Level 1 or Level 2 AC (alternating current) voltage is sent through the motorcycle's power receptacle (vehicle inlet) with the supplied EVSE (electric vehicle supply equipment) to the onboard charger (OBC). The OBC is then responsible for converting the AC to DC (direct current) which is used to charge the RESS (rechargeable energy storage system). The RESS sends the DC power to the EVPT (electric vehicle power train) where the ePTC (electric powertrain control) sends low voltage control signals to the MCM (motor control module). The MCM converts the DC to 3-phase AC which power's the AC permanent magnet motor to provide propulsion to the motorcycle. During deceleration, varying levels of regenerative braking is applied through the EVPT (user adjustable or predefined ride modes) and converted to energy that is used to recharge the RESS. This energy is converted from the AC generated by the motor to DC within the ePTC and then is sent back to the RESS.
During Level 3 or DC fast charge, the DC voltage is sent directly from the DC charging station through the power receptacle's DC positive and negative leads which go directly to the RESS. The OBC controls the DC fast charge rate by communicating with the charging station, governing the charge rate of the fast charger in order to recharge the RESS.
