Maintenance

Types

• OEM factory - dealer • Third party – repair shop - ASE• Do-it-yourself

Maintenance

• Hybrid EVs with ICE are similar maintenance to conventional vehicles

• All-electric vehicle typically require less maintenance than conventional vehicles

• Braking systems typically last longer due to regenerative braking

• Electric System does not require scheduled maintenance• Batteries have limited number of charging cycles based

on chemistry as defined by OEM

Safety Programs

EV Standards and Codes for OEM

• Must Meet Federal Motor Safety Standards by NHTSA– www.access.gov/nara/cfr/waisidx_49/49cfr571_09.html

• Current FMVSS Title 49 standard 305 – – www.nhtsa.gov/cars/rules/rulings/lsv/lsv.htm

• Safe Car Designs – www.safercar.gov• Safety Citation – www.afdc.energy.gov/afdc/pdfs/48605.pdf• Emergency –

Safety Practices

EV Standards and Codes for OEM

• Undergo the same testing as conventional vehicles • Battery packs –encased, sealed, impact, stress• Test – overcharge, vibration, temperature, fire, collision• Wired for insulated high-voltage lines and color coded• Damage – safety deactivate electric systems• Limit electrolyte spillage from batteries during crash• Charging disconnects motor starter when plugged-in • Charging cable brake-away/disconnects from charger driving

Safety Design Factors: High-Voltage Systems

Has two separate electrical systems A low-voltage system (12-volt DC) powers the accessories and

the SLI. A high-voltage system (>60 volts) powers the motor generator

(MG). The high-voltage system can be up to several hundred volts

so never cut them.

Identification: Under the Hood

Under the hood, the voltage inverter will have decals or markings as indicated.

There may also be a marking or decal on the engine cover. Wires will be color coded

General Reminders

Even when the ICE is off, high voltage may be present. The ICE may start at any time unless disabled. (smartkey) HEVs can be treated much like any other vehicle in an

accident. Disconnecting the 12 volt battery disables high-voltage

controller

NAFTC

Crash and Fire Procedures

Vehicle fires can be handled like any conventional vehicle except in the case of a battery fire.

In the event of a battery fire of the high-voltage battery system, use large volumes of water to help to cool battery cells around the burning cells.

Do not attempt to open the battery pack.

Use extreme caution when working in wet or damp areas

Do not cut any orange (high-voltage) cables.

Vehicle Occupant Safety

Primary risks are the same as a conventional vehicle.

The risk of exposure to toxic battery materials is low. Even in the event of catastrophic battery damage, the release of the electrolyte will be small.

In the event of exposure, flush with water.

Potential airbag deployment must be considered.
