Question

which type of vehicle uses a 48 - volt lithium ion battery?
a) battery electric vehicle (bev)
b) plug - in hybrid electrical vehicle (phev)
c) mild hybrid electric vehicle (mhev)
d) all of the above

Explanation:

A 48 - volt lithium - ion battery is typically used in Mild Hybrid Electric Vehicles (mHEV). Battery Electric Vehicles (BEV) usually have higher - voltage battery systems (e.g., hundreds of volts) to power the main electric motor for full - electric propulsion. Plug - in Hybrid Electrical Vehicles (PHEV) also have higher - capacity and higher - voltage battery systems (often in the range of hundreds of volts) to support both electric - only driving (for a certain range) and hybrid operation. Mild Hybrid Electric Vehicles (mHEV) use a 48 - volt system mainly for functions like assisting the internal combustion engine (e.g., during acceleration), regenerative braking, and powering ancillary systems.

Answer:

C) Mild Hybrid Electric Vehicle (mHEV)
