Parallel hybrid configuration Parallel hybrid configuration | Source: Sciencedirect Also, production hybrids are relatively efficient in city driving with frequent stops. That is, the internal combustion engine can operate in a narrow rpm range most efficient range even when the vehicle is changing speed.

The simplicity of operation and no complicated transmission.it takes a certain time to charge from a working internal combustion engine. The impossibility of movement in case of complete discharge of the battery.Inability to achieve the addition of the powers of the alternative drive motors.Low efficiency of the mechanism for transferring energy from the internal combustion engine to the driving wheels of the vehicle then it is a during long-distance highway driving, the overall efficiency is lower than that of a conventional transmission due to several energy conversions.Consequently, the overall weight, cost, and size of the drivetrain can be prohibitive.

The advantages of individual wheel motors include simplified traction control no traditional mechanical transmission elements such as a gearbox, transmission shafts, differential Some 8×8 and 4х4 military vehicles use individual motors.īy the way, a hybrid fuel cell vehicle always has a series configuration the engine-generator combination is replaced by a fuel cell. Integration of the engine into the wheels has the disadvantage of increasing the unsprung mass, which reduces driving performance. Some vehicle designs have separate electric motors for each wheel. Conversely, series hybrids are more efficient for driving in the city because their drivetrain structure reduces the strain on the engine in stop-and-go driving situations.This solution results in a less deep discharge of the battery and the stress factor of the battery. According to Hybrid Center, the composition of parallel hybrids makes them more efficient for highway driving at higher, more constant speeds. The efficiency of parallel and series hybrids varies according to the conditions under which they're driven.

The energy that is released from the wheels turns the electric motor, which acts as a generator and sends electricity back to the battery. In a regenerative braking system, the electric motor helps to slow the car down as you press the brake, according to the U.S. A controller in the transmission determines how much power is needed to propel the vehicle and whether to pull it from the battery or the generator.īoth parallel and series hybrids feature a regenerative braking system, which both slows the car and recharges the battery. The gasoline engine in a series hybrid is not coupled to the wheels and does not directly power the car. According to Hybrid Center, the electric motor is charged by the battery pack or by the generator, which is powered by the gasoline engine. In a series hybrid, the electric motor is solely responsible for turning the vehicle's wheels. A controller in the transmission determines when to operate the electric motor and when to switch to the gasoline engine. When fuel travels to the engine or when the electric motor is turned on, the power that is generated propels the car. Department of Energy (DOE), the gasoline engine and the electric motor are both connected to the transmission. In a parallel hybrid, both the electric motor and the combustion engine work together to power the vehicle. In a series hybrid, the gasoline engine is not coupled directly to the wheels, while it is in a parallel hybrid. In a parallel hybrid, the electric motor acts as a generator. Series hybrids feature a separate generator which is connected to the engine. According to Hybrid Center, the engine in a series hybrid is smaller than a parallel hybrid while the electric motor and battery are larger. While both parallel and series hybrids feature a gasoline engine, electric motor, rechargeable battery, inverter and transmission, they are configured in uniquely different ways.
