An EREV is a Series-Hybrid. EREV is a marketing name conjured up because most non-technical people don't understand there are two types of hybrid vehicles: Parallell Hybrid (i.e. Prius) and Series Hybrid (i.e. Volt* or BMW i3).
*the Volt was unique in that its transmission could switch to parallel hybrid operation under specific circumstances.
Hybrids are divided into two architectures: (a) Parallel Hybrid and (b) Series Hybrid.
Parallel Hybrid means the gas motor (it can be gasoline or diesel) runs in parallel with the electric drivetrain to power the electric motors and charge the battery and has a mechanical connection to the road wheels. There are several sub-variations of the Parallell hybrid system.
Series Hybrid means the gas engine operates to create electricity that powers the electric drive motors and charge the battery. The gas engine is not mechanically connected to the road wheels. It's called "series" because the engine-powered electric generator has to make electricity first before the car will move. Make electricity first means the generator either supplies the electric drive motors with power or charges the battery, or both.
It appears the Harvester architecture will also be a PHEV (Plug-in Hybrid Electric Vehicle), which means it can be plugged in to a charger to charge the battery in advance of the engine-generator supplying power to the electric drivetrain. Once the battery reaches a predetermined level of energy depletion the engine-generator starts and begins powering the electric drivetrain.
