Hi I'm Rofiq

I'm doing project in simulink which doing battery simulation with equation for example x(k+1)=x(k)+P(k) where x(k+1) is the energy stored in battery at time k+1 that is equal to energy stored in battery at time k plus/minus amount energy that charge/discharge to or from battery at time k

What block I should use to build above simulation, I need some block that can store my input value at time k (charging phenomena) and then use/retrieve it at another time k+10 (discharging phenomena). This block/variable act like battery which can inform how much energy stored at time instance and also increase/ decrease over sample time

Thank you for the help

You can use unit delay block

Tapped Delay block could help you on this. It stores all previous values of how much delay you set in the block...It will store it in a vector format and at last you can access it altogether at once.
