With the invention of the first electric car in 1837 by chemist Robert Davidson of Aberdeen, there was the hope for cleaner transport system. The electric vehicle used power from galvanic cells or batteries. He later in 1841 advanced to a seven-ton vehicle that used two direct reluctant motors. The two motors had more energy than galvanic cells. The electric vehicle would move at a speed of four miles per hour. Electric vehicles were very common in 18th and 19th century. Most people found them convenient
Literature 2.1.1 Electric Vehicle Figure 2.1 shows a block diagram of an electric vehicle. It contains a battery that supplies energy, an electric motor that drives the wheels, and a controller that regulates the energy flow to the motor. Figure 2.1. Simple block diagram of an electric vehicle (Brant and Leitman, 2009) 2.1.2. Electric Vehicle Operation Electric and internal combustion vehicle are almost the same when it comes to operation. An ignition key or a numeric keypad powers up the vehicle’s

Full Hybrid Transmission System 1 FULL HYBRID DESCRIPTION Hybrid Electric Vehicles (HEV) differentiates from basic electric vehicles (EV) through their use of two power sources. The purpose of having two power sources is to utilize the properties of both the electric component and combustion engine to create a vehicle that’s more efficient and less environmentally damaging. Different types of hybrid systems utilise different properties of the power sources through compromise, allowing better performance
Briefly describe the difference between a “Hybrid Electric Vehicle” and an Electric Vehicle. 2 ii. With the aid of diagrams explain the difference between a Series and Parallel Hybrid Electric Vehicles. 2 iii. Research and outline the function, engineering principles and operation of the following parts of a Hybrid Electric Vehicle. Include suitable diagrams to aid your explanations. 3 • Regenerative braking 3 • Battery types used 3 • Electric motors 4 5 • Internal combustion engine (Relate the
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle.[1] The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal combustion engine and one or more electric motors. However other mechanisms to capture and utilize energy are included. Power Power sources for hybrid vehicles include: * On-board or out-board rechargeable energy storage system (RESS) * Coal, wood or other solid combustibles * Electricity *
Power Split Architecture Power-split hybrid powertrain are ones which consists of power-split device (PSD), an Internal Combustion Engine (ICE), two Electric Machines (EMs), ESS and VCC. Power-split architectures is a match between series and parallel hybrid to obtain advantages of both series and parallel hybrid architectures. The produced engine torque is split into two parts, which are further delivered to the output shaft by the means of an efficient mechanical path and another less efficient
the type of vehicles, type of batteries and battery capacities. Trips starting with full battery charge can travel using electric power alone in charge-deplete mode till the SOC level drops to about 20-30%, and once this threshold level is reached, vehicles can be supported by ICE in case of PHEVs to drive in charge-sustaining mode to maintain the SOC close to the threshold level. As the battery capacity increases, the AER range increases, also the charging time increases. The total power consumed by
