A series hybrid electric vehicle (SHEV) is a type of hybrid car that utilizes two power sources: an internal combustion engine (ICE) and an electric motor. The ICE generates electricity to charge the battery pack, which in turn powers the electric motor to propel the vehicle. The main components of a series hybrid electric vehicle include the ICE, battery pack, and electric motor. The working process of a series hybrid electric vehicle involves starting the vehicle with the electric motor drawing power from the battery pack, driving at low speeds or during city driving using only the electric motor, increasing speed or accelerating by starting up the ICE to generate electricity and charge the battery pack, regenerative braking to convert kinetic energy into electrical energy and store it in the battery pack, charging the battery pack when its state of charge falls below a certain level, steady-state driving on highways with the ICE running at its optimal speed while the electric motor provides necessary power, and shutting down both the ICE and electric motor when the vehicle is turned off. Series hybrid electric vehicles offer benefits such as improved fuel efficiency, lower emissions, reduced wear and tear on the ICE, and regenerative braking.
Parallel hybrid electric vehicles (PHEVs) are a type of hybrid vehicle that combines an internal combustion engine (ICE) with an electric motor. The two power sources can work independently or together, depending on the driving conditions. PHEVs have three operating modes: ICE only, electric motor only, and combined power. The energy management system controls the operation of the ICE and electric motor, deciding which power source to use based on driving conditions, battery state of charge, and other factors. PHEVs offer benefits such as improved fuel efficiency, reduced emissions, tax incentives, and reduced dependence on fossil fuels.
Key components of a series hybrid electric vehicle (SHEV) include the battery pack, electric motor, internal combustion engine (ICE), generator, transmission, control unit, and regenerative braking system. The battery pack stores energy from the ICE or regenerative braking system and provides it to the electric motor when needed. The electric motor drives the wheels of the vehicle, while the ICE generates electricity to charge the battery pack rather than directly powering the wheels. The generator converts mechanical energy from the ICE into electrical energy to charge the battery pack. The transmission transfers power from the electric motor to the wheels using a single-speed reduction gearbox. The control unit manages the flow of energy between the various components and optimizes their operation. Finally, the regenerative braking system captures energy lost during braking and uses it to recharge the battery pack, increasing fuel efficiency and extending the range of the vehicle.
