A HEV(Hybrid Electric Vehicle) refers to a Hybrid Electric Vehicle, while PHEV(Plug-in hybrid electric vehicle) refers to a plug-in hybrid electric vehicle. The two are not absolutely good or bad, mainly depending on your use needs and charging conditions.
1. HEV: The battery capacity of hybrid electric vehicles is small, usually only provides a part or a small part of the driving needs, most of the power still comes from the engine. The advantage of this model is that the energy saving effect is obvious, but the disadvantage is that it cannot achieve zero-emission driving over long distances.
2. PHEV: The battery capacity of plug-in hybrid electric vehicles is large, which can support the vehicle to travel a long distance, and even achieve pure electric drive. The advantage of this model is the greater ability to achieve zero-emission driving, while also reducing fuel consumption. However, due to the increase in battery capacity, the purchase cost and maintenance cost are relatively high.
In general, if you have a short daily commute and a charging station at home, then a PHEV may be more suitable for you; If your travel needs are more complex, including long-distance driving, then HEV may be more practical.
