How does it work?

At peak boost a typical turbocharger is capable of pumping around 170 litres of air per second, which requires a serious amount of energy. For turbochargers, the waste energy in a combustion engine’s exhaust is the perfect source; however the electric motor’s appetite for an equivalent amount of power would easily overwhelm a conventional 12-volt system.

To meet the electrical demand, a special 48-volt sub-system is employed. The separate battery is topped up graduallyally from the 12-volt system via a converter and, just like an electricectric vehicle’s battery, the higher voltage unit can dispense energygy faster than a regular car battery.ry. The 48V system has the grunt to spin the electric powered compressor to maximum boost in just 250 milliseconds.
