Lithium Battery Model with Thermal Effects for System Level Analysis

[@shikharsaraswat410]

Amazing approach and a great video 👍🏼👍🏼

[@ridaelchami4011]

where have we used the CC discharge test data in the model ? why we should make this test ? the HPPC test is not sufficient ? the SOC and the usable capacity are estimated in the program or in real test ?

[@hassancheaito3598]

Hi Rida, I think they use CC discharge to simply make their look-up table @ different SOC. Therefore, the SOC is estimated by experiment first and then they try to fit the program with real results. BR

Please how could i get this model?

[@veeramanikandan198]

Whether we have to set soc as output in Em-look up table

[@bothug4981]

It‘s very very good job. Thanks!

[@abdullahmohamed4330]

could you please explain to me how he estimated the lookup table from SOC?

I have a schematic for a 48 voltage DC charger, I want to apply it to Matlab. This circuit consists of a three-phase AC voltage source , a step-down transformer, a conduction group YnD11, and then a rectifier circuit consisting of a thyristor (6) thyristor and connected in series with it a coil and then the load is a resistance and connected to it a capacitor in parallel. I want to get a voltage so that I can charge the lithium battery its voltage 48VDC. Forgive me for being so long, and I hope you can help me. Thanks

How can we choose the best equivalent circuit for our battery ? if I need to capture a high current transients from regenerative braking into a battery. How to choose the adaptable model ?

[@hassancheaito3598]

Again Rida, I have a little bit experience in modeling of batteries. I think there is no 'one' best equivalent circuit. It depends on what you search, how much precision is important, what tools you have (impedance analyzer, load, tank for temperature..). Many are the parameters to monitor. If I understood your need (just the transient), then I think that you don't need the SOC and temperarture involvement. Try just with internal resistance, you will have the most quick model, then for more precision add RC network in series. Besides, I liked your videos about 'sfouf' !

[@ridaelchami4011]

@@hassancheaito3598 Thank you for your reply. I am searching now for a model which represent the behavior of the electrochemical process inside the battery. this will take some time to better understand the topic. Don't forget to try the sfouf 😀😀👍

@@ridaelchami4011 I will ;)** unfortunately I don't have a big experience in electrochemical modeling..however I'm interested in your application, if you need information about aging and electrical performance about different lithium ion technologies u can contact me [e-mail]

Which equation is used for capacitor look up table

[@selee006]

Could any one here give me a link to a file "ssc_lithium_cell_1RC_estim.slx?

[@oussamasadki6788]

Tap down the command 'ssc_lithium_cell_1RC' in matlab command window

[@ridaelchami4011]

why you never reply to comments ?

[@sanketajmire2766]

Is there any drawback of using the RC model for battery modeling in MATLAB?

[@KraulG]

For simplified simulation it is better to use free-of-charge LTspice like this kzbin.info/www/bejne/a6vEeYuAoL-tgtU

excellent!

Great Video, I wana be good at this
