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 for the vehicles specifications. Full Hybrids, considered the most fuel efficient, can automatically swap between series, parallel and full-electric modes (further explained below) allowing the vehicle to run at full utilization and economy through different uses, such as in traffic, highway driving and racing. Examples of full hybrid vehicles include that of the Toyota Prius and many of Toyota’s Synergy Drive Hybrid range. Series powertrains refer to using an electric motor to rotate the wheels, whilst the alternate power source drives an on board generator which essentially increases the reliability of the electric motor without directly powering the wheels. Unlike series mode, in parallel mode both power sources are used to provide power to the wheels. This can be configured in a wide variety of ways by alternating the use of full-electric or full-combustions, or having different wheels powered by different sources, i.e. front wheels electric drive and back wheels
