A Power Buffer in an Electric Driveline: Two Batteries Are Better Than One

Figure 9

Power delivered to the wheels (blue) by the battery (green) and the power buffer (red) during the EPA FTP-75 standard drive cycle. The battery is rated 4.8 kW and a power buffer limited to 0.25 kWh. The battery and the power buffer are capable to follow the power demand, so the power mismatch is zero. The integral of this mismatch is the energy mismatch presented in Figure 8.
