Engine Starter
A pulley on the end of the engine crankshaft connects the engine to a Hybrid Starter Generator (HSG) via a reinforced plastic belt which serves a dual role, unlike conventional cars which have a separate starter motor and alternator. It can potentially be part of the regenerative braking process and is used to start the engine when the car is stationery. On the move, the engine is bump started through the transmission. (I have seen another source claim that the engine is started by the starter motor and brought up to speed before engaging with the transmission via a clutch)
The drive belt has a service life of between 40,000 and 70,000 miles which varies with each market.
DCT 6 Speed Gearbox
Wear of the DCT clutch plates is minimised in two ways. There is no clutch action involved when starting from a stop. That's done by the electrical motor whilst the clutch is fully engaged in first gear. This is normally the main source of wear and the main source of annoyance with DCT transmission (the infamous slight shuddering feeling at low speeds). The DCT clutches are under very little stress because the electric motor is effectively a torque converter and always gets the car underway from stationary.
Any gear changes once driving should not put too much strain on the clutches because the engine isn't all that powerful and the ECU and gearbox controls try to match the speed of the engine to the speed of the input shaft of the gearbox to minimise wear, Hyundai/KIA have ensured this by adopting a powerful central processor that is fast enough to manage a quick and smooth clutch lockup. The lockup takes just 0.6 seconds.
Hybrid Battery
All three versions of the Niro will use lithium polymer batteries made by South Korean supplier LG Chemicals. KIA claim that the polymer structure is safer than the traditional lithium ion batteries used by some rivals.
This type of cell/battery scores high in max current (amps), safety (250oC thermal runaway - does not easily catch fire), life span (1000 - 2000 cycles), low cost to produce, and scores particularly well in capacity (how much power it will hold). They are good all round cells.
O sea, que el desgaste del embrague debe de ser mínimo porque el Niro equipa un sistema que hace que
1º) inicie la marcha en eléctrico, sin rozamiento ni desgaste alguno y
2º) cuando el motor térmico es necesario se sincroniza en vueltas con el embrague
