A Seminar On
HYBRID CAR

2. WHAT IS A HYBRID?
 A hybrid is a vehicle that is propelled by two
power sources.
Internal combustion engine (ICE)
+
Electric motor powered by batteries.

LEVELS OF HYBRID VEHICLES
 Full hybrid
 They feature idle-stop function
 Regenerative braking
 Most are capable of using the electric motor
alone to propel the vehicle
 The electric motor also assists the engine
 Battery voltages are about 200 to 300 volts

5. 5
LEVELS OF HYBRID VEHICLES
 Medium hybrid
 They feature idle-stop function
 Regenerative braking
 Most are not capable of using the electric
motor alone to propel the vehicle
 The electric motor usually assists the engine
 Battery voltages are about 144 to 158 volts

6. 6
LEVELS OF HYBRID VEHICLES
 Mild Hybrid
 They feature idle-stop function
 Regenerative braking
 Are not capable of using the electric motor to
propel the vehicle
 These systems are usually 42 volts or less

7. BASIC COMPONENTS
 Power plant ICE
 Electric motor / Generator
 Battery
 Transmission
 Inverter

8. 8
TYPES OF HYBRID VEHICLES
 Series hybrid
 Vehicle propulsion is by a electric motor only
 ICE is used for charging the HV battery

9. SERIES HYBRID

10. 10
TYPES OF HYBRID VEHICLES
 Parallel hybrid
 Uses multiple propulsion energy sources
 This means the electric motor and ICE propels the
vehicle

11. PARALLEL HYBRID
11

12. 12
TYPES OF HYBRID VEHICLES
 Series-parallel hybrid
 These vehicles can operate using the electric motor
alone or with assist of the ICE
 They combine both functions of series and parallel
design

13. DRIVE MODES OF OPERATION

14. MAINTENANCE
 Hybrid vehicles require the same
maintenance as regular vehicles
 However, some hybrids require inverter
flushes and battery filter changes.
 There be additional costs involved in
replacing low rolling resistance tires.
 Vehicle repairs may cost more than a regular
vehicle

15. HOW LONG WILL A HIGH VOLTAGE BATTERY
LAST?
 Most hybrid high voltage batteries last
180,000 to 240,000 miles
 Manufacture battery warranties
 Honda
 8 years / 80,000 miles
 Toyota
 8 years / 100,000 miles
 Ford
 8 years / 100,000 miles
 General Motors
 8 years / 100,000 miles 15

16. ARE HYBRID VEHICLES SAFE?
The following will disable the high voltage system
 High voltage interlock circuit
 Airbag deployment
 High voltage leak
Removing battery negative

17. WHAT HAPPENS IF A HYBRID VEHICLE IS
SUBMERGED IN WATER?
 There is no risk of electric shock from
touching the car's body or framework—in
or out of the water.

18. ALL ELECTRIC VEHICLE PERFORMANCE
 Speeds range from 25-90+ mph
 Distances per charge range from 25-250 miles
 Equivalent mileages @ $4.00/gal gas:
• Cars 100-200 mpg
• Motorcycles 200-400 mpg
 Considerably less maintenance/complexity
• No fluids, muffler, water pump, oil, belts, starter
• Longer life brakes (regen), less heat degradation
• No stops at gas station or oil changes, starts in winter,
fewer places to pay bills (home electric bill)

19. ADVANTAGES DISADVANTAGES
 Better mileage
 Improved acceleration
(most of the time)
 Less dependence on fossil
fuels
 Lower emissions
 Some states provide
incentives for driving a
hybrid
 Great driving experience
 Little highway mileage
increase
 High initial cost
 Needs high fuel cost to be
worthwhile
 Could cost more to repair
 Extra maintenance items
 Some hybrids need special
tires
