Explanation: HYBRID ELECTRICAL VEHICLES: Today's hybrid electric vehicles (HEVs) are powered by an internal combustion engine in combination with one or more electric motors that use energy stored in batteries. HEVs combine the benefits of high fuel economy and low tailpipe emissions with the power and range of conventional…

QUESTION1: BATTERY: A Battery is a device consisting of one or more electrical cells that convert chemical energy into electrical energy. Every battery is basically a galvanic cell where redox reactions take place between two electrodes which act as the source of the chemical energy. Battery types Batteries can…

EXPLANATION: convectional vehicle: convectional vehicles use an internal combustion engine fueled by gasoline or diesel to power the wheels .In this the heat engine uses the principle of heat releases through combustion of a fuel with an oxidizer in a combustion chamber to create expanding gases which pushes against a…
