EV Quiz 2

Most drive motors used by electric/hybrid vehicles contain:

• Armature Windings

• Switched Reluctors

• Rectification Diodes

• Permanent Magnets

The Europe wide common charging coupler system for electric vehicles is known as:

• Type 1 Charging Plug

• Type 2 Charging Plug

• The High Voltage Charging Plug

• The 3 Phase Type Charging Plug

Under which driving condition would the electric motor assist the powering of a parallel hybrid vehicle, assuming the state of charge is sufficient?

• Pulling away from stationary, braking, cruising

• Climbing inclines maintaining top speed braking

• Rapid acceleration, braking and when stationary

• Rapid acceleration when overtaking, normal cruising

Under what conditions does a regenerative braking system recover energy?

• Acceleration and braking

• Braking and deceleration

• Stationary and accelerating

• Decelerating and accelerating

What should you do if a charging cable from a electric/hybrid vehicle is found to be frayed or damaged prior to connecting to an external source?

• Connect to the external source as normal

• Do not connect the cable to the external source

• Insulate damage to the cable and connect to the external source

• Try to repair fray or damage and then connect to external source

What are the two main precautions you must take before performing any work on or near the high voltage system?

• Remove the ignition key and lock the doors

• Read the fault codes and clear any faults found

• Turn off the ignition and check the auxiliary battery voltage

• Isolate the high voltage system and wait the appropriate time

How can you ensure that the high voltage system is safe to work on following the isolation procedures?

• Touch the circuit with your finger briefly

• Use a voltmeter connected across the battery

• Turn on the ignition and see if the dash light come on

• Follow manufacturers information to check no high voltage present

If an EV needed to be heated in a spray booth what precaution should be taken?

• Remove HV cables

• Remove HV battery

• Insulate the drive motor

• Mask off the inverter assembly

A multimeter and test leads/probes used on a hybrid vehicle must be a minimum of:

• CAT III 100 Volts

• CAT III 250 Volts

• CAT III 500 Volts

• CAT III 1000 Volts

When connecting an EV to a HV charging point it is essential that:

• The vehicle low voltage battery is disconnected

• Manufacturers charging procedures are followed

• The vehicle cabin preheating system is switched off

• The vehicle is switched on, so the driver interface is visible
