimensional Poisson equations with unknown parameters are used to describe the potential and current density distribution (PDD) of the positive and negative electrodes in the...
