Electric drive with dual-energy storage and variable inverter input

An electric vehicle comprising:

• an electric drive system comprising:
• a first electric drive;
• a second electric drive;
• a switchable battery including at least two battery packs that are selectively arranged in one of a series configuration and a parallel configuration;
• a first half-bridge buck converter connecting the first electric drive to a first battery back of the at least two battery packs of the switchable battery;
• a second half-bridge buck converter connecting the second electric drive to a second battery back of the at least two battery packs of the switchable battery;
• and
• a controller configured to control a configuration of the switchable battery, an operation of the first half-bridge buck converter, and the second half-bridge buck converter.

• and
• a controller configured to control a configuration of the switchable battery, an operation of the first half-bridge buck converter, and the second half-bridge buck converter,
• wherein the controller configures the at least two battery packs in parallel based at least in part on a rotational speed of one or more of the first electric drive and the second electric drive being below a first threshold level and configures the at least two battery packs in series based at least in part on a rotational speed of one or more of the first electric drive and the second electric drive being above a second threshold level.
