Week 5 Battery characteristics using drive cycle
Problem Statement -
Simulate generic battery model charge discharge using UDDS data.
Model -

The model shows a high volatge circuit that can be used for an electric vehicle. The load current is given by a current profile which is derived from a drive cycle. As per the current profile the total simulation time is 1371 seconds. The values of time and current are copied from an excel sheet and arrays are created in MATLAB which are then called at the signal builder to create this current profile -

The battery parameters are as follows -

The battery acts as a signal for the constant current source which should face downward while observing discharge characteristics. This is connected to the battery through a current sensor. The battery outputs the SOC%, Voltage and current drawn or charged. This can be compared with our reference current profile from the current sensor at the scope -

The battery output and our reference current profiles math and the final value of SOC is close to 99.5%.
