The paper describes the development and realization of standard battery modules 12 V, made by LiFePO4 cells selected in a previous study by ENEA and the University of Pisa. Module means the group of four cells series connected, the electronic battery...

Since a laptop caught fire in 2006 at the latest, Li-ion cells were considered as more dangerous than other accumulators [1]. Recent incidents, such as the one involving a BYD e6 electric taxi [2] or the Boeing Dreamliner [3], give rise to questions...

Thermal impedance spectroscopy (TIS) is a non-destructive method for characterizing thermal properties of entire battery cells. Heat capacity, thermal conductivity and heat exchange with environment are deter-mined by an evaluation of the heat transf...

The decision to select the most suitable type of energy storage system for an electric vehicle is always difficult, since many conditionings must be taken into account. Sometimes, this study can be made by means of complex mathematical models which r...

As a key issue in EVs (Electric Vehicles) development, Li-ion battery’s thermal safety is focused on in which the thermal abuse model is an important tool. This paper has established a 3-D electro-thermal model taking side reaction into account, in o...

This paper discusses the model simplifing issue in battery thermal simulation. The paper verifies that for the large power battery simplifying the multilayer battery core as a lumped cuboid is reasonable. So when doing simulation, building a multilay...

Hybrid Energy Storage System (HESS), which combines the battery and supercapacitor (SC), is a potential solution for the energy system of Electric Vehicles (EV). In this paper, a battery and SC hybrid system for small-scale EV with Energy Management...

Thermal impedance spectroscopy (TIS) is applied for the thermal characterization of a large prismatic battery cell. The method is based on previously published work and is extended to a three dimensional system. By using a discretized three dimension...

One of the most relevant tasks that must be carried out by a Battery Management System (BMS) is the diagnosis of the battery state. An important part of the algorithms used for determining the State of Charge (SOC) or the State of Health (SOH) requir...

High power lithium iron phosphate (LFP) batteries suitable for Electric Vehicles are tested in this work. An extended cycle-life testing is carried out, consisting in various types of experiments: standard cycling, optimized fast charge with high con...
