A Range Extended Electric Vehicle (REEV) is a vehicle that combines an electric vehicle with a fuel generator. It works by using an electric motor to drive the vehicle and a fuel generator to charge the battery, thus extending the range of the electric vehicle.
Advantages of the add-on vehicle
Increased range: add-on cars are equipped with a small fuel engine that provides energy to charge the electric car, extending the range in electric mode. This means that an add-on vehicle has a longer range compared to a pure electric vehicle, reduces reliance on charging facilities, and allows for easier long-distance travel.
Reduced Range Anxiety: Since the add-on vehicle has a fuel engine as a backup energy source, drivers don't have to worry about running out of battery power. Even if the battery is low, the fuel engine can provide charging for the EV, giving drivers more peace of mind and reassurance.
More energy-efficient and environmentally friendly: Compared with traditional fuel vehicles, the Programmable Vehicle relies mainly on electric drive in daily driving, which reduces exhaust emissions and environmental pollution. At the same time, the programmable vehicle can also automatically choose to run in electric mode or fuel mode according to driving conditions and vehicle load, etc., in order to achieve the best energy utilization efficiency.
Driving Flexibility: The add-on vehicle can not only run in electric mode, but also continue to run in fuel mode. This allows drivers to choose to use electric drive or fuel drive according to their needs and actual situation, increasing driving flexibility and selectivity.
Convenient charging facilities: Although charging facilities for plug-in hybrids are not as common as for pure electric vehicles, the Plus Program Vehicle can recharge itself via the fuel engine when needed, without the need for charging posts. This provides drivers with more convenient charging options and reduces reliance on charging facilities.
Disadvantages of add-on vehicles
Higher Cost: Add-on cars are more costly as compared to conventional fuel cars and electric cars in general. This is mainly due to the need for an additional fuel engine and associated systems. As a result, add-on vehicles usually cost more to purchase and may put some financial pressure on consumers.
Higher weight: Since a Programmable Vehicle requires both an electric drive system and a fuel engine, its overall weight is usually higher. This can result in a slightly less energy-efficient add-on vehicle, and can have an impact on suspension and handling.
Fuel Dependency: Even though a programmable vehicle is equipped with a fuel engine as a back-up energy source, relying on fuel drive for extended periods of time can increase fuel consumption and emissions. This is a constraint on reducing dependence on the use of conventional fuel and achieving more environmentally friendly goals compared to pure electric vehicles.
Longer charging time: Although the add-on vehicle has a range in electric mode, it needs to use the fuel engine as a back-up energy source or to recharge when the battery is depleted. Compared with pure electric vehicles, the charging time for add-on vehicles is usually longer, and it takes a longer time to be fully charged.
Restricted interior space: Since a programmable vehicle requires the placement of an additional fuel engine and related systems in the vehicle, interior space is somewhat limited. This may affect the comfort and utility of the ride and storage space.
