Current Consumption
\section*{Current Consumption}
To calculate the current consumption, the load on the shutdown circuit must first be identified. As seen in the SDC schematic, the load consists of the AIRs, precharge relay, EBS Relay and the Discharge Circuit.
The current consumption of the components are as follows:
%\begin{figure}[H]
% \centering
% \includegraphics[height=\textheight]{./Documents/Master_FT25-SDC_Latching.pdf}
% \caption{Schematic of the Shutdown Circuit Latching }
%\end{figure}
\begin{multicols}{2}
\begin{itemize}
\item AIRs: \SI{249}{\milli\ampere}
\item Precharge relay: \SI{8}{\milli\ampere}
\item EBS relay: \SI{9.6}{\milli\ampere}
\item Discharge circuit: \SI{4}{\milli\ampere}
\end{itemize}
\end{multicols}
%\begin{figure}[H]
% \centering
% \includegraphics[height=\textheight]{./Documents/SDC.pdf}
% \caption{Schematic of the Shutdown Circuit}
%\end{figure}
We can then find the total consumption when we add all the the load together. $\SI{249}{\milli\ampere} \cdot 2 + \SI{8}{\milli\ampere} + \SI{9.6}{\milli\ampere} + \SI{4}{\milli\ampere} \approx \SI{520}{\milli\ampere}$.
