OBJECTIVE;

For a 10 cell series, calculate the voltage, current and SOC. Also simulate the aging and thermal effects at different charge and discharge rates using Matlab

MODEL;

• Now a days lithium ion battery are mostly used in electric vehicles we must know its charge and discharge rates to operate this batterys in efficient manner and with out damage when this batterys in operation this temperature of it must be kept in limit we simulate the thermal effect of this cell , by knowing the how much temp rise take place we can provide efficient cooling to the batterys so that the life cycle of the battery increases we will see a model on this issue below and explaination as follows
• cells connected in series and one of the cell is faulty so what will be thermal effect .
• This example shows how to simulate a battery pack consisting of multiple series-connected cells in an efficient manner.
• It also shows how a fault can be introduced into one of the cells to see the impact on battery performance and cell temperatures

THESE BLOCKS ARE USEDIN MODEL;

• Battery
• Voltage measurment
• Constant
• Scope
• Gain
• Current Measurement
• powergui
• Controlled Currenrt source
• Sum

• Controlled Current Source for Discharge the battery with some constant discharge current
• Scope for output waveform
