What is the difference between PHEV and MHEV?
2 Answers
The differences between PHEV and MHEV are: 1. Different vehicle types: PHEV is a plug-in hybrid model; MHEV is a mild hybrid model. 2. Different charging methods: PHEV plug-in hybrid vehicles require both refueling and charging; MHEV hybrid vehicles only need refueling. 3. Different license plate policies: PHEV plug-in hybrids can get new energy green license plates; MHEV hybrids cannot get green plates. PHEV and MHEV are two mainstream types of new energy vehicles in China, and their main functions can significantly reduce pollutant emissions and lower vehicle fuel consumption.
I've always been very interested in new energy vehicles, and there are actually significant differences between Plug-in Hybrid Electric Vehicles (PHEVs) and Mild Hybrid Electric Vehicles (MHEVs). PHEVs can be charged like electric vehicles, with large battery capacities that allow them to travel dozens of kilometers in pure electric mode, making them ideal for daily short commutes; the gasoline engine only kicks in after the battery is depleted. As for MHEVs, they cannot be charged externally and have smaller batteries primarily used to assist the engine, such as recovering energy during braking to help with acceleration or reducing idle fuel consumption—essentially still relying on traditional fuel systems. Driving a PHEV in pure electric mode feels quiet and smooth, much like driving an electric car; driving an MHEV is like driving an upgraded gasoline car, with slightly lower fuel consumption but nothing particularly novel. In terms of choice, if you have a home charging station or can charge at work, a PHEV is more fuel-efficient and eco-friendly; without charging access, an MHEV is more convenient as you don’t have to worry about charging, though its environmental benefits are weaker. Based on my personal experience, PHEVs are better suited for urban commuters, while MHEVs are ideal for long-distance road trip enthusiasts.
