Introduction to Hybrid Drive Vehicles

What is a Hybrid? A Hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle i.e. HEV Such as a vehicle powered by both an electric motor and an internal combustion engine as a source of power for the drive train Petrol + Motor = HEV

Hybrid Vehicles, why ? Global Warming Increasing fuel prices Oil reserves If we do not try, how will we know

Hybrid Technology One of the first known Hybrid Electric Vehicles HEV was patented in Belgium in 1900 Photo of a 1912 Detroit Electric model 47

Hybrid, misconceptions ? Slow…? Poor range… ? In the 1980’s & 1990’s Formula 1 looked at H.E.V but they were considered to powerful !!

Are there other options Full electric vehicles – Require a very large battery which require a lot of power to recharge, more energy from power stations. Fuel cells – The technology is not developed sufficiently at present but in the future this may be the better option. H.E.V is the best short term answer.

Hybrids can and are being serviced, but adhering to extra H/S requirements are essential The threshold for voltage that can be fatal is 60 volts, but for some people that may be as low as 50 volts. Orange cable code indicates upwards of 60 volts. ! In Reality there is 200-650 v ! Warning – Never carry out any work on a Hybrid vehicle unless your qualified to do so and have the correct Health and Safety Equipment
