High-voltage service & safety

One place for HV isolation sign-offs, technician certifications, and battery health. Every number here is measured, not typed marketing.

HV isolation / lockout-tagoutSign off before any high-voltage work

PPE verified
Class 0 (1000V) insulating gloves inspected + in date, face shield, insulated tools, no jewelry.Service plug / HV disconnect removed
MSD or service disconnect pulled and kept in the tech's pocket, not left at the vehicle.HV system de-energized
Ignition off, key stored away, waited the OEM-specified discharge time (5+ min) for the DC-link capacitors.Voltage verified 0V at terminals
CAT III meter proven live-dead-live on a known source; 0V confirmed across HV terminals and to chassis.Lockout tag applied
Danger tag and lock applied at the disconnect; vehicle marked HV-safe with tech name and time.

Every box must be true before you sign. This is stored as a dated safety record against the RO.

Reference

EV inspection templateDrop these lines into an HV service RO

HV cabling & orange conduit
Chafed, cracked or rodent-damaged orange HV cable is a shock and fire risk. Any damage is a stop-work condition.

HV battery / inverter coolant
Low or degraded coolant lets the pack or inverter overheat, which cuts range and can trigger thermal derating.

12V auxiliary battery
A weak 12V aux battery is the #1 EV no-start cause; the car cannot close the HV contactors without it.

Charge port & latch
A burnt, loose or dirty charge port slows charging and can overheat. Check the latch, pins and seal.

Regenerative braking / brake wear
EV brakes wear slowly, so pads and rotors can corrode. Confirm regen is working and pads move freely.
