New round for Gr.15

Who developed the first gasoline-powered automobile?

• Henry Ford

• Gottlieb Daimler

• Carl Benz

• Nicolaus Otto

What are the main requirements for customer's acceptance of electrified vehicles?

• Zero emission

• Charging infrastructure

• Low noise

• Costs

Which advantages of electric vehicles from customer's point of view are important?

• Car can be be charged ("filled up") at home

• Top speed

• Air condition can be used even if the car is not occupied

• Improved acceleration

Which statement is true for Hybrid vehicles (HV) ?

• Battery can be charged via power socket

• Short distances can be powered by electric power

• No local emissions

• Maximum torque as soon as the wheels start to turn

• None of the above

Which statement is true for a Plug-In Hybrid Electrical Vehicle?

• Extremely low fuel consumption

• No tank filler neck

• Can be driven purely electric

• Battery can be charged externally

What is a range extender at electric cars?

• The mechanical drive train in case of an empty battery (emergency mode)

• A small conventional internal combustion engine

• Charging the battery during driving when the energy runs low

• Generator supplies electrical energy to the electric motor

Which statement is true?

• The electric machine can be used as motor and as generator

• The High Voltage (HV) battery needs DC voltage for charging

• The power electronic needs no extra cooling

• The High Voltage (HV) stores AC voltage

Which statement is true?

• Fuel cell can be charged at quick charging stations

• Modern combustion engines are downsized using direct injection and turbo charging to reduce CO2 emissions

• Fully Hybrid cars can drive short distances using the electric motor only

• Fully Hybrid cars are using synchronous motor

What has to be considered in the High Voltage technology inside the Service area (workshop)?

• Wearing rubber boots and rubber gloves is sufficient

• Additional qualification required

• Mechanics working on EV have to be tested for being color blind because electric cars have many color coded warning signs
