Week 5 Battery characteristics using drive cycle

Aim:

To Simulate generic battery model charge discharge using UDDS data.

Procedure:

* UDDS Drive cycle:

Simulink Model:

i) Signal builder:

* The Signal builder displays,creates,edits the interchangable scenarios.

* The Signal builder supports the MAT files that contains one or more data projects.

* By Using this Block, we can give UDDS cycle, which is being imported and given as Input

ii) Controlled Current Source:

* The Controlled Current Source controls the Simulink input signal to an equivalent current source.

* The generated current is driven by input signal of the block.

* You can initialize the Controlled with the AC or DC current.

iii) Generic Battery Source:

This represents that the generic dynamic model that represents the most types of rechargeable batteries.

iv) Bus Selector:

* The bus selector outputs the element which is selected from the input bus.

* The block output can be selected elements that can be separately in a new virtual bus.

v) Scope:

* The scope displays its inputs with respect to simulation time.

* The scope block can have multiple axes, which are independent to the y-axes.

* Allows to display and adjust the amount of time amd range of input values displayed.

vi) Power gui:

* The powergui block is necessary for simulation of any SIMULATION block of any Simulink model containing SimPowerSystems blocks.

* Used to store the Simulink circuit that represent the state-space equation of the model.

Observation:

* From this scope, the Battery SOC is becoming up and down, according to the charging and discharging of the battery.

* The negative current means the charging and the positive current means discharging in the terms of battery.

Result:

The Simulation of generic battery model charge discharge using UDDS data has been done, using SIMULINK software.
