The main differences between HEV and PHEV are as follows:
- Charging method: HEV cannot be charged externally, but relies on the engine and energy recovery to charge; PHEV can be charged externally, and the battery capacity is larger.
- Endurance: The pure electric endurance of HEV is generally less than 5 kilometers, mainly used for auxiliary; the pure electric endurance of PHEV is generally more than 50 kilometers, and some new models can reach 200 kilometers.
- Policy treatment: PHEV is a new energy vehicle, enjoying green license plate, purchase tax exemption and other policies; HEV is classified as a fuel vehicle, without relevant discounts.
- Driving logic: HEV is mainly fuel-driven, with motor assistance; PHEV can be driven purely by electricity for short distances, and oil and electricity can be coordinated for long distances.
Long-distance driving suggestions:
If you often travel long distances and have no charging conditions, HEV is more suitable. Its advantages are:
- No need to charge, just refuel and go
- Stable fuel consumption under high-speed conditions (such as Camry Hybrid about 4.5L/100km)
- Mature technology, low failure rate
If the long-distance frequency is low and charging conditions are available, plug-in hybrid is more economical. For example: - Daily commuting in pure electric mode (electricity cost about 0.1 yuan per kilometer)
- New plug-in hybrids such as BYD Song L DM-i have a comprehensive range of 1,500 kilometers and a fuel consumption of 3.9L/100km when the battery is depleted
- In 2025, some plug-in hybrid models have optimized high-speed fuel consumption performance through technical upgrades
