Can a Plug-in Hybrid Be Charged by the Engine?

[DelThomas]

The engine of a plug-in hybrid vehicle cannot directly charge the battery, as it may affect the battery's lifespan and performance. However, some energy recovery devices can charge the battery. Therefore, when the power battery is low, it must be charged externally. Advantages and disadvantages of plug-in hybrid vehicles: 1. Compared with non-plug-in hybrid vehicles: Plug-in hybrids have larger battery capacities, which can support longer driving ranges. If the vehicle is only used for short trips and has good charging conditions, a plug-in hybrid can operate without refueling, functioning like a pure electric vehicle and offering the same advantages. 2. Compared with pure electric vehicles: Plug-in hybrids have much smaller battery capacities. However, they are equipped with traditional fuel vehicle components such as an engine, transmission, drivetrain, fuel system, and fuel tank. Thus, when charging is unavailable, the vehicle can continue driving as long as there are gas stations, with the driving range not limited by charging conditions.
