The difference between hybrid and oil electric hybrid is as follows:
1. Working principle:
Hybrid vehicle: It adopts a dual power system of internal combustion engine and electric motor, which can work separately or simultaneously and are intelligently managed by the electronic control system. Electric motors are usually powered by batteries, while internal combustion engines use traditional gasoline or diesel fuels.
Oil electric hybrid vehicle: Both internal combustion engine and electric motor power systems are used, but the electric motor can only work together with the internal combustion engine and cannot independently drive the vehicle. Electric motors are mainly responsible for assisting internal combustion engines, providing additional torque in situations that require significant power output such as starting, accelerating, or climbing.
2. Power output and user experience:
Hybrid vehicles: Electric motors are usually small and have low power, mainly used for auxiliary driving to reduce fuel consumption of internal combustion engines. Some hybrid vehicles support pure electric mode, which can rely entirely on the electric motor for power supply during short distance driving, further reducing exhaust emissions and fuel consumption. It is quieter and smoother when driving at low speeds and on urban roads, with no exhaust emissions; When driving at high speeds or requiring significant power, the internal combustion engine will take over the drive.
Hybrid electric vehicle: The electric motor has relatively high power and can provide stronger auxiliary driving force to help the internal combustion engine achieve more efficient operation, but it cannot be driven in pure electric mode. Always relying on internal combustion engines for power output, electric motors and internal combustion engines work closely together to provide vehicles with more stable and smooth power output.
3. Battery capacity, materials, and charging methods:
Plug in hybrid: The battery has a large capacity and can store more than 10 degrees of electricity, usually using lithium batteries. It requires external charging to drive and can fully rely on electric energy to drive the vehicle within a certain range, belonging to new energy vehicles.
Hybrid models: The battery capacity is small and can only store one or two kWh of electricity, usually using nickel hydrogen batteries. It can automatically charge during driving without the need for external charging devices. It belongs to energy-saving fuel vehicles and cannot be charged through external power sources.
There are also differences between hybrid and oil electric hybrid in terms of launch time, price, and environmental performance. Hybrid cars place more emphasis on fuel economy and environmental performance, while hybrid models focus more on providing higher power output and driving performance.
