What does plug-in mean?
1 Answers
Plug-in is a type of vehicle propulsion system. Plug-in vehicles can use a plug to connect to a regular power source to charge the battery, and are equipped with both an electric motor and an engine. Below is relevant information about plug-in hybrid electric vehicles: Series plug-in hybrid electric vehicles: Also known as range-extended electric vehicles. The engine does not directly drive the vehicle; instead, it first drives a generator to produce electricity, which then powers the electric motor to drive the vehicle. This results in a longer energy transfer chain and relatively lower overall efficiency. Parallel plug-in hybrid electric vehicles: In this type, both the engine and the electric motor can drive the vehicle. It offers multiple power transmission modes, better dynamic performance, a simpler structure, and is widely used, making it the mainstream technical route. Power-split plug-in hybrid electric vehicles: Also known as series-parallel hybrids. They typically require two motors (one generator and one electric motor) and a planetary gear set for power splitting.
