Equations

Traction battery stored energy Equation (1):

(1)\[ \begin{align}\begin{aligned}Given:\\byteF &= E6_{16} = 123_{10}\\Then:\\E_{stored} &= byteF_{10} \cdot 80_{10}\ W \mathord{\cdot} h\\&= 123_{10} \cdot 80_{10}\ W \mathord{\cdot} h\\&= 9840_{10}\ W \mathord{\cdot} h\end{aligned}\end{align} \]

Traction battery state of health (SoH) Equation (2):

(2)\[ \begin{align}\begin{aligned}Given:\\byteB &= A2_{16} = 10100010_{2}\\Then:\\SoH &= byteB_{2} >> 1\\&= 10100010_{2} >> 1\\&= 01010001_{2}\\&= 81_{10} \%\end{aligned}\end{align} \]
