Power systems and methods for electric vehicles

Abstract:

Embodiments include a junction box for an electric vehicle. The junction box includes a charging port to receive power from an external power source, and a plurality of switching elements to control electrical connections between the charging port, a first battery, and a second battery. On/off states of the plurality of switching elements control whether the charging port, the first battery and the second battery are connected in a first configuration or a second configuration.
