DandeLiion v1: An Extremely Fast Solver for the Newman Model of Lithium-Ion Battery (Dis)charge

نویسندگان

چکیده

DandeLiion (available at dandeliion.com) is a robust and extremely fast solver for the Doyle Fuller Newman (DFN) model, standard electrochemical model (dis)charge of planar lithium-ion cell. conserves lithium, uses second order spatial discretisation method (enabling accurate computations using relatively coarse discretisations) many times faster than its competitors. The code can be used "in cloud" does not require installation before use. difference in compute time between commercial counterparts roughly factor 100 moderately-sized test case discharge single Its linear scaling property means that disparity performance even more pronounced bigger systems, making it particularly suitable applications involving multiple coupled cells. characterised by number phenomenological parameters functions, which may either provided user or chosen from DandeLiion's library. This library contains data most commonly electrolyte (LiPF6) common active material chemistries including graphite, lithium iron phosphate (LFP), nickel cobalt aluminum (NCA), variant manganese (NMC).

An Adaptable Lithium-Ion Battery Model

We present here a complete model of a Sony 18650HC lithium-ion battery developed in MATLAB/Simulink, which is adaptable to other lithium-ion cell chemistries and can be implemented into a full power system model. The model accounts for varying current rates, temperature dependencies and internal cell characteristics under both charge and discharge conditions and is primarily based on characteri...

Micrometric Growth of V2O5Hexagonal Nano-plates as an Active Material for Lithium Ion Battery Cathode Electrode

This manuscript reports the synthesis of V2O5 nanostructures using reflux method, without using additives such as surface reactants. The influence of reaction parameters like temperature and concentration on the growth of nanostructures have been investigated. It has been observed that the nanostructures are formed with a hexagonal nano-plate morphology, grown from a common core. The diameter o...

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...
