The system is controlled by an advanced Electronic Control Unit (ECU), which calculates the most efficient use of the available energy, and adjusts accordingly, taking into account the amount of charge remaining in the car’s batteries. Charge from the 48V battery helps to start the engine in most conditions.

At 48 volts, a VTES electric supercharger will transform 7kW of battery power into a highly boosted charge of air for downsized gasoline and diesel engines. There will be no torque deficit or other tradeoffs from essential engine downsizing and higher gearing, which now dominates the development of internal combustion engines.
