How well do you know your PHEV and BEV J1772 EVSE Diagnostics? Take this quick quiz and see!
Tech “A” says an electrified vehicle may not have a high voltage service / disconnect plug to allow for a power down when working on high voltage components. Tech “B” says some vehicles allow for a diagnostic tool to perform high voltage power downs.
Who is correct?
CAT-III certified DMM should be used whenever measuring high-voltage circuits or components. The CAT III rating relates to ________.

Ability to withstand impulse / transient voltage
Resistance to static electricity
Both a and b
Any of the following might shut off the high voltage to components and circuits, except ________.

Disconnecting the 12-volt auxiliary battery
Removing the main fuse, relay, or HV plug
Technician A says that a BEV with a displayed range of 25 miles should return to 100 % when plugged into a J1772 Level 1 charger for within 2-hours of charging. Technician B says that a DC fast charger (CCS) will take most BEVs around 1 hour to bring it’s range up to 100 %. Which technician is correct?
Technician A only
Technician B only
Both technicians A and B
Neither technician A or B
Most PHEVs will start the I.C.E. (Internal Combustion Engine) when the IPC (cluster) says “Ready” and the accelerator pedal is pushed to the floor (vehicle in Park).
