	\includegraphics[width=\textwidth]{./bilder/output.pdf}
	\caption{Schematic of BSPD}
\end{figure}

The BSPD PCB is located in the front "Sensor-Node" (mainly there to transfer the analog data to CAN), in which a separate compartment is created to ensure the BSPD can be separated sealed without affecting other parts in the same housing.

\begin{multicols}{2}
	\textbf{Test Procedure}
	\begin{enumerate}
		\item apply external test current to the simulation coil
		\item brake hard (with brake pressure $\geq 30 \unit{\bar}$)
	\end{enumerate}
	
	\textbf{Test Current Calculation}
	\begin{align*}
		I_{test} &amp; = 5 \unit{kW} / V_{max} = 5 \unit{kW} / 403.2 \unit{V} \\
		         &amp; = 12.401 \unit{A}
	\end{align*}
	\quad \quad 12 windings $\longrightarrow$ test current $\approx 1.034 \unit{A}$
\end{multicols}
