EV 2.1 Assessment

Vehicles or batteries damaged by fire or impact can result in increased exposure to these risks, except :

• Flooded in water

• Electric shock

• Temporary deafness

• Chemical burn

What is the safety precaution before approach EV and hybrid vehicle that not related ?

• Buffer zone

• Warning sign

• Safety barrier

• Potential bonding

• Lock out box

What is the function of buffer zone ?

• Prevent overheating of charging system, which can lead to fire

• Prevent lot of electrical energy transfer into HV battery

• Warning technicians and others of any potential threat, including electric shock

• All of the answer

• None of the answer

What is the function of lock out box ?

• Warning technicians and others of any potential threat, including electric shock

• To put critical components such as ignition key or service plug

• Prevent lot of electrical energy transfer into HV battery

• All of the answer

• None all the answer

What assessment need to identify when making connection for charge the EV ?

• Check the charging point of vehicle is not damaged

• Check the charging cable is not damaged

• Ensure cable is not lying across a walkway and trip hazard

• All of the answer

• None of the answer

What is the hazard when handling HV battery ?

• Smoke extraction must work particularly and burning vehicle must be retrieved from its parking space if possible to keep technician working on vehicle safe

What does an open circuit refer to in electrical terms ?

• A circuit where electricity flows continuously without interruption

• A circuit with a high resistance that limits the flow of current

• A circuit where voltage is applied but no current is drawn

• A circuit where there is a gap or break, preventing the flow of electricity

• All of the answer

What is a closed circuit in electrical terms ?

• A circuit with a high resistance that limits the flow of current

• A circuit where there is a gap or break, preventing the flow of electricity

• A circuit where electricity flows continuously without interruption

• A circuit where all components are connected in series

• All of the answer

What is the primary function of a High Voltage Disconnect Device, specifically a Service Plug ?

• To provide a secure connection between electrical components

• To disconnect high voltage power sources for maintenance or servicing

• To increase voltage output in electrical circuits

• To regulate the flow of current in low voltage systems

• All of the answer
