The ECVT
......
it is often referred to by
its new name: Power Split Device.

That says it all. They have put a fancy acronym to the power splitter. The
power splitter does not, input - raise or lower ratios - output; it take
two parallel power sources and combines them into one sending the combined
power to the wheels.

The only thing that is Continually Variable is the ratio of the two power
inputs, The management system decides what level of electric to petrol
motor power to combine to output to the wheels. That is "very", "very",
different to a stepless CVT that are quite common in other conventional
cars.
